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.

Rocket Science

January 5, 2015

I have always been fascinated by space exploration and in awe of all that is required and must go right to send a space vehicle atop a multi-stage booster rocket from a moving object like Earth, and land it softly on another moving object like the moon or Mars or most recently a massive rock, after a journey of many months and millions of miles. How can people figure that stuff out?

There cannot be a problem of school sports that is more complicated than those of space exploration, except for one feature – which is that our problems deal with people, who are far less predictable and dependable than the laws of physics.

Making matters worse is that we are working with people in a competitive arena, and in an emotional setting, where the objectivity which characterizes the scientific method of rocket scientists is generally if not universally absent.

As long as potential problem-solvers view potential solutions through the lens of what does or does not benefit them in terms of competitive edge, our efforts to make good changes will never launch or, if launched, will miss the target.
