If you're an athlete who leans toward strenuous workouts, whether you pound the pavement or fly down black diamond ski slopes, it is time to tweak your recovery, sports nutritionists say. Studies show that carbohydrates combined with a little protein creates a better muscle refueling and building response, and it reduces cortisol, a hormone that breaks down muscle. John Ivy, a kinesiologist at the University of Texas, has been one of the leading scientists advancing ideas about protein. He invented a sports drink used by Michael Phelps and his teammates on the swim team at the Beijing Olympics that's designed to reduce soreness and promote recovery when consumed soon after racing or working out.
