Why do marathon runners have low muscle mass?

Cardio Burns Muscle Olympic distance runners, for example, have very little muscle and fat. That’s because long-distance running breaks down muscle instead of building it. A 2017 report in Medicine and Science in Sports and Exercise showed this robust effect in ultra-marathoner runners.

Why do marathon runners look so unhealthy?

Do marathon runners have low body fat?

This study, however, aimed to explore the factors contributing to fast or personal best marathon race times in recreational male marathoners. The study showed that a low body fat percentage and high-intensity speed training are the two most prevalent factors in predicting race completion times.
