Understanding glucodynamics in youth with T1D during a variety of physical activities (PA) may help guide management customized to type of activity. The present study profiled PA, heart rate (HR) and glycemia in youth participating in 5-day hockey camp. Youth attending the Dskate hockey camp, which includes daily hockey drills (D), a tournament (T), mixed martial arts (MMA) and off-ice activities (O), were invited to participate. Data were collected from wrist-based HR (Garmin vívosmart® 3) and Dexcom G5. Thirty-one youth (age 13±2 yrs; 94% on CSII and all using CGM; BMI percentile 69±21%; insulin dose 42±18U/d; HbA1c 7.7±0.8%; duration of T1D 6±3yrs) participated in this observational study. During the day camp, time in range (70-180mg/dL) was 57±15% (mean±SD), time >180mg/dL was 41±16%, and the median time <70mg/dL was 1.7% (IQR: 1.0-3.6%). Mean glucose levels during the activity fell from onset in D (from 183±79 to 170±74 mg/dL) and MMA (201±77 to 194±67 mg/dL), but rose in T (174±53 to 188±50 mg/dL) and O (172±63 to 178±60 mg/dL). HR was similar across activities (110±12 bpm). In a cohort of motivated youth attending a hockey camp, glucose levels tend to drop during practice and MMA but tend to rise in tournaments and in off-ice activities. Future studies will use similar wearable technologies to examine glucodynamics in a larger observational study of a more diverse sample of youth living with T1D.
