Prescribing exercise for the adult with diabetes.

Exercise is a useful tool in the management of diabetes, contributing to cardiovascular and psychosocial well-being, weight control, and, in noninsulin-dependent diabetes, improvement of blood glucose levels. An optimal exercise program should be based on a comprehensive assessment and include a written prescription for the type, frequency, duration, and intensity of exercise. This article includes guidelines for writing exercise prescriptions as well as techniques for monitoring its effects. A discussion of risks related to diabetes provides safety guidelines.
