Squat Depth Effects on Muscle Activation and Jump Performance
ClinicalTrials.gov Studies
Summary
This registry entry documents a randomized crossover study registered with ClinicalTrials.gov (NCT07543237) examining how different squat depths affect lower extremity muscle activation and jump performance in healthy sports science students.
What changed
This is a ClinicalTrials.gov study registration entry, not a regulatory action. The study registered as NCT07543237 examines the acute effects of different squat depths on lower extremity muscle activation (vastus lateralis, rectus femoris, biceps femoris) and countermovement jump performance using a randomized crossover design with 14 participants.
Affected parties: This registry entry has no compliance implications. It is informational documentation of a sports science research study and does not create regulatory obligations.

The Acute Effect of Squat Exercises Performed at Different Depths on Muscle Activation and Jump Performance
N/A NCT07543237 Kind: NA Apr 21, 2026
Abstract
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.
Conditions: Healthy, Physical Performance
Interventions: Partial Squat Exercise, Parallel Squat Exercise, Full Squat Exercise
