Bench Press During Squat Conditioning and PAPE

The goal of this clinical trial is to learn whether adding a moderate-load bench press exercise during the recovery periods between sets of back squats affects subsequent jumping performance in competitive male basketball players. The main questions it aims to answer are: Does adding bench press exercise during recovery periods affect countermovement jump height following the squat conditioning activity? Does adding bench press exercise affect the timing and magnitude of the post-activation performance enhancement response? Researchers will compare a squat-only group with a squat plus bench press group to see if performing bench press exercise during the recovery periods affects subsequent jumping performance. Participants will: Perform three sets of three back squat repetitions at 85% of their one-repetition maximum, with 3-minute recovery periods between sets. Participants in the squat plus bench press group will additionally perform three bench press repetitions at 75% of their one-repetition maximum during the recovery periods. Perform countermovement jumps before the conditioning activity and 3, 6, 9, and 12 minutes after the final squat set.
