Non-essential function of sports (the role of sports)
1. The political function of sports. First of all, it is reflected in winning glory for the country and improving its national prestige and international status. Large-scale international competitions have a direct impact on the honor and disgrace of the country. Many countries in the world have always regarded international sports competitions as an important stage to show their own systems and national consciousness. People often regard sports competition as a "ceremonial" war in a peaceful atmosphere of human society. It plays a unique role in maintaining world peace, promoting understanding among people of all countries, establishing normal norms of international relations and the self-regulation mechanism of human society. Because sports transcend language barriers and non-national characteristics, the Olympic Games has become an integral part of the world peace movement. In the international political arena, it inevitably becomes a diplomatic tool. Over the years, China insisted that People's Republic of China (PRC), as the sole legitimate representative of the China people, participate in the international Olympic Games, and made unremitting struggles to safeguard national sovereignty and oppose separatism. The Soviet Union, the United States and other countries boycotted each other in the two Olympic Games 1980 and 1984. China table tennis team opened the door to the establishment of diplomatic relations between China and the United States, and became a much-told story in the history of world sports. These are the embodiment of the political function of sports. Sports is also an effective means to strengthen national cohesion and promote domestic political integration. 1990 The torch relay held in China during the 11th Asian Games is a typical example.
2. The economic function of sports. It seems that sports can not produce direct economic benefits, but it can improve production efficiency and promote the development of social productive forces. Today, most factory directors and managers of people of insight regard it as an important link for employees to exercise, improve health and improve attendance. The philosophical formula "8-l is greater than 8" put forward by China and Tsinghua University illustrates this point.
The economic function of sports is also reflected in its media function. Nowadays, people's awareness of commodities is increasing day by day, and all kinds of sports competitions in the name of "Cup" are often marked by fierce sports competitions in front of the stage and advertising wars in the background. With the increasing demand for sports, sports industry and sports commodity economy have become a new industrial sector and commodity field. At present, in economically developed countries, the sports industry is expanding rapidly in both scale and scope, including sports tourism, sports performances, sports buildings and other sports operations. In particular, large-scale sports competitions across continents will not only bring huge economic benefits to entertainment, catering, transportation, tourism, hotel industry and sports equipment and accessories industry in a country or region, but also bring considerable economic benefits to TV, radio, souvenirs, sports lottery issuance, commodity patents and high ticket income in that country or region. In addition, large-scale sports competitions can also create considerable employment opportunities for people. During the 23rd Olympic Games held in the United States from 65438 to 0984, the influence of the American Economic Research Association on California was investigated. In a tangible and directly quantifiable range, the total income reached $3.29 billion. 1990 successfully held the 11th Asian Games in Beijing, China, which not only enhanced China's international influence and prestige politically, but also provided a rare opportunity to promote the capital construction, revitalize the socialist economy, promote the scientific development of some industries such as construction and biological testing, and even revitalize the economy of the entire Asia-Pacific region. All these show that the economic function of sports, whether direct or indirect, is enormous.
3. The cultural function of sports. As a social and cultural phenomenon, sports itself contains rich cultural connotations, and sports culture has a historical origin. Various ceremonial activities held by ancient people often express people's thoughts, spirits and concepts in the form of sports (such as the appearance of ancient Olympic Games). The cultural characteristics of sports are embodied in distinctive symbolism, rich artistry and rich connotation. For example, the five rings of the Olympic Games symbolize the unity of the five continents, and the flame symbolizes the light of civilization, indicating life, enthusiasm and vitality. The emblem and mascot of each session also have rich moral and symbolic significance. When people hold some large-scale activities and the opening and closing ceremonies of various cultural activities, sports performances are often essential. It can be seen that sports is not only a biological movement of human beings, but also a display of human spirit, intelligence and art. The rich sports human body culture not only actively transforms the anatomical structure and physiological functions of the human body, but also has great aesthetic enlightenment and edification for human labor itself. Magnificent sports buildings, wonderful and diverse sports equipment and facilities, and colorful sports equipment are not only the products of human labor, but also the crystallization of human material culture. As a cultural form, sports undoubtedly affects people's spirit, thoughts and consciousness as well as their organisms. The spirit of tenacious struggle, enterprising spirit, fair competition, unity and friendship, patriotism and internationalism in sports are highly reflected in people's spiritual field.
4. The scientific and technological function of sports. Science and technology are the primary productive forces, and the development of sports benefits from the progress of human social science, thus gradually forming a huge sports science system, which contains many components of human life science. The development of sports science and technology and the improvement of sports level benefit from the achievements of natural sciences such as human anatomy, sports medicine, sports health care, sports biomechanics and sports biochemistry. The behavior and spirit of sports have been recognized by the society, and only the demonstration of social sciences such as sports sociology, sports management, sports economics, sports statistics, sports psychology, sports history and sports behavior can flourish. Sports benefit from science and technology, which in turn provides a broader experimental field and market for the development of science and technology. The application of various new materials and electronic technologies in the field of sports makes sports equipment and facilities more scientific and advanced. So that competitive sports broke the prediction of "limit" again and again. At present, the sports circles in various countries have turned their attention to the development of information science, bio-genetic engineering, molecular biology, laser technology, biophysics and other high and new technologies, hoping that they can bring greater impetus to the development of human sports. Some people compare the Olympic Games to the embodiment of a country's comprehensive national strength. It is more like a testing ground of modern science and technology and a window of scientific and technological strength of various countries.
