Opis
Inclusion Criteria:
- Males and females ≥ 14 years of old.
- Clinical diagnosis of type 1 diabetes for at least one year.
- Last (less than 3 months) HbA1c ≤ 10%.
- Patients using multiple daily injections with basal-bolus insulin regimen.
Exclusion Criteria:
- Clinically significant microvascular complications: nephropathy (estimated glomerular filtration rate below 40 ml/min), neuropathy (especially diagnosed gastroparesis) or severe proliferative retinopathy as judged by the investigator.
- Recent (< 3 months) acute macrovascular event e.g. acute coronary syndrome or cardiac surgery.
- Abnormal blood panel and/or anemia.
- Ongoing pregnancy.
- Severe hypoglycemic episode within two weeks of screening.
- Other serious medical illness likely to interfere with study participation or with the ability to complete the exercise periods by the judgment of the investigator (e.g. orthopedic limitation).
- Treatment with CSII (Continuous Subcutaneous Insulin Infusion) "insulin pump therapy".

Aktywny komparator: Full snack given before exercise
A snack containing ~0.5g of carbohydrates per kilogram of body weight will be given 5 minutes before exercise
|
Participants will be admitted at IRCM at 14:00.
At 15:30, participants will performed a 60-minute exercise on the ergocycle at 60% of VO2 peak (moderate intensity).
During exercise, capillary glucose levels will be measured every 10 minutes.
At 16:30, the exercise will be completed and capillary glucose levels will be monitored every 20 minutes for 1 hour.
At 17:30, the participant will be discharged.

Aktywny komparator: Distributed snack over exercise period
A snack containing ~0.5g of carbohydrates per kilogram of body weight distributed this way will be given: ~40% given 5 minutes before exercise, ~30% after 20 minutes of exercise and the last ~30% after 40 minutes of exercise.
