Abstract
- To investigate the effects of exercise in combination with, or without, a leucine-enriched whey protein supplement on muscle mass, fat mass, myoelectrical muscle fatigue and health-related quality of life (HR-QOL) in older adults. 100 community-dwelling older adults [52% women, age: 69 ± 6 years (mean ± SD)] were randomised to four [Control (C); Exercise (E); Exercise + Protein (EP); Protein (P)] independent groups. E and EP groups completed 16 weeks of exercise [resistance (2 times/week) and functional (1 time/week]. EP and P groups were also administered a leucine-enriched whey protein supplement (3 times/day) based on body weight (1.5 g/kg/day). Muscle and fat mass (bioelectrical impedance analysis), myoelectrical muscle fatigue (surface electromyography) and HR-QOL (WHOQOL-BREF) were measured pre- and post-intervention. At post-intervention, the rectus femoris (E: − 4.8%/min, p = 0.007, ES = 0.86; EP: − 3.3%/min, p = 0.045, ES = 0.58) and bicep femoris (E: − 3.9%/min, p 0.05). Physical exercise is a potent method to improve myoelectrical muscle fatigue and HR-QOL in older adults. However, leucine-enriched whey protein did not augment this response in those already consuming sufficient quantities of protein at trial enrolment.
