The meaning and basic elements of community sports As a kind of sports activity with regional characteristics, community sports refers to the sports activities carried out by members of society who live in a certain area and have the same lifestyle and sports consciousness, and consists of the following basic elements: (1) People who take sports as their profession or often engage in sports activities are the main body of community sports, and they are in the community. Therefore, the degree of community sports development is determined by the proportion of sports population to the total community population. (2) Community venues and facilities, that is, the necessary material conditions for people to carry out sports activities, play a protective and restrictive role in community sports activities and affect the behavior of social members participating in sports activities. Therefore, the degree of community development depends on the proportion of sports facilities per capita.

(4)*** The same sports consciousness, clothing community members must have similar sports consciousness and consciousness, which is the ideological basis for carrying out sports activities and plays a guiding role in community sports activities, directly affecting the behavior choices of social members participating in sports activities. 3. The classification and function of community sports can be divided into different types according to different standards. From the perspective of sports, it can be divided into community school sports and community competitive sports, which are interrelated and coordinated with each other. From the classification of communities, it can be divided into urban community sports, township community sports, rural community sports, community youth sports and community middle-aged and elderly sports. Because of the age difference, their activities have their own characteristics. Although the functions of community sports are different, they are consistent, mainly in three aspects (1): satisfying physical exercise and strengthening the system; (2) promoting people's healthy physique; (3) Promoting the construction of two civilizations in the community. 4. The relationship between community sports and national fitness It is a strategic task put forward in the Outline of National Fitness Program to carry out mass sports activities, promote national fitness and improve the health level of the Chinese nation. In the process of implementing this strategic task, community sports will play a long-term and important role. The consistency between community sports and the goal of national fitness is to improve people's awareness of sports participation, expand the number of people who often participate in sports activities, cultivate their awareness and habits of participating in sports activities, and achieve the goal of generally strengthening people's physique. As an important project of the country, the guidance of national fitness to the development of community sports has been concerned and supported by the government and the whole people. The development of community sports must be guided by the outline, incorporated into the overall planning of the outline, and carried out purposefully, planned and organized. The feasibility of community sports in implementing the national fitness plan is a long-term great project, and there must be practical methods to implement this great project. Developing community sports is an important way. As far as China is concerned, community sports is still very backward, but it already has the basic conditions for developing community sports, such as sports population, venues and facilities, sports organization and management system, etc. Therefore, it is not only necessary but also feasible to develop community sports. 5. Do a good job in community sports and strengthen community service. Community sports guidance centers, sports stations and consultation stations can be used as organizational forms of community sports to organize residents to carry out physical fitness activities. At the same time, establish a team of social sports instructors with organizational ability, technical level and enthusiastic service to the masses. Improve sports facilities in residential quarters, expand residents' sports venues, and guarantee residents' right to participate in sports. Carry out some sports activities with strong entertainment, low requirements for venues and facilities, simple sports methods and forms, and promote the construction of spiritual civilization with healthy and lively sports activities. To do well in community sports, we must rely on social forces to carry out various forms of sports activities. Community sports can give full play to its regional advantages, get rid of the traditional mode of planning by leaders and implementation by the masses, rely on units and enterprises with good sports conditions, improve the utilization rate of social resources, go deep into blocks and buildings, and carry out colorful sports activities for residents. They have complementary advantages in personnel, venue and activity form. Mobilize the masses to actively participate in physical fitness activities, promote the healthy development of the whole people, and make the national fitness activities enter thousands of households. To do well in community sports, we must attach importance to the role of sports associations. Family is the cell of society, but the determination and development of society cannot be separated from this factor. Sports activities are very important to people's health, and health is also the fundamental foundation of a family's happiness. Physical health is the foundation of creative behavior and the bond of family, which can promote family harmony and improve the quality of life. While doing mass sports activities well, social sports should also actively carry out some family-based sports and fitness programs, so as to truly make sports and fitness activities go deep into families and implement them to people, and make sports and fitness become the needs of families and the conscious actions of family members. In a word, developing community sports, promoting the healthy activities of urban residents, and actively promoting the in-depth development of township community sports and rural community sports are important components of promoting China's national fitness plan. With the continuous improvement of people's living standards, the rapid development of human science and technology, the continuous progress of material civilization and the continuous improvement of productivity, modern production methods and lifestyles bring wealth and leisure time to society and individuals, but also bring unfavorable factors and negative effects to people themselves. Physical health has become the most concerned issue in today's society. The Outline of the National Fitness Program attaches great importance to "actively developing community sports", so the development of community sports is becoming more and more important. Mobilizing all the people and the whole society to actively participate in and support mass sports activities and strive to improve the physique and health level of the whole nation is of great and far-reaching significance to the construction of spiritual civilization and material civilization in China, the prosperity of the nation and the health and happiness of future generations.
