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 .
Increased Velocity Exercise Specific to Task (InVEST) training: a pilot study exploring effects on leg power, balance, and mobility in community-dwelling older women.
OBJECTIVES To evaluate a dynamic form of weighted vest exercise suitable for home use and design ed to enhance muscle power , balance , and mobility . DESIGN A single-blind , r and omized , controlled trial . SETTING Outpatient exercise research facility situated within an academic long-term care center . PARTICIPANTS Twenty-one community-dwelling women aged 70 and older with a Short Physical Performance Battery ( SPPB ) score between 4 and 10 ( out of 12 ) . INTERVENTIONS Subjects were r and omized into a progressive resistance-training program using weighted vests for resistance with exercises design ed to be specific to mobility tasks and have a component performed at the fastest possible velocity ( Increased Velocity Exercise Specific to Task ( InVEST ) , n=11 ) or a control exercise group ( control , n=10 ) , which performed slow-velocity , low-resistance exercise . Both groups exercised three times a week for 12 weeks . MEASUREMENTS Changes in muscle power , balance , and physical performance were compared . RESULTS In comparison to control group , InVEST group manifested significant improvements ( P<.05 ) in leg power across measurements obtained at 75 % to 90 % of the one-repetition maximum . Both groups demonstrated significant improvements in chair st and and SPPB score from baseline , and the InVEST group showed significant improvements in gait speed and chair st and from baseline ( P<.05 ) . InVEST produced significantly greater changes in chair st and time than control ( P<.05 ) . CONCLUSION InVEST training appears be an effective means of enhancing leg power and chair rise in this population and is worthy of further investigation as a means of enhancing balance and mobility
