WebAug 19, 2024 · The reactive strength index (and reactive strength ratio), or RSI, is a simple equation used to measure your “plyometric” ability. Simply, it is the relationship between how forcefully you can rebound off the ground and how quickly you can do so. WebReactive strength index is derived from the height jumped in a depth jump, and the time spent on the ground developing the forces required for that jump ( 21 ). Using a contact mat during a depth jump exercise, one calculates the RSI by dividing the height jumped by the time in contact with the ground before take-off ( Figure 1) ( 21 ). Figure 1:
