This paper discusses the dynamic mechanism and realistic dilemma of the deep integration of sports intangible cultural heritage and tourism, and puts forward the corresponding realization path. First of all, the dynamic mechanisms such as policy promotion and support, economic drive and market demand, social participation and community mobilization, technological innovation and digital transformation provide a strong guarantee for the tourism of traditional sports. However, the contradiction between protection and commercialization, lack of participation and social identity, insufficient resource allocation and infrastructure, and insufficient cultural identity and education promotion restrict its sustainable development. Therefore, the paper suggests that the deep integration of sports intangible cultural heritage and tourism should be promoted by strengthening policy support and system guarantee, innovating activity forms and experience modes, deepening education promotion and social recognition, and strengthening cross-border cooperation and resource integration. Through multi-party cooperation and innovative means, the attraction and social identity of traditional sports will be enhanced, and its development in the modern tourism market will be promoted, and finally a win-win situation of cultural inheritance and economic development will be realized.
