However, exercise intolerance may be caused by excessive ventilatory. Exposure to oxygen-replete air reduces this ventilatory overload, improves sleep and enhances responses to exercise. This study examine the impact of the acute manipulation of oxygen availability during inter-exercise recovery period of an intermittent cycling exercise on perceptual responses.\n\nthis randomized, controlled, study include adult patient with COPD. On separate days, 50 patients with COPD completed four sets of 4-min at 85% of VO2peak intercept by 3-min of passive recovery in two randomized between-sets recovery conditions. Rating exertion perception, gaz exchanges, heart rate, sleep quality and nocturnal heart rate variability were assessed.\n\nHypoxic exposure during inter-repetition recovery phases would reduce the ventilatory load during exercise. What's more, patients would not be forced to perform the sporting gesture in a restricted space or wearing a mask, limiting dyspnea and the perceived difficulty of the effort. Lastly, the induction of hypoxic stress during the re-training session helped to improve patients' sleep.",[26,27,28,29,30],"Intermittent Hypoxia","Exercise Recovery","Intermittent Exercise","Rating Exertion Perception","Sleep",[32,33,34,35,36],"intermittent hypoxia","exercise recovery","intermittent exercise","rating exertion perception","sleep","NOT_YET_RECRUITING","2025-09-30",{"date":40,"type":41},"2025-10-01","ACTUAL",{"date":43,"type":20},"2025-10",{"date":45,"type":20},"2027-08",{"name":47,"class":48},"Centre Hospitalier Universitaire, Amiens","OTHER",""]
