Reactive strength index definition
WebFeb 17, 2024 · Reactive strength is the ability to rapidly and efficiently transition from an eccentric to a concentric muscle contraction within a SSC movement [ 14 ]. The SSC is present during many sporting activities, such as sprinting and jumping [ 15, 16 ]. WebMay 19, 2024 · Although reactive strength has been proposed as a major NMP quality underpinning deceleration performance (Kovacs et al., Citation 2008), this is the first study to report significant and large associations between reactive strength, characterised by DJ RSI, and maximal horizontal deceleration ability in team sport athletes.
