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 .
Multicomponent exercises including muscle power training enhance muscle mass, power output, and functional outcomes in institutionalized frail nonagenarians
This r and omized controlled trial examined the effects of multicomponent training on muscle power output , muscle mass , and muscle tissue attenuation ; the risk of falls ; and functional outcomes in frail nonagenarians . Twenty-four elderly ( 91.9 ± 4.1 years old ) were r and omized into intervention or control group . The intervention group performed a twice-weekly , 12-week multicomponent exercise program composed of muscle power training ( 8–10 repetitions , 40–60 % of the one-repetition maximum ) combined with balance and gait retraining .  Strength and power tests were performed on the upper and lower limbs . Gait velocity was assessed using the 5-m habitual gait and the time-up- and -go ( TUG ) tests with and without dual-task performance . Balance was assessed using the FICSIT-4 tests . The ability to rise from a chair test was assessed , and data on the incidence and risk of falls were assessed using question naires . Functional status was assessed before measurements with the Barthel Index . Midthigh lower extremity muscle mass and muscle fat infiltration were assessed using computed tomography . The intervention group showed significantly improved TUG with single and dual tasks , rise from a chair and balance performance ( P < 0.01 ) , and a reduced incidence of falls . In addition , the intervention group showed enhanced muscle power and strength ( P < 0.01 ) . Moreover , there were significant increases in the total and high-density muscle cross-sectional area in the intervention group . The control group significantly reduced strength and functional outcomes . Routine multicomponent exercise intervention should be prescribed to nonagenarians because overall physical outcomes are improved in this population
