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.

The Off-Season

August 20, 2013

“If you take the summer off, you might have some muscle memory left, but you’re not going to be in the same shape.” That’s what Pam Allyn, director of LitWorld, a nonprofit organization promoting literacy, told Associated Press writer Philip Elliott for a recent story focusing on innovative ways to avoid the “brain drain” during summer vacations.

This gets to the heart of two points the MHSAA has been making.

First, the State of Michigan should stop penalizing public schools that want to begin academic classes prior to the Tuesday after Labor Day. Whether it’s a week, a month or longer, there should be incentives, not penalties, for doing more of what’s needed – providing more time on task.

Second, even for extracurricular sports, where programs begin before classes start in the fall and often extend beyond the end of classes in the spring, there is a need to rethink the summer months. Students need to stay active in a variety of activities during the summer to stay more fit, to help to enhance their acclimatization during early season practices in August and prevent injuries throughout the season.

From a sports perspective, the best summertime investments are to focus on strength and conditioning more than travel teams and tournaments, on variety more than specialization, and on engagement with friends who make the time fun. These are the elements of the “Prep Rally” promotion you can read about here.
