There is no studies that compared potential of two types of HRV parameters (time-domain and frequency-domain) in predicting exercise exertion level using discriminant analysis. The main goal of this study was to compare potential of HRV time-domain parameters versus HRV frequency-domain parameters in classifying exercise exertion level. Rest, exercise, and recovery categories were used in classification models. Overall 79.5% classification agreement by the time-domain parameters as compared to overall 52.8% classification agreement by frequency-domain parameters demonstrated that the time-domain parameters had higher potential in classifying exercise exertion levels.<\/jats:p>","DOI":"10.3233\/978-1-61499-538-8-171","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:10:01Z","timestamp":1740132601000},"source":"Crossref","is-referenced-by-count":0,"title":["Real-Time Classification of Exercise Exertion Levels Using Discriminant Analysis of HRV Data"],"prefix":"10.3233","author":[{"family":"Jeong In cheol","sequence":"additional","affiliation":[]},{"family":"Finkelstein Joseph","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","Enabling Health Informatics Applications"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T10:29:31Z","timestamp":1740133771000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISBN&isbn=978-1-61499-537-1&spage=171&doi=10.3233\/978-1-61499-538-8-171"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-538-8-171","relation":{"is-cited-by":[{"id-type":"doi","id":"10.3389\/fphys.2018.00401","asserted-by":"object"}]},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2015]]}}}
