About

The study investigated the effects of three contrast training sessions in a week on post-activation countermovement jump performance in high strength male.

Full description

Previous researches indicated that the primary contributor of contrast training to improving explosive performance might be the phenomenon of post-activation performance enhancement (PAPE), with emphasis on conducting plyometric training at the optimal PAPE time. However, the PAPE appeared to be susceptible to fatigue and delayed potentiation of neuromuscular performance. Thus, its applicability in practical training is not yet clarified. The purposes of this study are to: 1) examine the effects of three contrast training sessions in a week on individual and group's PAPE and the optimal timepoint of PAPE; 2) assess the intrasession and intersession reliability of the optimal PAPE timepoints of both individuals and groups; 3) determine the relationship between kinematic parameters during resistance training and PAPE.

Qualified participants will visit the laboratory five times for experimental familiarization, One repetition maximum (1RM) of parallel squat test, and three contrast training sessions, with each contrast training session consisting of three sets of parallel squats in a week. Alongside this, countermovement jump tests will be conducted before the first set of squats and at 1, 3, 5, 7, 9, and 11 minutes after each squat set, with the kinematic parameters of the parallel squats also being collected.
