Dina,
Brad picked up this book at a yardsale in NH for 50 cents. A good deal.
Here is a bit more, that I like:
?Running To The Top? Derek Clayton
Nature or Determination
Clayton was tested by Dr. David Costill at Ball State in 1970. Respiratory function tests were nothing unusual for a distance runner. Resting pulse rate of 35 BPM with a maximum rate 188BPM.
Previous research by Costill had shown a direct relationship between maximal ability of a runner and his or her distance running performance. Most of the distance runners Costill had tested had aerobic capacities ranging from 69-76 milliliters of oxygen consumed per minute per kilogram of body weight. Prefontaine VO2 max was 84.4, Shorter 71.3, Kardong 77.4.
Although their VO2 max was higher Clayton had the ability to utilize 80-85 percent of his maximum during a race. Most runners cannot do this.
Clayton?s max VO2 was 69.7. Therefore his running success cannot be explained totally in terms of circulatory or respiratory superiority. Costill was amazed, however at the speeds Clayton could tolerate with great ease. He was able to run an 8:32 two-mile despite being hampered by wearing the respiratory apparatus.
How much is nature and how much is determination? You have to be determined to find out.
?It is what a runner thinks he or she can do that creates success. Limits exist only on machines that test physiology rather than psychology.?
