If you find this application useful, please give a positive review in the AppStore, so we can further improve and develop new options. The 'YO YO Endurance Test' can be used to determine the level of athletic in all sports (football, running, basketball, volleyball, cycling, tennis etc). The second value obtained on completion of the test, is the first result considering also the total time of the test. Basically the final result is given by a mathematical formula that processes the delta between the averages of the last two split times and the first two split times and thereby the athlete's ability to maintain its maximum speed for a certain period of time. More these values are low and better will be the athlete's performance. This application will track all the split time and at the end will be calculated two parameters that determine the outcome of the test. This path must be repeated for six times without any break, and get the split times every time the athlete passes on the first cone. The athlete has to run at full speed from one cone to another and then return again on the first cone. The physical capacity is evaluated quickly and easily by placing two cones spaced 20 meters each other. The 'YO YO Endurance Test' provides an important instrument for determining the level of physical efficiency of an athlete.
