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 ...

Caffeine improves performance but not duration of the countermovement jump phases [PDF]

The Journal of Sports Medicine and Physical Fitness, 2021
The countermovement jump (CMJ) test is often employed to assess power generated in the lower limbs and has been related to performance in several sports modalities. The objective of this study was to assess the effects of caffeine supplementation on jump height, average power (AP), peak power (PP), maximum velocity (Vmax), force production and duration
