The Effect of two Different Protocols: Post-Activation Potentiation (with and without Occlusion) on Anaerobic Performance Athletes

The aim of this study was to investigate the effect of two different protocols of post-activation potentiation on anaerobic performance of female athletes. For this purpose, in a randomized crossover design, 12 female athlete students were assigned to 4 groups: control (ordinary and traditional warm-up and then Wingate test), experiment 1 (3 sets of squat with 80% of one repetition maximum and then Wingate test), experiment 2 (3 sets of squat with 20% of one repetition maximum with vascular occlusion and then Wingate test), experiment 3 (ordinary warm-up and then Wingate test, just vascular occlusion). In order to measure the power, one repetition maximum in the squat test was used. Data were analyzed using one-way analysis of variance with repeated measures. According to the results, no significant difference was observed in the peak power, average power, and minimum power among four different groups (experiment 1, experiment 2, experimental 3 and control) (P˃0.05). The results showed that the 3 sets of squat with 20% and 80% of one repetition maximum and 10 repetitions (with or without vascular occlusion) had no effects on the output of anaerobic power in female athletes. Probably, pre-activation before power actions should be performed more strongly or with a longer rest interval.
