Now I Know What Makes Lance Armstrong Great
Lance's heart is 30% larger than a typical person. His resting heart-rate is 32. He burns up to 10,000 calories a day during races, but manages to maintain his body weight within 3kg ALL YEAR. His body fat, in race trim, is 4-5% . His lungs process over 50% more oxygen than the average person: "Amstrong?s lungs can perform at twice the capacity of the average healthy man. Technically speaking, Armstrong's lungs use 85 milliliters of oxygen per kilogram of body weight during exercise, compared with 40 for other men." (MSNBC)
Damn..
