The physiological demands of marathon and ultra-marathon running are substantial,
affecting multiple body systems. There have been several reviews on the physiological …

Purpose: Ultra-marathon running offers the unique possibility to investigate the mechanisms
contributing to the limitation of endurance performance. Investigations of locomotor muscle …

Respiratory muscle fatigue has been reported following short bouts of high-intensity
exercise, and prolonged, moderate-intensity exercise, as evidenced by decrements in …

This study aimed to assess the effects of an extreme mountain ultramarathon (MUM, 330 km,
24 000 D+) on lung function. Twenty‐nine experienced male ultramarathon runners …

We measured lung mechanics and metabolic parameters, first in a series of 15 marathon (M)
and 12 half-marathon (H) runners, before and 2.5 h after the race, in order to assess the …

Based on observations of impaired lung function after marathon and ultramarathon running,
it was hypothesized that the decline in running speed during a 24-h ultramarathon may be …

Respiratory muscle fatigue has been demonstrated in the laboratory as well as in
pathological states, but whether it occurs in healthy individuals under physiological …

This study was designed to investigate the mechanisms underlying the significant reductions
in vital capacity after marathon racing originally reported over 50 years ago. Spirometric …

Regular physical activity decreases the risk of cardiovascular disease, type II diabetes,
obesity, certain cancers, and all-cause mortality. Nevertheless, there is mounting evidence …

ABSTRACT 1 Purpose. Despite a growing body of literature on the physiological responses
to ultramarathon, there is a 2 paucity of data in females. This study assessed the female …
