Study Purpose

The STRONG research study aims to understand how girls’ muscles use different fuels in their body (carbs and fat) to provide energy for different levels of activity.

This research is important for understanding how to best refuel the body when it uses up energy.

About the Study

STRONG participants and parents will attend an initial screening visit at Pennington Biomedical to learn about the study, take part in physical tests, and receive a wearable device to track physical activity, which will be used for 7 days at a time and returned at a later visit.

Participants will have two additional study visits to Pennington Biomedical (one at the beginning of the study and one at the end) and stay for 24 hours in the metabolic chamber each time. The metabolic chamber is a special room that measures breathing and energy use. This room is like a bedroom with a window, bed, desk, TV and phone. The study staff will share more about the room should your child qualify for the study.
