Physical advantages
At the top of his career, Miguel Indurain had a physiology that was not only superior when compared to average people, but also when compared to his fellow athletes. His blood circulation had the ability to circulate 7 litres of blood around his body per minute,[1] compared to the average amount of 3-4 litres of an ordinary person and the 5-6 litres of his fellow riders. His Cardiac Output is 50L a minute, a fit amateur cyclist's is about 25L a minute. Also, Indurain's lung capacity was 8 litres, compared to an average of 6 litres. In addition, Indurain's resting pulse was as low as 28 BPM, compared to a normal human's 60-80 bpm , which meant his heart would be less strained in the tough mountain stages.[2] His VO2 max was 88 ml/kg/min; in comparison, Lance Armstrong's was 82 ml/kg/min and Greg LeMond's was 92.5 ml/kg/min.
