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 .
Can elderly patients who have had a hip fracture perform moderate- to high-intensity exercise at home?
BACKGROUND AND PURPOSE The majority of patients after a hip fracture do not return to prefracture functional status . Depression has been shown to affect recovery . Although exercise can reduce impairments , access issues limit elderly people from participating in facility-based programs . The primary purpose of this study was to determine the effects and feasibility of a home exercise program of moderate- or high-intensity exercise . A secondary purpose was to explore the relationship of depression and physical recovery . SUBJECTS Thirty-three elderly people ( 24 women , 9 men ; mean = 78.6 years of age , SD = 6.8 , range = 64 - 89 ) who had completed a regimen of physical therapy following hip fracture participated in the study . Subjects were r and omly assigned to a resistance training group , an aerobic training group , or a control group . METHODS Subjects were tested before and upon completion of the exercise trial . Isometric lower-extremity force , 6-minute-walk distance , free gait speed , mental status , and physical function were measured . Each exercise session was supervised by a physical therapist , and subjects received 20 visits over 12 weeks . The control group received biweekly mailings . The resistance training group performed 3 sets of 8 repetitions at the 8-repetition maximum intensity using a portable progressive resistance exercise machine . The aerobic training group performed activities that increased heart rate 65 % to 75 % of their age-predicted maximum for 20 continuous minutes . RESULTS Resistance and aerobic training were performed without apparent adverse effects , and adherence was 98 % . All groups improved in distance walked , force produced , gait speed , and physical function . Isometric force improved to a greater extent in the intervention groups than in the control group . Depressive symptoms interacted with treatment group in explaining the outcomes of 6-minute-walk distance and gait speed . DISCUSSION AND CONCLUSION High-intensity exercise performed in the home is feasible for people with hip fracture . Larger sample sizes may be necessary to determine whether the exercise regimen is effective in reducing impairments and improving function . Depression may play a role in the level of improvement attained
