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.
Pivot Work
September 21, 2011
Consider the pivot move in basketball. The player receives the ball, plants his or her foot and spins 90 to 180 degrees. Without moving the pivot foot, the player turns from facing one direction to facing a different direction. And with that new perspective, the player either passes the ball to a cutting teammate or dribble drives toward the goal.
If these are pivotal times in school sports – and I believe they are – we must, if we are to make the most of these times, remember the skills that many of us worked on when we played basketball and still often admire as effective when we watch basketball. The pivot.
- One foot firmly planted. A foot that can’t be moved. Our base. Our fixed orientation.
- Then the spin that changes our field of vision from one direction to another.
- Then a sharp pass to a teammate, one who’s gotten a step on an opponent.
- Or, if no teammate is open to receive our assist, a determined drive of our own toward the goal.
If these are pivotal times, and if we are to be the “pivotal generation,” this is the drill: Fixed to our core beliefs, look around for new ideas and cutting edge partners to assist, and take it to the goal ourselves if we must.
