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. WebOct 27, 2024 · The Reactive Strength Index is a measurement that assesses the stress placed on the muscles as well as their reactive jump capacity. In order to evaluate plyometric performance, the reactive strength index modified is used. The effectiveness of the Reactive Strength Index test can be calculated using one of three approaches.
