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 .
Long-term exercise and its effect on balance in older, osteoarthritic adults: results from the Fitness, Arthritis, and Seniors Trial (FAST).
OBJECTIVES To examine the effects of 18-month aerobic walking and strength training programs on static postural stability among older adults with knee osteoarthritis . DESIGN R and omized , single-blind , clinical trial of therapeutic exercise . SETTING Both center-based ( university ) and home-based . PARTICIPANTS A cohort of 103 older adults ( age = 60 years ) with knee osteoarthritis who were participants in a large ( n = 439 ) clinical trial and who were r and omly assigned to undergo biomechanical testing . INTERVENTION An 18-month center- ( 3 months ) and home-based ( 15 months ) therapeutic exercise program . The subjects were r and omized to one of three treatment arms : ( 1 ) aerobic walking ; ( 2 ) health education control ; or ( 3 ) weight training . MEASUREMENTS Force platform static balance measures of average length ( Rm ) of the center of pressure ( COP ) , average velocity ( Vel ) of the COP , elliptical area ( Ae ) of the COP , and balance time ( T ) . Measures were made under four conditions : eyes open , double- and single-leg stances and eyes closed , double- and single-leg stances . RESULTS In the eyes closed , double-leg stance condition , both the aerobic and weight training groups demonstrated significantly better sway measures relative to the health education group . The aerobic group also demonstrated better balance in the eyes open , single-leg stance condition . CONCLUSIONS Our results suggest that long-term weight training and aerobic walking programs significantly improve postural sway in older , osteoarthritic adults , thereby decreasing the likelihood of larger postural sway disturbances relative to a control group
