Abstract: The authors gave an overview of representative research at home and abroad since the 20th century. Ac-cording to transdisciplinary theory evolution, quantitative research method application, etc, the authors collated such three debate focuses as “relationship identification, causal inference and dynamic tracking” as well as question re-sponse. Good physical health and excellent academic performance are positively correlative; physical health promo-tion has a significant causal effect on academic performance, and continues to produce a positive effect as time goes on. It is expected that the research will enrich physical index operability, explore the causal mechanism, and fully consider socio-demographic factors.
Key words: physical fitness；health promotion；academic performance；teenagers and children；casual inference
