Under the backdrop of the in-depth advancement of the "Healthy China" strategy and the continuous deepening of the integration of physical education and school education

improving the physical health of primary and secondary school students has become a core issue in basic education. Currently

the traditional physical fitness testing and intervention models in China's primary and secondary schools have many pain points

such as rough data collection

one-sided evaluation

lagging intervention

and insufficient collaboration between schools and families

which are difficult to meet the personalized health development needs of teenagers. The smart sports platform

relying on digital technologies such as the Internet of Things

artificial intelligence

big data

and cloud computing

has built a full-cycle physical health management system of "precise detection - intelligent analysis - personalized intervention - dynamic tracking"

providing a new technical path to solve the problem of improving the physical fitness of primary and secondary school students. This paper

through literature review

case analysis

and logical analysis

defines the core connotations of the smart sports platform and precise physical health management for primary and secondary school students

analyzes the practical difficulties of traditional physical fitness testing and intervention

systematically expounds the core mechanisms and practical paths of the smart sports platform in empowering precise detection

precise analysis

and precise intervention

verifies the application effects through campus practice cases

and at the same time sorts out the technical

teaching staff

and data security issues existing in the current promotion and application of the platform

and puts forward targeted optimization strategies

aiming to provide theoretical references and practical references for the large-scale implementation of smart sports technology in the field of physical health management of primary and secondary school students and the long-term improvement of teenagers' physical health.
