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 .
Progressive resistance strengthening exercises after stroke: a single-blind randomized controlled trial.
OBJECTIVE To determine the effectiveness of progressive resistance strengthening exercises to improve gross motor function and walking in patients receiving intensive rehabilitation after stroke . DESIGN R and omized controlled trial . SETTING Five inpatient rehabilitation programs affiliated with teaching hospitals . PARTICIPANTS Inclusion criteria included less than 6 months poststroke and recovery of the leg stages 3 to 5 on the Chedoke-McMaster Stroke Assessment ( CMSA ) . INTERVENTIONS Both groups received conventional physical therapy programs . In addition , the experimental group performed 9 lower-extremity progressive resistance exercises 3 times a week for the duration of their stay , whereas the control group did the same exercises and for the same duration but without resistance . MAIN OUTCOME MEASURES The Disability Inventory of the CMSA and the 2-minute walk test ( 2MWT ) at baseline , 4 weeks , discharge , and 6 months after discharge . RESULTS Over the length of stay , the rate of change in the Disability Inventory was.27 points per day in the experimental group and .29 points per day in the control group ; the between-group difference was -.02 points per day ( 95 % confidence interval [ CI ] , -.10 to.06 ; P=.62 ) . At discharge , the rate of change in the 2MWT was -.01 m in the experimental group and .15 m in the control group ; the between-group difference was -.16 m ( 95 % CI , -.37 to.05 ; P=.14 ) . CONCLUSIONS Progressive resistance strengthening exercises as applied in our study were not effective when compared with the same exercises given without resistance
