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 .
Effect of power-training intensity on the contribution of force and velocity to peak power in older adults.
OBJECTIVE To determine the effect of training intensity on the contributions of force and velocity to improvements in peak power ( PP ) after explosive resistance training in older adults . METHODS 112 healthy older adults ( 69 + /- 6 yr ) were r and omized to explosive resistance training at 20 % ( G20 ) , 50 % ( G50 ) , or 80 % ( G80 ) maximal strength ( 1-repetition maximum ) for 8 - 12 wk ( twice weekly , 5 exercises , 3 sets of 8 explosive concentric/slow eccentric repetitions ) using pneumatic resistance machines or a nontraining control group ( CON ) . RESULTS Force at peak power ( FPP ) increased significantly and similarly among training groups compared with CON . Velocity at peak power ( VPP ) did not improve significantly and remained similar between all groups . Force contributed significantly more to PP production in G80 and G50 than in CON . The change in PP was independently predicted by changes in fat-free mass in G80 and by changes in both FPP and VPP in G50 and G20 . CONCLUSION Explosive resistance training in older adults results in the ability to produce higher PP outputs with heavier loads without loss of movement velocity . Moderate- to high-intensity training induced a greater relative contribution of force to PP production in this cohort
