Abstract Body

Regular exercise has numerous health and fitness benefits for people living with type 1 diabetes, however the acute management of glycemia during and after a bout of exercise remains a major clinical challenge. The Type 1 Diabetes Exercise Initiative (T1Dexi) is a real-world study designed to create a shareable dataset that will help researchers better understand modifiable and non-modifiable factors that may influence the glycemic responses to different types of exercise in those living with type 1 diabetes. This session will highlight results of a one-month observational study of exercise-related glycemia from 497 adults in the US living with type 1 diabetes (n= 183 on standard pump therapy; n=226 on hybrid closed loop; n= 88 on multiple daily injections). Participants self-reported physical activity events, including randomized assignment to study-designed aerobic, resistance or interval type exercise, and food intake using a custom smart phone application. Data collection also included insulin delivery and activity monitors (Polar heart rate chest strap, Verily Health Watch) to contextualize each activity event and relate to exercise-associated changes in glycemia as assessed by continuous glucose monitoring (Dexcom G6).
