Head Trauma and Learning
November 23, 2012
Researchers at my alma mater have joined their voices to the growing chorus of concerns about the effects of repeated blows to the head.
A study of the cognitive effects of head impacts on members of Dartmouth College football, hockey, track, crew and Nordic ski teams compared before and after season results on learning and memory skills. Participating athletes also came from Brown and Virginia Tech.
-
22 percent of athletes in contact sports had lower results on learning and memory skills tests after their season.
-
Only 4 percent of athletes in non-contact sports posted lower test results.
The researchers caution that it is unknown at this point how long these negative effects may last, but they also note there is some correlation between test results and how hard the athletes were hitting heads.
This adds to the mounting evidence that rules writers, program sponsors, coaches and officials must look for and implement a variety of measures to reduce the frequency and severity of head impacts in both practice and competition in all sports.
Show of Hands
July 12, 2017
Four dozen years ago, my boss, the executive director of the National Federation of State High School Associations, expressed to me his disappointment that one of the characteristics of NFHS national meetings was the much too frequent “show of hands.” That is, someone from one state would rise to ask for a show of hands on a topic: “How many states do this? ... How many states don’t? ... How many do that?”
My mentor’s point was that the time would be much better spent on a qualitative analysis of the topic, rather than a quantitative one ... a discussion of the merits of a particular policy or procedure, rather than a head count.
His message to me is recalled every time a proposal comes to the Michigan High School Athletic Association to change this or that policy and is accompanied by the meager rationale that it’s what 25 or 35 or 45 other states might do. That stat holds only mild interest for me.
Before we do anything here to be like anybody elsewhere, we need to measure the pros and cons in our place and time ... how it fits our culture or our climate, for example.
When we consider change in the start or end of seasons; or the number of interscholastic scrimmages or contests in a day, week or season; or the number of exceptions to the transfer rule or the length of ineligibility when no exception applies; or the number of classes or divisions for tournaments; or the existence or extent of seeding for a tournament; when we consider any of these things in Michigan, we need much better rationale than a show of hands.
