OBTAINING THE SOFTWARE AND THE HARDWARE 4 If you want to build your own Chronopic please check the section Hardware at the web page: http: //chronojump.org/documents.html#hardware For more information consult the frequent questions of the software (FAQ) org/faq_hardware.html http://www.chronojump. Chapter 3 Con guring Chronopic Chronopic is an integrated circuit used by Chronojump to detect the test done at the detection device. To obtain the Chronopic please check section 2.3. For more information about Chronopic consult the web page: http://chronojump.org/documents. html#hardware Current Chronopic version is Chronopic3 ( g 3.1). Figure 3.1: Chronopic3. 3.1 Chronopic connections Chronopic 3 is a USB powered hardware. Using USB cable it receives data from PC and also power. To complete the connection, this cable will also be connected to the socket. Chronopic will be connected to the contact platform or photocell barrier through the RCA connection , the terminal block or both. Using Chronopic RCA (and / or fuse) it is possible to connect 'n' networking platforms to any Chronopic. This model is useful to chronometer situations where an athlete should not be able to be in more than 5 CHAPTER 3. CONFIGURING CHRONOPIC 6 one platform at the same time. Both cables of each platform must be connected to the RCA connector or the terminal block. Software allows the connection up to 4 Chronopics with an independent signal, each connected to one or more sensing devices. This makes possible chronometer independently various subjects, complex paces or other applications. 3.2 Chronopic working process Chronopic detect changes in the contact platform and sends it to the computer by USB cable, USBserial or serials. You can also use the test button to simulate changes in the platform. Chronopic has a green light to indicate when the subject is on the platform or the photoelectric barrier (light stays o ) or outside (light is on). 3.3 USB ports The operating system assigns names to ports, as shown in Table 3.1. Operating system Port Name Comments MS Windows USB COM1, COM2, COM3, ... (seen Driver required to COM27) GNU/Linux USB /dev/ttyUSB0, /dev/ttyUSB1 Table 3.1: Names of each operating system port. The most common names are in bold type text. The use of the driver is explained in the next section. 3.3.1 Windows USB Driver A driver is a small program that indicates the computer how to operate a new device. Chronopic plate requires a driver to run on Windows. This driver is automatically installed when you install any version later than Chronojump 0.7. If you connect the Chronopic to the computer, and it's detected "New hardware found", then the driver is not required, in other case it will be necessary to run the driver. 3.4 Modi cation port assigned by Windows If the port assigned is COM5 or higher it may cause problems in some computers detection. If this happen, it's recommended to assign a lower port than COM5, preferably COM1 or COM2. To manually assign a port, repeat the steps described in the following steps: 1. Click "Port Settings". ?? to know which port is assigned, then do CHAPTER 3. CONFIGURING CHRONOPIC 7 2. Click on "Advanced Options". 3. Select one of the ports COM1-4 (preferably COM1 or COM2). 4. Accept and close the assistant. 5. Disconnect the USB cable and reconnect it after a few seconds. At this point it should be assigned a COM port that device that will last forever. Alternatively, return to perform the steps described in ?? to verify that the change was made directly. En este momento ya debería tener el puerto COM asignado para siempre a dicho dispositivo. Opcionalmente, si quiere puede comprobar que el cambio se ha realizado directamente puede volver a realizar los pasos descritos en ??. 3.5 Chronopic solution problems In case of detection failure when changing Chronojump platform, we propose the following battery of tests. If Chronopic is not working after performing these tests, please noted at the Forum http: //foro.chronojump.org. Perform each of the tests until it's working correctly. Remember to check that the cables are connected properly. 1. Power Problem: The red light will turn on when you connect the USB cable (this will happen when the computer is turned on except when there is a connected platform and someone stepping on it, or pushing the test button ). 2. Problem networking platform: Connect the contact platform to Chronopic and the Chronopic to the computer (no need to open chronojump)and check the Chronopic by clicking on the platform and checking if the light turns on and o. If the light doesn't turn on and o, but it did in the previous step, then the cables are in touch when they are connected to Chronopic. Insulate them, check if they are poorly connected or if the platform has a bad contact (disassemble and repair). 3. Port problem on Windows: If the contact platform doesn't have any problem, unplug it and continue the testing only with the Chronopic. Then, check if the port is detected and connect the cables to the computer, the power should also be detected in the Chronopic as described in Section ??. Windows may detect more than one type of port COM, do the following test to both. If the port assigned is higher than COM4, it's recommended to modify the port to one less than COM4, preferably COM1 or COM2 as described in Section 3.4. 4. Execute Chronojump, select the port con guration in the Chronopic window. A dialog will appear asking you to click "OK" and after this click on the button Chronopic, shortly Chronopic should be detected and ready to be used with the platform connected if desired. Part II Using Chronojump 8 Chapter 4 Using Chronojump When Chronojump is opened, a window will allow you to select the type of tests you are gone to work with. Figure 4.1: Chronojump splash screen. Once you have selected, if you want to go back to this windows you can go to Menu -> Mode: -> Main window You can also con gure some parameters related to the automatic hardware detection. If you experience problems at start or while capturing try the dierent options. 4.1 Chronojump main window When chronojump is opened you will be asked the mode you want to work with. Chronojump has 4 modes and in each one there is a lot of diferent tests. 9 CHAPTER 4. USING CHRONOJUMP 10 Figure 4.2 shows Chronojump main window. This is divided into the following parts: The menu where you nd the access to session and help. Edit subject provides a quick access to individual operations. Subject selection where you can select the subject and edit it with the menu that appears when you click on the right button of the mouse. Chart selected test If there is a drawing of the test selected or targeted by the mouse, it will be shown. Also, if the program has expanded information on the test, displays an icon to indicate it. By pressing this button it will display a help window on this test chart containing the expanded and test information. Tabs that allow you to change the work form: Contacts (platform of photocell), Encoder and Server. Test type with the functionality of executing each of the tests on the tab or active labor module. Viewing and editing the tests shows dierent selectors for viewing and editing the jumps and runs. User Noti cation displays information about the last action.

(Top-right corner of the window) see gure 4.5. CHAPTER 4. USING CHRONOJUMP 11 Figure 4.3: Session Menu. Figure 4.4: Mode Menu. Figure 4.5: Help Menu. 4.3 Chronopic/s Connection. Is possible to connect one or more Chronopics on the menu: Tools / Chronopic. In Figure 4.6 two Chronopics connected are shown. There is a help button for the ports by clicking on the Help button window. The connection to the Chronopic timer is speci cally addressed in section 3. If the rst Chronopic is activated, the rst circle will be green. You can connect more than one to perform tests in Multi Chronopic. When you select the port, you must click on the right button to make the connection. In each successful activation the red circles will become green. 4.4 Database: sessions, subjects and tests Chronojump stores all data in one database le. Thus, instead of collecting the information in individual les for each session, all information is organized in a single le to facilitate the study of relationships between: sessions CHAPTER 4. USING CHRONOJUMP 12 Figure 4.6: Chronopic connection. The gure corresponds to the program Chronojump-in version for Linux operating system, which are connected with two Chronopics. CHAPTER 4. USING CHRONOJUMP people tests (jumping, running, reaction times, pulses (rates), multi Chronopic) 13 All modi cations in session, subjects and tests, will be updated at any time in the database. So there isn't need to save the information periodically and make data loss to a computer error. If rare case, the program crash, you wouldn't lose any data except sometimes the one that is being performed at the time. 4.4.1 Sessions The sessions represent situations where the coach or evaluator gathers many athletes (subjects) for a series of tests. Every time you gather a group of athletes to be tested in a short space of time (usually one day), you should create a new session. Although the subjects to assess are the same as in other session, you should create a new one to keep adding subjects and tests in an old session. In this way, you can make comparisons between data. Figures 4.7 and 4.8 demonstrate the creation of a session. Figure 4.7: New Session. School students. CHAPTER 4. USING CHRONOJUMP 14 Figure 4.8: New Session. Rhythmic competitors. 4.4.1.1 Creation Click on the menu Session menu / Create session and one window will be opened where you must enter the name of the session, the date and the sport practiced. Optionally you can also indicate the place where is done and even add comments. 4.4.1.2 Load If you want to load a session already created to study, add subjects and / or to test, click on the Session menu / Load session. It will show a list of sessions created and information of the subjects enrolled in each of them and the tests performed. 4.4.1.3 Edición Click on Session menu / Edit session to modify the parameters that have been inserted earlier. Normally, it's used the edition of sessions to add comments about the evolution. CHAPTER 4. USING CHRONOJUMP 15 4.4.1.4 Delete To delete a session and all tests performed, click on the Session menu / Remove session. A con r- mation window will appear. 4.4.2 subjects All individuals able to perform the tests are known as subject. It's strongly recommended to create one subject only once in order to study the evolution over time. In following sessions the subject must be loaded. Figure 4.9 shows the creation of a person. Figure 4.9: Creation of a person. 4.4.2.1 Current person The subject on the left side of the main window is known as current person. All tests done shall be linked to that subject. The latter subject created or loaded is assigned as current person. Tests shall not start until the current person is assigned. CHAPTER 4. USING CHRONOJUMP 16 4.4.2.2 Creation Click on the Person menu / Create person or use the Create button to create a person. You may indicate the full name, gender, date of birth, height, weight, country, sport, mode and level. It's important to enter the full name to avoid further con icts with other dierent subjects. In order to accelerate the creation of multiple subjects, click on the menu Subject / Create subjects [multiple]. A window will appear where you can create multiple subjects at once. You can choose between Add entries from CSV (spreadsheet) or Add entries manually. In the rst case you will need a coma separated value le (.csv) previously created with the information of the name, surname, genre and weight in diferent elds. The format of the le can be speci ed with headers or without it . Additionally you can have a le with a single column for the full name or two columns for the name and surname . In the second case, you can create manually a set of subjects as shown in the gure. Once created, if you still want to create more subjects, you can click again on the same menu item. Figure 4.10 shows the creation of 11 subjects at once. Figure 4.10: Load subjects. 4.4.2.3 Load If a person has participated in another session, and you want to evaluate him/her again in the current session, click on Load person, and enter the same subject to the new session. The program will distinguish between tests (jump, run, reaction times and rhythms) made by the same person in two or more sessions. If you created a session and you want to continue with the same person/s in another session click Load subjects from another session and check all subjects who participated in the other session or multiple session. If you wish you can always discard any subject. Figures 4.11 and 4.12 show the load of subjects. CHAPTER 4. USING CHRONOJUMP 17 Figure 4.11: Load subjects.

You can also select other subjects of the current session. 4.4.2.5 Edit Click Edit person or press p (person) to modify the data that was entered at the same time as the creation. You can also add comments. CHAPTER 4. USING CHRONOJUMP 18 4.4.2.6 Delete Click Delete current person to be removed of the session. This operation will remove all tests from any person in the current session. It's important to know that the subject will not be removed from the database and the tests in other sessions remain intact. After deleting this subject, another subject will become the current person. Otherwise any test can be provided. 4.4.3 Tests So far Chronojump manages ve types of tests: jumping, running, reaction times, rhythms and MultiChronopic. Later Chronojump can handle other tests. These tests are detected by the signals sent by the contact platform when the subject steps on and o it. The database stores the tests and links to other data tables. Chapter 5 Tests At the following text, it describes the management of the all types of tests allowed in Chronojump software. 5.1 Jump tests There is basically two types of jumps: simple and repetitive. Chronojump detect a single jump as one phase of ight. That's why there are two types of simple jumps: 1. Those who start and nish on the platform (single hop).We obtain the variable ight time (TF) 2. Those who started outside the platform (drop from a height or do a jump before) to fall on the platform and then jump. Variables obtained: Contact time (TC) (time between reception and takeo on the platform) and ight time (TF). Usually jumps will pursue minimum contact time and maximum ight time as a power indicator. A multiple jump (also called reactive) is when you obtain more than one ight time. For example: make two consecutive jumps initiated on the platform in the order TF, TC, TF or start outside the platform and continue with the order TC, TF, TC, TF. Assuming that the body during the takeo position is the same as in the landing, the ight time indicatives the height of center of gravity of the athlete in this jump. Videotutorial: Right execution of the Bosco Tests https://youtu.be/wa6-KgTOwkw 5.1.1 Simple jumps execution From the Simple Jumps button, you can select from the drop-down list the following options: Free, normal jump without restriccions SJ, Squat Jump SJ l, Squat Jump with extra load (extra weight) CMJ, countermovement jump CMJl, coutermovement jump with extra load (extra weight) 19 CHAPTER 5. TESTS 20 ABK, jump with arms Abalakov ABKl, jump with arms Abalakov with extra load (extra weight) D Ja, drop jump with arms using DJna, drop jump without arms using Rocket, Rocket Jump is simple jump similar to the squat jump but it starts with a full exion of the legs. TakeO, only records the contact time TakeOWeight, take o with extra load. It only records the contact time slCMJleft, left leg countermovement jump. slCMJright, right leg countermovement jump. Sometimes you will be asked to provide additional information as the extra weight of the subject (SJL) or the height of the drop (DJ). The original protocol of Bosco for the DJ test indicates that the arms don't participate in the jump. Instead many coaches ask their athletes to use the arms because is more similar to the techniques used in sports. The original DJ is called DJna (no arms), while the DJ with arms is called DJ a. When you start a DJ test, the program will ask whether to use arms or not and automatically appoint the jump properly. If Chronopic has not been connected and activated from Chronopic window, a jump will be simulated. In the other hand, if Chronopic is connected, real jump will be done. Note that for some jumps the athlete should be on the platform, while other jumps it's essential to be elsewhere. You will be noti ed if the athlete's situation is not correct. The progress barr shows the progress of the jump, which may be stopped by clicking on the Finish or Cancel button. 5.1.1.1 Automatic mode In order to accelerate the process of testing multiple subjects you can click on the Automatic mode button. This mode allows you to perform tests creating or loading sequences of diferent jumps or people. De ning the sequence can be done either loading a precon gured one (Load sequence ) or creating a new one (Create new sequence). When a new sequence is created the order of the test must be de ned. There are three dierent options: By persons : Each person of the session performs all the tests before changing to the next person. Example: Chronojump pro le. By tests : Each test in the sequence is perfomed by all the people in the session before changing to the next test. Example: Bilateral pro le by persons By sets : Each person of the session performs the rst set of tests before changing to the second set of tests. It can be de ned up to 3 dierent sets of tests. Example: Bilateral pro le by sets CHAPTER 5. TESTS 21 To de ne a new sequence click on the type of sequence it is about to be created and click on the Next button. Then, in the new window, the order of the tests can be de ned. If the By sets option was selected, each set must be de ned separately. After de ning the sequence, it can be saved clicking on the Save button. Once the Next button is pressed a new windows will show the whole sequence indicating the order of the person and the test. When the Accept button is pressed the automatic mode is activated. In this mode the person frame will be disabled and the name of the next jumper and what test is going to be done will be shown in the upper left corner of the Capure frame. The selection of the test will also disappear, not allowing to change After performing each jump test, the person and the test will change automatically. Clicking on the See order button the whole sequence of the test can be viewed. To skip all the tests of a person and execute it at the end of the sequence click on the Skip To delete a person from the sequence click on Remove button . . Clicking on the End automatic mode will return to the normal way of work of Chronojump, allowing you to select the person and the test to be performed. 5.1.2 Repetitive jumps execution Click in the button on the Repetitive jumping tab: RJ(j), Repetitive Jump (jumps) or repetitive jumping limited number of hops Rj(t), Repetitive Jump (time) or time-limited repetitive jumping RJ(unlimited ), unlimited repetitive jumping. RJ(hexagon), reactive jump on an hexagon until three full revolutions are done. Triple jump, triple jump starting from a falling height Unlimited multiple jump with extra load Sometimes is necessary to provide additional information as the height of the initial drop, the extra weight or value of the limiting factor (hops or seconds). Click on More to get a list of all the available of the reactive jumps and execute them clicking OK. The jump menu also provides access to these actions. If Chronopic has not been connected and activated from Chronopic window, a jump will be simulated. In the other hand, if Chronopic is connected, real jump will be done. Note that for some jumps the athlete should be on the platform, while other jumps it's essential to be elsewhere. If you want to execute the same type of jump to various subjects and you don't want a button (only available on the tab more), you can change the subject and use the Last button to allow another person to perform the same jump. CHAPTER 5. TESTS 22 Figure 5.1: Bells - auditive and visual feedback. 5.1.3 Auditive and visual feedback in repetitive jumps: bells In order to add a visual and auditory feedback during execution of the jumps, you can set values of ight time, contact time, or the relationship of both. To be shown a red bell (poor performance) or green (good performance) together with a distinctive sound. Click on the "Bells" to con gure these actions as shown in Figure 5.1. 5.1.4 Jumps view Simple jumps are shown on the Jumps tab and the reactive Jumps on the Jump Reactive tab. In both cases, it's included a lter for all the possible tests or only a particular type. Tests are associated with the jumpers. The order of the tests presentation of each jumper is chronological so, the last test appears at the end of the list. It's included a button that allows sorting the tests by the type of jump and not in chronological order. All jumps are selected in the view lter. A series of values are presented at each hop. It's possible to change the view by accessing at the Preferences (more information in section 9.1 en la página 73). You can use the magnifying glass button (or press z ) to facilitate the view of the tests. 5.1.5 Jumps edition You can add comments to a jump or change the person (if you forgot to change the current person previously) If you select the desired jump and click on the Edit button on the selected jump, you can also nd it on the menu, or by pressing the button e. In the reactive jumps, since they are composed of a set of jumps, this change will aect all the jumps even if only one is selected. 5.1.6 Repair repetitive jumps Using Repair selected button or pressing r, you can add a jump, modify a contact time or ight time or delete a jump. If a repetitive jump type has been de ned to be limited to max n jumps, or max n seconds, this conditions will limit the repair functionality. information text on the bottom of the window. When this happens, you will nd an CHAPTER 5. TESTS 23 5.1.7 Jumps delete To delete a jump, select it and click the Delete selected jump button. Its equivalent in the menu or press d (delete). By deleting the test you will be asked to con rm it if the delete con rmation option is activated in the Preferences menu (more information in section 9.1 en la página 73). Deleting a repetitive jump will delete all it's jumps. 5.1.8 Creation of new jump types In order to adapt the software to the needs of each user, it has been included the function: Add jump type (on Jumps menu). This allows trainer to de ne easily and powerully the desired jump types. Created jump type will be available on database to be used at any session, and it will be listed clicking on the More button at the Jump or Jump repetitive tabs (depending on which kind of jump it's created). This new jump type will be also dierentiated on statistics, graphs and reports. On creation, you should give it a distintive name and classify between simple or repetitive. If jump is repetitive, then you can limit is by jumps, time, or leave it unlimited. The limit by time or jumps options can be de ned as a xed value or leaved as unde ned. If it's de ned xed, all new jumps of this type will be limited to that value; in the other hand, if the type is not xed, user will be asked by limit value everytime a new jump is done. Last settings include: start inside or outside the platform, allow to jump with an extra weight, and add a description to the jump type. In the gure 5.2 you can see the creation of new jump type. Figure 5.2: Creation of a new jump type. 5.1.9 Examples on creation of new jump types Here you can nd some examples on creating new jump types. The names of the types have been invented in this manual. The table 5.1 is also useful to understand the dierent variables. CHAPTER 5.

If the run is circular, it can be used a single device (platform or photocell), in the other circuits, there's a need of more than one detection device (of any type). From now on, device in contact means that the person is on the platform or blocking a photocell signal. Is important to note that the person should never be in contact in more than one device at the same time. The gure 5.3 shows a drawing of the position of two platforms to measure run. In order to calculate average speed, user will be asked about the distance between platforms. Runs can be of two types: simple and repetitive. On Chronojump a only one track. There are two kinds of Running from stop simple runs: simple run means that there's Start on contact in a device and end in contact in the same or other device. Running with initial speed Start before the contact, after a while, a contact is done and chronometer starts, then person leaves the detection device until it produces contact again. This allows to measure a run where person has an initial speed. In both situations, the registered data is the time between one device and the other, also speed will be calculated. An intervallic run is a run where there's more than one track, it should be understanded as run along two or more tracks limited by devices at a xed distance. CHAPTER 5. TESTS 25 Figure 5.3: Drawing of two platforms circuit to measure run. 5.2.1 Correction of multiple contacts Chronojump allows to x the situations where the subject activates the contact device more than once due to dierent parts of the body contact the device in dierent instants. (example: an athlete arrive to a photocell, makes contact with a hand, ends the contact and after that make contact with body). To prevent this type of situations in Menu -> Preferences -> Runs check Prevent double contacts This dialog box allows to set the minimum time between contacts to be considered as correct. If the time between contacts is lesser than the con guration in the dialog Chronojump will act as set in the selected option ( rst, average or last) 5.2.2 Simple runs execution To execute a simple run, click the following buttons on Runs tab: Custom to run after introduce the track's distance 20m-400m, to run on the preselected track's distance Agility runs, this tests are available: 20 Yards, 505, Illinois, Shuttle Run, Zig-Zag test. The gure 5.5 shows the information available on software about the 505 test. Click on More to see all simple runs available, and execute them clicking Ok. If Chronopic has not been connected and activated from Chronopic window, a run will be simulated. In the other hand, if Chronopic is connected, real run will be done. Software allows to start run in contact with the device or before the contact. On the later situation, time between starting of the run and contact on the rst device is deleted. In the pop-up window it shows the progress of the run, which may be stopped by clicking on the Finish or Cancel button. If you want to execute the same type of run to various subjects and you don't want a button (only available on the tab More ), you can change the subject and use the Last button to allow another person to perform the same run. CHAPTER 5. TESTS 26 Figura 5.4: Double contact con guration 5.2.3 Executing intervallic runs To execute an intervallic run, click the following buttons on Intervallic Runs tab: By tracks : intervallic run limited by number of tracks By time : intervallic run limited by number of tracks Unlimited : unlimited intervallic run At som run types, user interaction will be needed, like track distance and limit factor: tracks or seconds. Click on More to get a list of all the available of the intervallic runs and execute them clicking OK. The run menu also provides access to these actions. If Chronopic has not been connected and activated from Chronopic window, a run will be simulated. In the other hand, if Chronopic is connected, real run will be done. Software allows to start run in contact with the device or before the contact. On the later situation, time between starting of the run and contact on the rst device is deleted. In the pop-up window it shows the progress of the run, which may be stopped by clicking on the Finish or Cancel button. If you want to execute the same type of run to various subjects and you don't want a button (only available on the tab More ), you can change the subject and use the Last button to allow another person to perform the same run. CHAPTER 5. TESTS 27 Figure 5.5: 505 Agility test. 5.2.4 Feedback auditive and visual at the intervallic runs: bells Similarly to the repetitive jumps, you can con gure minimum and maximum values dor each track. A red bell will be shown on a bad execution, and a green bell on the opposite, also a distintive sound will be played. Con gure this actions clicking on Bells. 5.2.5 Runs view Simple runs are shown on the Run tab and the intervallic runs on the Run intervallic tab. In both cases, it's included a lter for all the possible runs or only a particular type. Tests are associated with the runners. The shown order of the tests of each jumper is chronological so, the last test appears at the end of the list. It's included a button that allows sorting the tests by the type of run and not in chronological order. It's possible to change tests view by accessing at the Preferences (more information in section 9.1 en la página 73). You can use the magnifying glass button (or press z ) to facilitate the view of the tests. 5.2.6 Runs edition You can add comments to a run or change the person (if you forgot to change the current person previously) If you select the desired run and click on the Edit button on the selected run, you can also nd it on the menu, or by pressing the button e. CHAPTER 5. TESTS 28 In the intervallic runs, since they are composed of a set of runs, this change will aect all the runs even if only one is selected. 5.2.7 Repair intervallic runs Using Repair selected button or pressing r, you can add a track, modify a time or delete a track. If an intervallic run type has been de ned to be limited to max n tracks, or max n seconds, this conditions will limit the repair functionality. When this happens, you will nd an information text on the bottom of the window. 5.2.8 Runs delete To delete a run, select it and click the Delete selected run button. Its equivalent in the menu or press d (delete). By deleting the test you will be asked to con rm it if the delete con rmation option is activated in the Preferences menu (more information in section 9.1 en la página 73). Deleting an intervallic run will delete all it's tracks. 5.2.9 Creation of new run types In order to adapt the software to the needs of each user, it has been included the function: Add run type (on Runs menu). This allows trainer to de ne easily and powerully the desired run types. Created run type will be available on database to be used at any session, and it will be listed clicking on the More button at the Run or Run intervallic tabs (depending on which kind of run it's created). This new run type will be also dierentiated on statistics, graphs and reports. On creation, you should give it a distintive name and classify between simple or intervallic. If run type is intervallic, then you can limit is by tracks, time, or leave it unlimited. The limit by tracks or time options can be de ned as a xed value or leaved as unde ned. If it's de ned xed, all new runs of this type will be limited to that value; in the other hand, if the type is not xed, user will be asked by limit value everytime a new run is done. User can also x the distances of the tracks. La ventana de creación de nuevo tipo de carrera concluye con la posibilidad de añadir una descripción textual. En las gura 5.6 y 5.7 puede observar la ventana de creación de nuevos tipos de carreras. Last settings include: x the distance of the tracks, and add a description to the run type. In the gure 5.6 you can see the creation of new run type. From Chronojump version 0.9, you can create intervallic runs with variable track distance. This is suitable to calculate speed in the dierent tracks of agility tests. 5.2.9.1 Examples on creation of new run types Here you can nd some examples on creating new run types. The names of the types have been invented in this manual. The table 5.2 is also useful to understand the dierent variables. Sprint10 10 meters of sprint run.

If you broke your encoder contact us at hardware@chronojump.org Please follow this CHAPTER 5. TESTS 30 Figure 5.7: Creation of a new run type with variable tracks. 5.3.1.1 Safety magnets Fix the encoder on iron or metal surface like the weights on a gym. Note some gym weights are covered with rubber and have not magnet power. 5.3.1.2 Do not release Do not release the wire when it is extended because it will return at high speed and will break. 5.3.1.3 Handle the carabiner with care Allways be careful when manipulating the carabiner. Ensure that it is well secured in your ngers. A wrong grab could end up with a broken encoder. When possible, try to put a nger inside the carabiner to avoid it slipping from your ngers. 5.3.1.4 Measure wire length Measure with care (not pulling with the ngers) the length of the wire and the maximum range of the analysed movement. Do not do tests that can exceed the wire length. Note you can x encoder to a table or other place if needed. 5.3.1.5 Perpendicular use Perpendicular use: Encoder measures distance, speed and power of the wire assuming it's perpendicular to the surface. If you pull/push the wire with an inclination, data will not be accurate and the wire can be damaged. CHAPTER 5. TESTS 31 Figure 5.8: Magnets on a metal surface 5.3.2 Concepts This manual brie y describes some concepts. Understanding them is important to use the software appropriately. 5.3.2.1 Database Chronojump stores data in one database le. Thus, instead of collecting the information in individual les for each session, most of the information is organized in a single le to facilitate the study of relationships between: sessions subjects exercises repetitions All modi cations in session, subjects and exercises, will be updated at any time in the database. So there isn't need to save the information periodically. If rare case, the program crash, you wouldn't lose any data except sometimes the exercise that is being performed at the time. 5.3.2.2 Sessions The sessions represent situations where the coach or evaluator gathers subjects for a series of tests. Every time you gather a group of athletes to be tested in a short space of time (usually one day), you should create a new session. Although the subjects to assess can be the same as in other session, you should create a new one and load them from the other session. In this way, you can make comparisons between data over time. CHAPTER 5. TESTS 32 Figure 5.9: Wire handle 5.3.2.3 subjects All individuals able to perform the tests are known as subjects. It's strongly recommended to create one person only once in order to study the evolution over time. In following sessions the person can be loaded. 5.3.2.4 Exercices Every time you want to measure, you perform an exercise. Exercise has a name (e.g. Bench press), an extra weight (e.g. 40Kg), type of contraction (e.g. concentric), laterality (e.g. both limbs), recording time (e.g. 45s) and others. 5.3.2.5 Sets (formerly signals) When the person does the exercise, encoder generates a lot of data and sends it to the computer. Exercise duration is de ned by the user who manages the software, but can be shortened if wanted. All the data received is called a set. This set is saved automatically when capture ends. The set is meaningless, it doesn't have any information on how many repetitions of the movement has been done by the person who executed the exercise. 5.3.2.6 Repetitions (formerly curves) When set is analysed, a number of repetitions are found. This repetitions have the mechanical data wanted by the evaluator: start, duration, speed, force, power. The repetitions are detected by the software automatically following user criteria.

TESTS 33 Figure 5.10: Wrong use 5.3.3 Using the encoder 5.3.3.1 Chronojump main windows Figure 5.12: Main window A) Starting on the top left of main window, there's a menu bar with session options and help. You should start your work creating a new session or loading an existing one. CHAPTER 5. TESTS 34 Figure 5.11: Measure B) Under the menu bar there's Chronopic information: number of Chronopics connected and the button to manage them. Chronopic is the microntroller used on Chronojump project to measure from external devices like a contact platform, photocells or the encoder. Use the Chronopic button to tell the software how Chronopic is connected. C) The rest of the left part of the screen is related to subjects. On the top you can create new subjects or load from another session. Below you can select the current person and nally, at the bottom you can edit the person, see all it's tests and delete it. D) The centre-right part of the screen is for managing the tests (or exercises). At the top there are two tabs: contacts and encoder. Select the encoder tab. 5.3.3.2 Connecting encoder 5.3.3.2.1 Chronopic windows In order to connect the encoder, click on the Chronopic button (B, in the above image) and Chronopic window will be opened. On this new window select Encoder and the port where Chronopic is connected. If you have any problem press the help button in that window, it has little and useful information. After Chronopic port has been selected, just close the window. 5.3.3.2.2 Encoder con guration The next step is the selection of the type of encoder, how it is atached to the machine and the type of machine used in the exercise. Figura 5.13: Encoder selection CHAPTER 5. TESTS 35 Clicking on the Select encoder button a new window with selfexplanatory images will open. Each type of encoder has a diferent set of con gurations. Clicking on the arrow buttons will change the con guration for this type of encoder There are three types of encoder: Linear. Rotary friction. Rotary axis. Some con gurations need additional parameters as angle, diameter or inertia momentum. Videotutorial: Capturing on an inclined plane machine https://youtu.be/s-8Zel1RtGs 5.3.3.2.3 Inertial machines con guration The characteristics of the inertial machines make nec- essary to enter a set of extra parameters that are being descrived below: Figura 5.14: Inertial machines parameters There's three types of inertial con guration 1. Machines where the subject works against gravity, or in a vertical movement. Example: squat. 2. Machines where the subject works in a horizontal movement. Example: lateral displacement. 3. Machines that have a set of pulleys thet makes the movement of the machine to be a multiple or a fraction of the movement of the subject with the objective of doubling the resistance oered by the machine. Below are descrived the needed parameters: Number of anchorages: Some models of inertial machines have more than one anchorage allowing to change the mean diameter where the rope is wrapped. Selecting the number of anchorages will add or supress the options to enter the diameter of each one. CHAPTER 5. TESTS 36 Inertia momentum: This is a parameter that depends on each machine and is reered to the machine without any extra load. Chronojump implements a system to calculate the inertia momentum that allows to con g an encoder in almost all type of inertial machines. Follow the instructions in section to calcuate the inertia momentum of your machine con guration. Mass of each extra load: If the inertial machine allows to add extra loads to augment the inertia momentum, Chronojump will calcule it from the mass of eache one of this loads. This way, you have to enter the mass o only one load. Distance center-load: It is the distance between the center of the extra load and the axis of the inertial machine. Force multiplier factor: This parameter especi es the con guration of the pulleys set that allows the resistance of the machine to be a multiple or a fraction of the force that the machine would oer without the pulleys set. 5.3.3.2.4 Calculation of the inertia momentum The rs part of this section will explain how to calculate the inertia momentum (IM) of the disk in an inertial machine. The calculus of the IM of a disk with attached weights will be discussed in the second part. In the following link you can see a video of the process. Calculing inertia momentum video Inertia momentum of the disk To calculate the IM of the bare disk without weights we will use a reference weight. Remember, although we will use an attached to the disk weight, the results given by Chronojump in this part of the process refers only to the disk without any weight. 1. Put the machine in a any position that makes the disk rests in a vertical plane. 2. Attach a known weight to known distance from the center of the disk. This way the disk will be unbalanced and after lifting and living the weight it will start to oscilate like a pendulus. 3. In chrono jump software, with the encoder connected go to Select encoder. Figure 5.16: Select encoder button 4. Choose type of encoder you will use, and select the Inertial machine option. 5. In this windows you will be asked for the diameter where the rope is wrapped and the IM of the machine. Note that in conical machines this diameter changes continuously as the disk is spinning. We recommend you to use the mean diameter of the part of the cone where the rope is wrapping at. CHAPTER 5. TESTS 37 Figure 5.15: Reference weight Figure 5.17: Parameters of the inertial machine CHAPTER 5. TESTS 38 6. As you want to know the IM, click on Calculate IM 7. Enter the weight (in grams) of the reference load and the distance (in centimeters) to the center of the disk. Figure 5.18: Parameters for calculating the IM 8. Pull the weight to approximately 90 degrees position and leave it. The disk should start oscil ating. 9. Quickly, click on the capture button. You will see the signal sent by the encoder. Chrnonojump will detect when the machine stops moving and will return the calculated IM. Figure 5.19: Capturing the oscilation CHAPTER 5. TESTS Inertia momentum of the disk with attached weights. 39 In the encoder con guration you should enter the distance from the center of the extra loads to the axis of the disk as well as the weight of the extra weights. This way in the exercise capture windows you will be asked for the extra weights that are attached to the disk as shown in the gure below. Figure 5.20: Exercise capturing with inertial con guration Below the extra loads selection box the total inertial momentum is shown in Kg*cm² Chronojump uses the next formulae: Iw = M ∗ d2 Where: Iw is the Inertia momentum that each weigth will add to the system. M is the mass of the weight. d2 is the square of the distance from the center of the disk to the center of the weight. And the inertia momentum of the disk with the attatched weights I = Id + n ∗ Iw Where: I is the total inertia momentum. This is the value you must enter in the chronojump software. Id n is the inertia momentum of the disk calculated in the rst part of this section. is the number of weights added to the disk. - is the inertia momentum of each weight calculated above 5.3.3.3 Encoder capture tab At this tab you can see six areas: CHAPTER 5. TESTS 40 Figure 5.21: Capture tab 5.3.3.3.1 Exercise At exercise area there's the exercise name, information of that exercise and a button to create a new exercise. Clicking at the information or at the new exercise creation you will notice there's a selector called Displaced body weight (%). This selector is important to measure the force and power, because 100% of body weight is displaced during a jump, but 0% of body weight is displaced in a bench press. Extra weight selector is used to input how many Kg are moved (weight bearing is not considered). Summarizing, weight displacement is calculated like this: W eightDispacement = P ersonW eight ∗ DisplacedBodyW eight + ExtraW eight 100 The exercise area includes also the contraction type (eccentric-concentric or concentric), the laterality, the recording time selected, the minimal height, the feedback bell 5.3.3.3.2 Aquire one can be loaded In the acquire area a new set can be captured and the recalculate button. or a previusly captured . Important!: When using inertial machiens, remember always start with the rope fully unwrapped when you press the capture button. I you don't do that, you will see that half of the repetitions have a much smaller range of movement than the other half. Right execution With the Options button Wrong execution the following parameters of the capture or loaded set can be adjusted: CHAPTER 5. TESTS 41 Figure 5.22: Capture options Recording time. How long Chronojump will be capturing the set resulting of the exercise End at n inactivity seconds. If the encoder don't receive any movement in the speci ed time Chronojump will end the capuring process. Minimal height is the minimum range of centimetres that a repetition has. E.g. In a bench press, when person lifts the bar fom r the rst time before starting exercise (weight was in the support), this is not considered a repetition because it's range of movement is lower than Minimal height de ned.

Figure 5.23: Sound feedback options CHAPTER 5. TESTS The load button 42 of this frame allows to load a set, save set again with a comment (just write comment in the area and press update), or delete the set. The load set window is used also to manage all the sets of current person. Right click on it to change the person who performed the exercise, add a comment or delete any set of a given person. Videoturotial: Edit set https://youtu.be/ UiZJKbU4OSg Recalculate can be used after capturing or loading. When user detects that some parameter has not been set correctly and wants to perform calculations of the set again, user can change the selector and press recalculate . E.g. 40 seconds squat has been done and the extra weight introduced was 40Kg but user forgot to add the weight of the lift bar. After capture, user can change 40Kg to 55Kg and then press recalculate in order to have the force and power calculated correctly. 5.3.3.3.3 Camera record At the right of the exercise frame there is a check box where a web cam can be activated. If it's active it will be used on encoder capturing. The resulting video will be attached to the encoder set and can be watched using a button on set frame. 5.3.3.3.4 set frame During the capture this frame will show the set sent by the encoder. Once nished Chronojump will calculate all the repetitions and show them in the same frame with some basic graphic information. 5.3.3.3.5 repetitions frame Once set is loaded, captured or recalculated, Chronojump will nd repetitions and write their data on a table. Here you can delete a repetition, save the selected repetition, save all or export them to an spreadsheet software. Most users will save only a repetition, or delete a repetition and the press save all. This repetitions can be analysed at the Encoder analyse tab. Figure 5.24: Saving and deleting repetitions To save or delete a repetition just click on the checkbox Saved of the repetition you want to save or delete. In excentric-concentric mode, saving a excentreic (concentric) repetition will also save the corresponding concentric (excentric) repetition of the exercise. 5.3.3.3.6 Bars frame The bars frame shows, during the exercise, the main variable in real time. This way the athlete can have an instant feedback of every execution of the exersice. The descending white line in the bar indicates an excentric repetition. An ascending line, a concentric. The saved repetitions apears with a framed number below. CHAPTER 5. TESTS 43 Figure 5.25: Power bars 5.3.3.4 Encoder analyze tab Figure 5.26: Analyze tab Regarding the data, two things can be analysed: current set repetitions (the set in the capture tab) or user . When User repetitions is marked, then using the Select button, it can be discriminated the active repetitions and the not-active. The analysis will cover only the active repetitions. Also the User repetitions allow to make comparisons between subjects (to compare the dierent subjects in this session), or between sessions (to compare the evolution of a person during dierent sessions). There are ve modes of analysis: CHAPTER 5. TESTS 44 Individual / Current Set Individual / Current session Individual / All sessions Groupal / Current session : Analysis of all repetitions of the current set. : Analysis of the saved and selected repetitions. : Analysis of all repetitions saved in the selected sessions. : Analysis of current session and selected subjects. Within each mode there's various types of analysis: Power bars : Shows power, peak power, time needed to arrive to peak power and range of movement. Cross variables : to show relationships between variables like Power / Load. Includes the 1RM calculation. Cross variables is the only analysis that can be done on compare mode. Videotutorial: Power vs Load curve 1RM : https://youtu.be/mynNxYELja4 It allows to make dierent calculations of the maximum repetitions that can be performed with dierent loads. Videotutorial: Chronojump tutorials: Estimate nRM indirectly https://youtu.be/sd40bI2UQ9c Side compare : to see a graph of the mechanical variables of dierent repetitions all with the same axis. Single repetition : to see a graph of the mechanical variables of a repetition. Neuromuscular pro le : to see the neuromuscular pro le of the three best jumps of a set of six. At least six jumping repetitions are needed to performe that kind of analysis. The analysis starts when user click in Analyse. After a while, a graph and a table will appear, both can be saved using each save button in the lower right. 5.3.4 Encoder settings and preferences At preferences there are some options that are more advanced and are not changed frequently. Clicking at Session / Preferences you will see ve tabs, third one is related to encoder. If you want to do calculations of mechanical parameters only in the propulsive phase just ensure the parameter propulsive is active. The meaning is the following: In a fast concentric movement where there's little weight displaced, the brake action of the person in the nal phase of the movement will not be used in the calculations. Nowadays most coaches prefer this option active because they noticed that the comparison of mean power between a light weight and a heavy weight exercise is not fair because the brake phase in the light weight exercise is related to negative force and the power values get very low. Then, if propulsive phase is active, only this is used, and not the brake phase. On Save repetitions automatically on capture can be selected what repetition must be saved when perfoming a new exercise. By default the repetitions with the best mean power will be saved, but it can be changed to Save all the repetitions or Do not save any repetition of the exercise. The next options are related to smoothing of the capture and we recommend to leave them untouched. In the 1RM prediction, the method to get the linear regression can be selected. The exponent in the weight means that the larger is the mass of the point used the larger is the weight used for the regression. The function of the weight can be zero (non wighted), one (linear), two (quadratic) or three (cubic). CHAPTER 5. TESTS 45 5.3.5 Examples of encoder use At the Gym: 1. On the oor, at the side of the weight bar, put a gym weight (not made by rubber) and encoder on the top of it (attached with the magnets). 2. The plastic hook is attached to weight bar securely, and to encoder. 3.

TESTS 46 Figure 5.27: Example of encoder use 5.4 Other tests 5.4.1 Reaction time In order to detect reaction time of the person, there's a need of an assistant, because Chronojump and Chronopic are still unable to produce random signals that can be measured accurately. 5.4.1.1 Protocol Assistant will produce contact in a contact device: push-button, platform, photocell, ... and at any moment (when athlete is prepared), assitant will release the contact and instantly the Chronopic green led will light. At this moment, the athelete will produce contact in another contact device and green light will be o. The reaction time registered will be the time between light starts glowing and athelete produces contact. It's important that athlete doesn't see or hear the assistant. 5.4.1.2 Executing reaction time To execute a reaction time, have the assitant producing contact in device, click on Execute reaction time and follow the protocol described above. If Chronopic has not been connected and activated from Chronopic window, a reaction time will be simulated. In the other hand, if Chronopic is connected, real reaction time will be done. CHAPTER 5. TESTS 47 5.4.1.3 Reaction times view Reaction times are shown on the reaction time tab. Tests are associated with the athletes. The shown order of the tests of each jumper is chronological so, the last test appears at the end of the list You can use the magnifying glass button (or press z ) to facilitate the view of the tests. 5.4.1.4 Reaction times edition You can add comments to a reaction time or change the person (if you forgot to change the current person previously) If you select the desired test and click on the Edit button on the selected test, you can also nd it on the menu, or by pressing the button e. 5.4.1.5 Reaction times delete To delete a reaction time, select it and click the Delete selected reaction time button. alent in the menu or press d (delete). Its equiv- By deleting the test you will be asked to con rm it if the delete con rmation option is activated in the Preferences menu (more information in section 9.1 en la página 73). 5.4.2 Pulses (Simple rhythms) A simple rhythm or pulse can be measured on the Pulse tab. On the other hand, if a comple rhythm has to be measured, use a MultiChronopic as described at 5.4.3 en la página siguiente. There are two kind of tests: Free Person tries to be regular on the freely selected pulse. Evaluator will decide te moment where the test end. Custom Person has to follow a prede ned tempo. If desired, the total duration of the test can be de ned. Tempo can be de ned in one of this ways: seconds how many seconds pass between pulsations ppm how many pulsations per minute Both methods are interrelated, if eg. seconds value is changed, then ppm changes. As an example, 0.5 seconds are 120 ppm. Evaluator will decide what is more suitable. 5.4.2.1 Ejecución de pulsos Desde la pestaña de pulso y con el ayudante sin tocar el pulsador o plataforma, haga clic en el botón: Libre, o en el botón Personalizado. En caso que no este conectado el Chronopic, el programa simulará un pulso. En la ventana emergente se mostrará la progresión del test, que podrá ser detenido haciendo clic en el botón Terminar o cancelado con Cancelar. CHAPTER 5. TESTS 48 5.4.2.2 Pulses view Puede usar los botones de lupa (o la tecla z ) para facilitar la visualización de los tests. Pulses are shown on the pulses tab. Tests are associated with the athletes.

Its equivalent in the menu or press d (delete). By deleting the test you will be asked to con rm it if the delete con rmation option is activated in the Preferences menu (more information in section 9.1 en la página 73). 5.4.3 Multi Chronopic Multi Chronopic allows any type of test that uses two, three or four independent measurements Chronopics. Remember that for the other tests it's possible to connect multiple devices to a sin- gle Chronopic, but it's understood that that always have to be in touch in one or both of them. Unlike previous tests, Multi Chronopic allows the use of several Chronopics, each connected to one or more detection devices, so that contact can be more than Chronopic at a time. Their operating depends on the program user, but here are some examples: 1. Static Test running on two platforms: the aim is to assess the tempo of tread of the left and right foot. It's required that each Chronopic is connected and independent since the sportsman is often stepping on both platforms 2. The study of the contact times in a volleyball jump: One foot in each platform, then both take o at the same time. To know various times is needed 2 Chronopics platforms and 2 independents ones. 3. Plate Tapping with extra coordinative action: Construction of a device type detection Plate Tapping, where the tester must touch either side as quickly as possible with a single hand. Connect a conductive part to any side and to one Chronopic to record the dierent times. Moreover, if the subject should do something with his foot every 3 contacts we can locate a contact platform on the oor and connect it to a second Chronopic. 4. Two, three or four athletes do a round trip timed race on a track: there is placed a platform at the beginning and nal of each lane. A Chronopic will be connected to the beginning and end platform because a person can't be at both at once. Thus, if there are 4 subjects it will be 4 lanes, 4 Chronopic and 8 platforms. We will be able to measure the times and speeds of each 4 independently. CHAPTER 5. TESTS 49 5.4.3.1 Synchronization Some of these tests require a synchronization to intend that the various Chronopics start at the same time. However, in others the synchronization is not required. In the rst three examples cited above, synchronization is required so there is no error in the comparison of time between a tread and the other (example 1 and 2) or from contact with the tapping and the tread on the ground (Example 3). This sync can be selected from a check box and carried out by making contact with several devices at once, or by touching the Test button http://forum.chronojump.org of Chronopics. In the Chronojump Forum is described a method for the construction of a professional sync device. The sync in the fourth example requires discussion. If the subjects leave when they want and the aim is to record only the time between contact and the next synchronization is not required. On the other hand, sync is needed if we use the signal of an external evaluator, and when we expect to know the time between the signal (of any contact) and the rst contact each athlete. 5.4.3.2 Erase rst time In some tests, the time of the rst contact until the rst change of state is not relevant. Perhaps, the subject can begin whenever he wants. If you want to compare the subject's ability to follow an independent press with both hands (two Chronopics). The time registered since the start until the rst contact is not relevant and should be removed to avoid contaminating averages. 5.4.3.3 Port con guration Obviously, it's imperative to set up two Chronopic in the window Chronopic: Tools / Chronopic, to run the tests proposed. 5.4.3.4 Multi Chronopic results view In the results window, we can observe dierent columns, if two Chronopic have been used: Time: The time from the beginning of the test CP1 and CP2 State: Information on which change has occur in each Chronopic (if any) at the time point indicated in the previous column. CP1 and CP2 Change: Time elapsed since the last change of state in each Chronopic. IN-IN CP1 and CP2: Time elapsed since each Chronopic changed the state IN until he returned to the same state. OUT-OUT CP1 and CP2: Time elapsed since each Chronopic changed the state OUT until he returned to the same state. Description: Comments on the particular test run. In the example in Figure 5.28 it shows a Multi Chronopic test duration: 0.928 seconds in which there are 10 state changes. Multi Chronopic 1, 2, 10n is called so because is used 2 Chronopics (Chronopics 1 and 2), and has 10 changes. If we observe the change number 5 it occurs at 0.539 seconds. This represents a change of status Out Chronopic 1 (no contact) within a (contact). As indicated in CP1 CHAPTER 5. TESTS 50 Figure 5.28: Multi Chronopic screenshot. Change, 0.225 seconds have elapsed since the Chronopic was in its previous state (Outside) and 0.353 seconds since this was Chronopic (Inside) as re ected in IN-IN CP1. Also note that the column IN-IN and OUT-OUT have average values and standard deviation (SD). Just as the other tests, the tests are associated with the performers. The order of presentation of each test in each performer is chronological so the latter carried out by a subject appears at the bottom of the list of the tests. You can use the magnifying glass button (or press z ) to facilitate the visualization of the tests. 5.4.3.5 Multi Chronopic test edition and erase You can add comments to a test or change the performer (if you forgot to change the current subject previously) by selecting the desired test and click on the Edit Multi Chronopic button. It can also be done in the menu or press e. To delete a Multi Chronopic test, select it and click the Delete Multi Chronopic button selected. Its equivalent in the menu or press d (delete). By deleting the test you will be asked to con rm it if the delete con rmation option is activated in the Preferences menu (more information in section 9.1 en la página 73). 5.4.3.6 Run analysis In addition to the examples given we have to include a test to analyze the run produced by Josep Maria Padullés as part of his doctoral thesis. As sense devices it's used two photocells barriers and a track with contacts platforms. CHAPTER 5. TESTS The two photocells are connected to the 51 rst Chronopic to know the time between them. The program evaluator will indicate the distance between them and thus it can be known the average speed. The track of platforms will be connected to the second Chronopic, which will give us the contact time and ight time. In this case the synchronization between Chronopics or deleted the rst time is not required. From the data obtained by both Chronopics, you will get the average speed of the race, and the following data for each of the steps: Contact times Flight Times Total Time Frequency Amplitude Height Takeo angle You can see an example in Figure 5.29. Note that the execution button Running Analysis will be activated when the distance between the photocells and the two Chronopics are connected. Figure 5.29: Multi Chronopic screenshot with Run Analysis results. Chapter 6 Statistics and graphics of jumps and races Chronojump has multiple indices to study the tests proposed. Unlike general spreadsheets purpose, the provision of statistical and graphics has been designed speci cally to measure jumps and running. Figure 6.1 shows the statistics window that appears when you click on Tools / Statistics. Figure 6.1: Chronojump statistics window. The current version only provides statistical Chronojump concerning to jumps. Future versions will also include other statistical tests. If you have graphics and other statistical tests, we recommend that you export the worksheet data as described in Section 7.2. 52 CHAPTER 6. STATISTICS AND GRAPHICS OF JUMPS AND RACES 53 6.1 Statistic type, subtype and applications Each statistic can be classi ed by type, among which are: Simple jumps which oers several ways to analyze simple jumps without contact time. Simple jumps with contact time which oers various ways to analyze simple jumps with contact time. Reactive jumps which presents several ways to analyze repetitive jumps. 6.1.1 Simple jumps The simple hop statistical show various ways to analyze simple jumps without contact time, which can be classi ed into several subtypes: No index Force-velocity Elasticity rate (IE) Use of arms index (IUB) Power peak of Lewis, Harman, Sayers (2), Shetty, Canavan, Lara (5) 6.1.1.1 No index Statistical simple jump that shows all the jumps or a particular type as selected on the application eld. 6.1.1.2 Force-velocity Statistical simple jump that shows the force-velocity relationship according to the formula FV = SJ+(100% SJ ∗ 100 SJ jumps with 100% extra charge to the body weight, and SJ with no additional charge. 6.1.1.3 Elasticity index Statistical simple jump that shows the elasticity index formula IE = (CM J−SJ) SJ ∗ 100 between SJ and CMJ jumps. 6.1.1.4 Use of arms index Statistical simple jump that shows the rate of the use of arms from the formula IU B = between CMJ and ABK jumps. (ABK−CM J) CM J ∗ 100 CHAPTER 6. STATISTICS AND GRAPHICS OF JUMPS AND RACES 54 6.1.1.5 Substraction between tests Statistical tha shows the relative dierence between two tests. %dif = (test1−test2) test2 ∗ 100 6.1.1.6 Peak power Figure 6.2 is the ratio of power peak of the individual authors and their formulas. In the future, is expected to include expanded documentation for each formula and literature. Figure 6.2: Statistics of simple jumps. 6.1.2 Contact time jumps The most important in this type of jump is the relationship between ight time and contact time. In many sports it's necessary to generate a high power (re ected in the ight time) in a short time (represented by the contact time). We present two indexes to study the relation: Dj Index Index Q The application eld in both cases refers to the type of jump that is applied to the statistic. CHAPTER 6. STATISTICS AND GRAPHICS OF JUMPS AND RACES 55 6.1.2.1 Dj index Study of the relationship between time of ight / time of contact in a single jump from the formula DJindex = T F −T C TC ∗ 100 6.1.2.2 QIndex Study of the relationship between time of ight / time of contact in a single jump from the formula QIndex = TF TC 6.1.3 Repetitive jump In the repetition of a jump test speci ed by a number of jumps, time, or unlimited ends when the coach or athlete decides it. It represents the evolution of ight time with respect to the contact time in the dierent jumps. With this objective are the following statistics: Average index Power (Bosco) Evolution Mean and standard deviation using RjIndex Mean and standard deviation using QIndex In all cases the application eld refers to the type of jump that is applied to the statistic. 6.1.3.1 Average index Study of the relationship of ight time / contact time in the repetitive jump according to the formula AverageIndex = T F mean−T Cmean T Cmean ∗ 100 6.1.3.2 Power (Bosco) Study of the relationship of ight time / contact time in the repetitive jump according to the formula P ower = 9.812 ∗T F mean∗jumps∗totalT ime 4∗jumps∗(totalT ime−T F mean∗jumps) 6.1.3.3 Evolution Study of the relationship of ight time / contact time over the repetitive jump according to the evolution of the formula Evolution = TF TC ∗ 100 for each twitching. Sometimes some athletes do a jump with a very good TF / TC because of the execution of a low one before or afterwards. For this reason it has arranged the option to make the best 'n' row to get a selection of the best range following this index. To the right of this option you can nd the amount of jumps you want to study. If you select a value of 1 then the best jump will be highlighted. CHAPTER 6. STATISTICS AND GRAPHICS OF JUMPS AND RACES 56 6.1.3.4 Mean and standard deviation using RjIndex Study Index RjIndex = T F −T C TC ∗ 100 for each of the jumps of the repetitive jump test it's shown the average and standard deviation obtained. 6.1.3.5 Mean and standard deviation using QIndex Study Index Qindex = TF TC ∗ 100 for each of the jumps of the repetitive jump test it's shown the average and standard deviation obtained. 6.2 Multisession statistics All statistical presented except the Evolution in the repetitive jumps can be used for the comparison of dierent jumps or subjects in several sessions. This will submit a column for each selected session and facilitates comparison between the dierent values shown. It also includes the average and standard deviation of each row displayed. To access to the statistics multisession click on session / selected and select the sessions you want to use in the window that appears when you click on Select. You can select as many sessions as desired and is not required to display the current session between them. 6.3 Selection of the jumps to be shown There are four selection modes for the jumps shown as a condition in the generation of statistical expectation: All shows the results of the selected statistics. Limit n Average shows the rst n selected statistical results. shows the average of each jumper in the selected statistic. Max /s of the jumper show n maximum values of each jumper in the selected statistic. Most of the statistics oers the four options. Those omitted is because is not a purpose generate them. 6.4 Other settings Other related action buttons presented below. 6.4.1 Statistics formulation All statistics have a statement that is automatically created based on the selections made by the user in the statistics window. The statement can help you understand the statistics. CHAPTER 6. STATISTICS AND GRAPHICS OF JUMPS AND RACES 57 6.4.2 Genus distinction It presents the option of distinguish between genders for the presentation of the results. Selecting this option you can have a dual behavior: When the result rows correspond to the statistical index or jumping, gender selection will lead automatically to the creation of a row for each of them. When the result rows of statistical correspond to the subjects, it will appear a letter at the end of the subject to indicate the gender. This button can help intra and inter genus comparisons. 6.4.3 Automatic actualization The statistics window Chronojump is designed so each change in the database (new jump, subject rename, delete, jump, change jumper who has made a jump ...) is updated directly. 6.5 Marked rows In the rst column of each row you will nd a small box that allows you to select whether or not a row is taken into account for the graphs and reports generated with Chronojump. The rst row contains a checkbox that lets you quickly select and deselect all values. Furthermore, we show a selection box at the left bottom that allows you to expedite the selection of rows based on dierent criteria. For more information on charts and reports in paragraphs check 6.6 and 7.1 respectively. 6.6 Graphic creation Chronojump can create any graphics of any of the data shown in the statistics window. To do this simply click on the Graph button that appears in the statistics window. In the gures 6.3, 6.4, 6.5, 6.6 there are some examples of graphics generated. CHAPTER 6.

STATISTICS AND GRAPHICS OF JUMPS AND RACES Figure 6.6: Graph dotchart a subset of the above values. 61 Chapter 7 Report and export in jumps and races We propose two ways to work with raw data using Chronojump. First of all: Reporting, with the utility to create a web page with the content of the session as well as selected statistics and graphs. After this: Export to spreadsheet data. Export to the tests program analysis with general purpose spreadsheet (spreadsheet). 7.1 Report generation Reporting on the program Chronojump is the best way to collect information, statistics and graphs, in one session. This information can be in one study or with the comparison of various. Clicking on View report window , the gure shown is Figure 7.1. The users have the ability to create a report in web format (HTML) which can include session data, the subjects who participated and the tests chosen. Furthermore, using the Add to report button is allowed to prepare each of the statistics displayed. Do the apparition in the report generated and the customization that was chosen by the user in the statistical window. The user can also organize each of the statistics to do the nal report. Clicking on Make Report, you can choose the lename images/to save the HTML document. Also, you can generate a folder that will include all necessary images and styles to display the page properly. To print the report, we strongly recommend using the free browser Mozilla Firefox. In Figure 7.2 you can see a photo of a report. 7.2 Export to a spreadsheet Clicking on Session / Export session to CSV to create a CSV le format (Comma Separated the Values) which can be easily imported into any spreadsheet program. This le contains the records of all the tests produced, but it shall not include statistical or graphics. To export to CSV we chose the semicolon character (instead of comma character) to separate the dierent columns of data. Remember to indicate it when you import the CSV le in the spreadsheet. 62 CHAPTER 7. REPORT AND EXPORT IN JUMPS AND RACES Figure 7.1: Example of report window preparation. 63 CHAPTER 7. REPORT AND EXPORT IN JUMPS AND RACES Figure 7.2: Example of a website report. 64 Chapter 8 Share Data Server Chronojump has a server to share data between users on Internet. The server will obtain valuable data from the cross of many variables. For this, the users may share the data Chronojump. We believe in the good quality and usability of the technical characteristics of the server. Chronojump dispone de un servidor en Internet para compartir datos entre los usuarios. El servidor permitirá obtener datos valiosos a partir del cruce de muchas variables, pero para ello es necesario que exista predisposición por parte de los usuarios de Chronojump para compartir los datos. Creemos que las características técnicas del servidor y su usabilidad son óptimas. 8.1 Share and use the data The data that can be shared are the tests, subjects and sessions of each evaluator at any time. The evaluator may upload to the server any session, dismissing those athletes and tests that he doesn't want to share. Before upload the data to the server, check if they have completed the necessary data from each of the athletes as well as the data required from the evaluator. 8.2 Data quality. Accredited assessors and reliable data In order to get a lot of data, without sacri cing the quality, there are two types of data in terms of reliability: The general data that can be upload from anyone with the Chronojump technology. This will soon be available for many data that belongs to this category. The reliable data requires the accreditation of the evaluator and the justi cation of the session data. This deals with three dierent pro les of the evaluator: Evaluator-trainer pro le: person related to the eld of training. Evaluator-researcher pro le: person related to the academic eld. Mixed pro le: person involved in the two areas mentioned above. The process of accreditation of the assessors has not yet begun, so all assessors are currently uncredited and the data shared corresponds to general data. In the future, the new credited evaluators may wish to upload their data to the reliable data, even if this data has been uploaded without the accreditation. The accreditation is in charge of the Research Group: Salut, Activitat Física i Esport at the Blanquerna Faculty (Universitat Ramon Llull). 65 CHAPTER 8. SHARE DATA SERVER 66 8.3 Server functions Server functions can be located in the main menu, Tools / Server. Below its described each of them. 8.3.1 Check connection Allows connecting to the server. If not possible, it may be because the server is temporarily inoperative, your computer is not connected to Internet, or your Internet connection has limit on some types of connection. 8.3.2 Evaluators data This feature allows the evaluator to ll in a sheet which will be linked to the tests, subjects and sessions that will be shared. The personal information will be hidden. It's necessary to provide evaluation data for the following reasons: It's essential for uploading data. Allows knowing the nationalities, ages, equipment, evaluators. . . If problems occur with some data, the administrators can contact via mail to the server of the evaluator. As discussed in Section 8.2, currently the accreditation is not required, so the sheet that has to be lled is very short. See Figures 8.1, 8.2 and 8.3. to check the for data window for the evaluators. Figure 8.1: Details of the evaluator, Tab 1. 8.3.3 Upload or update session to server This is the most important function to share data. When the evaluator click on Tools / Server / upload (or update) session to server, he must follow this steps: 1. First, the evaluator will be asked to verify the data as described in paragraph 8.3.2, CHAPTER 8. SHARE DATA SERVER 67 Figure 8.2: Details of the evaluator, Tab 2. Figure 8.3: Details of the evaluator, Tab 3. 2. then the evaluator will be asked if he wants to discard some of the subjects of the session (see Figure 8.4), 3. then he will be asked for the con rmation, 4. nally it shows a progress window of data to be incorporated into the server. At any time the evaluator can re-upload the session to the server (update). The data that has already been uploaded will not be included again, but it wills so, the data created the last time. The tests that have been simulated (not obtained from Chronopic) will be uploaded to the server. 8.3.4 Query the server It has been created a window that allows average of the simple jumps, reactive jumps and simple runs. To access to it click on Tools / Server / Query. The query is performed clicking on the test selectors and the subject selectors. Below, we can observe the selectors of the query. Some of them are mandatory, while the most can be selected on Any to indicate that this variable should not aect the result. CHAPTER 8. SHARE DATA SERVER 68 Figure 8.4: Include / Discard subject to the server. 8.3.4.1 Test selector Here are the three selectors and possible values: Test type: Test: simple jump test, reactive jump or simple run. correspond to the type of test described above. Variable: the average obtained will be dierent depending on the test selected: For a simple jump test without contact time the only variable is the ight time. For a single jump with contact time, the variables are: time of ight, contact time, Index DJ (see 6.1.2.1), Index Q (see 6.1.2.2). For a reactive jump the possible variables are: Average Index (see 6.1.3.1) and Power (Bosco) (see 6.1.3.2). For the running the only variable is the time. 8.3.4.2 Selectors on the subject The selectors are: Sex Age: Refers to the age of the subject at the time the test is made. To calculate the age of the subject it's used the date of the birth. Country Sport: Sometimes subdivided into specialty. Level: Divided into: [0] sedentary or occasional practitioner, [1] regular practice, [2] competition; [3] elite. CHAPTER 8. SHARE DATA SERVER 69 8.3.4.3 Evaluator selector Any data from a particular evaluator can be chosen. This option may be interesting even for yourself because this way is possible to quickly gather information from all the jumps that have been evaluated. 8.3.4.4 Query results When you click the search button, after a few seconds the server will indicate how many results have been found and which is the average. It is recommended to conduct general searches because the server has been created recently. As an example of search, try with simple jumps (Free) with most of the indicators on Any. In Figure 8.5 is an example of consultation. Figure 8.5: Query the server. 8.3.5 Server main statistics It has been programmed a window to get a snapshot of the existing data on the server. It shows the number of evaluators, as well as the subjects and the various type tests. Also indicated which data has been uploaded by the user who runs the program. You can access to this window by clicking on Tools / Server / Statistics. CHAPTER 8. SHARE DATA SERVER 70 8.4 Web statistics The web page http://www.chronojump.org/server.html ables updated from the server. shows the results from the crossing vari- These charts are updated every time new data is included (usually automatically at night). The aim is to create constantly a set of charts that provide relevant information to anyone interested, even without using Chronojump. In Figures 8.6, 8.7, and 8.8 it's possible to check some examples of graphics that are obtained on the web server. Figure 8.6: Statistics on the web server. Population graphic description. CHAPTER 8. SHARE DATA SERVER 71 Figure 8.7: Statistics on the web server. Boxplot ight time depending on the type of jump and gender. 8.5 Jumps privacy and con dentiality The names and dates of birth of the athletes and the evaluators will never be shown. Even when uploading the data, the names of the subjects are not sent (because is not required). The date of birth will be included to calculate the age, but it will never be displayed. The comments the evaluator add to the session, subject or test are neither provided. CHAPTER 8. SHARE DATA SERVER 72 Figure 8.8: Statistics on the web server. Graph relates ight time, practical level, type of jump and gender. Chapter 9 Preferences of Chronojump The preferences window Session / Preferences, is divided into seven tabs Database, Jumps, Runs, Encoder, Camera, Language and Other. 9.1 Using Chronojump on more than one computer Figure 9.1: Preferences. Database tab. Database tab shows where Chronojump data are, allows to open the folder, and make one copy of it in a directory of choice for the users. Maybe it shows two possible locations for the database because some Windows systems oer a place to store data while the program runs, and another when it's closed. Use this tab to have a copy of your data in order to avoid loosing your sessions, subjects and tests on a hard disk problem or if operating system is reinstalled. Also you can use this tab to have Cronojump database in more than one computer. If you want to copy the data stored in the computer A to the computer B, follow this steps: 73 CHAPTER 9. PREFERENCES OF CHRONOJUMP 74 1. On computer A: (a) Go to: Session / preferences / database (b) Select the items you want to backup (c) Click in Backup database. (d) Depending on what you have selected to copy, a le or a folder with its corresponding subfolders will be exported. A directory called chronojump will be created with all the selected data if you selected to backup the Multimedia and encoder tests. If you didn't selected to backup the Multimedia and encoder tests, a le called chronojump.db will be copied. 2. On computer B: (a) If Chronojump is not installed, do it. (b) Go to Session / preferences / database / open database folder . A le explorer window will be opened. (c) If you have valuable data on B, then you should make a copy of the chronojump.db or the Chronojump whole folder that is located two levels above in the folders hierarchy. (d) Copy the chronojump folder or the chronojump.db le from A to B. (e) Close chronojump, open again, and it's done. 9.2 Jumps Figure 9.2: Preferences. Jumps tab. Jumps tab allows to select the information columns that you want to show in the data windows and statistics window. CHAPTER 9. PREFERENCES OF CHRONOJUMP 75 9.3 Runs Figure 9.3: Preferences. Runs tab. This tab allows to con gure the behavior of Chronojump in the running tests. The rst option refers to the behavior of Chronojump in the rs contact of a race. It allows to de ne if the time starts to count when the rst contact occurs (stepping on a platform or a photocell gate) or at the moment that the contact is over (step o on a platformm or a photocell gate). The second option allows you to manage the contacts that are produced in a short time period. Example: In a race with a couple of photocell gates separated by 10m, an athlete, arriving to one of the gates cross it with the hand and after that with the body with a dierence of 20ms. In this case you could set that contacts separated in the time less than 500ms are considered as only one. CHAPTER 9. PREFERENCES OF CHRONOJUMP 76 9.4 Encoder Figure 9.4: Preferences. Encoder tab. This tab allows to con g the behavior of Chronojump in the encoder tests. The propulsive option is used for calculating for only using only the part of the movement where the acceleration is superior to gravity, in other words, when some force is applied. You can also select the options of automatic repetition save, as well as the options of the smoothing used in the calculus. About the 1RM prediction you can select whe method used to weight the statistical data depending on the load used. CHAPTER 9. PREFERENCES OF CHRONOJUMP 9.5 Camera Figure 9.5: Preferences. Camera tab. This tab allow to select the camera that will be used to take photos or videos with Chronojump 9.6 Language Figure 9.6: Preferences. Database tab. With this tab you can select the language and translation options. 77 CHAPTER 9. PREFERENCES OF CHRONOJUMP 78 9.7 Other Figure 9.7: Preferences. Database tab. Other tab has three options. First refers to the number of decimals (recommended 3). If second option is active, then a con rmation window will be shown every time that user wants to delete a test. The last action is speci c to the time that limits reactive jumps. If this option is checked, then a reactive jump limited by time will accept a jump where the person is in the air in the moment that time nishes. If is unchecked then this last jump will be rejected. Appendix A Chronopics prior to Chronopic 3 This appendix is only useful to users who own an old Chronopic (sold before March 2008).

CHRONOPICS PRIOR TO CHRONOPIC 3 80 Figure A.2: Chronopic2-Serial. A.2 Connections in Chronopics serial Chronopics serial require external power therefore it should be connected to a feeder. In addition, these Chronopics requires to be connected to the computer by a cable. If your computer has serial port, it's enough with a telephone cable serial. If it doesn't have USB port, you must convert to USB, it's required a USB-serial cable or a PCMCIA adapter or with another adapter with the same functionality. See gure A.1 for an example of Chronopic1 connection. Serial Chronopics use 4.5 to 6 volts feeder. Is possible the purchase of a conventional power supply (which is connected to a power source) or create a homemade feeder with 3 x 1.5 volts batteries. This option provides the eld tests in Chronopics serials. With old Chronopics series, the battery connection should automatically turn the light on even if the Chronopic isn't connected to any computer. This is a good test to know if the power is working. If it doesn't work, is recommended to connect the power to the Chronopic and verify that the light is on (no need of computer) If the light doesn't turn on, this mean that the failure is in the Chronopic or in the feeder. Try this again with another feeder or Chronopic to determine the origin of the failure. The feeder should be between 4.5 and 6 volts. Some feeders have two polarities, ask the seller and connect with the correct polarity. A.3 USB and serial ports Chronopic should be connected to the contact platform and the computer. PC connection is via port as shown in Table A.1. Currently, most laptops do not have a serial port, so the USB port is required by most users. Users without serial port should get a pcmcia card or similar type to add serial port to the computer. The latest and favorite choice is to get a USB-serial cable. In many cities it's di cult to nd these cables in stock if they haven't been previously requested. Another option is to buy them online. The operating system assigns names to ports, as shown in Table A.2. APPENDIX A. CHRONOPICS PRIOR TO CHRONOPIC 3 81 Figure A.3: Chronopic1. Operating system Port Name MS Windows Serial COM1 or COM2 MS Windows USB COM1, COM2, COM3, ... (seen GNU/Linux Serial GNU/Linux USB to COM27) /dev/ttyS0 or /dev/ttyS1 /dev/ttyUSB0, /dev/ttyUSB1 Table A.2: Names of each operating system port. The most common names are in bold type text. The plate-USB Chronopic2 may require a driver if Windows is not able to detect it. Windows should automatically assign a name (COM1. COM8 ..) to the USB port connection, but in many Windows installations this process is not completed therefore it's required the driver (According to the manufacturers is not necessary the cable because is automatically detected). Therefore is recommend to download a USB-serial driver: http://www.serialgear.com/wd_pl2303h-hx-x_v20019v2021.zip, or any other provided by the manufacturer or obtained by the network looking for "USB-serial driver ". A.4 Chronopic3 assembly process (initial units) Chronopic was initially distributed in two parts: the circuit and the elements that made up the box: methacrylate, screws and washers. Figure A.4 shows the assembly. Note: These instructions are only necessary for the rst step of the assembly process. The latest Chronopic versions are fabric build. APPENDIX A.
