Key result
Resistance training with blood flow restriction improved arterial compliance more than resistance training alone, and improved vascular function when training duration was four weeks or less.
Why the study?
The study was conducted to examine the effects of resistance training with and without blood flow restriction on vascular function.
Does resistance training with blood flow restriction improve vascular function and arterial compliance compared to resistance training without blood flow restriction?
Meta-Analysis
Does resistance training with blood flow restriction improve vascular function and arterial compliance compared to resistance training without blood flow restriction?
Resistance training with blood flow restriction improves arterial compliance more than standard resistance training, and improves vascular function specifically in short-term training protocols of four weeks or less.
Supports BFR-augmented resistance training for arterial compliance gains; extends evidence on short-term vascular benefits versus conventional protocols.
In this meta-analysis, the aims were to examine the effects of resistance training with and without blood flow restriction on vascular function. Five databases were searched up to June 2020 for papers about resistance training with blood flow restriction influence on vascular function. The quality of each identified study was evaluated. Effect sizes were estimated in terms of the standardized mean difference. A subgroup analysis was conducted according to participants' age, training duration, and cuff pressure. The results of six studies on arterial compliance and five on vascular function were highly homogenous regarding responses to resistance training with or without blood flow restriction. Resistance training with blood flow restriction had a more positive effect for regulating arterial compliance than resistance training without blood flow restriction, but not for vascular function. Resistance training with blood flow restriction leads to a more positive effect on vascular function than resistance training when training for no longer than four weeks.

Liu et al. (2021) reported a meta-analysis. Resistance training with blood flow restriction vs. Resistance training without blood flow restriction was evaluated on Arterial compliance and vascular function. Resistance training with blood flow restriction improved arterial compliance more than resistance training alone, and improved vascular function when training duration was four weeks or less.
