Official title
Independent and Combined Effects of Resistance Exercise Training and β-hydroxy β-methylbutyrate Plus Vitamin D on Body Composition and Skeletal Muscle Health
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
During middle-age, humans begin to lose muscle mass and strength. With increasing age the deterioration of muscle health is associated with a decline in quality of life and the loss of independence. β-hydroxy β-methylbutyrate (HMB) plus Vitamin D (VitD) have been proposed to increase skeletal muscle mass, contractile function and improve body composition but has yet to be evaluated in middle-aged women. The overall goal of this study is to determine the effects of HMB +VitD supplementation during 12 weeks of resistance exercise training or a non-exercise control on body composition, skeletal muscle size, and skeletal muscle function in middle-aged women.
