Effects of Heavy Back-Squat PAPE on Jump and Repeated Sprint Performance in Trained Soccer Players
Sponsor: Istanbul University - Cerrahpasa
Summary
This study examined whether performing heavy back squats before exercise affects jumping ability and repeated sprint performance in trained soccer players. Twenty male university soccer players completed two testing sessions in a randomized crossover design. In one session, participants performed a standardized warm-up only. In the other session, they performed the same warm-up followed by three sets of three back-squat repetitions at 90% of their one-repetition maximum. The two sessions were separated by one week. After each condition, participants completed a countermovement jump test and an 18 × 40-meter repeated sprint test. The study aimed to determine whether the heavy back-squat activity improves early explosive performance and whether it increases fatigue during prolonged repeated sprint exercise.

Heavy Back-Squat PAPE Protocol
Participants completed a standardized warm-up followed by a heavy back-squat conditioning activity consisting of three sets of three repetitions at 90% of one-repetition maximum. Three minutes of passive recovery were provided between sets. Countermovement jump performance was assessed approximately 4.5-5 minutes after the final squat set, immediately before the repeated sprint test.
Standardized Warm-Up Control Condition
Participants completed a standardized warm-up consisting of 5 minutes of jogging, followed by 10 bodyweight squats, 10 lunges, and 10 lateral shuffles. No additional conditioning activity was performed. After approximately 5 minutes of passive recovery, countermovement jump performance was assessed immediately before the repeated sprint test.
