Abstract: As a theory based on social, economic, environmental and technological systems, social ecosystem theory can analyze the dynamic impact of time on athletes ‘growth from this perspective, and then discuss the dynamic synergy mechanism for cultivating China aerobics world champions. By integrating event data and athletes ‘growth paths from 1995 to 2024, combined with time series analysis and case studies, the collaborative laws of athletes’ individual development, international event cycles and social ecosystems are revealed. The study found that the training of world champions follows the “five-stage chronological path” and the “dual-period collaborative model”, and its core driving force stems from the interaction of the micro system (training environment), the meso system (event cycle) and the macro system (policy support). The “social ecological time-series synergy model” constructed based on research results provides theoretical basis and practical paradigm for the cultivation of competitive sports talents.
