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 .
Effects of exercise training on frailty in community-dwelling older adults: results of a randomized, controlled trial.
OBJECTIVES Although deficits in skeletal muscle strength , gait , balance , and oxygen uptake are potentially reversible causes of frailty , the efficacy of exercise in reversing frailty in community-dwelling older adults has not been proven . The aim of this study was to determine the effects of intensive exercise training ( ET ) on measures of physical frailty in older community-dwelling men and women . DESIGN R and omized controlled trial . SETTING Medical school research center . PARTICIPANTS One hundred fifteen sedentary men and women ( mean age + /- st and ard deviation = 83 + /- 4 ) with mild to moderate physical frailty , as defined by two of the following three criteria : Modified Physical Performance Test ( modified PPT ) score between 18 and 32 , peak oxygen uptake ( VO2 peak ) between 10 and 18 mL/kg/min , and self-report of difficulty or assistance with one basic activity of daily living ( ADL ) , or two instrumental ADLs . INTERVENTION Participants were r and omly assigned to a control group that performed a 9-month low-intensity home exercise program ( control ) or an exercise-training program ( ET ) . The control intervention primarily consisted of flexibility exercises . ET began with 3 months of flexibility , light-resistance , and balance training . During the next 3 months , resistance training was added , and , during the next 3 months , endurance training was added . MEASUREMENTS Modified PPT score , VO2 peak , performance of ADLs as measured by the Older Americans Re sources and Services instrument , and the Functional Status Question naire ( FSQ ) . RESULTS ET result ed in significantly greater improvements than home exercise in three of the four primary outcome measures . Adjusted 95 % confidence bounds on the magnitude of improvement in the ET group compared with the control group were 1.0 to 5.2 points for the modified PPT score , 0.9 to 3.6 mL/kg/min for VO2 peak , and 1.6 to 4.9 points for the FSQ score . CONCLUSIONS Our results show that intensive ET can improve measures of physical function and pre clinical disability in older adults who have impairments in physical performance and oxygen uptake and are not taking hormone replacement therapy better than a low-intensity home exercise program
