Abstract: Since the mid 1980s, with the rapid development of international competitive sports, sports training sci-entific research paradigm which was established based on modern epistemology of linear science ever increasingly showed limitations which it cannot overcome when it was used to solve highly complicated sports training prob-lems, while nonlinear science provides a new perspective for us to understand real, complicated sports training problems. The theories and methods of non linear science have gradually caught the extensive attention of the aca-demic community of sports training, and started being applied to some areas of sports training. Nonlinear paradigm will be a new paradigm for studying the science of sports training in the 21st century.
Key words: science of sports training；nonlinear paradigm；sport research method
