Research On The Symbiosis Mechanism Of The National Fitness

National fitness, as an important measure on the road of Chinese Sports development, is the key concerned areas in the social development. Thinking for the national fitness development has become an inevitable topic since a new" National Fitness Program (2011-2015)" was issued and implemented. Based on the related researches, it can be summarized and discovered that the symbiotic relationship between the national fitness and other social elements has been realized by majorities of scholars and this phenomenon has aroused public awareness. Using this symbiotic association to promote the development of nationwide fitness is no doubt the direction for the national fitness cause development.The symbiosis theory in biology is to provide a theoretical basis for this symbiotic relationship. Based on the symbiosis theory, it is found that Symbiosis theory has been applied to interdisciplinary development and it has a positive effect for the further development of applied subjects. Case analyses, combinations of the development of nationwide fitness and symbiosis theory and summaries of national fitness symbiosis mechanism play significant roles in the national fitness development.This paper uses literature date method, questionnaire survey method, field survey method, interview method and other scientific methods to research and analyze three specific cases, namely, the project of public bicycle in Tongliang, the rural sports association of elder persons in Fuling, the hiking trails of Chongqing. The main contents for the research are as follows:The case of the project of public bicycle in Tongliang:Through the case investigation and research, the understanding the project origin, the implementation of objective, organization and management, source of funds and using ways, it is explored that the project has the function of public transport, city construction, national fitness and so on. They are formed into a symbiosis. By using the symbiosis theory, this thesis analyzes the symbiosis unit of which are composed by the project of public bicycle, public transport, city construction, national fitness composition. And the symbiosis environment of the project is constituted by the economic level, environment and social development level and policy orientation of Tongliang City;The case of the rural sports association of older persons in Fuling:Through the case investigation and research, the present situation of the rural sports association of older persons in Fuling has been initially recognized. And it is also found out that the problem of aging society has been solved. It takes the physical exercise into the rural life, drives young people to exercise, and provides a movable platform for the left-behind children to join the physical exercise, which forms a symbiosis construct. National fitness, the problem of aging society, the problem of left-behind children and farming problem together compose a symbiosis unit. Economic level, policy orientation and cultural orientation in Fuling City provide the symbiosis environment for the symbiosis system;The case of the hiking trails of Chongqing:Through the case investigation and research for the present situation of the hiking trails of Chongqing, it is detected that the hiking trail project does not only present distinct sports characteristics, but has the function of traffic, tourism and leisure, cultural heritage and communication. National fitness, city traffic, city tourism, city culture construction and man’s own development compose the symbiosis unit of it. Economic level, cultural heritage, geographical conditions and policy orientation of Chongqing City influence the symbiosis environment of the symbiosis development system;Based on the case analysis and study on the symbiosis theory, the national fitness symbiosis mechanism is constructed including induction mechanism, dynamic mechanism, and restriction mechanism. The induction mechanism includes sport environment induction inside and outside the sport field. The dynamic mechanism mainly refers to the national fitness and the symbiosis unit energy exchange degree. The restriction mechanism originates from sport environment induction inside and outside the sport field as well. In the all mechanism, induction mechanism, dynamic mechanism and restriction mechanism restrict and interact with each other. From the development direction, the induction mechanism needs increasing, the dynamic mechanism needs progressive enhancing, and the restriction mechanism needs weakening. Only like this, the national fitness symbiosis mechanism can get sustainable and long-term development.
