After each session, an \u223c10-minute structured interview was conducted to gather insights into participants\u2019 perceptions of the exercise under each condition. Interview transcripts were analyzed for key themes, which were presented in a pen profile. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> At 4000\u00a0m, 5 participants perceived light-headedness and 2 had difficulty focusing, which were not experienced at lower altitudes. Difficulty breathing increased progressively with hypoxic severity, from 1 report in normoxia to 9 at 4000\u00a0m. Limb discomfort was consistently reported across all conditions. <jats:italic><jats:bold>Conclusion<\/jats:bold>:<\/jats:italic> Despite comparable physiological responses during HR-clamped cycling, hypoxia severity influenced selected perceived sensations (ie,\u00a0difficulty focusing, difficulty breathing, and light-headedness). These effects should be considered when selecting the desired hypoxic severity for HR-clamped cycling.<\/jats:p>","DOI":"10.1123\/ijspp.2024-0519","type":"journal-article","created":{"date-parts":[[2025,5,13]],"date-time":"2025-05-13T18:46:32Z","timestamp":1747161992000},"page":"1009-1012","source":"Crossref","is-referenced-by-count":0,"title":["Exercise Sensations During Moderate-Intensity Heart-Rate-Clamped Cycling in Graded Hypoxia: A Qualitative Approach"],"prefix":"10.1123","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0227-4980","authenticated-orcid":true,"given":"Siu Nam","family":"Li","sequence":"first","affiliation":[{"name":"School of Human Sciences, Exercise and Sports Science, University of Western Australia, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3895-0015","authenticated-orcid":true,"given":"Peter","family":"Peeling","sequence":"additional","affiliation":[{"name":"School of Human Sciences, Exercise and Sports Science, University of Western Australia, Perth, WA, Australia"},{"name":"Department of Sport Science, Western Australian Institute of Sport, Mt Claremont, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5653-6651","authenticated-orcid":true,"given":"Timothy","family":"Budden","sequence":"additional","affiliation":[{"name":"School of Human Sciences, Exercise and Sports Science, University of Western Australia, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0660-488X","authenticated-orcid":true,"given":"Aaron","family":"Simpson","sequence":"additional","affiliation":[{"name":"School of Human Sciences, Exercise and Sports Science, University of Western Australia, Perth, WA, Australia"},{"name":"The Kids Research Institute Australia, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2484-4019","authenticated-orcid":true,"given":"Brendan R.","family":"Scott","sequence":"additional","affiliation":[{"name":"PHysical Activity, Sport and Exercise (PHASE) Research Group, School of Allied Health (Exercise Science), Murdoch University, Perth, WA, Australia"},{"name":"Centre for Healthy Ageing, Murdoch University, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3331-1177","authenticated-orcid":true,"given":"Jeremiah J.","family":"Peiffer","sequence":"additional","affiliation":[{"name":"PHysical Activity, Sport and Exercise (PHASE) Research Group, School of Allied Health (Exercise Science), Murdoch University, Perth, WA, Australia"},{"name":"Centre for Healthy Ageing, Murdoch University, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alex","family":"Shaykevich","sequence":"additional","affiliation":[{"name":"School of Human Sciences, Exercise and Sports Science, University of Western Australia, Perth, WA, Australia"},{"name":"Perron Institute for Neurological and Translational Science, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4797-182X","authenticated-orcid":true,"given":"Olivier","family":"Girard","sequence":"additional","affiliation":[{"name":"School of Human Sciences, Exercise and Sports Science, University of Western Australia, Perth, WA, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"1","key":"r1","series-title":"Front Pediatr","doi-asserted-by":"publisher","DOI":"10.3389\/fped.2015.00058","article-title":"Hypoxic conditioning as a new therapeutic modality","volume":"3","author":"Verges S","year":"2015","unstructured":"Verges S, Chacaroun S, Godin-Ribuot D, Baillieul S.
