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.
Data is Due
December 4, 2015
Allow me to wander way outside my expertise for a moment … to quantum physics. I believe this is the discipline where it is said that “something doesn’t exist until it is described and measured.”
This statement embodies one of the reasons the MHSAA has mandated that, beginning this school year, member schools must report all possible head injuries in the practices and events of school sports. We want to get at least a general description and approximate measurement of our story here as we listen to the nationwide narrative about health and safety in school sports.
Early returns – that is, preliminary numbers for fall sports – are being presented to the MHSAA Representative Council today. A public release will follow before the end of the year. A more complete report – based on fall, winter and spring sports – will be provided after the conclusion of the 2015-16 school year. And in the future, year-to-year comparisons of the numbers will provide a more meaningful story.
The MHSAA is also gathering data from two pilot programs that are intended to increase attention on sideline concussion detection and recordkeeping, and also from the concussion care insurance the MHSAA has purchased for all participants in all MHSAA member junior high/middle schools and high schools beginning this school year.
Data from all three initiatives may help those who make the equipment and prepare the rules of play in the ongoing campaign to make our good school sports programs even better.
