College football players are more likely to suffer from a concussion during practice than they are during a live game, according to an observational study of NCAA Division I players showed. The study that looked at six NCAA football teams from 2015 to 2019 found that 72% of concussions and 67% of head impacts occurred during practices according to Michael McCrea, PhD of the Medical College of Wisconsin in Milwaukee, and co-authors.
In addition, preseason training accounted for half of all concussions even though it is only 21% of an entire season. The findings of this study could have an impact on the NCAA and on full-contact drills in the future.
