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 a group-based exercise program on functional abilities in frail older women after hospital discharge
Background and aims : An acute illness may place older frail people at increased risk of losing independence in functional abilities . Physical exercise may reduce the risk by improving muscle strength and balance . However , the effects of physical training on functional abilities have not been studied among frail , very old people recovering from an acute illness . The aim of this study was to determine the effects of a group-based exercise program on their ability to carry out self-care ( ADL ) and instrumental activities ( IADL ) relevant to daily life after discharge from hospital . Methods : This r and omized controlled trial examined 68 community-dwelling women aged 75 years or older ( mean age 83.0 , SD 3.9 ) who were hospitalized due to an acute illness , and were mobility-impaired at admission . Participants were recruited from the geriatric ward of a primary -care health-center hospital , and were r and omized into group-based strength training ( n=34 ) and control ( n=34 ) groups . The 10-week group-based intervention included strength training and functional exercises . The control group received instructions for a home exercise training program , including functional exercises but no further encouragement to exercise . The level of independence in ADL and IADL was evaluated , using a 13-item scale with stepwise grading from fully independent to fully dependent . Measurements took place immediately before and after the intervention , and three and nine months later . Results : The intervention did not have any significant main effect ( p=0.407 ) , nor was there any significant interaction between follow-up time and intervention ( p=0.854 ) . Conclusions : The multi-component outpatient strength training program did not improve autonomy in expert-evaluated ADL/IADL functions
