with the improvement of people's living standards and cultural quality, the concept of lifelong physical education has become the focus of attention. The main purpose of this paper is how to better combine lifelong physical education ideas with practical activities and improve the enthusiasm of college students. In this paper, questionnaire survey and data mining technology are used to investigate the students of a university in Jiangxi Province, and 924 valid questionnaires are collected. The results show that 41.02% of the students exercise two or three times a week; 41.77% of the students think that sports activities are average; 51.62% of the students' motivation to participate in sports activities is to lose weight. This shows that the college students' participation in sports activities is not high, their attitude is general, and their motivation is not strong enough. 343 and 317 students think that the main factors affecting their participation in sports activities are activity type, location and facilities. Therefore, colleges and universities should improve students' enthusiasm, carry out various forms of sports activities, and create a good sports atmosphere.
