However, there have been no reports of large-scale SRC studies among soccer players in Japan. The purpose of this study is to investigate the epidemiology of SRC among university soccer players in Japan. This descriptive epidemiological study collected data on the history of SRC and details of SRC injuries during soccer. The participants were university male soccer players belonging to the Japan University Football Association. SRC rates were calculated per 1000 athlete-exposures (AEs). A total of 5953 students participated in this study. The SRC rate was 0.10\/1000 AE during total activities. The SRC rate during competition (0.42\/1000 AE) was higher than in practice (0.04\/1000 AE). The most frequent mechanism of SRC was \u201chead-to-head\u201d (26.9%), followed by \u201chead-to-ball\u201d (24.2%). During competition, the most frequent mechanism was \u201chead-to-head\u201d (30.8%), followed by \u201chead-to-ground\u201d (23.8%), and \u201chead-to-ball\u201d (19.3%) followed, while in practice, it was \u201chead-to-ball\u201d (34.8%), followed by \u201chead-to-ground\u201d (23.8%), and \u201chead-to-head\u201d (17.2%). Thus, there was a difference in the mechanism of injury between competition and practice. In this study, among Japanese university soccer players, the SRC rate was to be approximately ten times higher in competition than in practice.<\/jats:p>","DOI":"10.3390\/brainsci14080827","type":"journal-article","created":{"date-parts":[[2024,8,19]],"date-time":"2024-08-19T07:37:21Z","timestamp":1724053041000},"page":"827","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Epidemiology of Sports-Related Concussion in Japanese University Soccer Players"],"prefix":"10.3390","volume":"14","author":[{"given":"Hiroshi","family":"Fukushima","sequence":"first","affiliation":[{"name":"National Institute of Technology, Kurume College, Fukuoka 830-8555, Japan"},{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yutaka","family":"Shigemori","sequence":"additional","affiliation":[{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"},{"name":"Faculty of Sports Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shunya","family":"Otsubo","sequence":"additional","affiliation":[{"name":"Center for Education and Innovation, Sojo University, Kumamoto 860-0082, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyosuke","family":"Goto","sequence":"additional","affiliation":[{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"},{"name":"Department of Rehabilitation, Fukuoka University Hospital, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koki","family":"Terada","sequence":"additional","affiliation":[{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Muneyuki","family":"Tachihara","sequence":"additional","affiliation":[{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatsuma","family":"Kurosaki","sequence":"additional","affiliation":[{"name":"Department of Health Sports Communication, Faculty of Human Sociology, Kobe University of Welfare, Hyogo 679-2217, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keita","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nana","family":"Otsuka","sequence":"additional","affiliation":[{"name":"Faculty of Sports Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kentaro","family":"Masuda","sequence":"additional","affiliation":[{"name":"Graduate School of Sports and Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6867-6387","authenticated-orcid":false,"given":"Rino","family":"Tsurusaki","sequence":"additional","affiliation":[{"name":"Faculty of Human Sciences, Kyushu Sangyo University, Fukuoka 813-0004, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Inui","sequence":"additional","affiliation":[{"name":"Faculty of Sports Health Science, Fukuoka University, Fukuoka 814-0180, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,8,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"27","DOI":"10.1080\/00913847.1995.11947799","article-title":"Second impact syndrome: A risk in any contact sport","volume":"23","author":"Cantu","year":"1995","journal-title":"Physician Sports Med."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2549","DOI":"10.1001\/jama.290.19.2549","article-title":"Cumulative effects associated with recurrent concussion in collegiate football players: The NCAA Concussion Study","volume":"290","author":"Guskiewicz","year":"2003","journal-title":"JAMA"},{"key":"ref_3","first-page":"31","article-title":"Cerebral concussion amoncompetitionrican football players in Japan: 10-year survey in a high school football team","volume":"47","author":"Yamamoto","year":"2005","journal-title":"Nihon Univ.
