This is a non-interventional, prospective, multi-site study conducted in France among adults with type 1 diabetes mellitus using automated insulin delivery (AID) systems and engaging in at least two exercise sessions per week, each lasting at least 30 minutes. The main objective of this study is to describe the glycemic control of athletic participants with type 1 diabetes mellitus who use an insulin pump with AID and engage in physical exercise under real-life conditions. Two physician data collection time points are planned: the first occurs at baseline and includes demographic and clinical data, glycemic control during the month preceding inclusion, diabetes management, and information on usual physical exercise (duration, type, sport practiced, competition participation, and adherence to a specific diet). The second occurs at 1-month follow-up and involves downloading insulin pump and glucose sensor data, covering the period from 15 days before the first reported exercise session to 15 days after the last session. During the 1-month study period, participants will complete a paper logbook after each exercise session to document information such as the type of exercise, self-reported intensity using the modified Borg scale and the WHO physical activity intensity scale, duration, system adjustments, dietary intake, occurrence of hypoglycemia and associated symptoms, snacks consumed, and treatments administered for hypoglycemia.
