Brief summary: Every person with type 1 diabetes needs personalized advice to integrate physical activity into daily diabetes management. The purpose of this study is to collect data on food intake, physical activity, glucose levels and insulin delivery from people with type 1 diabetes who are physically active. At least 25 people with type 1 diabetes will be asked to perform 25 sports activities of at least half an hour, wear an activity tracker (day and night) and chest strap (during sports activities), and log data on food intake, periods and type of physical activity, and feelings (e.g., sick, stress) in a diary app. Diabetes data such as insulin administration and sensor data will be collected through diabetes management platforms. The primary endpoint involves a database containing data on glucose, insulin administration, physical activity, and food intake of people with type 1 diabetes for statistical analyses and visualizations regarding the relationship between physical activity and blood glucose response.
