In today’s rapidly developing technology, user interfaces are gradually evolving into a multidisciplinary and integrated design science. In the information age, the user interface design of digital products is a key factor determining the user experience of digital products. The current design of sports training interactive interfaces is too complex, and users may need to spend a long time adapting and understanding the operation of the interface, which limits its convenience in use. If a more accurate, easy-to-use, and intuitive interface design can be provided, athletes and sports enthusiasts can monitor their physical health in real-time on the mobile end, and can view training data at any time to effectively improve training effectiveness. This article analyzed the sports training interaction interface under human intelligent health monitoring technology, and analyzed the development process of human intelligent health monitoring technology and introduced the application of health monitoring technology in smart medicine through real-time case analysis. This article also randomly selected a sports training activity center and learned about the athletes’ needs for sports training interaction interface design through interviews. Based on questionnaire data, data statistics were conducted to retain improvement suggestions. In the preparation work for the design of the sports training interactive interface, the needs of the personnel of the sports activity center for the interface design were analyzed, and the design of the sports training interactive interface for human intelligent health monitoring technology was explored. After conducting a satisfaction survey on interactive gestures, a total of 104 people were satisfied with the interface interaction gesture design, accounting for 86.7% of the total number. It can be seen that satisfaction has increased after the improvement. This article believed that in the design of sports training interactive interfaces based on human intelligent health monitoring technology, emphasis should be placed on considering the needs of target users and adopting appropriate interface structures to support applications.
