WebThe Reactive Strength Ratio (RSR) The RSR is a measurement of both the incoming and outgoing momentum of a plyometric landing and its influence on the ground contact. When looking to calculate RSR, the FT before and after a landing should be measured while monitoring GCT. By accounting for both FTs, the incoming approach can be used to … WebThe reactive strength index (RSI) has been developed as a measure of explosive strength and is derived by evaluating jump height divided by ground contact time during the depth jump (DJ). At present, the RSI is typically used to evaluate DJ performance, because it is the only plyometric exercise with an identifiable ground contact time.
