Aerobic training with blood flow restriction induced greater muscle hypertrophy (SMD 0.86; 95% CI 0.37-1.35) and strength (SMD 0.41; 95% CI 0.10-0.72) than aerobic training without BFR.
Meta-Analysis
Does aerobic training with blood flow restriction improve muscle hypertrophy and strength in healthy individuals aged 18-60 years compared to aerobic training without BFR?
Aerobic training with blood flow restriction is an effective method for concurrently enhancing muscle hypertrophy and strength compared to aerobic training alone in healthy adults.
Standardized Mean Difference: 0.86 (95% CI 0.37–1.35)
ABSTRACT: de Lemos Muller, CH, Farinha, JB, Leal-Menezes, R, and Ramis, TR. Aerobic training with blood flow restriction on muscle hypertrophy and strength: systematic review and meta-analysis. J Strength Cond Res 38(7): 1341-1349, 2024-Integrating strength and endurance training in a single exercise session, even on separate days, can be physically demanding and time-consuming. Therefore, there is a growing interest in identifying efficient training methods that can concurrently enhance cardiovascular and neuromuscular performance through a singular training modality. This study conducted a systematic review and meta-analysis to explore the effects of aerobic training with blood flow restriction (AT + BFR) on muscle hypertrophy and strength gains in healthy individuals. Our study was registered at PROSPERO and used multiple databases (PubMed, Embase, Scopus, and Web of Science), seeking clinical trials that examined AT + BFR influence on muscle hypertrophy and strength gains in individuals aged 18-60 years and comparing with aerobic training without BFR. The risk of bias and method quality were assessed using the ROB2.0 tool and PEDro scale, respectively, and the quality of evidence was evaluated with the GRADE method. A random-effects model was used for meta-analysis, and standardized mean difference (SMD) was calculated for each outcome. Of 4,462 records, 29 full texts were assessed for eligibility, with 7 articles meeting the inclusion criteria. The results indicated that AT + BFR was more beneficial for inducing muscle hypertrophy than aerobic training without BFR (SMD 95% CI = 0.86 0.37-1.35; I2 = 42%). Furthermore, AT + BFR was associated with greater improvements in muscle strength (SMD 95% CI = 0.41 0.10-0.72; I2 = 0%). Despite the generally high risk of bias for both outcomes, these encouraging findings underscore the clinical significance of AT + BFR as a compelling tool for enhancing neuromuscular parameters.
Muller et al. (Thu,) conducted a meta-analysis in Healthy individuals. Aerobic training with blood flow restriction (AT + BFR) vs. Aerobic training without BFR was evaluated on Muscle hypertrophy (SMD 0.86, 95% CI 0.37-1.35). Aerobic training with blood flow restriction induced greater muscle hypertrophy (SMD 0.86; 95% CI 0.37-1.35) and strength (SMD 0.41; 95% CI 0.10-0.72) than aerobic training without BFR.
