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.

The Specialty of School Sports

There is much finger pointing when it comes to sports injuries, and I’d like to point in a direction that is often missed.

Some people blame equipment – it’s either inadequate, or it’s so good that it encourages athletes to use their bodies in unsafe ways.

Some people say the rules are inadequate, or inadequately enforced by contest officials.

Some people say the pool of coaches is inadequate, or they are inadequately trained.

But let’s not miss the fact that risk of injury is inherent in athletic activities, and at least part of the reason injuries occur is because the participants are developmentally deficient. In fact, this may be the fastest growing contributing cause to injuries in youth sports. It’s not the sport; it’s the lack of development, the lack of physical preparation.

When rushed into early and intense specialization in a single sport, youth may not be ready for the rigors of that sport. Lindsay J. DiStefano, PhD, ATC, of the University of Connecticut, has researched the topic among youth basketball and soccer players and linked higher injury rates to lower sports sampling, and vice versa. Exposure to multiple sports during early childhood positively influences neuromuscular control and reduces injuries.

Do we encourage youth to sample several sports and help them learn basic athletic movements and skills? Do we offer opportunities to train and condition and focus special attention on strengthening knees and necks? Do we provide more time and attention on practice than on competition and assure safe technique is taught and learned?

Early and intense specialization, with excessive attention to competition, invites injury. There is a much healthier way for most youth – and that’s balanced, multi-sport participation – the specialty of junior high/middle school and high school sports.
