In the global context of the new coronavirus pneumonia epidemic, its sustainability and extensive influence have led to unprecedented changes in the field of education. In the post-epidemic era, the normalized development of online teaching mode of physical education in colleges and universities not only challenges the traditional physical education teaching mode, but also profoundly tests the innovation and adaptability of physical education. In this transformation, the rapid rise of large-scale sports online teaching not only highlights the emergency response ability and importance of online physical education, but also greatly promotes the innovation of physical education teaching mode. As the core promoter, colleges and universities need to actively respond, not only to build an efficient and interactive physical education teaching environment at the technical level, but also to achieve a fundamental change in the concept, emphasizing the comprehensiveness and depth of physical education. Specifically, colleges and universities should go beyond the traditional goal of enhancing physical fitness and tempering will, and integrate moral education elements and curriculum ideological and political content through online platforms, aiming to cultivate students’ moral sentiment, social responsibility and humanistic quality. Therefore, we should integrate core values such as sports spirit, teamwork and fair competition into online curriculum design, promote students’ moral-oriented personality shaping and comprehensive quality improvement, and ensure that physical education continues to play its unique role and value of talent cultivation in the era of information-based teaching.
