Abstract: The misuse of technology in sport functions as stimulants, which not only violates the legislative purpose of anti-doping rules, but hinders the fairness and justice of sports competitions, dispels the subjectivity of athletes, and endangers the long-term interests of specific sports. Under the existing regulatory system, the legal status of anti technology doping law has yet to be found in the higher-level laws domestically and abroad, leading to multiple legal problems. Therefore, China should rationally define the composition of technology doping, especially its causality with unfair advantages, and take actions from three perspectives, namely, legislative, judicial and enforcement: to promote World Anti-Doping Code to acknowledge the illegality of technical stimulants; to push the formation of a unified, coordinated and coherent judgment attitude of CAS; and to promote the formulation of more coercive regulatory measures and regulatory system of anti technology doping, thus to effectively safeguard the legitimate interests of sports.
