WebJul 1, 2024 · Reactive Strength Index: A Poor Indicator of Reactive Strength? The method of assessing reactive strength (RSI vs RSR) may be influenced by the performance … WebIntroduction. Strength and power training are training modalities commonly used by Strength & Conditioning (S&C) coaches, as both qualities underpin the execution of many essential athletic skills in a variety of sports (Suchomel 2016). As an S&C coach, many vertical lower-body power tests measure an athlete’s maximum power capabilities.

WebNov 21, 2024 · Reactive strength may be one of the most powerful indicators of athleticism, as it represents the ability to effectively make use the stretch shortening cycle (SSC). It is an expression of the ability to change from an eccentric to a concentric contraction as quickly as possible and with as much force as possible. WebA recent approach proposes to use an indirect index linked to the leg stiffness: the reactive strength index, which is the ratio of the height jumped on the contact time. Curiously, we...
WebReactive Strength Index (RSI), which is a depth jump with a look at height divided by ground contact time. The RSI gives a better look at the central nervous system, while the lifts look closer at the peripheral nervous system. Velocity is the simplest way to measure fatigue.
