Brief summary
This study investigated the effects of low-load resistance training combined with blood flow restriction (BFRT) compared to traditional high-load resistance training on arm muscle strength and isokinetic contraction parameters in healthy young adults. Participants were prospectively assigned to either a low-load BFRT group or a high-load resistance training group for a 7-week intervention period. Muscle strength and isokinetic peak torque were assessed before and after the intervention. The primary objective was to determine whether low-load BFRT produces comparable improvements in muscle strength and isokinetic performance to high-load resistance training.
Detailed description
his interventional study was designed to compare the effects of low-load blood flow restriction resistance training (LL-BFRT) and high-load resistance training (HL-RT) on arm muscle strength and isokinetic contraction parameters in healthy individuals. A total of 22 healthy young adults were prospectively assigned to either a low-load BFRT group or a high-load resistance training group. The intervention lasted 7 weeks. The low-load BFRT group performed resistance exercises at 30% of one-repetition maximum (1RM) combined with individualized blood flow restriction pressure, while the high-load group trained at 70% of 1RM without blood flow restriction. Primary outcome measures included isokinetic peak torque values of the elbow flexors and extensors. Secondary outcomes included muscle strength assessments. All participants completed pre-intervention and post-intervention evaluations. The study aimed to determine whether low-load BFRT can induce strength and performance adaptations comparable to traditional high-load resistance training, offering an alternative training strategy when high mechanical loads are not desirable.
Interventions
Low-load resistance training performed at 30% of one-repetition maximum with individualized blood flow restriction pressure.
Traditional resistance training performed at 70% of one-repetition maximum without blood flow restriction.

Masking description
This was an open-label study. No masking was applied to participants, investigators, or outcome assessors.
Intervention model description
Participants were prospectively assigned to one of two parallel groups: a low-load blood flow restriction training group or a high-load resistance training group. Both groups completed a 7-week intervention, and outcomes were assessed pre- and post-intervention.
