About NS Yo-Yo
The Yo-Yo test (also known as shuttle test, beep test or test of Léger) is considered to be the most accurate and reliable field test for the evaluation of athletes' VO2max. The only drawback is that, in theory, you'd have to lug around a stereo, an audio track and a specific conversion table definitely not easy to read. With NS Yo-Yo doing this test to your athletes become simple and straightforward and you can easily review, with special graphs, all the progress made over time by your team.

This is the beep test. The app itself is attractive and looks great, but does not function well for more than one individual.
