Research on the Construction and Campus Promotion of Prevention-Oriented Intervention Model for Physical Fitness Rehabilitation of College Students—Based on the Perspective of Improving Physical Health

The continuous decline in the physical health of university students has become an important public health issue, requiring preventive intervention before health risks develop into stable physical decline. Based on a prevention-oriented approach, this study constructs a systematic physical fitness rehabilitation intervention model for university students and verifies its effectiveness through empirical research. Using stratified random sampling, 800 students from a comprehensive university who failed the physical fitness test are selected as research subjects. A 16-week multidimensional intervention experiment is conducted to evaluate the effects of the model on physical fitness indicators, healthy behavior formation, and physical fitness test pass rate. Results show that after intervention, students’ vital capacity index increases by 12.3%, sit-and-reach performance improves by 18.7%, and the physical fitness test pass rate rises from 61.5% at baseline to 84.2%. Based on the empirical results, the study proposes a four-in-one campus promotion mechanism of “screening-intervention-follow-up-promotion,” providing an operable path for improving physical health in universities.
