Incidence rates (IRs; number of potential head injuries per 1000 match\u2010hours) were reported separately for each discipline based on official and total exposure times (the duration from initial to final whistle).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 395 potential head injuries were identified: 186 (IR:85.8\/1000 match\u2010hours) in football, 86 (IR:247.8) in futsal and 123 (IR:627.5) in beach soccer. After exposure adjustment, IRs were 76.4, 122.3 and 383.2, respectively. Direct opponent contact was the main mechanism for all disciplines (football 81.5%, futsal 76.2%, beach soccer 78.9%). Unintentional ball\u2010to\u2010head impacts accounted for 6% of cases (football), 16.7% (futsal), and 13.8% (beach soccer). In beach soccer, 17.9% of injuries were associated with overhead kicks. Visible signs of a possible concussion were observed in 16.3% of cases (football), 9.5% (futsal) and 20.3% (beach soccer).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Incidence and patterns of potential head injuries differ across football, futsal and beach soccer, underscoring the need for individual recognition in all three disciplines. Ball\u2010related impacts contributed significantly to the differences in IRs and overhead kicks posing a unique risk in beach soccer. Targeted preventive strategies, such as specific drills on safe blocking in futsal, and training to improve the safe execution of overhead kicks in beach soccer, may help reduce these risks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n                    <jats:p>N\/A.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/ksa.70158","type":"journal-article","created":{"date-parts":[[2025,10,28]],"date-time":"2025-10-28T13:20:39Z","timestamp":1761657639000},"page":"1107-1117","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Potential head injuries in men's football, futsal and beach soccer: Distinct exposure\u2010adjusted frequency and patterns from a comparative video analysis"],"prefix":"10.1002","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5429-1905","authenticated-orcid":false,"given":"Yavuz","family":"Lima","sequence":"first","affiliation":[{"name":"Department of Sports Medicine, \u0130stanbul University\u2010Cerrahpasa Cerrahpasa Faculty of Medicine \u0130stanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Levend","family":"Kara\u00e7oban","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Ankara University Faculty of Medicine Ankara Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Serner","sequence":"additional","affiliation":[{"name":"FIFA Medical, F\u00e9d\u00e9ration Internationale de Football Association Zurich Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kerry","family":"Peek","sequence":"additional","affiliation":[{"name":"FIFA Medical, F\u00e9d\u00e9ration Internationale de Football Association Zurich Switzerland"},{"name":"School of Health Sciences, Faculty of Medicine and Health The University of Sydney  Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Og\u00fcn","family":"K\u00f6ya\u011fas\u0131o\u011flu","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, \u0130stanbul University\u2010Cerrahpasa Cerrahpasa Faculty of Medicine \u0130stanbul Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,10,27]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjopen-2018-024607"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/24733938.2024.2372304"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tjem.2018.08.001"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-097217"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1089\/neu.2016.4767"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/JSM.0000000000001044"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2019-100628"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2022-106656"},{"key":"e_1_2_10_10_1","unstructured":"FIFA.
