Summary

This study is working to create better exercise tests for children with cystic fibrosis, sickle cell disease, or long COVID. Current tests are designed for healthy athletes and may not be safe or useful for these kids. Researchers will track 240 children over 3-4 years, measuring their breathing, heart rate, body composition, and activity levels to develop new testing guidelines.
