Does low-load BFR training improve respiratory muscle strength and pulmonary function in healthy young male adults?
Low-load blood flow restriction training provides improvements in respiratory muscle strength and lung function that are comparable to conventional resistance training in healthy young men.
Blood flow restriction (BFR) training has been effective on musculoskeletal and physiological systems even at low training intensities. However, data on the effects of BFR training on respiratory muscle strength and pulmonary function are limited. The study aims to investigate the effects of low-load BFR training on respiratory muscle strength and pulmonary function parameters in healthy adults. This prospective study included male participants aged 18–30 years. The study groups consisted of 25 participants in total, 12 who performed BFR training and 13 who did not. The BFR group completed an 8-week resistance exercise program at 20%-40% 1RM (3 sets/30-15-15 repetitions) three days per week. The non-BFR group followed the same exercise protocol without BFR. Pulmonary function (FVC, FEV₁, FEV₁/FVC, PEF) and respiratory muscle strength (MIP, MEP) were assessed using a spirometer. Baseline demographic and clinical variables were similar between groups (p0.05). Significant time effects were observed for MIP, MEP, FVC%, FEV₁%, and PEF% (p0.05). Low-load BFR training is a safe and feasible method that provides improvements in respiratory muscle strength and lung function similar to conventional training. Further studies with longer intervention durations are needed to determine the respiratory system effects of BFR.
Çelik et al. (Mon,) conducted a cohort in Healthy young adults (n=25). Low-load blood flow restriction (BFR) training vs. Same exercise protocol without BFR was evaluated on Respiratory muscle strength (MIP, MEP) and pulmonary function (FVC, FEV1, FEV1/FVC, PEF). Low-load blood flow restriction training provided improvements in respiratory muscle strength and lung function similar to conventional training in healthy young men.
