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.

Classification Comparisons

January 27, 2012

One of the ways statewide high school organizations evaluate their operations is to compare their policies and  procedures with similar organizations.  We do so cautiously, however, because there are so many variables – like population and number of schools, as well as the size, shape and location of the state.

We find that the most useful comparisons are with states of the upper Midwest and Great Plains and, even more so, with the statewide organizations of that region with a number of schools closest to our approximately 765 member high schools in Michigan.

By these criteria, Illinois, with about 780 high schools, and Ohio, with about 820 high schools, are most valuable to observe, while neighbors like Indiana and Wisconsin with about 400 and 500 high schools, respectively, are less valid measures for our work here.

Recently, to help the MHSAA Classification Committee have a larger view of tournament classification systems, we provided the Volleyball, Football and Basketball Tournament classifications of Illinois and Ohio, as well as our own:

  • All three states have four classifications in both volleyball and basketball, and only Ohio equalizes the number of schools in each class/division (as Michigan does in all sports except volleyball and basketball).
  • The enrollment ranges between the largest and smallest schools in the classification for the largest schools and the classification for the smallest schools (Classes A and D in Michigan) are much smaller in Michigan than in either Illinois or Ohio in volleyball and basketball.
  • In football, Ohio’s playoffs accommodate 192 football schools in six divisions determined prior to the regular season, while both Illinois and Michigan’s 11-player playoffs accommodate 256 schools in eight divisions determined at the end of the regular season.
