Key result
High-load training with blood flow restriction shows no strength or size benefit over conventional training.
Why the study?
While blood flow restriction enhances muscle adaptations with low loads, findings are conflicting regarding its effects when combined with higher resistance training loads of 60% or more of maximal strength.
Does high-load resistance training with blood flow restriction improve muscle size and strength in healthy adults compared to conventional high-load resistance training?

No benefit from adding BFR to high-load training; challenges its adjunctive use at higher loads and confirms efficacy is limited to low-load protocols.
Meta-Analysis
Does high-load resistance training with blood flow restriction improve muscle size and strength in healthy adults compared to conventional high-load resistance training?
Standardized Mean Difference: 0.11 (95% CI -0.11–0.33)
Adding blood flow restriction to high-load resistance training does not provide additional benefits for muscle size and strength in healthy adults.
McKee et al. (2026) conducted a meta-analysis in Healthy adults. High-load resistance training with blood flow restriction vs. Conventional high-load resistance training was evaluated on Muscle strength (g 0.11, 95% CI -0.11 to 0.33). High-load resistance training with blood flow restriction does not further improve muscle strength (g=0.11; 95% CI -0.11 to 0.33) or size compared with conventional high-load resistance training.
