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 .

Exercise: effects on physical functional performance in independent older adults.
BACKGROUND Age-related loss in physiologic capacities contributes to the decline in physical function in the elderly population . Despite the beneficial effects of exercise interventions on maximal physiologic capacity measures , the functional benefits have not been shown in independently living older adults . The objective of this study was to evaluate exercise in independent older adults for significant and meaningful improvements in physical function , not detected by commonly used measures of physical function . METHODS In a r and omized controlled study , 49 independently living men and women were assigned to either a nonexercise control group ( Control ; n = 26 ) or an exercise training group ( Exercise ; n = 23 ) . Participants ( age = 76+/-4 ) in good general health were recruited from retirement communities or apartments . The combined endurance and strength training was performed at 75 % to 80 % intensity ; the groups met 3 times/week for 6 months of supervised sessions . Outcome measures included physical capacity , health status , and physical function using a newly developed performance test -- the Continuous Scale-Physical Functional Performance test ( CS-PFP ) . RESULTS Compared to the Control group , the Exercise group showed significant increases in maximal oxygen consumption ( 11 % ) and muscle strength ( 33 % ) . No significant differences were found between groups for changes in the Sickness Impact Profile , SF-36 scales , or the 6-minute walk . However , the CS-PFP score improved significantly in the Exercise group ( 14 % , effect size 0.80 ) . CONCLUSIONS Independent older adults gain meaningful functional benefits from several months of exercise training . The public health importance of physical activity may relate not just to its role in preventing decline , but also to its role in enhancing physical function
