Evaluation of head impact exposure measured from youth football game plays.

Objective: There is a growing body of literature informing efforts to improve the safety of football; however, research relating on-field activity to head impacts in youth football is limited. Therefore, the objective of this study was to compare head impact exposure (HIE) measured in game plays among 3 youth football teams.

Methods: Head impact and video data were collected from athletes (ages 10-13 years) participating on 3 youth football teams.
