The Influence of Muscular Exercise on Blood Sugar Concentrations.

The beneficial effects of exercise on certain types of diabetes mellitus have long been recognized. Occasionally a young and active diabetic, with a stable glycemia, controlled by diet and insulin, develops severe and sometimes prolonged insulin reactions following participation in strenuous sports; while other young and equally active diabetics, with an unstable glycemia, find participation in active sports a burden, accompanied by glycosuria and general malaise. The effect of exercise on glycosuria and glycemia was determined in twelve cases of diabetes mellitus treated with insulin; in four of diabetes mellitus treated without insulin; in three of renal glycosuria; in two of hypotension; in one patient with glycosuria of pregnancy, another with obesity, a third with epilepsy, and in three normal individuals.
