With the deepening of the process of building a strong sports country, universities are increasingly emphasizing the important role of physical education learning interest in teaching. This article summarizes the current state and factors that affect college students’ interest in physical education learning, both domestically and internationally. Through the Individual Interest Scale for Physical Education Learning, the Situational Interest Scale for Physical Education Learning, and the Physical Education Learning Environmental Factors Questionnaire, a total of 450 undergraduate students nationwide were surveyed to exam the features of university students’ enthusiasm for physical training and propose suggestions on how to enhance college students’ learning interest and promote comprehensive physical and mental health development.
