| With the promulgation of the "National Fitness Program",aerobics projects have continued to develop and gradually have a broad mass base,and the theoretical achievements of aerobics research have gradually enriched.In order to accurately grasp the current situation and development trend of aerobics research in China,the development law and research hotspots of aerobics scientific research literature in 16 core journals in China are explored,and the current situation of scientific research in the field of aerobics is analyzed,the implicit knowledge association in the papers is explored,the knowledge base of scientific research development is excavated and the future development trend is predicted.Through scientific metrology,the structure and evolutionary characteristics of knowledge networks in the field of aerobics in China are discussed from four levels:knowledge subject network,knowledge carrier network,knowledge ontology network and evolution trend of Chinese aerobics research;Using the method of citation analysis,it reveals the characteristics of mainstream scholars and cooperative groups in aerobics research in China;Using literature co-citation analysis,the source characteristics of journals that excavate the knowledge base and knowledge base of aerobics research in China are excavated;Using the co-word analysis method,the hot topics and knowledge structures of aerobics research in China are visually analyzed,the development law of aerobics research in China is summarized,the interrelationship between subject knowledge is revealed,and the potential research trend is discovered.The research results are as follows:（1）China’s aerobics research institutions are mostly concentrated in colleges and universities,and there is relatively more cooperation within high-yield institutions,and the scale of scientific research has not yet formed a large group.Most of the prolific authors are university teachers,and author collaboration is characterized by stratification.（2）The research themes of the ten highly cited classic literature on aerobics in China are mainly the research on the concept of aerobics,the evolution of aerobics competition rules,the current situation and countermeasures of aerobics teaching,the development trend of competitive aerobics and the expressiveness of athletes.The highly cited journals of aerobics research in China are mainly journals founded by sports colleges and universities that have transferred to professionalism.（3）Through sorting out the research hotspots,the knowledge structure of aerobics research in China is summarized as three research themes: competitive aerobics,aerobics teaching,and public aerobics.（4）Through evolutionary analysis,it is found that the orientation of research themes is mostly influenced by research frontier hotspots and related policies,and sports training（aerobics training）and humanistic social research（aerobics theory and social values）may become the cutting-edge trends of aerobics research in recent years.From the above findings,the following conclusions are drawn:（1）The distribution of the main body network of aerobics research in China has the characteristics of concentration and discrete coexistence.The node distribution in the network has the characteristics of concentration and discrete.From the perspective of institutional cooperation networks,there is relatively more cooperation within high-yield institutions,the cooperation between various institutions is not close,the scale of scientific research has not yet formed a large group,and the regional nature of institutional cooperation is obvious.From the perspective of the author cooperation network,the scale of cooperation is not large,generally 2-4 people,the cooperation between high-yield authors is relatively close,there is more cooperation between colleagues,teachers and students,and there are layered characteristics of author cooperation.（2）China’s aerobics research knowledge carrier network has internalized characteristics.Most of the highly cited core journals in the field of aerobics in China are sports and sports training,school sports magazines,and the self-citation rate within the discipline is high.Most of the knowledge base content of the highly cited literature in China’s aerobics research focuses on the teaching and training of aerobics,and the research content is highly concentrated.The absorption of high-quality content from other disciplines by aerobics research in China needs to be strengthened,the degree of interdisciplinary integration is low,and the internalization characteristics of the knowledge carrier network are obvious.（3）The knowledge ontology network of aerobics research in China has the characteristics of development and progression.The ontology network of aerobics research knowledge reflects the distribution of research hotspots,and the hot topics of aerobics research in China continue to develop and differentiate with the rules of aerobics competitions,school sports reform,and the promulgation of national sports policies,and with the progress of modern science and technology,the depth of research content is progressing layer by layer.（4）The evolution of knowledge networks in aerobics research in China has overlapping and related characteristics.The random probability of linking between nodes in the knowledge network of aerobics research in China is between 0 and 1,which is in line with the characteristics of complex networks.The content of aerobics research in China mainly revolves around the main axis of aerobics teaching,aerobics competition and training,and differentiates many relatively independent and interrelated research topics.The focus between the themes is relatively prominent,involving a wide range of features,and is still in the process of continuous differentiation and integration.There is a certain overlap and continuity between the focus and hot frontier content of aerobics research from different perspectives and at different times,and the evolution of three evolutionary modes as a whole follows horizontal evolution,vertical evolution and co-evolution. |
