Reduction of insulin basal rate 40 minutes prior to exercise for Diabetes

It has been reported that insulin basal rate reduction initiated at exercise onset can reduce the hypoglycemic risk during exercise. However, another potentially more efficient strategy to prevent exercise-induced hypoglycemia could be to reduce insulin basal rate a certain time prior to exercise. The objective of this study will be to compare the efficacy of two strategies to prevent exercise-induced hypoglycemia during a 60-minute exercise at moderate intensity: 1) reduce insulin basal rate 40 minutes prior to exercise; 2) reduce insulin basal rate 90 minutes prior to exercise.
