Abstract: Descartes let the subject stand upright, made the body evolve into an object of ego – the body becomes the other of me, therefore affecting the formation of sports body view since modern times. Body objectification makes the body become an object of science, in accordance with the principle of science precision, repeatability and stability, the body is disenchanted unrestrictedly in front of science; in the mean time, body objectification intensifies the body’s tool nature. For different subject purposes, the body is processed and remodeled to the maximum extent, the objective body is hence regulated by social cultural power in the process of generation, ultimately developing into a bodily tool that not only meets social mainstream value expectation, but also can effectively exert body efficacy. Sport in the cultural world, usually undertakes a specific body mission, and embodies the construction will of society and country; while ra-tional spirit, scientific orientation and social custom are cultural construction forces that shape sport.
Key words: sports philosophy；cultural world；body construction
