Twelve weeks of protein supplementations improves muscle mass

Statement of the Problem: Muscle mass declines with age, starting in the 40s and picking up speed after about age 50. Protein supplementation (PS) is a positive strategy to prevent sarcopenia. Although early prevention is important, most studies have focused on people over 65. Therefore, this study investigated the effect of PS including leucine on muscle Statement of the Problem: Muscle mass declines with age, starting in the 40s and picking up speed after about age 50. Protein supplementation (PS) is a positive strategy to prevent sarcopenia. Although early prevention is important, most studies have focused on people over 65. Therefore, this study investigated the effect of PS including leucine on muscle condition in both middle-aged and older adults. Methodology & Theoretical Orientation: A 12-week randomized, doubleblinded, placebo-controlled clinical trial was done on the subjects of 120 community-dwelling healthy adults in their 50s -80sStatement of the Problem: Muscle mass declines with age, starting in the 40s and picking up speed after about age 50.
