As quoted in the AP article:
"You'll all have to see. I'm not saying anything until we unveil it," Phelps said with a grin when asked how he's tweaked the stroke. "It's a significant change. You'll be able to tell exactly what I did as soon as I take my first stroke."
He's on tap to swim the 100- and 200-meter free and the 100 butterfly at the Charlotte UltraSwim in NC. Should be interesting to see.
Coach T:
I'd just like to mention that the body is controlled asymetrically by the brain. For example, the right arm/hand excels at close-to-body movements; that's where its spatial understanding lies. The left arm/hand excels at out-there movements more distant from the body. The difference between in-here and out-there neural control (and subsequent practical execution) is one reason why baseball hitters can't switch hit easily: they are trying to reverse the fields normally dominated by one or the other arm/hand.
I agree it's best not to teach loping as a technique to be implemented by young swimmers.
