Priming Using Contrast Training Exercise

Completed · Not applicable

Conditions studied: Athletic Performance

In brief

This study investigated the effects of a morning complex-contrast training session on afternoon sport-specific and physical performance in competitive judokas. The study focused on identifying whether a stimulus targeting both force and velocity components of the force-velocity curve could induce a "delayed potentiation" effect 6 hours later and whether these responses differed by sex.
