Influence of countermovement depth on the countermovement jump‐derived reactive strength index modified

open access: yesEuropean Journal of Sport Science, 2020
AbstractThis study aimed to investigate the effect of countermovement depth on the magnitude of the countermovement jump (CMJ) derived reactive strength index modified (RSImod), and to compare the RSImod between the CMJ performed with a self‐preferred knee flexion angle (CMJpref) and the CMJ performed from a pre‐determined knee flexion angle (CMJrefer)

LOAD THAT MAXIMIZES POWER OUTPUT IN COUNTERMOVEMENT JUMP [PDF]

open access: yesRevista Brasileira de Medicina do Esporte, 2016
ABSTRACT Introduction: One of the main problems faced by strength and conditioning coaches is the issue of how to objectively quantify and monitor the actual training load undertaken by athletes in order to maximize performance. It is well known that performance of explosive sports activities is largely determined by mechanical power.

The Ecological Validity of Countermovement Jump to On-Court Asymmetry in Basketball

open access: yesSports Medicine International Open, 2022
AbstractJump-based asymmetry is often used as an indicator of sport performance and may be used to discern injury susceptibility. Due to task specificity, however, countermovement jump asymmetry may not be representative of on-court asymmetry.
