Methods<\/jats:bold>:<\/jats:italic> Fifty male athletes were monitored daily during the 28\u00a0weeks of the regular season using well-being and sleep surveys. On-ice external TL was monitored using portable inertial measurement units during practices and matches. Linear mixed-effects models were applied to evaluate whether well-being perception (ie,\u00a0pain, nutrition, stress, and rest) and external TL may affect sleep quality and quantity. Results<\/jats:bold>:<\/jats:italic> High levels of well-being positively affected sleep duration and quality (P<\/jats:italic>\u2009<\u2009.001), whereas high-intensity TL had a detrimental impact on sleep duration (P<\/jats:italic>\u2009=\u2009.007). Moreover, away and evening matches had a detrimental effect on sleep quantity and quality (P<\/jats:italic>\u2009<\u2009.001). Finally, a high match on-ice load per minute had a negative association with sleep quality (P<\/jats:italic>\u2009=\u2009.04). Conclusions<\/jats:bold>:<\/jats:italic> Findings indicate that well-being and high-intensity trainings can impair sleep duration and quality. In addition, high-intensity match load, away matches, and evening matches can impair postmatch sleep. Therefore, monitoring well-being in conjunction with TL is essential to understand sleep disturbances in athletes. Practitioners should also implement sleep hygiene strategies that facilitate longer time in bed after high-intensity, away, and evening matches to help athletes recover.<\/jats:p>","DOI":"10.1123\/ijspp.2022-0256","type":"journal-article","created":{"date-parts":[[2023,2,8]],"date-time":"2023-02-08T13:42:29Z","timestamp":1675863749000},"page":"363-367","source":"Crossref","is-referenced-by-count":5,"title":["Association Between Variations in Training Load, Sleep, and the Well-Being of Professional Hockey Players"],"prefix":"10.1123","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7365-5097","authenticated-orcid":true,"given":"Am\u00e9lie","family":"Apinis-Deshaies","sequence":"first","affiliation":[{"name":"School of Kinesiology and Exercise Science, Faculty of Medicine, Universit\u00e9 de Montr\u00e9al, Montreal, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3477-9783","authenticated-orcid":true,"given":"Maxime","family":"Trempe","sequence":"additional","affiliation":[{"name":"Department of Sport Studies, Bishop\u2019s University, Sherbrooke, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5160-0012","authenticated-orcid":true,"given":"Jonathan","family":"Tremblay","sequence":"additional","affiliation":[{"name":"School of Kinesiology and Exercise Science, Faculty of Medicine, Universit\u00e9 de Montr\u00e9al, Montreal, QC, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"issue":"4","key":"r1","series-title":"Rev Neurosci","first-page":"375","article-title":"The mystery of sleep function: current perspectives and future directions","volume":"17","author":"Frank MG","year":"2006","unstructured":"Frank MG.
