Since the reform and opening up, China’s national living standards have gradually improved, but the current physical health level of college students has not increased with the improvement of living standards. The physical health of college students — as high-quality talents of the country — is related to the future of the country and the nation,. In order to explore the influencing factors of college students’ physical health, the analytic hierarchy process (AHP) was used to evaluate the factors affecting students’ physical health. This study analyzes the index of students’ physical health through the method of literature, then revises the evaluation index through expert analysis and analytic hierarchy process, and verifies it through examples. The results show that the final score of the school students’ physical health is 81.55, of which the school factor has the greatest impact on the students’ physical health, and the school factor score is far from the expected score. We can promote the development of students’ physical exercise and improve the level of students’ physical health through the improvement of school sports management. This study provides reference for the healthy development of public sports students in China.
