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.

Patience

January 20, 2015

I found it amazing that an important "test" match in cricket last month between India and Australia was scheduled for three days but could last five days, or might end after two. This flexible scheduling is just part of the game.

On one day of that match, Australia was able to bat all morning, declare a lunch break, and then keep batting most of the afternoon before India ever had an opportunity to go on offense. When they finally did, India was already behind 400 and something to zero.

It was equally intriguing to watch the fastest two of the 117 yachts entered in the 70th Sydney to Hobart Yacht Race finish the more than 628-nautical mile course within 48 minutes of each other, but 11 hours before the third place yacht. And, two days before the last of the 103 finishers. 

I decided that Australian sports fans must have a different definition of drama, a lot more patience for events of long duration, and much more tolerance for events of indefinite length than we do in the USA. Perhaps it is in the DNA of Australians to be patient ... for they are certainly among the most polite populations I've encountered.

Perhaps all of this is inherent in the character of a country that is almost as large as the USA’s first 48 states but has only seven percent of the USA’s population. In fact, China's population increases each year by more people than the total population of Australia ... which may have something to do with 36 people being killed during a human stampede in Shanghai this past New Year’s Eve.
