Abstract
In this randomized, three-armed crossover study, we will look at the relationship between carbohydrate and energy intake, and glycemic control, with differing types of exercise in subjects with T1D. Participants will be observed for three weeks, with each week focusing on a different exercise intervention: 1) aerobic exercise, 2) resistance training, and 3) no explicit exercise. During the aerobic exercise and resistance training weeks, the actual exercise intervention will occur on two nonconsecutive days. Participants will photograph each of their meals on a smartphone, which will be analyzed to quantify energy and macronutrient intake on the day of and the day after exercise. Glycemic control will be collected via a continuous glucose monitoring system.
