Key result
Low-resistance blood-flow-restricted exercise stimulated angiogenesis and improved endothelial functions more significantly compared to the same training performed without blood flow restriction.
Why the study?
Blood-flow-restricted exercise has gained increasing interest in rehabilitation, but its influence on endothelial functions and angiogenesis has not been well studied.
Does 21-min low-resistant exercise with blood flow restriction improve endothelial functions and angiogenesis in young healthy adults?
Does 21-min low-resistant exercise with blood flow restriction improve endothelial functions and angiogenesis in young healthy adults?
Low-resistance blood-flow-restricted exercise stimulates angiogenesis and improves endothelial function more significantly than the same exercise performed without restriction in healthy adults.
BFRE effects on endothelial function remain uncertain; larger trials needed before any clinical consideration.
Blood-flow-restricted exercise (BFRE) has been gaining constantly increasing interest in rehabilitation, but its influence on endothelial functions has not been well studied yet. Our aim is to examine the influence of low-resistance BFRE on endothelial functions and angiogenesis. This prospective cross-over study involved 35 young healthy adults. They conducted a 21-min low-resistant exercise with blood flow restricted by pressure cuffs placed on arms and tights. They also did the same training but without blood flow restriction. Endothelial parameters and angiogenesis biomarkers were evaluated before and up to 20 min after exercise. Both types of exercise increased Flow-Mediated Dilatation (FMD) but elevation after BFRE was more significant compared to the controls. The stiffness index decreased only after BFRE, while the reflection index decreased significantly after both types of exercise but was higher after BFRE. Platelet endothelial cell adhesion molecule (PECAM-1) and vascular endothelial growth factor receptor 2 (VEGFR-2) concentrations were increased by both exercise types but elevations were higher after BFRE compared to the controls. Only BFRE elevated the mean serum CD34 protein concentration. Based on these results, we can assume that low-resistance BFR exercise stimulates angiogenesis and improves endothelial functions more significantly compared to the same training performed without blood flow restriction.

Maga et al. (2022) studied Healthy (n=35). Low-resistance blood-flow-restricted exercise (BFRE) vs. Same training without blood flow restriction was evaluated on Endothelial parameters and angiogenesis biomarkers. Low-resistance blood-flow-restricted exercise stimulated angiogenesis and improved endothelial functions more significantly compared to the same training performed without blood flow restriction.
