NCT07765732

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Countermovement jump height

    Countermovement jump height calculated from the vertical velocity of the center of mass at take-off.

    Baseline, 3, 6, 9, and 12 minutes after completion of the final squat set

Secondary Outcomes (5)

  • Countermovement depth

    Baseline, 3, 6, 9, and 12 minutes after completion of the final squat set

  • Eccentric velocity

    Baseline, 3, 6, 9, and 12 minutes after completion of the final squat set

  • Relative peak power

    Baseline, 3, 6, 9, and 12 minutes after completion of the final squat set

  • Contraction time

    Baseline, 3, 6, 9, and 12 minutes after completion of the final squat set

  • Reactive strength index-modified

    Baseline, 3, 6, 9, and 12 minutes after completion of the final squat set

Study Arms (2)

Squat-only Conditioning Activity

EXPERIMENTAL

Participants performed three sets of three back squat repetitions at 85% of one-repetition maximum, with 3-minute recovery intervals between sets. No additional exercise was performed during the inter-set recovery periods.

Behavioral: Back Squat Conditioning Activity

Squat Plus Bench Press Conditioning Activity

EXPERIMENTAL

Participants performed three sets of three back squat repetitions at 85% of one-repetition maximum, with 3-minute recovery intervals between sets. In addition, participants performed three bench press repetitions at 75% of one-repetition maximum, initiated 90 seconds after each squat set during the inter-set recovery periods.

Behavioral: Bench Press During Inter-Set Recovery

Interventions

Participants performed three sets of three back squat repetitions at 85% of one-repetition maximum, with 3-minute recovery intervals between sets.

Squat-only Conditioning Activity

Participants performed three bench press repetitions at 75% of one-repetition maximum, initiated 90 seconds after each squat set during the inter-set recovery periods. This intervention was administered only to participants in the squat plus bench press group.
