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.

Ready for Some Football

August 12, 2014

How seriously should we take public criticism of tackle football when that public promotes boxing or cage fighting? Or how seriously should we take public criticism of football played with helmets when that public allows motorcyclists to ride without any helmets at all?

This fickle if not hypocritical focus on football deserves to be exposed. 

However, and more importantly, this does not reduce our obligation to rise above the obvious questions of fair and balanced criticism and keep pressing for a safer environment for schools’ most popular participation sport.

In Michigan this has led to new limitations on head-to-head contact in football practices that began for more than 600 high schools this week. Specifically, no team or individual may participate in more than one collision practice per day before the first game, and no more than two collision practices per week after the first game.

The new policies promote instruction in proper blocking and tackling technique. It is full speed head-to-head contact that is further reduced, not full speed shoulder contact with sleds, shields and dummies nor slow speed contact between players.

Last month, and perhaps two years too late to be helpful, the National Federation of State High School Associations hosted a high-profile, high-powered summit to discuss practice policies of the kind that we developed, debated and adopted during the past school year to be ready for this 2014 season.
