Hello, I am Daniel Lee. As a lifetime Judoka, I donate my free time to judo.
I created judocare to bring innovation to Judo. Through this internal improvement, I hope to attract and retain more athletes, coaches, spectators, and sponsors to judo. JudoCARE is a video arbitration tool to help make sure the right player gets the win. Through this internal improvement, we aim to attract and retain more athletes, coaches, spectators, and sponsors to judo. JudoCARE is among the world's largest providers of video analytics systems used in referee arbitration in the sport of Judo. Customers include major NGBs and elite national and international point tournaments in continents Asia, Europe, N.America, S.America, India, Africa and Australia.
PURPOSE
The new CARE will provide innovative referee training opportunities resulting in improved referee performance during tournaments. Judicial use of CARE will lead to a better image of referees among players, coaches, and spectators. We may someday achieve referee professionalization. Through this project, I aim to establish a revolutionary CARE-based training center. It will use state-of-the-art digital technologies for reviewing actual judo situations to support education and further training and development of referees. The suggested methods will enable us to achieve higher accuracy of decision-making and improve the fairness of matches. The CARE-based training will prevent speculations and guesses concerning the appreciation of a technique. It will be useful to coaches, referees, and most importantly the players. All in all, judo wins.

Abstract
The understanding of time-motion and physiological responses to judo combat is important to training organization. This review was based on search results using the following terms: “judo and competition”, “judo and physiology”, “judo and randori”, and “judo and time-motion analysis”, “judo and combat”, “judo and match” and “judo and biochemestry”. The effort-pause ratio during judo combats is between 2:1 and 3:1, with 20s and 30s effort periods and 10s of pauses. Thus, judo combats rely on all three metabolisms, with the anaerobic alactic sytem being reponsible by the short duration powerful actions during technique applications, the anaerobic lactic system being responsible for the maintainance of high-intensity actions during longer periods (e.g., grip dispute), while the aerobic system is responsible for the recovery processes between high-intensity actions and matches. Training prescription must consider these demands and a muscle-specific action analysis may help to direct the proper approach to improve judo athletes’ performance. In general, lower-body is involved in short-term high-intensity actions during technique executions, while upper-body muscle groups are involved in both strength-endurance and power actions. As many muscle groups perform different actions during the match, a high cardiovascular demand is also observed in judo.

Abstract
In this second paper on match analysis, we analyze in deep the competition steps showing the evolution of this tool at National Federation level. On the basis of our first classification, Match Analysis is a valuable source of four levels of information: 1st. Athlete’s Physiological data 2nd. Athlete’s Technical data 3rd. Athlete’s Strategically data 4th. Adversary’s Scouting Furthermore, it is the most important source of technical assessment. Studying competition with this tool is essential for the coaches because they can obtain useful information for their coaching. Match Analysis is today the master key in situation sports like Judo, to help in useful way the difficult task of coach or best for National or Olympic coaching equips. In this paper it is presented a deeper study of the judo competitions at high level both from the male and female point of view, explaining at light of biomechanics, not only the throws evolution in time ( introduction of Innovative and Chaotic techniques) but also the evolution of fighting style in these high level competitions, both connected with the grow of this Olympic Sport in the Word Arena ( today 199 countries are members of IJF) It is shown how new interesting ways are opened by this powerful coaching tool, very useful for National team technical management. In the last part of this paper we analyze advanced mathematical tools describing Couple of Athletes motion as Fractal Poisson Point Processes based on Fractional Brownian Motion to show how strategic evaluation , probability and short term forecast can be applied to Judo competition.
