Hmmm. That sounds like an attempt to try and fit the square peg of sport into the round hole of art. Art to me is a deliberately unpragmatic attempt to make sense of human existence. Sport, on the other hand, seems to me to be society's means of sublimating the natural competitiveness, aggression and athleticism of young men into a socially-acceptable form that also happens to be an enjoyable spectacle.
I think there is a definite crossover area. Consider the footballer who has trained his body to achieve the kind of balletic grace and control exhibited by Cruyff, Henry or Messi - this degree of exertion surely points to an individual seeking the truth of the human condition, much like, for example, the ballerina?
OK, but the footballer doesn't do this with the intention of looking good or making any point about anything. He does it with the narrow goal of winning a football match. Besides, in ballet, the dancers are just a tool - they're not artists in their own right. The 'art' lies in the writing of the music and the choreography. The dancing is just the technical physical expression of the art.
