For people with type 1 diabetes (T1D), the risk of experiencing hypoglycemia is elevated during and up to 24 hours following physical activity, the fear of which is a leading barrier to physical activity among this population. Increasing dietary protein intake, as recommended by sports nutrition guidelines, may promote a mild, prolonged hyperglycemic effect which may mitigate the risk of exercise-related hypoglycemia. Therefore, the goal of this dissertation was to evaluate the role of protein intake and timing on exercise-related glycemia among adolescents and adults with T1D.Data from the Flexible Lifestyles Empowering Change (FLEX) study were used to evaluate the role of pre-exercise, post-exercise, and daily protein intake on glycemia during and following bouts of moderate-to-vigorous physical activity (MVPA) among adolescents with T1D (n=112) utilizing mixed effects regression modeling. Dietary intake and MVPA were quantified using 24-hour dietary recalls and previous day physical activity records, respectively. Percent time in recommended glucose range (TIR, 70-180mg/dL), percent time below range (TBR, 180mg/dL) during MVPA bouts as well as from bout cessation until the following morning were calculated from continuous glucose monitoring (CGM) data. Additional secondary analyses were conducted using data from an exercise pilot study to evaluate the role of post-exercise protein intake on post-exercise glycemia among adults with T1D following supervised bouts of moderate-intensity continuous training (MICT) or high-intensity interval training (HIIT) performed following an overnight fast. Dietary intake was quantified using 3-day food records and TIR, TBR and TAR were calculated using CGM data.  Protein intakes of at least 10g or 0.125g/kg consumed within 4 hours prior to MVPA were associated with reduced TBR among adolescents with T1D. Additionally, daily protein intakes within sports nutrition guidelines (1.2-2.0g/kg/day) were associated with reduced TAR and increased TIR following MVPA, with stronger associations identified for adolescents with overweight or obesity, those using multiple daily insulin injections, and females. Furthermore, there was a trend (p=0.05) towards reduced TBR following MICT, but not HIIT among adults with T1D. Following sports nutrition guidelines for protein intake may improve the glycemic response to exercise for people living with T1D.
