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.
The Problem with Exceptions
November 22, 2011
Picking up where my last blog left off, this posting presents two more of six lessons that experience has taught me during my enriching years with the MHSAA.
Lesson No. 2: Beware of bad precedent.
An exception today that doesn’t seem to matter much is almost certain to be recalled and used against you tomorrow when it really does matter. People have poor memories for most things, but they have long memories for exceptional things, like making an exception to a rule.
A corollary to this lesson is that “no good deed goes unpunished.”
Lesson No. 2 is closely related to Lesson No. 3: The path of least resistance usually is not.
Making an exception for a squeaky wheel will likely lead to more noise, not less.
One corollary to this lesson is that there will be more fallout when people believe you have ignored rules than when people believe you have been heartless in applying the rules as stated.
A second corollary to this is that following the rules is the safest harbor during stormy seas.
