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.

Double Win Practice Policies

February 22, 2013

The MHSAA’s third health and safety thrust for the next four years focuses on practice rules, especially early in the fall season.

Here we will be especially interested in finding “double wins,” that is, policies that simultaneously enhance acclimatization and reduce head contact.

In football, for example, this could mean increasing the number of days without protective pads before the first practice in full pads.  Michigan requires three days, but there’s a trend toward four or five days in other states.

Football might also limit any day to a single practice in pads, following the lead of colleges and a growing number of state high school associations that are restricting two-a-day practices in pads on the same day or on consecutive days.

Both of these changes could make acclimatization more gradual and healthy, and reduce the occurrences for contact to the head:  two priorities as practice policies are reviewed and revised.

The MHSAA’s sport committees, sometimes with their work augmented by that of special task forces, are being charged with these responsibilities.
