Effects of Blood Flow Restriction Exercises on Bone Metabolism: A Systematic Review

Abstract

This study analysed the effect of low-intensity (LI) exercises with blood flow restriction (BFR) on bone metabolism compared with high-intensity (HI) exercises without BFR. The following databases were searched using the keywords therapeutic occlusion training OR BFR training OR vascular occlusion training OR KAATSU training OR ischaemia training AND osteogenesis OR bone biomarkers OR bone metabolic marker OR bone mass OR bone turnover OR osteoporosis OR osteopenia: PubMed, Web of Science, SPORTDiscus, CINAHL, Science Direct, Cochrane and Google Scholar. Two researchers, independently and blindly, selected the studies based on established inclusion and exclusion criteria. Electronic and manual searches located 170 articles published in English; after screening, only four studies showed that BFR training increases the expression of bone formation markers (e.g. bone-specific alkaline phosphatase) and decreases bone resorption markers (e.g. the amino-terminal telopeptides of type I collagen) after both aerobic and anaerobic exercise across several populations. The results of this study show that few studies have confirmed the positive effect of exercise with BFR on bone metabolism, formation and resorption. Furthermore, no methodological standardization of the samples, exercise type, intervention frequency or duration was observed.

Keywords: biomarkers; blood flow restriction; ischaemia; metabolic bone diseases; physical education and training; therapeutic occlusion.
