Abstract: As a symbol of the post-human era, "Cyborg" has a great impact on the existential value of sportsmanship. Firstly, it breaks the boundary of "body" and makes the definition of "body" ambiguous. Secondly, it subverts the traditional concept of human nature and challenges the unique will of life. A series of problems brought by the above two aspects are very clear before the two important dimensions of sportsmanship -- sports justice and sports aesthetics. For example, the standard of sports identity justice needs to be redefined, the demarcation between sports and technology becomes more difficult, and sports aesthetics encounters deconstruction. The subversive dilemma of sportsmanship in the post-human era makes us reinterpretation the subject of life and the essence of human nature.

Key words: Cyborg, sportsmanship, body conception, post human
