Sometimes, during my daily browsing of the Web for news and interesting angles on the sport science world, I get lucky and hit a home run.  I stumbled on this great May 2007 Wired article by Jennifer Kahn, Wayne Gretzky-Style 'Field Sense' May Be Teachable.  It ties together the people and themes of several of my recent posts, focusing on the concept of perception in sports.

Wayne Gretzky is often held up as the ultimate example of an athlete with average physical stature, who used his cognitive and perceptual skills to beat opponents. Joining Gretzky in the "brains over brawn" Hall of Fame would be pitcher Greg Maddux, NBA guard Steve Nash and quarterback Joe Montana.  They were all told as teenagers that they didn't have the size to succeed in college or the pros, but they countered this by becoming master students of the game, constantly searching for visual cues that would give them the advantage of a fraction of second or the element of surprise.

Its something that every coach and every athlete of every sport is searching for... the EDGE. That one training tip, equipment improvement, mental preparation or tactical insight that will tip the game towards them. The body of knowledge that exists today in each sport is assumed, with each competitor expected to at least be aware of the history, beliefs and traditions of their individual sport. But, if each team is starting with the same set of information then the team that takes the next step by applying new research and ideas will capture the edge.

To me, that is what sport science is all about. The goal is to improve sports performance by imagining, analyzing, experimenting, testing, documenting and training new methods to coaches and athletes.

Athletes, both professional and amateur, as well as the general public are convinced that human growth hormone (HGH), Erythropoietin (EPO) and anabolic-androgenic steroids (AAS) are all artificial and controversial paths to improved performance in sports.  The recent headlines that have included Barry Bonds, Marion Jones, Floyd Landis, Dwayne Chambers, Jose Canseco, Jason Giambi, Roger Clemens and many lesser known names (see the amazingly long list of doping cases in sport) have referred to these three substances interchangeably leaving the public confused about who took what from whom. 

With so many athletes willing to gamble with their futures, they must be confident that they will see significant short-term results.  So, is it worth the risk?  Two very interesting recent studies provide some answers on at least one of the substances, HGH.

Here are some quotes we have all heard (or said ourselves) on the golf course or at the ball diamond. 
On a good day:
"It was like putting into the Grand Canyon"
"The baseball looked like a beach ball up there today"

On a bad day:
"The hole was as small as a thimble"
"I don't know, it looked like he was throwing marbles"

The baseball and the golf hole are the same size every day, so are these comments meaningless or do we really perceive these objects differently depending on the day's performance?  And, does our performance influence our perception or does our perception help our performance?

Visit any youth soccer field, baseball diamond, basketball court or football field and you will likely see them:  parents behaving badly.  Take a look at this Good Morning America report on "sideline rage".  Sometimes, these are the extremes, but at most games, you can find at least one adult making comments at the referee, shouting at their child, or having a verbal exchange with another parent.  Thankfully, these parents represent only a small percentage of those attending the game.  Does that mean the others don't become upset at something during the game?  Usually not, as there are lots of opportunities to dispute a bad call or observe rough play or react to one of these loud parents.

The difference is in our basic personality psyche, according to Jay Goldstein, a kinesiology doctoral student at the University of Maryland School of Public Health.  His thesis, recently published in the Journal of Applied Social Psychology (see reference below), hypothesized that a parent with "control-oriented" personality would react to events at a game more than a parent with an "autonomy-oriented" personality.
