Carbohydrate-based Strategies to Prevent Exercise-induced Hypoglycemia
2020年6月8日 更新者：Rémi Rabasa-Lhoret、Institut de Recherches Cliniques de Montreal
Comparison of Two Carbohydrate Intake Strategies to Improve Glucose Control During Exercise in Adolescents and Adults With Type 1 Diabetes
To prevent hypoglycemia during prolonged exercise (>30 minutes), additional carbohydrate intake is frequently required.
Carbohydrate intake required will vary with insulin regimens, timing and type of exercise as well as starting blood glucose level.
In addition to the amount of carbohydrate ingested, the timing of carbohydrate intake could also have an impact on glucose control during exercise.
Therefore, the objective of this study will be to compare the efficacy of two snacking strategies to maintain glucose levels in the target range during an exercise period in adolescents and adults with type 1 diabetes: 1) a snack containing ~0.5g of carbohydrates per kilogram of body weight - rounded to the nearest 5g - given 5 minutes before exercise; 2) a snack containing ~0.5g of carbohydrates per kilogram of body weight - rounded to the nearest 5g - distributed this way: ~40% given 5 minutes before exercise, ~30% after 20 minutes of exercise and the last ~30% after 40 minutes of exercise.

有源比较器：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.

有源比较器：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.
