Abstract: By comprehensively using the methods of literature review, logic, philosophy, and complexity science, this present paper expounds the constraints of Chinese sports training theory as a result of adhering to the "constitutive law" methodology, clarifies the pathways to overcome the bottleneck in Chinese training theory methodology, and puts forward the proposition of innovating and constructing Chinese training theory for the new era. The research suggests that the primary form of Chinese sports training theory is the textbook "Sports Training", which inherits the main ideas from Matveyev's "Principles of Sports Training", establishes the Chinese training theory system and the theoretical model of the structure of excellent athletes' competitive abilities, and remains well aligned with the general systematic theory and methodology. In order to transcend the constraints of the "constitutive law" methodology, it is imperative to center focus on contemporary training issues and establish a unified perspective for multiple research paradigms. This entails emphasizing research on "upward causality" and developing methods for explaining the "dual causal chain" theory, reshaping the theoretical foundation of training theory research from focusing on "simplicity" to embracing "complexity"; advocating for an "integrated methodology" and formulating principles of research methodology for Chinese training theory. In the new era, the innovation and construction of Chinese sports training theory should primarily focus on top-level design. This involves courageously addressing scientific issues within training theory, establishing a solid foundation through forward-looking basic research, and unlocking theoretical innovations by deciphering "component structures" and leveraging data mining techniques.
