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 .
Effects of High-Speed Power Training on Muscle Performance and Braking Speed in Older Adults
We examined whether high-speed power training ( HSPT )  improved muscle performance and braking speed using a driving simulator . 72 older adults ( 22 m , 50 f ; age = 70.6 ± 7.3 yrs ) were r and omized to HSPT at 40 % one-repetition maximum ( 1RM ) ( HSPT : n = 25 ; 3 sets of 12–14 repetitions ) , slow-speed strength training at 80%1RM ( SSST : n = 25 ; 3 sets of 8–10 repetitions ) , or control ( CON : n = 22 ; stretching ) 3 times/week for 12 weeks . Leg press and knee extension peak power , peak power velocity , peak power force/torque , and braking speed were obtained at baseline and 12 weeks . HSPT  increased peak power and peak power velocity across a range of external resistances ( 40–90 % 1RM ; P < 0.05 ) and improved braking speed ( P < 0.05 ) . Work was similar between groups , but perceived exertion was lower in HSPT ( P < 0.05 ) . Thus , the less strenuous HSPT exerted a broader training effect and improved braking speed compared to SSST
