Reactive strength index norms
WebReactive Strength Index (RSI), which is a depth jump with a look at height divided by ground contact time. The RSI gives a better look at the central nervous system, while the lifts look closer at the peripheral nervous system. Velocity is the simplest way to measure fatigue. If you are using VBT already, it doesn’t require anything extra. WebReactive Strength = Measure of RSI = Measure of SSC RSI is the measure of an athlete’s reactive strength RSI = Jump Height Ground Contact Time The RSI Score directly relates to rate of force production, i.e explosive strength SSC is the ability of the muscle to absorb force, amortize/stabilise it and finally concentrically produce force.
