Patients with COPD (Medical Research Council dyspnoea grade 2\u20135) and patients with CHF (New York Heart Association class II\u2013IV) performed two incremental shuttle walk tests (ISWT) following familiarisation and two incremental cycle ergometer tests (ICE) within 2 weeks. Both tests were repeated on completion of a pulmonary rehabilitation (PR) programme. One hundred and twelve patients were recruited. In response to exercise, patients with COPD were more likely than patients with CHF to have a ventilatory limitation ( p &lt; 0.001) and less likely to have a cardiovascular limitation ( p &lt; 0.001). The ISWT distance and ICE peak volume of oxygen uptake (VO\n                    <jats:sub>2<\/jats:sub>\n                    Peak) were similarly repeatable ( p = 0.11 and p = 0.47 for time and disease effect) and responsive to PR ( p = 0.44 and p = 0.67) between diseases. There was no difference in repeatability or responsiveness with either a ventilatory or cardiovascular limitation to exercise ( p &gt; 0.20 for all comparisons). The coefficient of repeatability across the cohort was 60 m for the ISWT and 0.270 L\/minute for ICE VO\n                    <jats:sub>2<\/jats:sub>\n                    Peak. The minimum important difference (MID) for the ISWT in both diseases for PR was 30 m. The repeatability and responsiveness of the ISWT distance and ICE VO\n                    <jats:sub>2<\/jats:sub>\n                    Peak are similar between patients with COPD and CHF and are unaffected by differences in exercise limitation. A change of 60 m in the ISWT or 0.270 L\/minute in ICE VO\n                    <jats:sub>2<\/jats:sub>\n                    Peak is required to be 95% certain that a true change has occurred within an individual patient. For a group of patients with either COPD or CHF, the MID for the ISWT distance is estimated to be 30 m.\n                  <\/jats:p>","DOI":"10.1177\/1479973119887965","type":"journal-article","created":{"date-parts":[[2019,11,11]],"date-time":"2019-11-11T22:06:43Z","timestamp":1573510003000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Are the measurement properties of incremental exercise tests similar between patients with COPD and CHF?"],"prefix":"10.1177","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9654-7075","authenticated-orcid":false,"given":"Theresa C","family":"Harvey-Dunstan","sequence":"first","affiliation":[{"name":"Division of Physiotherapy and Rehabilitation Sciences, School of Health Sciences, University of Nottingham, Nottingham, UK"},{"name":"Centre for Exercise and Rehabilitation Science, NIHR Leicester Respiratory Biomedical Research Centre (Respiratory), Leicester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sally J","family":"Singh","sequence":"additional","affiliation":[{"name":"Centre for Exercise and Rehabilitation Science, NIHR Leicester Respiratory Biomedical Research Centre (Respiratory), Leicester, UK"},{"name":"Department of Respiratory Medicine, University Hospitals of Leicester NHS Trust, Leicester, UK"},{"name":"Department of Respiratory Sciences, University of Leicester, Leicester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael C","family":"Steiner","sequence":"additional","affiliation":[{"name":"Centre for Exercise and Rehabilitation Science, NIHR Leicester Respiratory Biomedical Research Centre (Respiratory), Leicester, UK"},{"name":"Department of Respiratory Medicine, University Hospitals of Leicester NHS Trust, Leicester, UK"},{"name":"Department of Respiratory Sciences, University of Leicester, Leicester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael D","family":"Morgan","sequence":"additional","affiliation":[{"name":"Centre for Exercise and Rehabilitation Science, NIHR Leicester Respiratory Biomedical Research Centre (Respiratory), Leicester, UK"},{"name":"Department of Respiratory Medicine, University Hospitals of Leicester NHS Trust, Leicester, UK"},{"name":"Department of Respiratory Sciences, University of Leicester, Leicester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachael A","family":"Evans","sequence":"additional","affiliation":[{"name":"Centre for Exercise and Rehabilitation Science, NIHR Leicester Respiratory Biomedical Research Centre (Respiratory), Leicester, UK"},{"name":"Department of Respiratory Medicine, University Hospitals of Leicester NHS Trust, Leicester, UK"},{"name":"Department of Respiratory Sciences, University of Leicester, Leicester, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2019,11,11]]},"reference":[{"key":"bibr1-1479973119887965","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(15)60692-4"},{"key":"bibr2-1479973119887965","doi-asserted-by":"publisher","DOI":"10.1378\/chest.123.5.1416"},{"key":"bibr3-1479973119887965","doi-asserted-by":"publisher","DOI":"10.1093\/ajcn\/71.5.1033"},{"key":"bibr4-1479973119887965","doi-asserted-by":"publisher","DOI":"10.1136\/openhrt-2014-000163"},{"key":"bibr5-1479973119887965","first-page":"CD003793","volume":"2","author":"McCarthy B","year":"2015","journal-title":"Cochrane Database Syst Rev"},{"key":"bibr6-1479973119887965","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(97)00015-6"},{"key":"bibr7-1479973119887965","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.154.2.8756820"},{"issue":"16","key":"bibr8-1479973119887965","first-page":"e240","volume":"128","author":"Writing Committee Members","year":"2013","journal-title":"Circulation"},{"key":"bibr9-1479973119887965","unstructured":"Global Initiative for Chronic Obstructive Lung Disease (GOLD).
