A study on multimodal assessment and intervention strategies of the impact of college volleyball teaching on students’ physical and mental health

The purpose of this study is to explore the influence of volleyball teaching in colleges and universities on students’ physical and mental health, and to systematically analyze it by multi-modal evaluation method. 300 college students were randomly divided into experimental group and control group. The experimental group received personalized intervention based on multimodal evaluation system during 16 weeks of volleyball teaching, covering multi-dimensional monitoring and feedback of physiological, psychological and technical performance. Through heart rate, body fat rate, heart rate variability (HRV), GHQ-12 scale, technical score and self-efficacy, the students’ physical quality, mental health, technical proficiency and self-efficacy were comprehensively evaluated. The results show that the multimodal intervention strategy is effective in improving physical health and mental health, and the experimental group is superior to the control group in heart rate, body fat rate, vital capacity, HRV, GHQ-12 score, technical proficiency and self-efficacy. The real-time monitoring and feedback of multimodal assessment in teaching optimizes the intervention effect and provides a scientific basis for the optimization of physical education courses in colleges and universities.
