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 .
The relationship between leg power and physical performance in mobility-limited older people.
OBJECTIVES The purpose of this study was to assess the influence of leg power and leg strength on the physical performance of community-dwelling mobility-limited older people . DESIGN Cross-sectional analysis of baseline data from a 12-week r and omized controlled exercise-intervention study . SETTING Exercise laboratory within the Department of Health Science of an urban university . PARTICIPANTS Forty-five community-dwelling mobility-limited people ( 34 women , 11 men ) , aged 65 to 83 . MEASUREMENTS Health status , depression , cognition , physical activity , and falls efficacy ; physiological measures of lower extremity strength and power ; and measures of physical performance . RESULTS Through bivariate analyses , leg power  was significantly associated with physical performance as measured by stair-climb time , chair-st and time , t and em gait , habitual gait , maximal gait , and the short physical performance battery describing between 12 % and 45 % of the variance ( R2 ) . Although leg power and leg strength were greatly correlated ( r = .89 ) in a comparison of bivariate analyses of strength or power with physical performance , leg power modeled up to 8 % more of the variance for five of six physical performance measures . Despite limitations in sample size , it appeared that , through quadratic modeling , the influence of leg power on physical performance was curvilinear . Using separate multivariate analyses , partial R2 values for leg power and leg strength were compared , demonstrating that leg power accounted for 2 % to 8 % more of the variance with all measures of physical performance . CONCLUSION Leg power  is an important factor influencing the physical performance of mobility-limited older people . Although related to strength , it is a separate attribute that may exert a greater influence on physical performance . These findings have important implication s for clinicians practicing geriatric rehabilitation
