Blood Flow Restriction Only Increases Myofibrillar Protein Synthesis with Exercise.

ABSTRACT: PURPOSE:Combining blood flow restriction (BFR) with exercise can stimulate skeletal muscle hypertrophy. Recent observations in an animal model suggest that BFR performed without exercise can also induce anabolic effects. We assessed the effect of BFR performed both with and without low-load resistance-type exercise (LLRE) on in vivo myofibrillar protein synthesis rates in young men. METHODS:Twenty healthy young men (age = 24 ± 1 yr, body mass index = 22.9 ± 0.6 kg·m) were randomly assigned to remain in resting condition (REST ± BFR; n = 10) or to perform LLRE (LLRE ± BFR at 20% one-repetition maximum; n = 10), combined with two 5-min cycles of single leg BFR. Myofibrillar protein synthesis rates were assessed during a 5-h post-BFR period by combining a primed continuous L-[ring-C6]phenylal
