Benefits of exercise for older adults. A review of existing evidence and current recommendations for the general population.

Currently available data are of variable rigor and from a variety of sources, yet they do support several conclusions about the potential value of exercise for whole groups of elderly persons. (1) Exercise of moderate intensity may benefit many elderly persons in numerous and complementary ways (e.g., cardiovascular status, fracture risk, functional ability, and mental processing). (2) There are few complications associated with such increases in activity. Indeed, a remarkable aspect of research on exercise in the elderly has been the virtual absence of reports of serious cardiovascular or musculoskeletal complications in any published trials. Cardiac rehabilitation programs, enrolling many persons over 65 years of age with known coronary artery disease, also report few major cardiovascular complications. Thus, exercise should be viewed as safe for most older adults. (3) Exercise in the elderly probably needs to be tailored, and when possible, individualized, with the specific objectives of the person or group in mind. Some benefits are probably related to the intensity of exercise (e.g., cardiovascular disease), others due to the type of exercise (weight-bearing versus nonweight-bearing for osteoporosis, or racket sports for hand-eye coordination), and still others possibly relate to the setting in which exercise occurs (social-psychological benefits). (4) The authors believe the known physiologic effects of exercise on age-related changes and existing clinical research support the general notion that vigorous weight-bearing exercises such as walking are the safest, cheapest, easiest, and most widely beneficial for the average senior. (5) Research has yet to define good ways by which to stimulate large numbers of sedentary elderly persons to exercise regularly. The potential and complementary benefits appear to be great enough to justify widespread efforts at the community and individual level, however.

Participation of older adults in health programs and research: a critical review of the literature.

This collection of five papers evaluates the participation of older adults in clinical trials, health promotion/disease prevention initiatives, and health programs designed to maintain or improve the functioning of chronically ill older adults. Understanding the willingness or unwillingness of older adults to participate in these programs is critical to the development and implementation of health programs and policies for this population. In this introductory paper we briefly review illustrative literature to provide both an overview of the participation of older adults in health programs as well as background information relevant to the symposium papers.

Factors associated with regular aerobic exercise in an elderly population.

BACKGROUND: Little is known regarding the characteristics of elderly persons who do not regularly exercise. This lack of knowledge limits the design and marketing of exercise programs to persons who could benefit from regular exercise. METHODS: We compared characteristics of regular exercisers and nonexercisers among 561 randomly selected persons aged 65 years and older who were enrollees of a health maintenance organization. Baseline data were obtained on sociodemographics, health attitudes, and medical conditions. RESULTS: Of the 561 persons studied, 192 (34 percent) were regular exercisers. Exercisers were slightly younger than nonexercisers and reported more positive health perceptions. Nonexercisers tended to report lower incomes and lower educational levels than did exercisers. Exercisers were less likely to report hypertension, arthritis, or two or more of the following medical conditions: heart disease, hypertension, arthritis, and emphysema (odds ratio 0.49; confidence interval 0.28 to 0.86). Sex differences were present. In logistic regression analysis, higher reported income, better perception of current health, and fewer than two medical conditions were associated with regular exercise status. CONCLUSIONS: Specific characteristics are present in persons who regularly exercise compared with those who do not. These findings may prove useful in understanding the dynamics of exercise behavior in this age group and in designing exercise interventions for this population.
