abstract = {Age-related strength and muscle mass loss is further increased after acute periods of
inactivity. To avoid this, resistance training has been proposed as an effective countermeasure, but the
additional effect of a protein supplement is not so clear. The aim of this study was to examine the
effect of a whey protein supplement enriched with leucine after resistance training on muscle mass
and strength gains in a post-hospitalized elderly population. A total of 28 participants were included
and allocated to either protein supplementation or placebo supplementation following resistance
training for 12 weeks (2 days/week). Physical function (lower and upper body strength, aerobic
capacity and the Short Physical Performance Battery (SPPB) test), mini nutritional assessment (MNA)
and body composition (Dual X-ray Absorptiometry) were assessed at baseline and after 12 weeks of
resistance training. Both groups showed improvements in physical function after the intervention
(p < 0.01), but there were no further effects for the protein group (p > 0.05). Muscle mass did not
improve after resistance training in either group (p > 0.05). In conclusion, 12 weeks of resistance
training are enough to improve physical function in a post-hospitalized elderly population with no
further benefits for the protein-supplemented group.},
