Low-Load BFR vs. High-Load Training on Biceps Hypertrophy
Turkey (Türkiye)33 participantsStarted 2025-06-01
Plain-language summary
This study aimed to compare the effects of low-load blood flow restriction resistance exercise (BFR-RE) performed to voluntary failure with traditional high-load resistance exercise (HL-RE) and a control condition on biceps brachii muscle hypertrophy, muscle stiffness, and maximal strength in untrained young men.
Participants completed an 8-week training program, with exercise performed three times per week. Outcomes were assessed using ultrasound imaging, elastography, and one-repetition maximum (1RM) testing. The study evaluates whether low-load BFR training can produce adaptations comparable to high-load resistance training.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
Healthy male participants aged 18-30 years No prior history of structured or specialized resistance training targeting the biceps brachii muscle Normotensive (blood pressure \<140/90 mmHg) Right-handed (to reduce variability related to limb dominance) Willing to provide written informed consent and comply with the study protocol
Exclusion Criteria:
History of orthopedic injury or musculoskeletal disorder affecting the upper extremities Diagnosis of hypertension (≥140/90 mmHg) or cardiovascular disease Any neurological condition affecting motor performance Current participation in any structured resistance training program Use of medications or supplements known to influence muscle metabolism or performance
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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
