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.
Channeling Change
May 7, 2014
In the ubiquitous discourse about global warming and rising seas, one school of thought follows this thread: (1) global warming’s fundamental cause is beyond human behavior; but (2) changing human behaviors could slow the rate of warming; and (3) these changed behaviors would improve the environment and the quality of existence for all the globe’s life forms and therefore should be promoted even if they cannot affect the ultimate warming of the planet.
Among those who admit to the inevitability that the planet will continue to warm regardless of humans’ best efforts are those who believe we should be planning for elevated sea levels now, not by working on ways to keep the rising waters out, but on innovative means of letting the water in.
With the Dutch, for example, among models, it is suggested that coastal communities begin today to build networks of canals that allow water to flow inland along planned routes that people can use and enjoy, and that the seawater be directed to places desperate for hydropower or where this seawater can be made free of unwanted species and fresh for human use and agriculture.
Rather than building walls to keep the water out, build canals to let water in to be cleansed and used for our betterment.
This caused me to wonder if this kind of thinking would help us in school sports to reframe discussion on problems that seem too large for us to solve. Like the negative influence of non-school sports on interscholastic athletics and rules that limit out-of-season coaching of students by school coaches.
Out-of-season coaching is one of the focus topics for the MHSAA during the second half of 2014, and this image in response to global warming is one of several we may use to reframe discussion before we attempt to rewrite the rules. Are there ways to channel negative situations toward positive results . . . without the threat of introducing invasive species?
