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 ).
