Relationship between Rapid Strength, Reactive and Strength and Agility in University Sports Students [PDF]
International Journal of Human Movement and Sports Sciences, 2022 Sports training is a complex phenomenon which, to be effective for the planned purposes, must consider all the aspects that make it up. Agility, rapid strength, and reactive strength are factors that contribute, at various levels and in an integrated mood, to the achievement of sporting performance.

Establishing a Kinetic Assessment of Reactive Strength [PDF]
, 2017 The reactive strength index (RSI) is the current “gold standard” assessment of reactive strength. Traditional measures of reactive strength, including the RSI, are not strength-based and are founded using untested theoretical assumptions. The purpose of this study was to develop two versions of a kinetic-based paradigm of reactive strength (New and ...
