Physical exercise and juvenile diabetes--summary and conclusions.

The various metabolic effects of physical exercise in ketotic diabetics, non-ketotic diabetics and non-diabetics are summarized. A favorable metabolic effect is only observed during optimal insulin administration, while in ketotic diabetics exercise may aggravate the metabolic situation. The use of exercise as a tool in the routine treatment of young diabetics is described. Activity-produced hypoglycemia should be prevented through an adequate food intake and through patient education. Regular exercise may postpone the appearance of diabetic microangiopathy.
