NCT ID NCT07372859
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study will follow 120 female runners during ultra-endurance races (69-80 km) to see how their hearts and inflammation levels change. Researchers will use ultrasound scans before, during, and after the race, and link those changes to hormone levels like estrogen and testosterone. The goal is to better understand women's unique heart responses to extreme exercise.
