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.

Permission to Disagree

February 17, 2015

An organization leader who is doing a good job works hard to provide the organization’s board of directors all the history and detail necessary to make good decisions. Questions and concerns are anticipated, and addressed in advance.

As a result of this good leadership, meetings usually run with efficiency, decisions are made without long discussions, and debate is infrequent and never contentious. Votes usually reflect unanimous agreement.

While these are traits of good organizational leadership, a tradition of great organizational dynamics is disagreement.

If the board is always in total agreement, then management is not bringing the board tough enough topics. The subjects are not serious enough. They are operational more than strategic; they are transactional, not transformational.

Among the current topics of school sports in Michigan are two upon which there is certain to be disagreement: (1) the role of 6th-graders in school sports and the MHSAA; and (2) out-of-season coaching rules. We see the lack of consensus at the local level and the league level and between different coaches associations. And we expect the Representative Council will lack unanimity if these topics ever arrive for the Council’s action.

These are large topics, worthy of our time because of the disagreement, not in spite of it.
