In the evening, a gas volleyball match is underway at the No.21 Middle School Gymnasium in Changchun City, Jilin Province. In the final game, the situation was sticky, with the two sides scoring alternately. At 14:13, Liu Tong's team temporarily took the lead, and one more point would win. The ball came and went, and Liu Tong made a powerful dunk in the back court, scoring, and ultimately winning the game. She and her companions cheered and hugged to celebrate. Air volleyball is a mass sports event that integrates sports, leisure, and entertainment, and is deeply loved by middle-aged and elderly groups. In Jilin Province, gas volleyball associations or clubs have been established in 36 counties and cities, and a number of competitions and activities have been carried out in an orderly manner. Air volleyball is light in weight and slow in descent, suitable for exercise for middle-aged and elderly people. Liu Tong, 56, was a member of the Jilin Province volleyball team and rarely played volleyball after retirement. A few years ago, her former teammate had an appointment to play volleyball together, and Liu Tong became passionate about the sport again. However, several times, her body felt a bit overwhelmed. At the suggestion of a friend, Liu Tong and his teammates began to practice gas volleyball and regain their sports happiness. At the beginning of practicing air volleyball, Liu Tong was not accustomed to it. "Compared to hard volleyball, air volleyball is light in weight and slow in descent." Through more communication, learning, and deliberation, Liu Tong gradually adapted to the playing method of air volleyball. Qian Yongmei, 53, is a professor at Jilin Architecture University. In 2015, when she first came into contact with gas volleyball, she fell in love with the sport. "I have always had a habit of exercising, and after exposure to gas volleyball, I have even aroused my interest in sports. I am particularly happy every time I play basketball, and I will continue to play after retirement," Qian Yongmei said. In 2017, the 13th National Games added mass competitions such as air volleyball, and Qian Yongmei participated as a member of the Jilin team. In 2021, Qian Yongmei and his teammates participated in the gas volleyball event of the 14th National Games again. "I didn't expect to be able to participate in the National Games when I was over 50 years old." "I once participated in mass competitions for the National Games on behalf of the Jilin team, and on behalf of the middle-aged women's air volleyball team in Jiutai District, Changchun City, I won the provincial sports championship. Not long ago, at the first community sports meeting in Jilin Province held in Tonghua City, my team, the Jilin Air Volleyball Association, won the championship again!" These experiences enriched Liu Tong's retirement life, "The biggest achievement is to feel the joy of sports and make friends with similar interests." Many air volleyball associations and clubs have been established, with more and more participants on the court. Middle-aged and elderly people and young people compete together without losing ground. On the stand, the audience watched the game enthusiastically and cheerfully. Why is gas volleyball popular among middle-aged and elderly groups? According to Tan Shiwen, executive vice chairman and head coach of Jilin Province Gas Volleyball Association, the weight of gas volleyball is about 100 grams lighter than hard volleyball, which is more suitable for middle-aged and elderly people to control; The requirements for sports venues are also simple. A badminton venue can be slightly adjusted to carry out air volleyball, reducing the threshold for public participation. Tan Shiwen, 67, was a professor of volleyball at Jilin Institute of Physical Education. After retirement, he devoted himself to the promotion of gas volleyball. "At the beginning, many people didn't know what gas volleyball was, especially middle-aged and elderly people. As soon as they heard of volleyball, they waved their hands and said that the exercise intensity was too strong and their bodies couldn't keep up." After several years of efforts, gas volleyball associations or associations were established in many places in Jilin Province
