Effects of Resistance Exercise Timing on Midday Muscle Performance in Athletes
Sponsor: Manisa Celal Bayar University
Summary
This study investigated whether the timing of a resistance-based post-activation performance enhancement (PAPE) intervention performed during the morning influences muscle performance and muscle electrical activity during a standardized midday assessment in trained male athletes. Participants completed a control condition and three PAPE conditions performed at different times during the morning. The PAPE intervention consisted of back squat, kettlebell swing, and barbell hip thrust exercises. In all conditions, muscle performance was assessed between 12:00 and 12:15 using an isokinetic dynamometer, while surface electromyography (sEMG) of the rectus femoris muscle was recorded. The study compared relative peak torque and sEMG spectral power across the different PAPE timing conditions and the control condition.

Interventions
Resistance-Based PAPE Intervention
The resistance-based PAPE intervention consisted of three exercises performed in the following order: back squat, kettlebell swing, and barbell hip thrust. Participants performed one set of six repetitions at 80% of their individual estimated one-repetition maximum (e1RM) for each exercise, with a 1-minute rest interval between exercises. The intervention was preceded by a 5-minute standardized cycling warm-up at 60 rpm followed by 5 minutes of passive rest. The same PAPE protocol was performed in the T1, T2, and T3 conditions at different times before the standardized midday performance assessment.
