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.
Our Laboratory
June 30, 2014
Failure: Lab is a speaker-audience experience modeled after TED (Technology, Entertainment, Design); but unlike TED’s frequent focus on success stories, Failure: Lab showcases stories of failure – and it instructs speakers not to provide lessons learned. Figuring out those lessons is the role of the audience, not the presenters.
Of course, one of life’s most bountiful laboratories of failure is sports. At least 50 percent of the participants in any athletic contest do not win. Sometimes it’s just one competitor out of 10 or 100 or 1,000 who wins.
In MHSAA tournaments, all but one team in each class or division ends the season with a loss. In basketball this past winter, only four of 729 high schools that sponsored boys varsity basketball ended the season with a victory.
It’s a fact; sports is a failure lab.
In the spirit of Failure: Lab, I won’t offer a defense or an explanation of the lessons learned. You’re the audience; you figure it out. Why do we go to so much time and effort to create this laboratory?
