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.

Classes or Divisions

April 4, 2014

Never is the continuous cycle of school sports more obvious to me than at this time of year. Just as winter tournaments conclude for 2013-14, we post the classifications and divisions for MHSAA tournaments in 2014-15.

Unlike many states which reclassify every two, three or four years, we collect enrollment figures each year and redraw the lines between Classes A, B, C and D each year in late March. And for all sports except basketball and volleyball, we place an almost equal number of schools that actually sponsor the sport into equal divisions – usually four divisions, but fewer for sports that are sponsored by a relatively small number of schools.

This traditional treatment of boys and girls basketball and girls volleyball – continuing with four classes rather than four divisions with an equal number of schools that actually sponsor the sport in each division – reflects that when last considered for change 17 years ago, there wasn’t much difference in the number of schools in the four classes vs. the four equal divisions in these three tournaments.

For 2014-15, of the 749 MHSAA member schools, 724 indicate they sponsor boys basketball, 716 sponsor girls basketball and 704 sponsor girls volleyball. (Among the sports in equal divisions, the most populous is baseball with 630 sponsoring schools.)

Last January, the MHSAA Classification Committee requested that staff provide the Representative Council what the numbers would look like for 2014-15 if these three sports were in “equal divisions” like other sports. The Classification Committee wasn’t recommending any change – just asking that the Representative Council see the numbers again.

  • In boys basketball, the number of schools in Divisions 1, 2, 3 and 4 would be 181, compared to 188, 182, 182 and 172 in Classes A, B, C and D, respectively.
  • In girls basketball, the number of schools in Divisions 1, 2, 3 and 4 would be approximately 179, compared to 186, 181, 182 and 167 in Classes A, B, C and D, respectively.
  • In girls volleyball, the number of schools in Divisions 1, 2, 3 and 4 would be approximately 176, compared to 186, 178, 180 and 160 in Classes A, B, C and D.

Obviously, every time more schools are placed in a division, the enrollment range between the largest and smallest school of that division expands. Therefore, a change to equal divisions places more schools and expands the enrollment range in the division of schools where enrollment spreads have the greatest impact - Division 4. It was our smallest schools that least liked the change to equal divisions in other sports 17 years ago. They would be the dissenters to this change for basketball and volleyball today.
