The birth of generative artificial intelligence technology brings important opportunities for the optimization of physical education gov-ernance system and the improvement of governance efficiency.By using the method of literature and logical analysis,this paper discusses the in-ternal logic and realistic dilemma of the modernization of physical education governance enabled by generative artificial intelligence,and puts forward the practical path.Internal logic:taking students as the center,improving the governance effect of physical education;promoting class-room innovation and enhancing the effectiveness of physical education governance;accelerating digital transformation and improving the effi-ciency of sports education governance.Realistic dilemma:potential risks of generative artificial intelligence technology,introduced into the field of sports education governance;the phenomenon of data silos is significant,which limits the efficacy of generative artificial intelligence technol-ogy;the physical education governance system is limited to the risks of generative artificial intelligence technology.Practice path:improving the governance system of physical ducation;strengthening the management level of physical education;establishing a governance framework for physical education.
