Differences between Canadian and American football could affect the magnitudes of head impacts and risk of concussion to Canadian players. This study sought to quantify and compare the number, magnitude, and location of impacts that Canadian University football players of different positions experienced during games and practice in a season. A kinematic measuring device collected the linear accelerations and rotational velocities of the head from impacts experienced by players competing in practices and games. The impact magnitudes that were experienced in games were significantly larger than in practice. The offensive back position and wide receiver position had significantly larger peak linear and rotational accelerations than the offensive linemen position. The magnitudes of impacts experienced by the wide receiver position in Canadian football were larger and not consistent with previous American studies, likely due to the pass style offence that is common in Canadian football. We observed that the head impact magnitudes vary by position, and session type in Canadian football.
