Abstract
Objective: The aim of this study was to evaluate and compare the effects of back squat exercise on subsequent sprint performance in resistance-based Post Activation Performance Enhancement (PAPE) intervention with two different loads and repetitions. Material and Methods: Subjects performed three experimental runs in the laboratory for at least 48 hours apart. At the first experimental visit, anthropometric evaluations, sprint performance and one-repetition maximum (1RM) tests were performed. On the next two visits, each subject completed a standardized warm-up on the bicycle ergometer at 30 watt/ 60 cadence for 5 minutes, and after a passive transition phase period of 5 minutes, they performed the resistance based back squat PAPE protocol. After a 12-minute passive transition phase period, subjects performed the sprint cycling performance. Results: PAPE interventions with 1RM%60x6 reps (moderate rep-moderate load) and 1RM %90x3 reps (low rep-high load) loads resulted in statistically insignificant slight improvement in mean power values (p<0.47), and no significant effect on peak power (p<0.91), and fatigue index (p<0.79) in sprint cycling performance. Conclusion: The PAPE interventions resulted in a slight increase in the mean power values when compared to the control condition. However, there was no statistically significant difference between the two differential loads.
