Reactive strength index improvement
WebReactive strength index (RSI) is the ratio between the height jumped and the ground contact time, calculated by dividing the jump height by the ground contact time. The jump height time is the time between the participant's feet leaving the timing mat or force platform and when they contacted it again. The vertical jump height in meters can be ...
