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.
What ever Phelps technique change is, you can be sure Bob Bowman is the architect of it. My guess is Bob studied Eamon & Alain's technique (the only 2 swimmers who swam faster in the 100 free than Phelps.) Bowman asked "What can Michael do to swim faster?"
He came up with some ideas, they've tested it in workouts, decided it's a good thing, worked to make it a habit and now Phelps is going to test it in a race.
Probably straight arm recovery
Maybe dolphin kick instead of flutter while swimming freestyle.
On a different note, since Phelps is no longer swimming the 400 IM. Bowman's probably determined Phelps needs to be stronger to swim faster 100's.
Especially since Rafael Munoz Perez proved at the French Long Course National Championships that his 50 Mariposa speed wasn't a fluke.
