4-6-2 Reducing Hypoglycaemia During Exercise

Practical insulin and fueling strategies to prevent low blood glucose in sport

Physical activity increases insulin sensitivity and muscle glucose uptake, which can lead to hypoglycaemia in people living with type 1 diabetes. The risk depends on insulin on board, exercise intensity, duration, and timing. The following strategies help reduce low blood glucose during and after exercise. 

Reduce Pre-Exercise Bolus by 50–70%

Pre-Exercise Carbohydrate Intake

Repeated Small Carbohydrate Doses During Exercise

Reduce Basal Insulin by 50–80%

Set Higher Temporary Glucose Target (Closed-Loop Users)

Reduce Post-Exercise Basal by 20% for 6 Hours

Avoid Unnecessary Pump Suspension

Use Short Sprints During Aerobic Exercise

Caffeine Before Exercise
