WebRSI = Flight Time / Ground Contact Time. Time To Take-Off (TTT) can be substituted for Ground Contact Time if the movement being performed is a Countermovement Jump. There is no unit for RSI. mRSI stands for Modified Reactive Strength Index. mRSI is the ratio of Jump Height & Ground Contact Time. mRSI = Jump Height / Ground Contact Time. 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:
