During each testing session, athletes first completed a ramped arm-ergometer exercise test to<br>\nexhaustion for the determination of peak work rate and peak oxygen uptake. Following a 30 minute break,<br>\nathletes completed a sub-maximal arm-ergometer test at 20, 40, 60, and 80% of peak work rate. Inspiratory<br>\ncapacity maneuvers were performed in the final minute of each stage to determine end-expiratory lung<br>\nvolume (EELV) and calculate end-inspiratory lung volume (EILV). Breath-by-breath cardiopulmonary<br>\nindices were recorded throughout both exercise tests. On a separate day, athletes were assessed for time<br>\nto complete a field-based 20x20 metre repeated sprint test.<br>\n<strong>RESULTS</strong>: Following RMT, there were increases in peak work rate (69±22 post vs. 60±20 W pre, p=0.03),<br>\noxygen uptake (20.3±5.9 vs. 17.6±5.0 mL/kg/min, p=0.04), and minute ventilation (54±18 vs. 46±12 L/min,<br>\np=0.03). Dynamic hyperinflation was present during all tests as evidenced by an increase in EELV with<br>\nincreasing exercise intensity; however, during post-RMT testing both EELV and EILV were significantly<br>\nlower than pre-RMT throughout exercise (p<0.05). At follow-up, no indices were different from post-RMT.<br>\nField-based repeat sprint performance was unchanged by RMT.<br>\n<strong>DISCUSSION</strong>: RMT enhances exercise capacity in athletes with tetraplegia. Whether this is due to an<br>\nincreased peak ventilation or the circulatory benefits of an enhanced respiratory muscle pump, lower<br>\noperating lung volumes, and/or an attenuation of the respiratory muscle metaboreflex remains to be<br>\ndetermined.</p>", "license": "https://creativecommons.org/licenses/by/4.0/legalcode", "creator": [ { "affiliation": "ICORD/University of British Columbia, VANCOUVER, Canada", "@type": "Person", "name": "West, C.R." }, { "affiliation": "ICORD/University of British Columbia, VANCOUVER, Canada", "@type": "Person", "name": "Gee, C.M." }, { "affiliation": "ICORD/University of British Columbia, VANCOUVER, Canada", "@type": "Person", "name": "Williams, A.M." }, { "affiliation": "University of British Columbia, VANCOUVER, Canada", "@type": "Person", "name": "Sheel, A.W." }, { "affiliation": "University of British Columbia, VANCOUVER, Canada", "@type": "Person", "name": "Eves, N.D." } ], "headline": "RehabMove 2018: EFFECT OF RESPIRATORY MUSCLE TRAINING ON EXERCISE CAPACITY AND RESPIRATORY MECHANICS IN ATHLETES WITH TETRAPLEGIA", "image": "https://zenodo.org/static/img/logos/zenodo-gradient-round.svg", "datePublished": "2018-11-16", "url": "https://zenodo.org/record/1490143", "@type": "ScholarlyArticle", "@context": "https://schema.org/", "identifier": "https://doi.org/10.5281/zenodo.1490143", "@id": "https://doi.org/10.5281/zenodo.1490143", "workFeatured": { "url": "http://rehabmove2018.com/", "location": "Groningen, The Netherlands", "@type": "Event", "name": "6th International RehabMove State-Of-The-Art Congress 2018" }, "name": "RehabMove 2018: EFFECT OF RESPIRATORY MUSCLE TRAINING ON EXERCISE CAPACITY AND RESPIRATORY MECHANICS IN ATHLETES WITH TETRAPLEGIA" }
