Key result
Moderate intensity resistance training with partial blood flow restriction at 50 mmHg resulted in greater handgrip strength than 75 mmHg or no restriction.
Why the study?
The study was conducted to examine the effects of moderate intensity resistance training with blood flow restriction on muscle strength and forearm girth.
Does moderate intensity resistance training with blood flow restriction improve muscle strength and forearm girth in young adult students?

Does moderate intensity resistance training with blood flow restriction improve muscle strength and forearm girth in young adult students?
Moderate intensity resistance training with 50 mmHg blood flow restriction is more effective for improving handgrip strength than training without restriction or with higher restriction in young adults.

50 mmHg BFR augments moderate-RT handgrip gains over 12 days; extends low-pressure BFR evidence in healthy young adults.
OBJECTIVES: To examine the effects of moderate intensity resistance training with blood flow restriction on muscle strength and forearm girth. METHODS: Total of 39 students enrolled in this study were divided into three groups that is group A (control group), group B and group C. Group A performed exercise training without restrictive pressure, group B and C performed exercise training with 50 and 75 mmHg respectively. Both the outcome measures were evaluated on day 1 and day 12th with the help of digital dynamometer and measuring tape. RESULTS: Repeated measure ANOVA with Post hoc analysis was done using SPSS software version 20. The result of the study showed significant (p≤0.05) within subject improvement in muscle strength and muscle girth in all the three groups. However, significant improvement in muscle strength was found in between group analysis (p≤0.05). CONCLUSIONS: The results of the study can be concluded as the partial blood flow restriction (50 mmHg) with moderate intensity resistance training resulted in greater handgrip strength than the other two groups. No difference was found in forearm girth among the three groups, however within the group difference was found.

Gujral et al. (2021) reported an RCT. Moderate intensity resistance training with blood flow restriction vs. Exercise training without restrictive pressure was evaluated on Muscle strength and forearm girth (p=≤0.05). Moderate intensity resistance training with partial blood flow restriction at 50 mmHg resulted in greater handgrip strength than 75 mmHg or no restriction.
