Abstract: Physical Cultural Studies is an emerging research paradigm in sport sociology that has shifted towards a perspective of "subjectivity of body" in recent years. Influenced by the trends of the body sociology that emphasize "subjectivity", a number of pioneering researchers in the international sport sociology community have increasingly focused on physical activities and physical practices that are rooted in the study of the "body" as a "subjectivity-embodiment", and this has led to the formation of the academic school of Physical Cultural Studies. This paper systematically introduces the development of this school, including its main theoretical domains of the "subjectified body", "institutionalized body", "empirical body" and "politicalized body". It analyzes the contributions of this academic school to sport sociology, the debates it has sparked regarding the disciplinary positioning and knowledge systematization, and discusses the implications and prospects of this "new direction" for the study of sport sociology in China. The Physical Cultural Studies school emphasizes the "subjectivity" of the body in socio-cultural phenomena, representing a fundamental reflection and reconstruction of traditional sport sociology in terms of theory and methodology, which is beneficial for the development of an autonomous knowledge system in sport sociology in China.
