ClinConnect Summary

This clinical trial, titled "Protein Requirements for Active Children," is exploring how much protein healthy children aged 8 to 10 years need, especially those who are very active. Researchers believe that current guidelines for protein intake might be too low, particularly for kids who exercise a lot. To find out more, they will use a special method to measure how the body uses protein in children with different activity levels.

To be part of this study, children must be between 8 and 10 years old, healthy, and of normal weight. They should either be classified as active, getting more than an hour of exercise each day, or sedentary, getting less than that. Participants will need to stop taking certain nutritional supplements for two weeks before each testing visit. The trial is currently looking for participants, and children of all races and backgrounds are encouraged to join. Families can expect their children to undergo fitness tests and assessments related to their activity levels, helping researchers better understand the protein needs of active kids.
