Abstract: At the new historical starting point, the ideological and political education construction in college physical education (PE) courses promotes the process of "grand ideological and political courses". Its theoretical characteristics of "pre-given advantages", "embodied participation" and "nature-language-behavior trinity" help renew the concept of improving ideological and political courses, broadening the vision and expanding the pattern, which is of great value in breaking through the bottlenecks in ideological and political education: the crux of rules and the imbalance of resource allocation, the subject-object dichotomy and role barriers of actors, and the ambiguity of the human-machine relationship in digital transformation. Embarking on a new journey in the new era, the ideological and political education in PE courses should: focus on the top-level design, push the improvement of ideological and political rules and the optimal allocation of resources; construct the subject-object relationship, attach importance to the exploration of ideological and political elements in PE courses under the guidance of educators' spirit, strengthen the building of international communication capacity, and empower the digital transformation of ideological and political education in PE courses through new quality productivity.
