Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

It is not fully understood in children how much of hepatic and muscle glycogen is used during a night and how they are replenished after a breakfast. This study aims to analyze the glycogen metabolism before and after an overnight sleep as well as after a breakfast in children between 8 and 12 years old.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
