Testing how much protein is needed to prevent overnight hypos which can happen after exercise
When people with type 1 diabetes exercise at moderate intensity (e.g. jogging, cycling and swimming) in the late afternoon, this can cause hypos when they are sleeping. We also know protein can raise blood glucose levels for a few hours after a meal.
We are now running a study to see how much protein is necessary to prevent overnight hypos without causing high blood glucose levels.
This is an important study for two reasons: (1) it would be ideal if we can prevent hypos without causing high blood glucose levels, (2) taking protein after exercise is useful for both muscle building and post-exercise muscle repair.
In this study, you will perform 45 minutes of cycling on a stationary bike in the late afternoon at Perth Children's Hospital, and drink a protein drink at home, later in the night. You will do this on three different days. You will also wear a Dexcom G5 sensor for the study days, which we will provide if you are not currently using this system.
You are eligible for this study if you have type 1 diabetes, are aged 12-25 years old, have had diabetes for more than one year, with HbA1c <9%, and are otherwise healthy.
