MySprint New Version Tutorial!

Power-Force-Velocity profile is an innovative, simple field test to measure the individual sprint mechanical outputs [force, velocity, power, effectiveness] of athletes. It was developed and validated by Dr Samozino and Pr Morin, and it is currently being used by elite athletes, coaches and researchers around the world.

You just need to perform a 30 m sprint according to the references system proposed in the App. For it, you only need six visible vertical markers [like thin poles] located at 5.57 m [for 5 m], 10.28 m [for 10 m], 15 m [for 15 m], 19.72 m [for 20 m], 24.43 m [for 25 m] and 29.15 m [for 30 m] meters and to record the time between markers F-v sprint profile with My Sprint. Note that you should place these markers so that you see on the camera the athlete’s chest crossing them when he/she is at 5, 10, 15, 20, 25 and 30 meters [so markers should not to be exactly at theses distances from the start lines due to parallax]. For a good validity, you should place/hold the iPhone in a tripod (in the frontal plane) in order to do a smooth rotation movement of the iPhone during the recording of the sprint at 10 m from the track [see figure in the App]. After that, you can select and click on My Sprint screen [in manual frame by frame mode] the first frame in which subjects’ right thumb leaves the ground [then click start], and subsequently, the frame in which the chest is crossing each selected markers in the video [then click on each split distance][Figure 3 in the App].

That's it! You can now click to compute the F-v profile and know your athlete's sprint mechanical outputs [force, velocity, power, effectiveness] just with your iPhone or iPad, and with an accuracy close to that of a 40-m force plate system [Samozino et al. 2015]!
