  • Basal rate reductions should be made 60–90 minutes before the onset of exercise and should last until the activity is completed. Prolonged disconnection of the pump or reductions in the basal rate to 0 may result in hyperglycemia. Individuals should test their glucose levels frequently and resume basal insulin delivery or provide bolus delivery if glucose levels are rising toward the hyperglycemic range.
