Effects of Blood Flow Restriction and Small-Sided Games on Soccer Passing and Dribbling Stability Under Fatigue
China40 participantsStarted 2026-01-20
Plain-language summary
This study aims to investigate whether applying blood flow restriction (BFR) during small-sided soccer games (SSG) can help soccer players maintain their passing and dribbling stability when they are fatigued. The study includes 40 young male soccer players. Participants will be randomly divided into two groups:
One group will wear pressurized BFR cuffs on their legs (80% of limb occlusion pressure) during a 4v4 training game.
The other group will act as a control, wearing the same cuffs but without any pressure (0% pressure) during the exact same training game.Both groups will complete a 6-week training program, practicing 3 times a week. Before and after the 6-week period, researchers will test the players' physical and technical skills (such as jumping, passing, and dribbling). Importantly, these tests will be conducted both before and immediately after a tiring 45-minute exercise routine to see which training method is more effective at preventing performance drops caused by fatigue.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Young male soccer players. Possess a systematic soccer specific training background and maintain a stable competitive state.
Cleared by the Physical Activity Readiness Questionnaire (PAR-Q), confirming that cardiovascular and metabolic systems can tolerate high-intensity physical testing and blood flow restriction interventions.
Exclusion Criteria:
* Any recent history of neuromuscular or musculoskeletal system injuries. Current smoking habit. Consumption of any sports nutrition supplements or drinks that could significantly affect muscle performance or neural excitability (e.g., creatine, caffeine, beta-alanine) within 3 months prior to the start of the study and throughout the experimental period.
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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?

Loughborough Soccer Passing Test (LSPT) Performance
Timeframe: Baseline (Week 0) and immediately post-intervention (Week 6). At both time points, the test is performed pre-fatigue and immediately post-fatigue.
