![]() ![]() Blood flow restriction exercise stimulates mTORC1 signaling and muscle protein synthesis in older men. ![]() Combined effects of low-intensity blood flow restriction training and high-intensity resistance training on muscle strength and size. Yasuda T, Ogasawara R, Sakamaki M, et al. Effects of cuff width on arterial occlusion: implications for blood flow restricted exercise. Muscular adaptations in response to three different resistance-training regimens: specificity of repetition maximum training zones. All rights reserved.Ĭampos GE, Luecke TJ, Wendeln HK, et al. Blood flow restriction training is potentially beneficial to those unable to tolerate the high loads of HIRT however, better understanding of its risk to benefit ratio is needed before clinical application.Ĭopyright © 2021 Wolters Kluwer Health, Inc. However, LI-BFR was superior when compared with a similar low-intensity protocol. Comparing LI-BFR training with HIRT, HIRT was a significantly better training modality for increasing muscle hypertrophy and strength. Assessing endurance, V̇o2 maximum demonstrated a greater mean increase of 0.37 mL/kg/min (95% CI, -0.97 to 3.17 P = 0.64) in BFR endurance training compared with endurance training alone.īlood flow restriction training produced increases in muscular strength, hypertrophy, and endurance. Assessing muscle hypertrophy, the MD in cross-sectional area was 0.96 cm2 (95% CI, 0.21-1.7 P = 0.01) favoring pooled BFR training compared with nonocclusive training. However, comparing LI-BFR with low-intensity resistance training (LIRT) for torque, there was a MD of 9.94 N When comparing LI-BFR training with HIRT for torque, the MD was 6.35 N For muscular strength comparing low-intensity BFR (LI-BFR) training with high-intensity resistance training (HIRT), the pooled mean difference (MD) for 1 repetition maximum was 5.34 kg (95% CI, 2.58-8.09 P < 0.01) favoring HIRT. We included 53 randomized controlled trials with 31 included in meta-analyses. We performed systematic searches of MEDLINE, Embase, and PubMed and assessed the methodological quality of included studies using the Cochrane risk of bias tool. This study investigates the effectiveness of BFR training relative to other forms of training on muscle strength, hypertrophy, and endurance. Blood flow restriction (BFR) training is an increasingly applied tool with potential benefits in muscular hypertrophy, strength, and endurance. ![]()
