The Frontiers and Hotspots of Global Judo in the Last Decade: A CiteSpace-Based Visualization Analysis

Judo, founded by Jigoro Kano in 1882, originated in Japan and has since grown to be globally popular. Young people display a high level of involvement in judo practice, while research on the sport varies over time and participation. In this study, we utilized the CiteSpace software for literature visualization and analysis. We set the time slice to 2012-2022 with a yearly increment and selected “Node Types” including “Country”, “Institution”, “Author”, and “Keyword”, with “Top N”=50. The other values remained at their default settings, resulting in the generation of a relevant knowledge graph. The LLR algorithm, which stands for Logarithmic Great Likelihood Ratio, is used to cluster keywords. Timeline, landscape, and burstiness demonstrate the temporal and sudden keyword changes. This study summarizes the research hotspots and development trends of global Judo programs in the Web of Science core collection in the last decade.
