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.
Long-Term Investment
January 25, 2012
Many homes have just removed the decorations from their holiday trees and removed the bare, brittle tree from their house. This has caused me to reflect on a drive last fall through many miles of tree farms, observing some trees ready for harvest but many more trees that were many years away from cutting.
During that drive I thought about the character of those who had planted the trees. This is not like many crops which are planted in spring and provide a return on the investment by fall. One who plants trees knows the harvest is many years of growth and pruning away. That return on investment could be a decade or two of toil down the road.
As I questioned how these farmers could wait so long, I began to marvel at the optimistic, patient spirit they must have. Their hope and persistence. Their assurance that the time and money invested now will be rewarded later.
This humbling internal dialogue caused me to think of dedicated teachers, coaches and administrators who, metaphorically, are planting some trees and pruning others each and every school year, knowing they may never personally see the results. But having confidence that, in time, there will be a return on the investment they and their communities have made in our young people.
