Purpose: Modern Judo has developed with traditional techniques, changes in game rules, and increased international exchange. Recently, the rules have changed to a more aggressive direction, and coaches are studying new techniques inspired by Russian Sambo and Brazilian Jiu-Jitsu (BJJ). Accordingly, Judo training must become more scientific and systematic through data and video analysis. Therefore, this study was conducted to analyze the use of techniques by Korean middle and high school and university judo players to maintain international competitiveness in line with these changes. Method: First, the frequency analysis was performed to examine and understand the general characteristics by using the SPSS/PC+23.0 program. Second, to validate the reliability of the survey questionnaire, the Cronbach's α coefficient was calculated. Third, exploratory factor analysis was conducted to find out the structure of the use of attack and defense techniques by judo players. Fourth, correlation analysis was conducted to find out the relationship between the use of attack and defense techniques by judo players. Fifth, regression analysis was conducted to find out the effect of the use of attack techniques by judo players on the use of defense techniques. Results: The results of the correlation analysis of the use of attack and defense techniques by judo players showed a statistically significant correlation of r=0.470, p=0.000, and a simple linear regression analysis was conducted to determine whether the use of attack techniques affects the use of defense techniques. The results showed F=55.000(p<.001), indicating an explanatory power of 22.1%. The use of various techniques by judo players can be explained by strategic diversity in their performance, complementary techniques, responding to various situations, strengthening body parts, improving endurance during the game, and weakening the response ability of opposing players. Conclusion: In judo, the attack and defense techniques are Kuzushi (breaking the balance) - Tsukuri (taking the body position) - Kake (throwing), and each step has a direct and very important effect on the performance. However, in the recent era of artificial intelligence, artificial intelligence is being applied to all sports, and Korean judo must develop judo by combining traditional technology with a scientific approach as an IT powerhouse. To this end, it is necessary to utilize artificial intelligence image data analysis, virtual and augmented reality simulation training, motion capture technology, and AIbased customized training programs to provide appropriate feedback to athletes. In addition, in order to resolve the issue of controversy over match judgment, it is also an important task to introduce artificial intelligence referee judgment through international exchange programs to increase the objectivity of judo judgment. It is hoped that this study will lead the future international judo infrastructure and properly develop sports in the 4th industrial revolution.
