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.
Heads and Heat
August 16, 2012
We are engaged in very serious discussions. They’re not only complicated, with unintended negative consequences possible from what are thought to be positive actions; they’re also a matter of life and death.
The topic is football – the high school sport under most scrutiny today and suffering from the most criticism it’s seen since the 1970s when catastrophic neck injuries spiked, liability awards soared, many insurers balked, and most helmet manufacturers abandoned the business altogether.
During recent years we have learned about the devastating long-term effects of repeated blows to the head; and we’re trying to reduce such hits. We’ve learned that 70 percent of concussions in football result from helmet-to-helmet contact, and we’re trying to have coaches teach blocking and tackling differently and have officials penalize “high hits” consistently and rigorously.
During the past several years we’ve learned that serious heat illness and heat-related deaths are 100 percent preventable, yet nationwide there were 35 heat-related deaths in high school football alone from 1995 to 2010; and we’re promoting practices that acclimatize athletes more gradually than “old school” traditionalists might advocate.
As we simultaneously address issues of heads and heat in football, some coaches may think we’re being overbearing, while many in medical fields say we’re out of date, citing higher standards of the American Academy of Pediatrics, National Athletic Trainers Association and National Federation of State High School Associations, as well as many of our counterpart organizations across the country.
As we consider in-season changes to improve athlete acclimatization and reduce blows to the head, we should be open to making out-of-season changes that work toward rather than in opposition to those objectives. There can be no sacred cows. The topic is too serious.
Ultimately, if we err in the outcome of this year’s discussions about heads and heat in football, it must be on the side of safety, on minimizing risks for student participants. They deserve it and, once again, the sport of football needs it.
