Teenagers are the future of our country, and their physical health has a great impact on the economic and social development of our country. In view of this, this study applied questionnaire survey, analytic hierarchy and situation analysis to construct the evaluation index system and hierarchical structure model of youth physical health promotion path, and used empirical analysis to analyze and deal with the key factors in the index system. The results show that the coordinates are (0.648, 0.648, 0.648, 654) located in the first quadrant, which indicates that the external opportunities and internal advantages have a high degree of matching; the effect of youth physical health management under the government mechanism is poor, but youth physical health management under the market mechanism needs to be established. The internal advantages of youth physical health management are relatively large, and the public management service market has great potential, and the market-oriented health construction. It is hoped that this study can provide certain reference for the improvement of Chinese teenagers' physical health.
