Fatigability Compared Men and Women Induced According to the Distance Traveled on an Ultra-marathon in the Mountains

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.
