Researchers recruited 17 patients with type 1 diabetes using continuous subcutaneous insulin infusion, mean age of 31, and found that those who had a 50% to 80% basal rate reduction 90 minutes before exercise reduced their hypoglycemia risk and improved their open-loop glucose control, compared with individuals who had pump suspension at the start of exercise. The findings in Diabetes Care also revealed that glucose levels after eating a standard meal after exercise increased among those in the 50% basal rate reduction and pump suspension groups but not in the 80% basal rate reduction group.
