Full Squats Enhance Performance and Body Composition, but Not Hypertrophy, Compared to Half Squats in Elite Young Tennis Players

Randomized Controlled Trial
Human
2025 Nov 13

Both deep and shallow squats made the players' legs bigger by about the same amount, even though deep squats helped them jump higher and lose more fat. So, for building leg muscle, depth didn’t matter.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Deep squats don’t make leg muscles bigger than shallow squats if you do the same number of reps and same weight—muscle growth is about total work, not how deep you go.

Even though deep squats move your legs through a bigger range, they don’t make your muscles bigger than shallow squats—if you’re doing the same number of reps and weights.

Deep squats help young tennis players lose more body fat than shallow squats—even when they do the same number of reps and weights—possibly because they work harder and burn more energy.

For young tennis players, doing deep squats instead of shallow ones for 8 weeks makes them faster and stronger when pushing off the ground, and helps them lose body fat—without making their leg muscles bigger than shallow squats do.

Whether you squat deep or shallow, doing squats twice a week for 8 weeks makes young tennis players stronger and leaner—depth matters for how much, but doing squats at all is what gets the job done.
