Back in 1984, Hatfield asked several Navy riflemen to shoot at a target while he monitored their brain activity. He found that when the best shooters pulled the trigger, their left brain quieted and their right brain fired up. In all the inferior riflemen, left-brain activity remained fairly constant. They experienced little or no right-to-left brain transfer.
On the field, the left brain is like a D-back jamming you at the line of scrimmage. That’s the “thinking” side of the brain, the side in charge of motor skills. According to sports psychologist Trevor Moawad, athletes actually say anywhere from 60 to 800 things to themselves in a game, and it’s the left brain that does all the talking. Strahan has actually heard himself say things like “I feel sluggish” and “Are my feet under me?”
That self-talk takes up valuable time and slows the body. But when an athlete is calm and confident, the more creative right brain takes over, and the self-talk — and hesitation — subsides. Athletes call that being in The Zone, but really it’s just left-brain/ right-brain teamwork. “The Zone,” says psycho- physiologist Evan Brody, “is a thought-free state.” Remember when Michael Jordan scored 35 points in one half to open the ’92 Finals against Portland? After hitting his sixth three in 18 minutes, MJ turned to press row and shrugged as if to say, “Even I can’t explain this.” Right-brain transfer, Mike.
