OBJECTIVE: To ascertain the epidemiology of @entity3681 in elite youth football. DESIGN: Retrospective analysis of prospectively collected injury data from English Football Association (FA) academies. SETTING: Forty-one FA football academies, between 1998 and 2006. @entity1 : For the complete seasons studied, a total of 14 776 players was registered from U9 to the @entity46164 age category, a mean of 2463 players per year. All @entity3681 of sufficient severity to miss 48 h or more of training were studied, 2563 @entity130 in total. MAIN OUTCOME MEASURE: The incidence and burden of @entity3681 in this population and factors associated with injury. RESULTS: There was a mean incidence of one @entity3681 per player per year, and a mean of 20 training days and two matches were missed per @entity3681 . @entity130 rates were seen in older players, in competition and later in each half of match time. @entity130 were observed early in the season and after the winter break. In competition, more @entity130 were associated with a contact situation than in training. Eighty-eight @entity130 (3.4%) required a lay-off of 3 months or more and in 18 (0.7%) cases the player failed to return to training. In total, 52 290 training days and 5182 match appearances were lost through @entity3681 . The majority of @entity130 were @entity6475 , but more severe @entity130 occurred accounted for 3.9% of the total. CONCLUSIONS: @entity3681 are common in young football players and are often severe, with prolonged loss of training time. This has potential far-reaching implications, both on and off the field.
