CiteSpace-based Visualisation Analysis of Karate Athletes’ Characteristics of Technique Usage

With the rapid development of the world karate program, the international competition situation is becoming more and more intense, and the techniques and tactics are gradually moving from single to multiple. This paper uses CiteSpace and kinematic parameters to visualize and analyze the technical movement characteristics of karate. Based on the point and angle parameters in kinematics, the movements of karate athletes on the field are expressed in the form of coordinate points. Scientific knowledge mapping was used to transform the characteristics of karate athletes’ technical use from abstract concepts to diagrams with practical significance and to realize the tactical analysis of the use of karate techniques by players of different weight classes. The results showed that among the movement techniques 571, the most frequently used technique was boxing, followed by kicking, combination techniques, and wrestling, with 265, 197, 35, and 84 times, respectively. In terms of technique success rate, boxing technique had the highest success rate of 40.6%, while leg technique was second with 35.3%. Out of 2344 boxing techniques used, the middle back fist technique was used 1034 times, and the upper back fist technique was used 850 times, which were the two most used techniques.
