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.
Bubble Wrap
October 28, 2014
We must do everything we can do to minimize serious injuries in school sports; but because the benefits of school sports participation are so universal and serious injuries so unusual, we should accompany our continuing campaigns for safety with constant appeals for common sense.
It is a compliment to school sports that each and every one of the very rare number of school sports-related deaths carries with it great sorrow and scrutiny. Nationwide there are so few tragedies that schools treat all of them with tenderness; and we try to learn from each of them how to have fewer of them.
But the attention we give to increased safety should not outshout the safety record we already have in school sports, especially compared to activities that lead to far more deaths with far less attention. For example, each year . . .
- 20 skateboarding deaths;
- 40 skiing deaths;
- 400 youth drownings; and
- 700 bicycling deaths.
Compared to school sports, these numbers are epidemics; and compared to school sports, these epidemics are ignored.
Our world is not bubble wrapped, nor should it be. School sports is not 100 percent injury-free, nor can it be. We should work to make school sports still safer, and work almost as hard to explain how safe school sports already is.
