College physical education teaching is all undertaken by various college physical education teaching departments. According to China’s education guidance outline, every college student needs to participate in physical education courses, but the number of physical education teachers in various colleges is generally small. Even if only grade one and grade two students offer physical education courses, the number is already quite large. In addition, there are huge individual differences among students, and the weekly physical education curriculum can no longer meet the needs of students to obtain more fitness knowledge and cultivate the awareness of lifelong sports. A large number of studies have shown that scientific and reasonable physical exercise can promote human health and improve the quality of life, and it is very important to formulate reasonable exercise prescriptions according to personal physical conditions to improve physical health and avoid physical injury. Therefore, this paper studies the construction of student physical health diagnosis and sports prescription network service platform. As a professional sports medicine service platform, the research team of this project has studied it for more than ten years. The results of data analysis show that there are many problems in the current physical health diagnosis and prescription network platform, and the number of patients is too small; The diagnosis result is not reliable enough; There is no common language between doctors and nurses; The diagnostic results cannot be used for prescription drugs or equipment.
