Two identical devices from each system were independently connected to a metabolic simulator (VacuMed), and 2\u2009min\u00a0of steady\u2010state data was recorded at simulated oxygen uptake (V\u0307O<jats:sub>2<\/jats:sub>) of 1, 2, 3, and 4\u2009L\u2219min<jats:sup>\u22121<\/jats:sup> achieved through minute ventilation (<jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub>) of 30, 60, 105, and 150\u2009L\u2219min<jats:sup>\u22121<\/jats:sup>. Each metabolic analyzer recorded data three times for each \u201cintensity\u201d in a randomized order, and assessments were completed on two separate days. Douglas bag\u2010based measurements were also made once at each simulated \u201cintensity\u201d. Measured steady\u2010state data (average of final 1.5\u2009min) for both V\u0307O<jats:sub>2<\/jats:sub> (STPD) and <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub> (ATPS) were compared with simulated values to assess validity, repeated values between and within days assessed reliability, and between\u2010device comparisons provided transferability. Including both COSMED devices at all intensities, the mean percent error for V\u0307O<jats:sub>2<\/jats:sub> was 3.5% (range: \u22122.5%\u20138.1%) and, for <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub>, was 2.0% (\u22120.5%\u20137.6%). For the VO2Master, these values averaged 0.6% (\u22129.3%\u20134.8%) and 1.1% (\u22126.3%\u20134.0%) for V\u0307O<jats:sub>2<\/jats:sub> and <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub>, respectively. Mean percent error for Douglas Bag was 1.5%, \u22123.7%, \u22123.1%, and \u22122.0% for 1, 2, 3, and 4\u2009L\u2219min<jats:sup>\u22121<\/jats:sup>, respectively. Between\u2010day differences (reliability) for V\u0307O<jats:sub>2<\/jats:sub> of both COSMED devices ranged from \u22124.1% to 2.2% (mean 0.1%) and, for both VO2Masters, between \u22121.6% and 11.1% (mean 1.2%). Between\u2010device differences (transferability) ranged from \u22123.5% to 0.5% (mean 1.3%) for COSMED and from \u221211.0% to 3.6% (mean 0.0%) for VO2Master. Mean values and ranges for <jats:italic>V\u0307<\/jats:italic><jats:sub>E<\/jats:sub> were similar. When used appropriately in laboratory settings, the COSMED Quark and VO2Master Pro systems provide gas exchange and ventilatory data within an acceptable range for metabolic testing equipment that are both reliable and transferable between optimally performing devices.<\/jats:p>","DOI":"10.1111\/sms.70019","type":"journal-article","created":{"date-parts":[[2025,1,30]],"date-time":"2025-01-30T07:52:31Z","timestamp":1738223551000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["(Re)assessment of the <scp>COSMED<\/scp> Quark <scp>CPET<\/scp> and <scp>VO2Master<\/scp> Pro Systems for Measuring Pulmonary Gas\u00a0Exchange and Ventilation"],"prefix":"10.1111","volume":"35","author":[{"given":"Johan S.","family":"Thiessen","sequence":"first","affiliation":[{"name":"School of Kinesiology The University of Western Ontario  London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nasimi A.","family":"Guluzade","sequence":"additional","affiliation":[{"name":"School of Kinesiology The University of Western Ontario  London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robin","family":"Faricier","sequence":"additional","affiliation":[{"name":"School of Kinesiology The University of Western Ontario  London Ontario Canada"},{"name":"Lawson Health Research Institute  London Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5656-373X","authenticated-orcid":false,"given":"Daniel A.","family":"Keir","sequence":"additional","affiliation":[{"name":"School of Kinesiology The University of Western Ontario  London Ontario Canada"},{"name":"Lawson Health Research Institute  London Ontario Canada"},{"name":"Toronto General Research Institute Toronto General Hospital  Toronto Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,1,29]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/sms.14599"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2020.01070"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/sms.14490"},{"issue":"4","key":"e_1_2_11_5_1","first-page":"1382","article-title":"Validity and Reliability of the VO2 Master Pro for Oxygen Consumption and Ventilation Assessment","volume":"13","author":"Montoye A.
