In order to explore how to change the singularity of the existing public physical education teaching mode, this paper introduces Internet multimedia technology to analyze physical education. Firstly, the characteristics of Internet multimedia technology were analyzed to construct a fuzzy evaluation model based on Internet multimedia technology divided into index weights, primary fuzzy evaluation, and secondary fuzzy evaluation. Secondly, some teaching indicators were statistically categorized through the method of a statistical survey, and the results of the survey were calculated to eliminate indicators lower than 85%, and the evaluation system of public physical education mixed teaching indicators was constructed. Finally, it was concluded through the experiment that 52.11% of the experts think the application level of Internet multimedia technology in public physical education hybrid teaching is now advanced and in an acceptable state. There are 36.27% of experts think that the application level is now intermediate and needs to be reduced to an acceptable level according to the program regulations. 11.82% of the experts believe that the application level is now low, unacceptable, and needs to be rectified immediately. Thus, it is concluded that public physical education based on Internet technology can enrich the existing physical education model and increase the diversity of physical education models.
