Maximal stress tests are currently considered the gold standard. The Institut f\u00fcr Pr\u00e4vention und Nachsorge, Cologne (IPN) test may be an alternative when maximal patient load is not indicated. The universality of the test is well-documented in sport, but the reliability of this test is unknown. The aim of this study was to assess between-trial and between-day reliability for parameters assessed by the IPN stress test in cardiological patients.: In a study of 24 patients aged 39 to 79 years with cardiovascular diseases, the IPN cycle ergometer short test was performed (submaximal performance test). The reliability of heart rate, systolic and diastolic pressure, absolute power at submaximal load, relative performance at submaximal load and target heart rate were assessed. Good (Interclass Correlation Coefficient (ICC) values ranged from 0.832 to 0.894) and excellent (ICC values ranged from 0.904 to 0.969) between-trial reliability was noted. Between-day reliability was good (ICC values from 0.777 to 0.895) and excellent (ICC values from 0.922 to 0.950). The obtained results suggest that the IPN test may be a reliable tool for use in the assessment of cardiological patients, avoiding the implementation of maximal efforts when excessive patient load is not recommended.<\/jats:p>","DOI":"10.3390\/jcm9051552","type":"journal-article","created":{"date-parts":[[2020,5,21]],"date-time":"2020-05-21T11:31:18Z","timestamp":1590060678000},"page":"1552","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Assessment of Measurement Reliability for the IPN Test in Cardiac Patients"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0589-0554","authenticated-orcid":false,"given":"\u0141ukasz","family":"Oleksy","sequence":"first","affiliation":[{"name":"Physiotherapy and Sports Centre, Rzeszow University of Technology, 35-959 Rzeszow, Poland"},{"name":"Oleksy Medical &amp; Sports Sciences, 37-100 \u0141a\u0144cut, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9218-6153","authenticated-orcid":false,"given":"Agnieszka","family":"Skiba","sequence":"additional","affiliation":[{"name":"Institute of Clinical Rehabilitation, University of Physical Education in Krakow, 31-571 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1025-0508","authenticated-orcid":false,"given":"Iwona","family":"Sulowska","sequence":"additional","affiliation":[{"name":"Institute of Clinical Rehabilitation, University of Physical Education in Krakow, 31-571 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcin","family":"Tr\u0119bowicz","sequence":"additional","affiliation":[{"name":"Maria Curie-Sklodowska University Branch in Pu\u0142awy, 24-100 Pu\u0142awy, Poland"},{"name":"\u201cWerandki\u201d Diagnostics &amp; Physiotheraphy Centre, 24-140 Na\u0142\u0119cz\u00f3w, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bartosz","family":"Rukasz","sequence":"additional","affiliation":[{"name":"Military Clinical Hospital with Outpatient Clinic, 20-049 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artur","family":"Stolarczyk","sequence":"additional","affiliation":[{"name":"Orthopaedic and Rehabilitation Department, Medical University of Warsaw, 02-091 Warsaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3044-3422","authenticated-orcid":false,"given":"Joanna","family":"Zyznawska","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Department of Physiotherapy, Jagiellonian University Medical College Krakow, 31-008 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4366-5091","authenticated-orcid":false,"given":"Anna","family":"Mika","sequence":"additional","affiliation":[{"name":"Institute of Clinical Rehabilitation, University of Physical Education in Krakow, 31-571 Krakow, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1016\/S1836-9553(13)70149-8","article-title":"Long-term aerobic exercise maintains peak VO2, improves quality of life, and reduces hospitalisations and mortality in patients with heart failure","volume":"59","author":"Fernhall","year":"2013","journal-title":"J.
