Abstract: In 1992, China's reform and opening up entered a new stage, which provided a new opportunity for school physical education research. Based on the 2196 articles on school physical education in the CNKI core journal database and the masters' and doctoral thesis database from 1992 to 2019, this present paper analyzed the research content and dynamic evolution of school physical education in China by means of literature review and knowledge graph. The research shows that (1) the research on school physical education has shifted from a macro perspective to a micro perspective, and has gradually expanded in both breadth and depth; (2) there is a clear tendency towards the application of Marx's principle of universal connection; (3) the historical background and policy orientation in school physical education research are becoming more and more obvious, while the research needs to be further innovated in both perspectives and methods, and to be strengthened in both breadth and depth.
