Load-Matched Unilateral Versus Bilateral Squat Training in Elite Youth Futsal Players
Colombia17 participantsStarted 2023-08-01
Plain-language summary
This randomised controlled trial compared the effects of two load-matched squat training modalities on physical performance in elite youth futsal players. Seventeen players from the Antioqueña regional futsal squad in Colombia were randomly allocated to either a unilateral squat training group or a bilateral squat training group. Both groups completed a six-week velocity-based training programme, with two supervised sessions per week, while continuing their usual futsal training.
Training intensity was prescribed using mean propulsive velocity targets across three two-week blocks. The main outcomes were countermovement jump height, single-leg countermovement jump height for the right and left limbs, 10-metre sprint time, and estimated squat one-repetition maximum. Secondary descriptive data included 20-metre sprint time. The study aimed to determine whether unilateral squat training produced superior adaptations compared with bilateral squat training when training load was objectively standardised.

Inclusion Criteria:
* Competitive futsal experience of at least two years.
* Affiliation with the Antioqueña regional futsal squad.
* Technical proficiency in bilateral squat and single-leg squat execution, verified by an accredited specialist.
* No musculoskeletal injury during the three months before enrolment.
* No pharmacological, ergogenic, or supplementary intervention likely to influence physical performance.
* Exclusive participation in standard futsal training during the intervention period.
* Written informed assent from the participant and written informed consent from a parent or legal guardian when required by age.
Exclusion Criteria
* Musculoskeletal injury during the three months before enrolment.
* Inability to perform bilateral or single-leg squat exercises with acceptable technique.
* Participation in another structured lower-limb strength training programme during the study period.
* Use of pharmacological, ergogenic, or supplementary interventions likely to affect performance.
* Failure to complete baseline testing, the training intervention, or post-intervention testing.
* Withdrawal of participant assent or parental/legal guardian consent.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
