Online education has gradually become familiar to the public in the information age, and it has become the norm to carry out online lectures, conferences, and training, but due to the special nature of sports, online sports have not been a hot topic with the participation of the public. With the state's designation of NCP as a "Class B", the public's life gradually resumed normalization, and the online sports boom gradually receded. The current situation and teaching dilemmas of online physical education (OPE) have been studied in this study to explore the constraints encountered in its current practice, to study its common problems, and to provide countermeasures for OPE in the post-epidemic era. This will enable OPE to better integrate the characteristics of the Internet and lay the foundation for the formation of an online teaching method with physical education characteristics. To sort out the constraints of online sports development in the post-epidemic era and explore countermeasures for online teaching, so as to provide a boost for the future development of online sports teaching. The arrival of the new crown epidemic has made online sports a home fitness program for the general public, and this rare practical approach provides valuable experience for the development of online sports. With the theme of online teaching development, this study analyzes the constraints on online sports development and proposes targeted countermeasures through literature, interviews, and logical analysis methods. In the post-epidemic period, OPE is constrained by both endogenous factors (students' individual needs, lack of necessary supervision, and untimely communication) and exogenous factors (instructional design of online courses, quality teaching resources, and environmental and peer factors). By 1) improving the way to enhance students' participation in online sports, 2) establishing a diversified evaluation and supervision mechanism, 3) determining the role transformation and role of online sports courses, and 4) strengthen-How to cite this paper: Yu, J.
