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 .
Impact of the fit and strong intervention on older adults with osteoarthritis.
PURPOSE This study assessed the impact of a low cost , multicomponent physical activity intervention for older adults with lower extremity osteoarthritis . DESIGN AND METHODS A r and omized controlled trial compared the effects of a facility-based multiple-component training program followed by home-based adherence  ( n = 80 ) to a  wait list control group ( n = 70 ) . Assessment s were conducted at baseline and at 2 and 6 months following r and omization . The training program consisted of range of motion , resistance training , aerobic walking , and education-group problem solving regarding self-efficacy for exercise and exercise adherence . All training group participants developed individualized plans for posttraining adherence . RESULTS Relative to the persons in the control group , individuals who participated in the exercise program experienced a statistically significant improvement in exercise efficacy , a 48.5 % increase in exercise adherence , and a 13.3 % increase in 6-min distance walk that were accompanied by significant decreases in lower extremity stiffness at 2 and 6 months . Program participants also experienced a significant decrease in lower extremity pain and a borderline significant improvement in efficacy to adhere to exercise over time at 6 months ( p = .052 ) . In contrast , persons in the control group deteriorated over time on the efficacy and adherence measures and showed no change on the other measures . No adverse health effects were encountered . IMPLICATION S These benefits indicate that this low-cost intervention may hold great promise as one of a growing number of public health intervention strategies for older adults in the United States with osteoarthritis
