A state-mandated study of high school athletes' concussions was unveiled Thursday at the State Department of Health. The Legislature required the study in a 2011 bill.
The study said that athletic trainers from 36 Twin Cities Metro public high schools voluntarily reported 730 concussions. Researchers projected from that an estimated 3,000 concussions among the young athletes in the 2013-2014 school year.
"Football, which is the most heavily participated activity, accounted for 42% of the concussions in the Twin Cities," said Dr. Ed Ehlinger, Minnesota Commissioner of Health. "However, girls and boys hockey had similar rates of concussion (to football). In sports played by both boys and girls in Minnesota, the rate of concussion among girls is higher than among boys, which mirrors national data on that subject."
