The Hotspots of Sports Science and the Effects of Knowledge Network on Scientific Performance Based on Bibliometrics and Social Network Analysis

In this study, we sorted out the research hotspots in sports science by bibliometric method and also used social network analysis to explore relationship between knowledge networks their scientific performance. We found 38 high-frequency keywords with obvious curricular nature or classical direction of 4 groups. The topics covered secondary disciplines science: physical education training, national traditional sports, human science, humanities sociology. However, is less; therefore, accelerating focus future research. Meanwhile, use structure (i.e., centrality, clustering coefficient, PageRank, structural holes) study elements addition betweenness closeness holes are significantly positively related influence. productivity, centrality show significant positive correlations, coefficient hole negative correlations. Therefore, can be predict performance elements.
