Low-Load BFR vs. High-Load Training on Biceps Hypertrophy
Sponsor: Mehmet Akif Ersoy University
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.

Interventions
Blood Flow Restriction Resistance Exercise
Resistance exercise was performed under partial vascular occlusion using a pneumatic cuff applied to the upper arm. Limb occlusion pressure was individually determined, and exercise was conducted at a relative intensity corresponding to a percentage of one-repetition maximum. Occlusion pressure was maintained during sets and released between exercises. Training load and repetition tempo were standardized and progressively adjusted throughout the intervention period.
High-Load Resistance Exercise
Participants performed resistance exercise using conventional loading strategies based on a percentage of one-repetition maximum. Training intensity, volume, and progression were standardized across sessions, with loads adjusted periodically according to performance assessments.
