Overengineering
December 4, 2012
“Overengineering” is anathema to most product manufacturers. Generally, manufacturers desire to put no more time and money into a product than is necessary. They decide upon a reasonable lifespan for a product, and then they use materials and parts that, with rare exception, have been proven to last that long. They do not care to produce a product that lasts longer than the consumer desires; they do not want to invest resources where they won’t see a return.
An exception to this general rule is invoked by those manufacturing products which, if they break, will kill or maim people. Airplanes are the classic example: they’re built with multiple redundancies and with materials and parts that have been tested to last much longer than necessary. The potential for catastrophic loss of life demands this. They will use a part that’s tested to last 20 years, and replace it after ten years just to be safe.
I suspect that some observers of the MHSAA’s recent campaign to increase sports safety training for coaches and modify playing rules that may endanger participants are critical that we’re asking too much, that we’re doing more than is necessary. But frankly, that’s exactly what we intend. When it comes to participant safety, overengineering of policies and procedures ought to be our goal.
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.
