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.
No Further Review
December 15, 2015
The rise of instant replay came with the hope if not the promise that errors by officials could and would be corrected. Now we know those expectations are not being realized.
In many cases this fall, we have watched college and professional football instant replay officials stand by helplessly because the rules of replay would not permit them to change the call on the field. In many other cases, we have watched instant replay officials make wrong calls from the replay booth.
We have always known that the high school level would not be able to perform extensive instant replay review – we don’t have the number and quality of camera angles at our games to judge the plays. But now we know that the existence of such technology does not assure the accuracy of decision-making.
So, let the so-called higher levels interrupt and prolong their games with questionable procedures that are resulting in as much acrimony as accuracy. Turns out that on this matter, the high school level is lucky to lack the resources of the college and professional game. For us, there’s no need for further review of further review.
