Glycogen Metabolism in Children
Measurement of Glycogen Replenishment in Children After an Overnight Fast
調査の概要
詳細な説明
The aim of the study is to investigate if liver and muscle glycogen stores are depleted in children after overnight fasting and to what extend the stores are replenished with the intake of small breakfast.
The study is a balanced incomplete crossover design. Participants (children between 8 and 12 years old) have to be two periods of two days in the study. They will be randomized in 6 arms, receiving either water, 1 serving of a small breakfast (Breakfast 1) or 2 servings of the small breakfast (Breakfast 2).
An Interim Analysis after 9 completed subjects will be performed in order to calculate the total number of subjects needed to adequately power the Primary Endpoint.
