A Quick Sprint to Prevent Lows
Exercise normally increases the risk that blood glucose will dip too low in insulin users, but a small study found that a short sprint before or after a workout may help prevent hypoglycemia. After a 10-second sprint, blood glucose in eight people with type 1 diabetes increased an average of 22 mg/dl within 30 minutes. The researchers say the rise resulted from a slower rate of glucose disappearance from the blood, rather than a sudden influx of glucose into the blood. They also say that changes in hormone levels prompted by the short sprint may explain the modest rise in blood glucose.
