From 1992 to 1999, the year of his first Tour de France win, Armstrong was able to increase his muscle efficiency by 8 percent through hard and dedicated training. Ed Coyle (director of the Human Performance Laboratory at the University of Texas at Austin) says Armstrong is the only human who has been shown to change his muscle efficiency.
However, surviving cancer almost certainly made Armstrong a stronger athlete mentally. Sports scientists agree that Armstrong is one of the most disciplined and focused athletes in the world.
