After both the first and second years of collecting head injury reports from all Michigan High School Athletic Association member high schools for all practices and events in MHSAA sports, we cautioned people to refrain from making too many conclusions.
It’s too soon. We now have a baseline, but we will need several years before we can be certain that we’ve spotted trends or trouble spots.
Nevertheless, one observation screams out. Girls report two to three times the number of concussions that boys do. In basketball, soccer, and in softball compared to baseball, girls report two to three times as many concussions. That was true in year one; it remained true in year two.
It may be that girls sustain more concussions than boys, or that girls are more forthcoming in reporting than boys are, or both. In the past, researchers have published both conclusions.
In either case, it means we need to coach boys and girls differently, and we need to prepare coaches differently for boys and girls teams, as we are doing in the MHSAA Coaches Advancement Program.
