Effects of progressive resistance training on body composition in frail older adults: results of a randomized, controlled trial.
BACKGROUND Progressive resistance exercise training ( PRT ) has been shown to increase muscle strength and fat-free mass ( FFM ) in elderly persons . Limited information is available regarding the effects of PRT on lean and fat mass in frail elderly persons . METHODS Ninety-one community-dwelling sedentary men and women , 78 years and older with physical frailty ( defined using st and ardized objective criteria ) were enrolled in a 9-month trial of exercise training ( ET ) . Physical frailty was defined as having 2 of the 3 following criteria : modified Physical Performance Test score between 18 and 32 , peak aerobic power between 10 and 18 ml/kg/min , or self-report of difficulty or assistance with two instrumental activities of daily living or one basic activity of daily living . Participants were r and omly assigned to either a control ( CTL ) group that performed a low intensity home exercise program or a supervised ET group that performed 3 months of low intensity exercise and 3 months of PRT . RESULTS After completion of PRT , ET participants had greater improvements than did CTL participants in maximal voluntary force production for knee extension ( mean Delta + 5.3 + /- 13 ft/lb vs + 1.1 + /- 11 ft/lb , p = .05 ) , measured using isokinetic dynamometry . Total body FFM ( measured using dual energy x-ray absorptiometry ) increased in the ET group , but not in the CTL group ( mean Delta + 0.84 + /- 1.4 kg vs + 0.01 + /- 1.5 kg , p = .005 ) . Total , trunk , intra-abdominal , and subcutaneous fat mass ( measured using dual energy x-ray absorptiometry and (1)H-magnetic resonance imaging ) did not change in response to PRT . CONCLUSIONS Three months of supervised PRT induced improvements in maximal voluntary thigh muscle strength and whole body FFM in frail , community-dwelling elderly women and men . This supervised exercise program may not be sufficient to reduce whole-body or intra-abdominal fat area in this population
