However, maximal VO<jats:sub>2<\/jats:sub> is not achievable in the supine position and standardizing submaximal exercise intensities remains challenging. Using heart rate or workload could be a viable option to translate VO<jats:sub>2<\/jats:sub>\u2010based submaximal exercise intensities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aim<\/jats:title><jats:p>To translate submaximal exercise intensities upright cycling exercise (UCE) to supine push\u2013pull exercise (SPPE), by comparing heart rate or workload determined during UCE, with heart rate and workload during SPPE at similar exercise intensities.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>Sixteen healthy young adults (20.4\u2009\u00b1\u20092.2 years; 8 female) underwent cardiopulmonary UCE and SPPE testing [mean\u2009\u00b1\u2009standard deviation maximal VO<jats:sub>2<\/jats:sub>: 3.2\u2009\u00b1\u20090.6 vs. 5\u2009\u00b1\u20090.3\u2009L\u2009min<jats:sup>\u22121<\/jats:sup>, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001 and median (interquartile range) of the maximum workload: 310 (244, 361) vs. 98 (98,\u00a0100), <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, respectively]. Heart rate at 40% and 60% of maximal VO<jats:sub>2<\/jats:sub>, as determined by UCE, showed low bias (\u22123 and 0\u2009bpm, respectively) and wide limits of agreement (\u00b126 and \u00b128\u2009bpm, respectively), in Bland\u2013Altman analysis. VO<jats:sub>2<\/jats:sub>\/Workload relation was exponential and less efficient during SPPE compared to UCE.

Using workload, an ergometer specific, model\u2010based mean can be used to determine exercise intensities during SPPE. Individual variations in response to posture and movement change are high. During clinical interpretation of exercise CMR, individual exercise intensity has to be considered.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cpf.12784","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T08:53:36Z","timestamp":1661763216000},"page":"10-19","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Standardizing submaximal exercise intensities for use of supine push\u2013pull exercise during cardiovascular magnetic resonance"],"prefix":"10.1111","volume":"43","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1998-181X","authenticated-orcid":false,"given":"Jarno J.","family":"Steenhorst","sequence":"first","affiliation":[{"name":"Department of Cardiology Erasmus MC, University Medical Center Rotterdam  Rotterdam The Netherlands"},{"name":"Department of Pediatrics, Division of Pediatric Cardiology Erasmus MC, University Medical Center Rotterdam  Rotterdam The Netherlands"},{"name":"Department of Radiology and Nuclear Medicine Erasmus MC, University Medical Center Rotterdam  Rotterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alexander","family":"Hirsch","sequence":"additional","affiliation":[{"name":"Department of Cardiology Erasmus MC, University Medical Center Rotterdam  Rotterdam The Netherlands"},{"name":"Department of Radiology and Nuclear Medicine Erasmus MC, University Medical Center Rotterdam  Rotterdam The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linda E.
