Exercise and aging. Issues for the practitioner.

The elderly present the health care system with a number of challenges, the most important of which centers on the declining functional capacity associated with aging. It remains to be clarified the degree to which these changes are related to the interactions among aging, disease, illness, injury, lifestyle, genetics, and other variables. While these issues are being clarified, however, it is clear that a well-designed exercise program that is of low to moderate intensity may be the single, most cost-effective means of maintaining function. The exercise program needs to be goal-oriented and goal congruent, yet it must be individualized to account for existing impairments. General guidelines, such as those in Table 7, may be useful in maintaining a perspective on the regimen. Regardless of the degree of functional limitations, all elderly can derive some benefit from engaging in an exercise program. The emphasis of any regimen should be on quality-of-life issues, such as improving flexibility, strength, and mobility. For the vast majority of elderly, a simple walking program is probably the safest, most effective form of activity.
