U.S. Olympic cycling manager Ed Burke presents practical cyclist-to-cyclist advice on how the heart, lungs, and muscles work and how this knowledge can help any rider get the most out of the sport. Burke, a leading expect on sports medicine, is a former competitive rider who turned his interest into a major field of study. A professor and the director of the Exercise Science Program at the University of Colorado, he is the author of fourteen books and writes columns for Winning Magazine, Mountain Biker, Muscular Development, Nutritional Science News, and NORBA News and answers fitness questions in Bicycling Magazine. Now he updates this popular book, first published in 1992, with the latest relevant discoveries in science and medicine and shows how they apply to everyday riding and racing.
