Abstract

Resistance training (RT) is effective for improving athletic performance, with specific training loads and volumes dictating the adaptations. A warm-up is necessary to safely and effectively engage in RT: typically with a low intensity aerobic activity, stretching, and movement specific potentiating exercises. Post-activation potentiation (PAP) acutely increases muscular power following a conditioning contraction, though limited research has assessed its use for RT. The purpose of this study was to assess how a PAP warm-up protocol affects volume, rating of perceived exertion (RPE), and peak velocity and power with 75%1RM in the barbell parallel back squat (PBS) exercise across 4 sets. With 26 resistance-trained college aged males, significant differences between sets were found only for repetitions (p < 0.01) and RPE (p < 0.01). A significant interaction effect was found only between interventions and repetitions; only the first sets were significantly different (p = 0.045). These findings suggest a PAP warm-up may increase volume in only 1 set to volitional fatigue. However, the 2.8% increase in volume across all 4 sets could be significant for practical applications in a training program.
