Annual injury trends were evaluated by linear regression.</p><p><strong>Study design: </strong>Descriptive epidemiology study.</p><p><strong>Level of evidence: </strong>Level 3.</p><p><strong>Results: </strong>There were 2508 flag football injuries (NE, 86,443) analyzed from 2013 to 2022; 78.2% were sustained by male athletes. Linear regression analysis revealed no significant trend in annual injuries (<i>P</i> = 0.16) from 2013 to 2022. The most common mechanism of injury was player-player collision (35.7%). The 2 age groups most affected by flag football injuries were middle school-aged (11-13 years) (20.8%) and high school-aged (14-18 years) (23.7%). The area of the body most affected for pediatric (<18 years) groups was the head, while adults most frequently injured their fingers. In addition, the most common mechanism for the pediatric age group was fracture (21.3%), whereas adult age groups most frequently suffered from strain/sprain injuries.</p><p><strong>Conclusion: </strong>The number of injuries from flag football identified in this study has not decreased throughout the last decade, aside from 2020 - potentially due to the prevalence of COVID-19. Collisions were the most frequent mechanism of injury across all age groups. Whereas younger athletes frequently sustained head injuries and fractures, older athletes typically sustained strain/sprain injuries and finger injuries.</p>","PeriodicalId":54276,"journal":{"name":"Sports Health-A Multidisciplinary Approach","volume":" ","pages":"19417381251326575"},"PeriodicalIF":2.7,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11951116/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143722369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
