How Ultra-Running Affects Your Kidneys
Treatments studied
Part of Kidney & urinary, Women’s health & pregnancy clinical trials.
This study follows runners in the Western States 100-mile endurance race to understand how extreme endurance running affects kidney function. Researchers will collect data before, during, and after the race to see if kidneys are temporarily stressed and how they recover.
