Optimization Strategies of University Physical Education Course Evaluation System Based on Exercise Biomechanics

Abstract

This paper firstly constructs the structure of human lower limb motor system and the physiological structure and mechanics model of knee joint, and then studies the application of sports biomechanics in physical education course evaluation, which includes the construction and calculation of biokinetic indexes and bio kinematic indexes, as well as the feedback mechanism and dynamic adjustment strategy of the evaluation system. Finally, the evaluation results and analysis of college physical education courses are given, through the comparison of kinematic indexes of different fatigue levels in physical education and the comparative analysis of the effect of physical education specialization. The results show that there is a statistical difference in the knee extension moment at the moment of initial touchdown at different fatigue levels in college physical education (p=0.005). The knee extension moments at moderate fatigue (p=0.033) and after severe fatigue (p=0.013) were significantly greater than those at the no fatigue stage. The research results of this paper provide new ideas and methods for the evaluation of physical education courses in colleges and universities, which are important for promoting the development of physical education courses and improving teaching quality.
