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.

Football Practice Proposals

June 11, 2013

During 2013, a Football Task Force has been working on revisions to practice policies that might simultaneously improve acclimatization of players and reduce head trauma. Over three meetings, the following four-part recommendation has been developed:

  1. During the first week of practice of the season, only helmets are allowed the first two days, only shoulder pads may be added on the third and fourth days, and full pads may not be worn until the fifth day of team practice.
  2. Before the first regular-season game, schools may not schedule more than one “collision” practice in a day.
    • A “collision” practice is one in which there is live, game-speed, player-vs.-player contact in pads (not walk-throughs).
    • During any additional practice sessions that day, players may wear helmets and other pads (neither is mandatory). Blocking and tackling technique may be taught and practiced. However, contact is limited to players vs. pads, shields, sleds or dummies.
  3. After the first regular-season game, teams may conduct no more than two collision practice days in any week, Monday through Sunday. During other days of practice, players may wear helmets and other protective pads (neither is mandatory). Blocking and tackling technique may be taught and practiced.  However, contact is limited to players vs. pads, shields, sleds or dummies.
  4. No single practice may exceed three hours, and the total practice time for days with multiple practice sessions may not exceed five hours.
    • Warm-up, stretching, speed and agility drills and cool down are all considered part of practice. Neither strength/weight training activities nor classroom sessions are considered practice for the purposes of the three- or five-hour limits.

MHSAA staff will be taking this recommendation on the road from now through October to obtain constituent understanding and feedback. It is the intent of the Task Force to finalize its consensus regarding these matters by late November so they may be reviewed by the Michigan High School Football Coaches Association, the MHSAA Football Committee and at the MHSAA League Leadership meeting prior to Representative Council action in March 2014.
