摘 要：Aim The concept of post-activation potentiation(PAP)is still novel from a training perspective and lacks breadth relative to weightlifting exercises.Purpose The purpose of this study was to investigate the acute effects of a conditioning activity(clean high pulls)on the performance of a main activity(clean)after the conditioning activity.Methods Eleven volunteers who engaged in weightlifting(Male=5,Female=6)participated in two different testing ses-sions(experimental vs.control).Baseline measurements were taken following the warm-up.The testing condition was performed and additional measurements were taken at 30 s,2 min,4 min,6 min,8 min,10 min,and 12 min into recovery.A linear position transducer was used to collect peak power,peak velocity,and displacement of the barbell during the clean.Multiple 2×8 repeated measures ANOVAs were used to analyze the data along with a paired samples t test between baseline andbestvalues.Results There was no interaction or main effect for condition(P0.05).However,there was a significant main effect for time(P0.05)for all variables.Thebestvalues were significantly(P0.05)greater than baseline values(peak power:experimental=1354.76 ±521.24 W vs.baseline 1216.03 ±492.30 W;peak velocity:experimental=2.66 ±0.44 m/s vs.baseline 2.50 ±0.44 m/s;displacement:experimental=111.07 ± 12.09 cm vs.baseline 107.01 ± 11.32 cm).Conclusions The findings of this study are in partial agreement with previous literature where the warm-up was probably enough to elicit PAP.Therefore,recommendations for future studies could include utilizing a more elite population and to ensure all potential participants can squat at least 2 x their body weight.
