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.
Over Our Heads
June 29, 2012
In last month’s Wired magazine, Vint Cerf of Google cites American computer scientist Alan Kay’s comment, “The best way to predict the future is to invent it.”
Wired’s Thomas Goetz writes, “Too much of the technology world is trying to build clever solutions to picayune problems.” (A quick look at the more than 1.2 million mobile phone applications available free or for sale in our world today – growing by 2,500 per day – makes the observation abundantly clear that many great minds are being wasted on the mundane, silly apps that do nothing to improve the quality of life for humankind.)
Goetz would have these talents aimed at much higher order needs of society. “These times especially call for more than mere incrementalism. Let’s demand that our leaders get in over their heads, that they remain a little bit naïve about what they’re getting into.”
And what might “going beyond incrementalism” look like for us in school sports? Well, on just one topic – health and safety – it might mean, as provocative samples to stimulate bigger and better ideas:
-
Restricting kickoff returns, punt returns and interception returns in football – the three most dangerous times for players.
-
Reducing heading of the ball in soccer to reduce the effects of repeated blows to the brain.
-
Requiring all head coaches to complete CPR training, and requiring all coaches on all levels to complete an online coaching fundamentals course within their first two years of coaching.
-
Presenting an AED with every MHSAA tournament trophy – District, Regional and Final, for both champion and runner-up – during each of the next four years.
In any event, we need to avoid the distraction of meaningless matters and fix our focus on larger issues, and risk raising ideas and making changes that could have more lasting impact than incremental changes. Just talking about these things begins to send messages that improve school sports. Doing some things like them would actually invent our future.
