15% vs 30% squat speed loss: effects on leg strength and endurance in young women
Effect of 15% Versus 30% Intra-Set Velocity Loss Thresholds During Bodyweight Squats on Lower-Limb Strength and Muscular Endurance in Non-Athletic Young Female Adults.
This program will test whether allowing squat speed to drop by 15% versus 30% during bodyweight squats helps non-athletic women aged 18–25 build more lower-limb strength or muscular endurance.

What this trial studies
This randomized controlled trial will enroll 52 non-athletic female university students aged 18–25 and randomly assign them to either a 15% or 30% intra-set velocity loss threshold during bodyweight squat sessions. Both groups will perform supervised bodyweight squats three times per week for six weeks, with training volume regulated by the set velocity loss threshold. Lower-limb strength and muscular endurance will be measured before and after the intervention by a blinded assessor. Data will be analyzed using SPSS with significance set at p < 0.05 to compare changes between groups.
Who should consider this trial
Good fit: Healthy, non-athletic women aged 18–25 with BMI under 30 and low physical activity who can perform bodyweight squats without pain are ideal candidates.
Not a fit: People currently in resistance or endurance training programs, those with recent musculoskeletal or cardiovascular injuries, pregnant or recently postpartum individuals, or anyone unable to perform squats safely are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, the study could identify a simple, equipment-free squat method that improves leg strength or endurance in young women.
How similar studies have performed: Velocity-based training has shown benefits in trained male athletes using loaded exercises, but equipment-free bodyweight velocity-loss approaches in non-athletic young women are largely untested.
