Skeletal Muscle Hypertrophy After Aerobic Exercise Training

Abstract

In Brief Current dogma suggests that aerobic exercise training has minimal effects on skeletal muscle size. We and others have demonstrated that aerobic exercise acutely and chronically alters protein metabolism and induces skeletal muscle hypertrophy. These findings promote an antithesis to the status quo by providing novel perspective on skeletal muscle mass regulation and insight into exercise countermeasures for populations prone to muscle loss. Although not commonly associated with gains in skeletal muscle mass, aerobic exercise stimulates muscle protein synthesis and skeletal muscle hypertrophy.
