Most athletes are more likely to have AD(H)D than AS. However, I do think people with AS may excel at sports such as middle and long-distance running, sports that people can train for by themselves.
I think Roger Bannister had strong AS traits, mainly the positive ones. He was smart, charted his own course (which put him out of favor with the British press) and excelled in a highly systematizing profession, medicine. He approached his running with a scientific approach an NT never would have used.
Paavo Nurmi of Finland and Jules Ladoumege of France also likely had AS traits, but they were not nearly as successful in all aspects of their lives as Bannister. Nurmi's running cost him his marriage after only a year, and he died an embittered old man. Ladoumege lived alone in a small apartment with only a cat and a dog for company, having been suspended for taking excessive expense money. (Nurmi had been as well). Bannister, on the other hand, went on to a distinguished career in neurology and has been married for over 50 years.
Bannister is an example of a success story, and an embodiment of his credo that nothing is impossible. When I feel I can't do something, I think of his example.
