Discussion on the Implementation Path of Multi-dimensional Linkage of Sports in Colleges and Universities

Multiple linkage is an important means of youth sports health promotion and plays an important role in the development of college sports. This paper constructs the sports multiple linkage model based on the theory of overlapping effect from 2 aspects of linkage goal and content structure, and establishes the evaluation index system of linkage effect, including 4 first-level indexes and 17 second-level indexes, such as linkage subject, linkage content, linkage implementation and linkage evaluation. Combining the subjective weights based on AHP method and the objective weights of information entropy method to combine and assign weights to the indicators, the improved TOPSIS comprehensive evaluation model is proposed, which emphasizes the importance of the linkage subject. Meanwhile, the regression analysis of multiple linkage influencing factors of college sports is conducted with X college as the research object. The results show that there is a significant positive correlation between the 13 variables of the linkage behavior factor variable and the linkage effect factor of the multiple linkage model with correlation coefficients ranging from 0.19 to 0.92 and P<0.05, and at the same time, these 13 variables are able to have an impact on the level of multiple linkage of college sports with 61.6% predictive effect. The study provides data for the comprehensive development of college sports and is of great practical significance in exploring the implementation path of multiple linkages in college sports.
