Finally , muscle power testing was found to be safe in older people with a broad range of health and functional states
Background Muscle power has been proposed to be the primary therapeutic target for resistance training interventions aim ed at enhancing physical function in older adults .
However , no recommendations exist on ideal testing protocol s to assess muscle power in older adults , and the safety of this procedure has not been adequately evaluated in the literature .
Methods A systematic review was conducted to identify studies evaluating muscle power exerted by older people in resistance exercises through May 2017 .
Efficacy of whey protein supplementation on resistance exercise-induced changes in lean mass, muscle strength, and physical function in mobility-limited older adults.
BACKGROUND Whey protein supplementation may augment resistance exercise-induced increases in muscle strength and mass . Further studies are required to determine whether this effect extends to mobility-limited older adults . The objectives of the study were to compare the effects of whey protein concentrate ( WPC ) supplementation to an isocaloric control on changes in whole-body lean mass , mid-thigh muscle cross-sectional area , muscle strength , and stair-climbing performance in older mobility-limited adults in response to 6 months of resistance training ( RT ) . METHODS Eighty mobility-limited adults aged 70 - 85 years were r and omized to receive WPC ( 40g/day ) or an isocaloric control for 6 months . All participants also completed a progressive high-intensity RT intervention . Sample sizes were calculated based on the primary outcome of change in whole-body lean mass to give 80 % power for a 0.05-level , two-sided test . RESULTS Lean mass increased 1.3 % and 0.6 % in the WPC and control groups , respectively . Muscle cross-sectional area was increased 4.6 % and 2.9 % in the WPC and control groups , respectively , and muscle strength increased 16%-50 % in WPC and control groups . Stair-climbing performance also improved in both groups . However , there were no statistically significant differences in the change in any of these variables between groups . CONCLUSIONS These data suggest that WPC supplementation at this dose does not offer additional benefit to the effects of RT in mobility-limited older adults
