Serious adverse events were rare , and no serious events were reported to be directly related to the exercise programme .
This review provides evidence that PRT is an effective intervention for improving physical functioning in  older people , including improving strength and the performance of some simple and complex activities .
BACKGROUND Muscle weakness in old age is associated with physical function decline .
Progressive resistance strength training ( PRT ) exercises are design ed to increase strength .
OBJECTIVES To assess the effects of PRT on older people and identify adverse events .
Once weekly combined resistance and cardiovascular training in healthy older men.
PURPOSE To compare the effects of the 16-wk training period ( 2 d.wk(-1 ) ) of resistance training alone ( S ) , endurance training alone ( E ) , or combined resistance ( once weekly ) and endurance ( once weekly ) training ( SE ) on muscle mass , maximal strength and power of the leg and arm extensor muscles , and maximal workload ( Wmax ) by using a incremental cycling test in older men . METHODS Thirty-one healthy men ( 65 - 74 yr ) were divided into three treatment groups to train 2x wk(-1 ) for 16 wk : S ( N = 10 ) , E ( N = 11 ) , or SE ( N = 10 ; 1x wk(-1 ) S + 1x wk(-1 ) E ) . The subjects were tested at 8-wk intervals ( i.e. , weeks 8 and 16 ) . RESULTS There were no significant differences between  S- and SE-induced muscle hypertrophy ( 11 % and 11 % ) and maximal strength ( 41 % and 38 % ) gains of the legs as well as between E- and SE-induced Wmax ( 28 % and 23 % ) gains . The increase in arm strength in S ( 36 % ) was greater than that recorded in SE ( 22 % ) and greater than that recorded in E ( 0 % ) . CONCLUSIONS Prolonged combined resistance and endurance training in older men seemed to lead to similar gains in muscle mass , maximal strength , and power of the legs as resistance training alone and to similar gains in maximal peak power output measured in an incremental cycling test as endurance training alone . These findings may have an effect on how resistance exercise is prescribed to older adults
