The Acute Effect of Squat Exercises Performed at Different Depths on Muscle Activation and Jump Performance
Sponsor: Pamukkale University
Summary
This study examined the acute effects of different squat depths (partial, parallel, full) on lower extremity muscle activation and jump performance (countermovement jump - CMJ). Fourteen healthy sports science students participated in this randomized crossover study. Participants performed three sets of squats at their 5-repetition maximum (5RM) load across three different depths. Surface electromyography (SEMG) was recorded from the vastus lateralis (VL), rectus femoris (RF), and biceps femoris (BF) muscles during each set, while CMJ performance was assessed before and after the squat protocols.
