Acute Exercise May Help Type 2 Diabetics Control Blood Sugar

Bouts of exercise reduced hyperglycemia by 39 percent in 24-hour period

FRIDAY, Dec. 29 (HealthDay News) -- Acute bouts of exercise can help patients with insulin-treated type 2 diabetes control their blood sugar levels for at least 24 hours, according to a report in the December issue of Medicine & Science in Sports & Exercise.

Stephan F. Praet, M.D., of Maastricht University in the Netherlands, and colleagues used continuous subcutaneous glucose monitoring to study the effects of acute bouts of exercise on 24-hour blood glucose excursions under free-living conditions in type 2 diabetics taking insulin.

The researchers found that hyperglycemic excursions were reduced by 39 percent during a 24-hour period after exercise while average glucose concentrations before and after exercise did not differ. Mean glucose concentrations and periods of hyperglycemia correlated strongly with baseline blood HbA1c concentrations.

"Daily, moderate-intensity exercise represents a valuable adjunct to the therapeutic arsenal to improve glycemic control in a subpopulation of type 2 diabetes patients, which have proven difficult to manage," the authors conclude.
