MUSCULAR FITNESS - EASING THE BURDEN OF DISABILITY FOR ELDERLY ADULTS

The U.S. Department of Health and Human Services (1990) has specified as a key objective the reduction of disability in the performance of a ctivities of daily living (ADL) for persons over the age of 65 years. Many ADL involve combinations of muscular strength, muscular endurance , and flexibility, three components that together have been referred t o as ''muscular fitness.'' The capacity of the elderly to remain funct ionally independent, therefore, may depend less on cardiovascular fitn ess, which has traditionally been the focus of health related fitness research, than on these components of muscular fitness. This review ad dresses the issue of muscular fitness and disability in the elderly by considering three questions: Is muscular fitness associated with ADL performance? Can muscular fitness be improved with exercise training? Do improvements in muscular fitness improve ADL performance? Answers t o these questions will have important implications for future research and program implementation. Although initial findings are promising, more data are needed on the effect of muscular fitness on functional i ndependence and quality of life in the elderly.
