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: WebApr 26, 2024 · Reactive strength has been described as the capacity of an athlete to bear a stretch load and subsequently switch rapidly from an eccentric to concentric muscle action. This strength quality is most important in movements that involve short ground contact phases (<0.250 s) such as running, sprinting, side stepping, jumping and hopping.
