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 .
Physical performance measures in the clinical setting.
OBJECTIVES To assess the ability of gait speed alone and a three-item lower extremity performance battery to predict 12-month rates of hospitalization , decline in health , and decline in function in primary care setting s serving older adults . DESIGN Prospect i ve cohort study . SETTING Primary care programs of a Medicare health maintenance organization ( HMO ) and Veterans Affairs ( VA ) system . PARTICIPANTS Four hundred eighty-seven persons aged 65 and older . MEASUREMENTS  Lower extremity performance Established Population for Epidemiologic Studies of the Elderly ( EPESE ) battery including  gait speed , chair st and s , and t and em balance tests ; demographics ; health care use ; health status ; functional status ; probability of repeated admission scale ( Pra ) ; and primary physician 's hospitalization risk estimate . RESULTS Veterans had poorer health and higher use than HMO members . Gait speed alone and the EPESE battery predicted hospitalization ; 41 % ( 21/51 ) of slow walkers ( gait speed < 0.6 m/s ) were hospitalized at least once , compared with 26 % ( 70/266 ) of intermediate walkers ( 0.6 - 1.0 m/s ) and 11 % ( 15/136 ) of fast walkers ( > 1.0 m/s ) ( P < .0001 ) . The relationship was stronger in the HMO than in the VA . Both performance measures remained independent predictors after accounting for Pra . The EPESE battery was superior to gait speed when both Pra and primary physician 's risk estimate were included . Both performance measures predicted decline in function and health status in both health systems . Performance measures , alone or in combination with self-report measures , were more able to predict outcomes than self-report alone . CONCLUSION Gait speed and a physical performance battery are brief , quantitative estimates of future risk for hospitalization and decline in health and function in clinical population s of older adults . Physical performance measures might serve as easily accessible " vital signs " to screen older adults in clinical setting
