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.
A Game Changer
July 9, 2012
In the year 2000, fewer than 300,000 books were published in the United States. In 2010, more than a million were published.
This means that electronic media didn’t kill the book publishing industry, as some experts predicted. Quite the opposite. But electronic media surely changed the industry in several major ways, including:
-
It democricized the industry – made it cheaper and easier for almost all of us to publish whatever we want, whenever we want, even if only our family and closest friends might read it.
-
It dumbed down the industry. With almost everybody able to produce almost anything, the average quality of published works has plummeted.
The importance of these book industry statistics to us is that they point to what can and does happen in other aspects of life, including school sports. They provide evidence that sometimes what we think might crush us, only changes us. Causes us to do things differently – cheaper, faster or better and, sometimes, all three at once.
Some of us in school sports may, sometimes, curse electronic media; but many of the changes they have brought us are positive. Like officials registering online, receiving game assignments online and filing reports online. Like schools rating officials online; and online rules meetings for coaches and officials. Like schools scheduling games online, and spectators submitting scores online. Like the ArbiterGame scheduling program the MHSAA is now providing all its member high schools free of charge.
