This systematic review and meta-analysis evaluated the effects of blood flow restriction training (BFRT) on endothelial function and arterial stiffness across 35 trials involving 764 participants. The results indicated no overall advantage of BFRT for flow-mediated dilation (FMD) or pulse wave velocity (PWV). However, low-load resistance BFRT improved FMD, while certain protocols, particularly those lasting less than four weeks, were detrimental.
Key findings
- BFRT showed no significant advantage for flow-mediated dilation (FMD; g = -0.10).
- Low-load resistance BFRT improved FMD (g = 0.56).
- Interventions lasting less than 4 weeks decreased FMD (g = -0.69).
- Low-load BFRT reduced pulse wave velocity (PWV) compared to high-load resistance training (g = -0.76).
Why it matters
Understanding the vascular effects of different exercise modalities is crucial for developing effective rehabilitation strategies for cardiovascular health. This study highlights the importance of training protocols in optimizing vascular outcomes.
