Influence of the "Discipline Revolution" of American Physical Education on the Construction of the Knowledge System of Sport Science

"Discipline Revolution" originates from the criticism on the pragmatism of sports teachers, transferring sports science gradually from a technical to an academic discipline, thus to indicate the entry into an era of "post-modern sport science". For sport science as an "academic discipline", it is urgent to solve the three major problems: ①the boundary of sport academic knowledge system; ② the attribution of technical operation knowledge and professional knowledge in sports field; ③ the categories of knowledge that the sports majors have to command. Drawing lessons from the thought and experience of the "discipline revolution" of American physical education, the construction of the "physical education"theory in our country should be improved from the following three aspects: to change the research angle of "sport science"; to examine the boundary of sport knowledge; and to emphasize the construction of sport knowledge system.
