Exercise in the prevention and treatment of chronic disorders

The Defense Women's Health Research Initiative commissioned a review of the literature of women's health issues. This was performed and published by the Institute of Medicine. In this publication it was noted that health promotion and disease prevention in women should be an area of high priority for military medicine. This article details some of the ways in which exercise may make substantial contributions to this goal. The available evidence indicates that there is an inverse association between physical activity and a variety of chronic diseases. Moreover, physical activity appears to influence psychological well-being. Aerobic exercise is the mode most frequently studied, and appears to confer positive changes, but other forms of exercise may prove to be equally beneficial. However, the appropriate duration, intensity, and frequency of the exercise have not been determined for any of these chronic health problems and must be considered before global recommendations can be offered. Efforts to promote physical activity within the community, schools, and homes must be initiated to achieve the goals set forth in Healthy People 2000, so the health of our women can improve. Future studies will be required to identify mechanisms whereby physical activity confers benefit.
