 The Jump Test is a method to measure lower-limb muscle power, as well as coordination of lower and upper extremities, by jumping as high as possible. Jumping height is calculated from flight time.\\ The Jump Test is a method to measure lower-limb muscle power, as well as coordination of lower and upper extremities, by jumping as high as possible.

-The gold standard for measuring countermovement jumps is with a force platform. The Chronojump was validated against a force platform in thirty recreationally active adults ((Stanton R, Doering TM, Macgregor C, Borges N, Delvecchio L. Validity of a contact mat and accelerometric system to assess countermovement jump from flight time. Measurement in physical eduation and exercise science. 2018)).\\ +The gold standard for measuring countermovement jumps is with a force platform.

 The Bland-Altman plot showed that Chronojump underestimated countermovement height by 5.46 cm. Previously it was shown that reliability was greater for participants more accustomed ot strength training. The Bland-Altman plot showed that Chronojump underestimated countermovement height by 5.46 cm.
