Why the study?
Blood flow restriction training and betaine supplementation are emerging modalities that may provide a synergistic stimulus to augment skeletal muscle adaptation.
Does the combination of blood flow restriction training and betaine supplementation augment skeletal muscle adaptation in athletes and the elderly?
Does the combination of blood flow restriction training and betaine supplementation augment skeletal muscle adaptation in athletes and the elderly?
The combination of blood flow restriction training and betaine supplementation is proposed as a novel, low-barrier modality to elicit muscle hypertrophy and strength in athletes and clinical populations.

May offer low-barrier adjunct for muscle adaptation; leaves open confirmation via randomized trials.
Blood flow restriction (BFR) training and betaine supplementation are emerging training tools with growing evidence, potentially providing a synergistic stimulus to augment skeletal muscle adaptation. Betaine may facilitate stretch-mediated anabolism secondary to BFR-induced extracellular-to-intracellular fluid influx, whereby their combination may promote a new, low-barrier avenue for athletes and clinical practitioners to elicit hypertrophy and strength. This review aims to (a) demonstrate existing evidence on BFR- and betaine-mediated skeletal muscle growth, (b) provide rationale for their combination as a superior anabolic stimulus, and (c) advocate for athletes and the elderly as prime demographics for a potentially valuable BFR-betaine synergistic therapy.
