Abstract: The “multi-competition system” makes the occurrence of high performance athletes, challenging the practicability of traditional training theories. In the mean time, rethinking whether the research frameworks, meth-ods and concept systems established by their research paradigms adapt to the development of the times also indi-cates a training theory research paradigm revolution. By using the methods of literature, history and logic, and com-plexity science, starting with analyzing high performance athlete training complexity, the authors systematically collated the “adaptability” of traditional training theories, and then put forward the research need of a complex re-search paradigm, so as to expand the frontier research vision of this theory. The authors concluded the followings: applying traditional training theories established by simple paradigms to high performance athletes participating in the “multi-competition system” exposed limitations; a complex research paradigm should be established for high performance athlete training theory research.
