LOAD THAT MAXIMIZES POWER OUTPUT IN COUNTERMOVEMENT JUMP [PDF]
Revista 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.

Effects of Concurrent Activation Potentiation on Countermovement Jump Performance [PDF]
Journal of Strength and Conditioning Research, 2015 The purpose of this study was to assess the effects of concurrent activation potentiation (CAP) on countermovement jump (CMJ) performance. Twenty-four resistance-trained males (mean ± SD; age: 25 ± 4 years, body mass: 78.7 ± 10.3 kg) performed a CMJ on a force plate under 4 different conditions: (a) a control condition where the CMJ was performed with ...

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