Hypoglycemia is the main barrier for physical activity practice of patients with type 1 diabetes (T1D). For postprandial exercise, anticipation with meal insulin bolus reduction is the recommended method to reduce exercise-associated hypoglycemic risk. The impact of faster acting Aspart (FiAsp) pharmacokinetic on hypoglycemic risk has not yet been explored. This study will explore two different timings for exercise onset.

Objective: To compare the impact of rapid-acting insulin Aspart and faster acting Aspart (FiAsp) on glucose reduction during exercise.

Design: This study is a randomized, four-way, crossover study to compare the efficacy of 1) rapid-acting insulin Aspart, and 2) FiAsp on glucose reduction during an exercise performed 60 minutes or 120 minutes after breakfast. The insulin used and the timing of the exercise will be randomized. This project will be conducted at Institut de recherches cliniques de Montral (IRCM, Montreal, Canada).

Hypothesis: Faster acting Aspart (FiAsp) will be non-inferior to insulin Aspart for hypoglycemic risk.
