| 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.

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.
