Abstract
Introduction: The aim of this study was to investigate the effects of acute administration of reflexive performance reset (RPR) on muscular power output and muscular fatigue in college-aged male ice hockey players. Methods: In a randomized repeated-measures cross-over design, NCAA Division III college ice hockey players (n=9) performed a 10RM in barbell bench and squat exercises after either a passive range of motion (PROM) sham-control or RPR pre-exercise warm-up routine. Participants were encouraged to move the bar explosively during each repetition, and power produced per repetition was recorded using a Tendo unit attached to the barbell. Results: There was no significant interaction (P= 0.323) in average power produced over time between barbell exercise and intervention. There was no significant interaction (P=0.946) between mean power produced over time and intervention. No significant interactions (P=0.18, 0.18, 0.19) were found for average 10RM, peak, and total power produced between barbell exercises and intervention, respectively.Conclusions: RPR was shown to neither acutely augment, nor reduce, upper or lower body power over 10 repetitions. However, RPR appears to be a practical and safe method to use in conjunction with other pre-exercise neuromuscular activation techniques before athletic events in male athletes, but further work is needed.
