Video analysis of head impact parameters in youth football.

This study presents findings from a descriptive video analysis of in-game head impacts in youth football. Parameters detailing each head impact (e.g., frequency, type, mechanism, source, location, etc.) were reviewed and documented for three different age groups (≤ 12 years). A trend towards youth players sustaining a high frequency of head-to-ground impacts was shown, specifically when engaged in tackling attempts. Helmet impact locations also differed between each age group, suggesting that progression in tackling technique may affect head impacts observed. This work highlights the importance of video as an effective tool for investigating head impact biomechanics in football, especially at the youth level of play.
