Webreactive strength index, and jump momentum. Objective benchmarks (i.e., target setting) cannot be determined for any test metric without the existence or creation of cohort-specific normative data sets. Standardized scores, namely Z-scores, are calculated as multiples of the standard deviation in relation to the mean [17,18]. 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.
WebJun 30, 2015 · On Figure 3: Left, one can observe that three athletes have very low values (~17-23%), indicating that these athletes need to improve their force or in other words they would benefit from a program that would improve their maximum strength (i.e. hypertrophy and neural activation). WebThe reactive strength index (RSI) can be assessed using a depth jump protocol, which allows identification of the athlete's ability to use the SSC function. A bounce depth jump …
Reactive strength index is a measure of an athlete’s ability to cope with landing stresses, absorb force and react. It strongly correlates with sporting activities such as jumping, sprinting, accelerating, and changing direction, and RSI can be improved through a combination of jump training, strength training and … See more The reactive strength index (RSI) is a test designed to measure an athlete’s reactive jump capacity, specifically how well an athlete is able to cope … See more RSI = Jump height / ground contact time. RSI is calculated by dividing the jump height (in meters) by the ground contact time (in seconds). For example, if an athlete jumps 0.389m … See more Whilst there is currently no ‘gold standard’ test for RSI, there are various tests that have been shown to have good validity and reliability.
