Effect of drop jump technique on the reactive strength index [PDF]

Journal of Human Kinetics, 2016
Abstract The basic drill of plyometric training aimed at improving lower limb power and jump height is a drop jump. This exercise can be performed using different techniques, which substantially affects jump variables. Therefore, the aim of this study was to compare the values of the reactive strength index (RSI) for countermovement drop

REACTIVE STRENGTH INDEX IN SPORT

International Refereed Journal of Humanities and Academic Sciences, 2023
Aim: This study aims to examine the effect of reactive strength index in sport. Athletes have different muscle activation at different intensities and durations while performing. One of these actions is the stretch-shortening cycle. Tension-shortening cycle (TSC) is an important component of the ability to produce force in minimum time.

Catalysis by zymogens: increased reactivity at high ionic strength [PDF]

FEBS Letters, 1979
Kinetic analysis of the intrinsic activity of trypsinogen and chymotrypsinogen has shown that a major cause for the diminished activity of these zymogens, as compared to the corresponding enzymes, is a deformation of the primary binding site [l-6] .

Reactivity, stability, and strength performance capacity in motor sports [PDF]

British Journal of Sports Medicine, 2006
Background: Racing drivers require multifaceted cognitive and physical abilities in a multitasking situation. A knowledge of their physical capacities may help to improve fitness and performance. Objective: To compare reaction time, stability performance capacity, and strength performance capacity of

Resistance training for sprinters : the role of maximum strength, reactive strength and exercise selection

, 2019
Each distinct phase of a 100 m sprint is dependent on key race variables e.g. acceleration ability, maximum velocity and speed endurance. Consequently, sprinters frequently supplement their sprint training with resistance training to develop qualities such as maximum strength and reactive strength. The literature assessing the association between these

Optimal Reactive Strength Index

, 2018
This study aimed to compare the effects of drop-jump training using a fixed drop-box height (i.e., 30-cm [FIXED]) vs. an optimal (OPT) drop-box height (i.e., 10-cm to 40-cm: generating an OPT reactive strength index [RSI]) in youth soccer players' physical fitness.
