abstract="OBJECTIVES: To describe age group patterns for injury incidence, severity and burden  in elite male youth football. <br><br>METHODS: Prospective cohort study capturing data on  individual exposure and time-loss injuries from training and matches over four  seasons (2016/2017 through 2019/2020) at a national football academy (U13-U18; age  range: 11-18 years). Injury incidence was calculated as the number of injuries per  1000 hours, injury severity as the median number of days lost and injury burden as  the number of days lost per 1000 hours. <br><br>RESULTS: We included 301 players (591  player-seasons) and recorded 1111 time-loss injuries. Overall incidence was 12.0 per  1000 hours (95% CI 11.3 to 12.7) and burden was 255 days lost per 1000 hours (252 to  259). The mean incidence for overall injuries was higher in the older age groups  (7.8 to 18.6 injuries per 1000 hours), while the greatest burden was observed in the  U16 age group (425 days; 415 to 435). In older age groups, incidence and burden were  higher for muscle injuries and lower for physis injuries. Incidence of joint sprains  and bone stress injuries was greatest for players in the U16, U17 and U18 age  groups, with the largest burden observed for U16 players. No clear age group trend  was observed for fractures. <br><br>CONCLUSION: Injury patterns differed with age; tailoring  prevention programmes may be possible.
