Reducing Risks and Improving Glucose Control During Extended Exercise in Youth With T1DM: The AP Ski Camp

The object of this study is to evaluate the Closed-Loop Control (CLC) in an environment where muscle glycogen is systematically depleted, glucose uptake systematically increased, and meal sizes are naturally larger than normal: a week of camp at high altitude, with the concomitant variable of oxygen consumption that this environment involves; during the winter, that will expose and challenge the different components of the system during cold temperatures, and with twice daily practice of physical activity designed to deplete glycogen reserves such as skiing. This proposal aims to demonstrate the superiority of the CLC, also known as Artificial Pancreas (AP), compared to the state-of-the art system available on the market: Sensor-augmented pump (SAP). This system has shown to diminish hypoglycemic events by setting the alarms on the continues glucose monitor (CGM) and taken action, such as performing self-monitoring blood glucose (SMBG) and treating if it is confirm to be low.
