Abstract
There has been increasing concern, particularly in the US, about potential long-term neurological deterioration syndromes seen in the US football players. Recurrent concussions are a potential area of concern. The authors of this paper have used data bases from three levels of amateur US football to identify the rate and risk of concussion injury in both football games and practice at the youth, high school, and college levels. This information is very important initial data around concussion rates at these levels.
