A total of 24 recreational runners performed a 3\u2010week baseline period, a 2\u2010week overload period, and a 1\u2010week recovery period. Performance was assessed before and after each period with a 3000m running test. Recovery was monitored with daily orthostatic tests, nocturnal HR recordings, questionnaires, and exercise data. The participants were divided into subgroups (overreached\/OR, <jats:italic>n<\/jats:italic>\u00a0=\u00a08; responders\/RESP, <jats:italic>n<\/jats:italic>\u00a0=\u00a012) based on the changes in performance and subjective recovery. The responses to the second week of the overload period were compared between the subgroups. RESP improved their baseline 3000\u00a0m time (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) after the overload period (\u22122.5\u00a0\u00b1\u00a01.0%), and the change differed (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001) from OR (0.6\u00a0\u00b1\u00a01.2%). The changes in nocturnal HR (OR 3.2\u00a0\u00b1\u00a03.1%; RESP \u22122.8\u00a0\u00b1\u00a03.7%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.002) and HR variability (OR \u22120.7\u00a0\u00b1\u00a01.8%; RESP 2.1\u00a0\u00b1\u00a01.6%, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.011) differed between the subgroups. In addition, the decrease in subjective readiness to train (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.009) and increase in soreness of the legs (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.04) were greater in OR compared to RESP. Nocturnal HR, readiness to train, and exercise\u2010derived HR\u2010running power index had \u226585% positive and negative predictive values in the discrimination between OR and RESP individuals. In conclusion, exercise tolerance can vary substantially in recreational runners. The results supported the usefulness of nocturnal HR and subjective recovery assessments in recognizing fatigue states.<\/jats:p>","DOI":"10.1002\/ejsc.12115","type":"journal-article","created":{"date-parts":[[2024,4,27]],"date-time":"2024-04-27T05:13:01Z","timestamp":1714194781000},"page":"857-869","source":"Crossref","is-referenced-by-count":19,"title":["Monitoring fatigue state with heart rate\u2010based and subjective methods during intensified training in recreational runners"],"prefix":"10.1002","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4819-0619","authenticated-orcid":false,"given":"Olli\u2010Pekka","family":"Nuuttila","sequence":"first","affiliation":[{"name":"Faculty of Sport and Health Sciences University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"},{"name":"The UKK Institute for Health Promotion Research  Tampere Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arja","family":"Uusitalo","sequence":"additional","affiliation":[{"name":"Department of Sports and Exercise Medicine, Clinicum University of Helsinki  Helsinki Finland"},{"name":"Helsinki Clinic for Sports and Exercise Medicine Foundation for Sports and Exercise Medicine  Helsinki Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veli\u2010Pekka","family":"Kokkonen","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nilushika","family":"Weerarathna","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heikki","family":"Kyr\u00f6l\u00e4inen","sequence":"additional","affiliation":[{"name":"Faculty of Sport and Health Sciences University of Jyv\u00e4skyl\u00e4  Jyv\u00e4skyl\u00e4 Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,4,26]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0139754"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.2015\u20100495"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40279\u2010020\u201001269\u2010w"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1249\/mss.0000000000002095"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/bf00422166"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsm.2007.042200"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1123\/ijspp.2022-0417"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsams.2018.01.008"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2014.00073"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/17461391.2018.1458907"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1249\/mss.0000000000001725"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsams.2021.04.012"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1139\/apnm\u20102012\u20100203"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1079\/bjn19670070"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40798\u2010022\u201000523\u2010x"},{"issue":"6","key":"e_1_2_7_17_1","first-page":"370","article-title":"Athletic Performance in Relation to Training Load","volume":"95","author":"Foster C.","year":"1996","journal-title":"Wisconsin Medical Journal"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1249\/01.mss.0000147588.28955.48"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.3389\/fspor.2022.1013360"},{"issue":"2","key":"e_1_2_7_20_1","first-page":"627","article-title":"Receiver Operating Characteristic (ROC) Curve Analysis for Medical Diagnostic Test Evaluation","volume":"4","author":"Hajian\u2010Tilaki K.","year":"2013","journal-title":"Caspian Journal of Internal Medicine"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1249\/mss.0000000000000177"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.23736\/s0022\u20104707.18.08195\u20101"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1249\/00005768\u2010199501000\u201000019"},{"key":"e_1_2_7_24_1","first-page":"1","article-title":"How to Interpret Changes in an Athletic Performance Test","volume":"8","author":"Hopkins W.
