Reactive strength index norms
WebThe reactive strength index (RSI) is a measure of force and the time that is taken to develop it, by calculating the jump height divided by ground contact time during the depth jump (DJ) ( 7,17,18 ). The RSI is typically determined using a force platform or contact mat ( 8,12 ). WebReactive strength is a physical quality that encompasses the stretch-shortening cycle (SSC) and refers to the muscle’s ability to absorb, amortize (stabilize or control), and finally, …
