There were no differences in EMG responses between older and younger men. Younger men were more likely to report shallow breathing (<jats:italic>p<\/jats:italic>\u2009=\u20090.005) than older men. Our findings showed younger and older men had similar respiratory neuromuscular activation patterns and reported different dyspnea descriptors, and that older men had greater expiratory muscle pressure generation during exercise. Greater expiratory muscle pressures in older men may be due to compensatory mechanisms designed to offset increasing airway resistance due to aging. These results may have implications for exercise\u2010induced expiratory muscle fatigue in older men.<\/jats:p>","DOI":"10.14814\/phy2.15794","type":"journal-article","created":{"date-parts":[[2023,8,22]],"date-time":"2023-08-22T10:01:12Z","timestamp":1692698472000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The
