Design of a computer-assisted physical education teaching platform based on the human-ground impact force dynamic model

The auxiliary teaching platform of physical education is becoming more and more important in college physical education, and it has become an ideal tool to promote the interaction between teachers and students and improve the teaching effect. Compared with the traditional physical education teaching mode, the platform has stronger interaction, efficient information sharing function and rich and varied multimedia display. However, there are still some shortcomings in the application of biomechanics in the online sports teaching platform. In this study, a computer-aided physical education teaching platform based on the dynamic model of human body-ground impact force is proposed. The study aims at analyzing the mechanical characteristics of human body in contact with the ground during exercise from the perspective of biomechanics, and helping teachers and students to choose sports equipment more accurately according to different course contents and biomechanical needs. By introducing the biomechanical model, the platform can simulate and analyze the key biomechanical data such as impact force, change of center of gravity, joint stress and so on, and provide quantitative feedback for students to optimize the effect of sports training. At the same time, the platform also integrates a variety of functional modules, such as sports resource information module and real-time sports evaluation module. It greatly enriches students’ learning resources, prolongs the time and space of self-directed learning, promotes the transformation of learning methods, and improves students’ autonomy, learning enthusiasm and sports performance. With the help of this platform, students can access rich learning resources including high-quality biomechanical analysis videos, interactive sports simulation, detailed theoretical explanation and real-time online evaluation system to comprehensively improve their sports literacy and sports performance.
