Conclusions This review provides evidence that RT has a moderate positive effect on self-reported disability/function  in old people with or at risk for disability .
The effects are strongly associated with effects on objective measures of lower body functional capacity
Background Self-reported disability has a strong negative impact on older people ’s  quality of life and is often associated with the need for assistance and health care services .
Resistance training ( RT ) has been repeatedly shown to improve muscle function ( e.g. strength ) and functional capacity ( e.g. gait speed , chair-rise ) in older adults with functional limitations .
Nevertheless , it is unclear whether such objective ly assessed improvements translate into a reduction in self-reported disability .
Objectives To assess : i ) whether and to what extent RT interventions have an effect on self-reported disability in older adults ( ≥65 years ) with functional limitations or disability ; and ii ) whether the effects on self-reported disability are associated with changes in objective measures of muscle strength and functional capacity across studies .
The effect of strength and endurance training on gait, balance, fall risk, and health services use in community-living older adults.
BACKGROUND The study tested the effect of strength and endurance training on gait , balance , physical health status , fall risk , and  health services use in older adults . METHODS The study was a single-blinded , r and omized controlled trial with intention-to-treat analysis . Adults ( n = 105 ) age 68 - 85 with at least mild deficits in strength and balance were selected from a r and om sample of enrollees in a health maintenance organization . The intervention was supervised exercise ( 1-h sessions , three per week , for 24 - 26 weeks ) , followed by self-supervised exercise . Exercise groups included strength training using weight machines ( n = 25 ) , endurance training using bicycles ( n = 25 ) , and strength and endurance training ( n = 25 ) . Study outcomes included gait tests , balance tests , physical health status measures , self-reported falls ( up to 25 months of follow-up ) , and inpatient and outpatient use and costs . RESULTS There were no effects of exercise on gait , balance , or physical health status . Exercise had a protective effect on risk of falling ( relative hazard = .53 , 95 % CI = .30-.91 ) . Between 7 and 18 months after r and omization , control subjects had more outpatient clinic visits ( p < .06 ) and were more likely to sustain hospital costs over $ 5000 ( p < .05 ) . CONCLUSIONS Exercise may have beneficial effects on fall rates and health care use in some subgroups of older adults . In community-living adults with mainly mild impairments in gait , balance , and physical health status , short-term exercise may not have a restorative effect on these impairments
