Methods<\/jats:bold>:<\/jats:italic> Data were collected across 5 games during the 2016 Rio Olympic Games. Global positioning system units (10\u00a0Hz) were used to assess the running demands, accelerations, and decelerations of outfield players in a men\u2019s hockey squad with matches 2 to 5 compared with match 1. CK was used as a marker of muscle damage, and self-reported psychometric questionnaires were used to assess wellness, with each of the 5 matches compared with precompetition assessments. Results<\/jats:bold>:<\/jats:italic> There were significant increases (P<\/jats:italic>\u2009<\u2009.05) in either, or both, absolute and relative total distance, player load, high-speed running distance, sprint distance, and accelerations and decelerations, compared with baseline. There was a significant decrease (P<\/jats:italic>\u2009<\u2009.05) in maximal velocity by match 5. CK significantly increased from match 1 to 5 and displayed significant correlations with total distance (r<\/jats:italic>\u2009=\u2009.55) and player load (r<\/jats:italic>\u2009=\u2009.41). Muscle soreness correlated with total distance and player load, with other wellness markers unchanged compared with baseline. Conclusions<\/jats:bold>:<\/jats:italic> International hockey athletes may maintain or increase running activities over the course of an Olympic tournament; however, this may be impacted by situational (match score\/outcome) and environmental (ambient temperature) factors. Despite CK and muscle soreness displaying relationships with running variables, further work is needed to establish their individual value in monitoring international hockey athletes.<\/jats:p>","DOI":"10.1123\/ijspp.2020-0698","type":"journal-article","created":{"date-parts":[[2021,3,10]],"date-time":"2021-03-10T14:24:53Z","timestamp":1615386293000},"page":"1393-1400","source":"Crossref","is-referenced-by-count":5,"title":["Running Performance Is Correlated With Creatine Kinase Levels and Muscle Soreness During an Olympic Games in Hockey"],"prefix":"10.1123","volume":"16","author":[{"given":"Gerard E.","family":"McMahon","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lee-Ann","family":"Sharp","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rodney A.","family":"Kennedy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"3","key":"r1","series-title":"Int J Sports Physiol Perform","first-page":"224","article-title":"GPS analysis of an international field hockey tournament","volume":"7","author":"Jennings D","year":"2012","unstructured":"Jennings D, Cormack SJ, Coutts AJ, Aughey RJ.
