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.

Specialization Risks

July 21, 2014

Another informed and influential voice has joined our frequent refrain that sports specialization is rarely in a student’s best interest.

David Epstein, author of The Sports Gene, offered an opinion piece for the New York Times last month that “hyper-specialization . . . is both dangerous and counterproductive.”

Epstein described the results of a three-year study at Loyola University of Chicago that found highly specialized youth had a 36 percent increased risk of suffering a serious overuse injury, including “stress fractures in their backs, arms and legs; damage to elbow ligaments; and cracks in the cartilage in their joints.”

Epstein continued: “Because families with greater financial resources were better able to facilitate the travel and private coaching that specialization requires, socio-economic status turned up as a positive predictor of serious injury.”

“In case health risks alone aren't reason enough for parents to ignore the siren call of specialization,” wrote Epstein, “diversification also provides performance benefits.” He cited “better learning of motor and anticipatory skills – the unconscious ability to read bodies and game situations – to other sports. They take less time to master the sport they ultimately choose.”
