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.
WebAs RSI is a measure of reactive strength, it must therefore be tested while performing an explosive / reactive movement. To calculate RSI, we require the athlete to perform a … WebJul 15, 2024 · Reactive strength can be defined as the ability to quickly change from an eccentric motion into a concentric muscular contraction The action of the SSC can be seen as a spring, during the eccentric phase, the active muscles (and non-contractile elements as well) stretch and absorb energy 6–8.
