| With the rapid development of knowledge economy era,continuous innovation is an important way to ensure the sustainable development of the subject field,and knowledge flow is a key factor to promote knowledge innovation.In order to accurately grasp the characteristics of the knowledge flow in the field of aerobics in China,this paper adopts the methods of bibliometrics and social network analysis to analyze the aerobics research literature,reference literature and citation literature collected in Chinese core sports journals.From the distribution of original literature,highly productive authors and institutions,the structural characteristics of research themes and authors absorbed and outflow,citation types,research hotspots,interdisciplinary and other aspects,this paper sorts out the characteristics and rules of the knowledge structure and knowledge flow process of this field respectively,so as to provide reference value for the enrichment and innovation of scientific research in the field of aerobics.It lays a good foundation for the optimization of its own knowledge structure and the future professional construction and discipline development.The results show that:Research results:(1)The knowledge carrier of scientific research citation of aerobics in China has gone through three stages: germination,rapid development and decline.The prolific authors of scientific research on aerobics mainly come from sports colleges and universities.From the perspective of research direction,most of them are experts and scholars in the field of their own disciplines,and few of them are interdisciplinary scholars;From the perspective of co authorship,the majority are in the form of solo works.The research institutions are mainly sports colleges and normal universities.The journal of Beijing Sport University is the first publication journal.The research topics mainly include competitive aerobics and aerobics teaching.(2)The annual distribution of the absorption and outflow of scientific research citation knowledge of aerobics in China shows a downward trend after the number increases to the peak;The time span of knowledge absorption literature is 71 years,and the time span of knowledge outflow literature is 30 years.The main sources of absorption are journals and books,and the largest proportion of knowledge outflow is degree papers and journals.Over time,the co-occurrence network density of both journals has shown a significant increase followed by a rapid decline in recent years.The topics of knowledge absorption focus on the characteristics and development of aerobics,school physical education,technical movements and rules of competitive aerobics,physical exercise to promote mental health,etc.The topics of knowledge outflow include the effect of boxing movement,the development of club courses,the influencing factors of expressive force,artistic arrangement,dynamic analysis and so on.There is certain overlap between the two in terms of journals,authors and research topics,but the research topics of knowledge outflow have the characteristics of wide range and deep level,which reflects that the aerobics field is closely related and has its own characteristics in terms of knowledge absorption and outflow.There are a total of 24 categories of knowledge absorption disciplines and 27 categories of knowledge outflow disciplines,with physical education as the main subject of absorption or outflow.Research conclusions:(1)The annual distribution of knowledge carriers,absorption,and outflow in the citation of aerobics research in China shows a trend from rapid development to gradual decline,showing a strong periodicity.Due to the fact that knowledge is absorbed and combined into new knowledge before flowing out,higher demands are placed on scientific research in the field of aerobics,and breakthroughs are urgently needed to achieve innovative scientific research and development.(2)In the study of knowledge carriers in aerobics,the number of independent papers is close to half,and the co-occurrence network diagram of authors in knowledge absorption and outflow also reflects a low degree of cooperation between authors.Except for individual authors who form a relatively fixed cooperative team as the center,most of the others are small-scale or independent authors.This phenomenon leads to insufficient knowledge exchange and knowledge blockage among scholars,which in turn affects the effectiveness of knowledge output.(3)Among the highly productive authors and institutions of knowledge carriers,sports professional colleges and universities perform more prominently,and regardless of the author,publication type,theme of knowledge absorption and outflow,or the knowledge flow between disciplines,sports scholars,sports journals,sports related themes,and sports disciplines all occupy the main position,The field of physical education has played a major role in the research and flow process in this field,indicating a lack of knowledge mobility. |
