Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Acute physiological consequences of ultra-marathon running are still unknown, particularly in women. Some studies have suggested that the proportion of fatigue attributable to peripheral and central mechanisms varies between males and females; however, results are contradictory.

The results from the investigators of the present experiment in two studies conducted in 2009 and 2012 showed that:

* A large part of fatigue induced by a mountain ultra-marathon could be attributed to central fatigue in males and that,
* Females exhibited less peripheral fatigue in the plantar flexors than males did after a 110-km ultra-trail-running race.

According to the literature, there seems to be a plateau in fatigue after 12-15 hours of running.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Thus, the main purpose of the present project is to investigate whether sex differences in neuromuscular fatigue in plantar flexors depend on the distance (\> 100 km vs \< 60 km).
