AN ANALYSIS OF THE POSTACTIVATION POTENTIATION EFFECT OF THE PRIMARY GLUTEAL MUSCLES FOLLOWING HABITUALLY PRESCRIBED ACTIVATION AND COMDlT IONlNG EXERCISES

Abstract

This study examined the effects of a high load gluteal activation protocol on counter movement jump (CMJ) performance and gluteal activation levels. Eight sprinters performed 5 CMJ's prior to and subsequently after a gluteal activation protocol on two separate days. Height jumped (HJ), peak force (Forcewk), modified reactive strength index (RSId) and electromyographic gluteal activation levels were calculated on both days. Paired samples T tests found no significant differences for all reported variables on either day. This suggests that the gluteal activation protocol had no effect on CMJ performance. Future research should incorporate typical error analysis to investigate potentiation effects on an individual basis due to individual nature of the postactivation potentiation response and biological variability.
