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 .
Task-oriented progressive resistance strength training improves muscle strength and functional performance in individuals with stroke
Objective : To examine the effectiveness of task-oriented progressive resistance strength training on lower extremity strength and functional performance in chronic stroke subjects . Design : Single-blind , r and omized controlled trial . Setting : Medical centre and district hospital . Subjects : Forty-eight subjects at least one year post stroke . Interventions : Participants r and omly allocated to two groups , control  ( n-/24 ) and experimental  ( n-/24 ) . Subjects in the control group did not receive any rehabilitation training . Subjects in the experimental group were put on a four-week task-oriented progressive resistance strength training . Main measures : Lower extremity muscle strength , gait velocity , cadence , stride length , six-minute walk test , step test , and timed up and go test . Results : Muscle strength significantly improved in the experimental group for strong side muscle groups ( ranged from 23.9 % to 36.5 % ) and paretic side muscle groups ( ranged from 10.1 % to 77.9 % ) . In the control group muscle strength changes ranged from 6.7 % gain to 11.2 % decline . The experimental group showed significant improvement in all selected measures of functional performance except for the step test . In the control group , the number of repetitions of the step test significantly decreased ( -20.3 % ) with no change in other functional tests . There was a significant difference between groups for muscle strength and all functional measures . The strength gain was significantly associated with gain in the functional tests . Conclusions : The task-oriented progressive resistance strength training programme could improve lower extremity muscle strength in individuals with chronic stroke and could carry over into improvement in functional abilities
