Walking May Prevent Diabetes

The current issue of the Journal of the American Medical Association reports a study of over 1400 participants, led by Elizabeth J. Mayer-Davis of the University of South Carolina in Columbia. Diabetes occurs when the body is insulin deficient and/or becomes impaired in its capacity to use insulin. They studied the relationship between insulin sensitivity, the body's capacity to use insulin, and exercise among subjects ranging from normal in insulin-using capacity to mildly diabetic.
Result: subjects who exercise moderately and regularly were significantly less likely to have impaired insulin-using capacity than sedentary subjects.
