Abstract
In this study, we analyzed match videos of a university Judo Player (Player A) utilizing the SPLYZA TEAMS matched video analysis tool. This is the first case study of Judo match analysis using the SPLYZA TEAMS software. A total of 13 matches involving Player A were analyzed in this study. Prior to the analysis, Player A formulated three hypotheses for the matching implementation. The analysis rejected two of the three hypotheses established at the beginning of the study. However, a notable trend emerged, revealing a proclivity for the Kumite situation for initiating Nage-waza from disadvantaged positions in matches that resulted in a loss. This novel finding was obtained by analyzing the data using the SPLYZA TEAMS software.

Judo is a Japanese martial art that was established in 1882 by Jigoro Kano. Judo practitioners wear Judo-gi, and engage in dynamic contests using Nage-waza and Katame-waza to assert dominance over their opponents. Since its recognition as an official sport at the 1964 Tokyo Olympics (Murata, 2011), judo has garnered international recognition, reaching over 200 countries and regions (International judo federation, 2023), making it a familiar facet of Japanese culture worldwide.
