The number of concussions suffered by high school athletes in Michigan continues to fall. In its third annual report, the Michigan High School Athletic Association says concussions were down 10% in the most recent school year compared to the one prior, and they were down 19.6% from the first year of the study. Football had the most per 1,000 athletes, but the MHSAA notes girls reported three-times more concussions than boys in the same sport. Boys, though accounted for two-thirds of all the head injuries due to playing more contact sports. Varsity athletes suffered 56% of the concussions, and the MHSAA says the majority happened during games.
