College physical education is a part of school physical education and plays an important role in lifelong physical education. Physical education in colleges and universities bears the heavy responsibility of "health education and lifelong education" for college students. In recent years, tennis, as a healthy, elegant and fashionable sport, is increasingly loved by college students. The study of tennis and lifelong sports in colleges and universities plays an important role in the promotion and popularization of tennis. First, the relationship between tennis and lifelong physical education in colleges and universities. The idea of lifelong physical education comes from lifelong education, which is the sum of all kinds of physical education and training people have received in their lives. [1] The core of lifelong sports is to make sports run through people's life, make preschool sports, school sports and social sports closely linked, maintain the unity, integrity and coherence of sports and realize integration. School physical education, as an intermediate link of lifelong physical education, plays a bridge role, especially school physical education has a significant cornerstone function. Physical education in colleges and universities is a part of school physical education, which has the function of "laying the foundation". Through physical education teaching activities, extracurricular activities and competitions in colleges and universities, young students are urged to receive physical education, learn and master the basic knowledge, skills and scientific methods of physical exercise, so that they can get the best relaxation and adjustment in their intense study life and fully enjoy the vitality of youth in various physical education teaching activities. Second, the unique advantages of tennis in college physical education. Tennis was once called an aristocratic sport. With the rapid growth of China's economy, especially the tennis craze brought by China's outstanding achievements in some major competitions, tennis has also developed rapidly in China. From the psychological point of view, students' psychological demand for a certain sport determines their devotion to the sport, and good learning motivation is conducive to the formation of college students' lifelong sports thoughts. 1.

Playing tennis can exchange skills, enhance friendship and carry out social activities. On the court, it is easy for golfers to participate and gain trust. Players can not only communicate with each other to improve their skills, but also learn from each other in other aspects, learn from each other's strengths and improve their own quality.
