The diaphragm and chest wall muscles act together like a bellows to pump air in and out of the chest. To breathe in these muscles contract to expand the chest cavity, causing a pressure drop into which the air flows. To breathe out, you simply relax these ‘inspiratory’ muscles and the chest springs back forcing

A study published in The Journal of Strength and Conditioning Research (September 26th 2015) tested the hypothesis that short-duration running exercise would induce Inspiratory Muscle Fatigue (IMF) which may limit performance. This follows studies that found IMF occurs after short-duration swimming exercise. Eight female middle-distance runners were the subjects of this study which found that
Published in the European Journal of Applied Physiology (August 2014, Volume 114, Issue 8, pp 1619-1633). STUDY Locomotor and diaphragm muscle fatigue in endurance athletes performing time-trials of different durations Thomas U. Wüthrich, Elisabeth C. Eberle, Christina M. Spengler Purpose: “Fatigue in leg muscles might differ between running and cycling due to inherent differences in
Dr Mitch Lomax, Sport and Exercise Scientist and Senior Lecturer in Sport and Exercise Physiology at the University of Portsmouth, gave an interview to Swimming Science in which she discussed her investigation into the breathing demands of swimming and the discovery that the occurrence and consequences of breathing muscle fatigue in swimming had been overlooked.
A paper was published online in the Journal of Strength and Conditioning Research that revealed how “the presence of inspiratory muscle fatigue affects the activity of the latissimus dorsi during front crawl sprinting.” Research: Inspiratory muscle fatigue affects latissimus dorsi but not pectoralis major activity during arms only front crawl sprinting Lomax M, Tasker L,
