Purpose. Many studies have investigated the effect of whole body vibration (WbV) exercise on post-activation potentiation. It was reported that an intervention protocol of WbV combined with 5 drop jumps (DJs) led to an increase in twitch force, suggesting the occurrence of post-activation potentiation. the purpose of this study was to examine the a...
