Nine weightlifters (21\u2009\u00b1\u20090.5 years) performed, in a randomized order, three Olympic-Weightlifting sessions (i.e., at 08:00, 14:00, and 18:00). Blood samples were collected at rest, 3\u00a0min and 48\u00a0h after each training session. Between pre- and post-training session, ANOVA showed significant increases in oxidative stress markers at the three TODs (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01) and significant increases for creatine kinase (CK) and lactate dehydrogenase (LDH) only at 08:00 and 18:00 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). At rest, the results showed a significant diurnal variation for the majority of the selected parameters except for malondialdehyde (MDA), total bilirubin, and CRP with higher values observed at 18:00 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05). After the training session, given the higher rate of increase during the morning session, these diurnal variations persisted for temperature and WBC (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01) and were suppressed for CK, LDH, uric acid (UA), catalase, and glutathione peroxidase. The main significant correlations (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001) were observed between: (1)\u00a0CK and MDA (<jats:italic>r<\/jats:italic>\u2009=\u20090.6) and CK and UA (<jats:italic>r<\/jats:italic>\u2009=\u20090.66 and <jats:italic>r<\/jats:italic>\u2009=\u20090.82) during the morning and evening training sessions; (2)\u00a0CK and CRP only during the morning session (<jats:italic>r<\/jats:italic>\u2009=\u20090.5); and (3)\u00a0CRP and WBC during the three training sessions (<jats:italic>r<\/jats:italic>\u2009=\u20090.8). In conclusion, the present findings: (1)\u00a0confirm that the muscle damage responses could be induced by a high level of oxidative stress and (2)\u00a0suggest to avoid scheduling training sessions in the morning given the higher muscle damage, inflammatory, and oxidative responses at this TOD.<\/jats:p>","DOI":"10.1556\/036.103.2016.2.11","type":"journal-article","created":{"date-parts":[[2017,8,18]],"date-time":"2017-08-18T06:42:37Z","timestamp":1503038557000},"page":"243-261","update-policy":"https:\/\/doi.org\/10.1556\/policypage.crossmark.crossref.2","source":"Crossref","is-referenced-by-count":21,"title":["Relationship between biomarkers of muscle damage and redox status in response to a weightlifting training session: effect of time-of-day"],"prefix":"10.1556","volume":"103","author":[{"given":"A","family":"Ammar","sequence":"first","affiliation":[{"name":"Research Unit: Education, Motricity, Sport and Health, High Institute of Sport and Physical Education of Sfax, Sfax University, Sfax, Tunisia"},{"name":"Institute of Sport Science, Otto-von-Guericke-University Magdeburg, Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H","family":"Chtourou","sequence":"additional","affiliation":[{"name":"Research Unit: Education, Motricity, Sport and Health, High Institute of Sport and Physical Education of Sfax, Sfax University, Sfax, Tunisia"},{"name":"High Institute of Sport and Physical Education of Sfax, Sfax University, Sfax, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O","family":"Hammouda","sequence":"additional","affiliation":[{"name":"Research Center on Sport and Movement (CeRSM, EA 2931), Sciences and Techniques of the Physical and Sporting Activities (UFR STAPS), University of Paris Ouest Nanterre La Defense, Nanterre, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Turki","sequence":"additional","affiliation":[{"name":"Laboratory of Biochemistry, CHU Habib Bourguiba, Sfax University, Sfax, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F","family":"Ayedi","sequence":"additional","affiliation":[{"name":"Laboratory of Biochemistry, CHU Habib Bourguiba, Sfax University, Sfax, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Kallel","sequence":"additional","affiliation":[{"name":"Laboratory of Hematology, CHU Habib Bourguiba, Sfax University, Sfax, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O","family":"AbdelKarim","sequence":"additional","affiliation":[{"name":"Institute of Sport Science, Otto-von-Guericke-University Magdeburg, Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Hoekelmann","sequence":"additional","affiliation":[{"name":"Institute of Sport Science, Otto-von-Guericke-University Magdeburg, Magdeburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N","family":"Souissi","sequence":"additional","affiliation":[{"name":"National Sport Observatory, Tunis, Tunisia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"425","container-title":["Acta Physiologica Hungarica"],"original-title":[],"link":[{"URL":"http:\/\/www.akademiai.com\/doi\/full-xml\/10.1556\/036.103.2016.2.11","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/akjournals.com\/view\/journals\/036\/103\/2\/article-p243.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/akjournals.com\/view\/journals\/036\/103\/2\/article-p243.xml","content-type":"text\/html","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/akjournals.com\/view\/journals\/036\/103\/2\/article-p243.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,1,3]],"date-time":"2024-01-03T15:51:34Z","timestamp":1704297094000},"score":1,"resource":{"primary":{"URL":"https:\/\/akjournals.com\/view\/journals\/036\/103\/2\/article-p243.xml"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,6]]},"references-count":0,"journal-issue":{"issue":"2"},"URL":"https:\/\/doi.org\/10.1556\/036.103.2016.2.11","relation":{},"ISSN":["0231-424X","1588-2683"],"issn-type":[{"value":"0231-424X","type":"print"},{"value":"1588-2683","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,6]]}}}
