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.
Fundamentals vs. Fads
July 9, 2013
During the summer weeks, "From the Director" will bring to you some of our favorite entries from previous years. Today's blog first appeared Aug. 9, 2011.
While examining some ancient fabrics at the Viking Ship Museum in Oslo, Norway, my wife explained to me the “warp and weft” of weaving – how the vertical fibers are the warp and the horizontal fibers are the weft.
What intrigued me about the ancient remnants was that the vertical fibers of wool had survived the centuries so much better than the left-to-right-fibers of linen and silk. I was informed that the vertical fibers (the warp) gave the fabric its durability, while the horizontal fibers (the weft) provided the design. And the strength lasted long after the color had faded.
My vacationing mind then jumped quickly across the ocean and centuries to my working preoccupation with the essentials of school-based sports. I reflected on how certain principles on which educational athletics are based have withstood challenge after challenge over time, even as some of the earlier features of school sports have faded.
This travel memory will serve as a reminder to me to focus on the fundamentals – on those core values of school sports that are essential and allow us to claim that the programs are educational – and to worry less about the superficial features that will inevitably change with the trends and fads over the years. Determining which is which – distinguishing fundamentals from fads – is one of the challenges the leaders of school sports must face.
