In this paper, this paper proposes a research scheme on the correlation between students’ sports behavior and performance based on Apriori algorithm to better solve this problem. In this scheme, the influencing factors is accurately located through the frequent item set theory, so as to determine the division of indicators, and the Apriori algorithm is used to construct the scheme. Experimental results show that under certain evaluation criteria, the accuracy and speed of the scheme is significantly improved for different problems, and it has better performance. Therefore, the simulation scheme based on Apriori algorithm can better solve the limitations of the traditional grey correlation algorithm and improve the simulation accuracy and efficiency in the study of the correlation between sports behavior and performance of college students.
