A Comparison Of The Effect Of Conditioning Activity Type On Post-Activation Potentiation, Alexander I. Grey

WWU Graduate School Collection

This study compared the effects of two conditioning exercise types on subsequent countermovement jump performance. Fifteen male collegiate rugby players (age 21.1 ± 2.3) completed two experimental protocols in a randomized order. The first protocol consisted of 3 sets of a 5 second maximal isometric half squat (ISO), with 1 minute rest intervals between sets. The second protocol consisted of 2 sets of 5 depth jumps (DJ) at a platform height which was determined by the athletes’ reactive strength index (RSI). These methods were each adapted from prior literature where post-activation potentiation (PAP) was achieved, in order to determine the …
