Summary

Despite the established health benefits conveyed by physical activity for people with type 1 diabetes (T1D), participation rates remain low, with fear of hypoglycaemia, lack of freedom to engage in unplanned activities, and uncertainty in making appropriate adjustments to insulin and nutritional therapy reported as the leading barriers to regular exercise engagement. Indeed, the synergistic glucose lowering effects of peripheral hyperinsulinaemia and exercising muscle tissue accentuate the risk of exercise-related hypoglycaemia for individuals with T1D, particularly if performed post-prandially. Hence, the introduction of commercially available artificial pancreas systems, also known as ''advanced hybrid-closed-loop'' (AHCL) systems, that regulate insulin rates with minimal user interaction constitute compelling therapeutic aids with clinically relevant potential. Nevertheless, we know little about their safe and efficacious integration around dynamic physical exercise. Nor do we know how alterations in carbohydrate fueling strategies around exercise effect subsequent glucose trends.

This study aims to 1) compare the efficacy of an AHCL system versus usual care insulin pump therapy, with carbohydrates taken before or during exercise, in optimising TIR around dynamic physical exercise and 2) explore the influence of carbohydrate intake before versus during exercise on the metabolomic, hormonal and physiological responses to exercise.
