Differences of physical construction between fighting Judo players often exert serious effects on the result of the match. However, some competitions in Japan are carried out regardless of considerating the constitutional differences, especially weight difference. It is important to examine the effects of constitutional differences on the match, since need of the open-weight class is discussed in the international Judo competitions.In this study, the effects of the constitutional differences (height and weight) on the Judo matches were investigated by analysing the success of the all Japan Judo championship competitions from Showa 55th (1980) to Heisei 1st (1989)The maior findings obtained were as follows:1. There was no significant difference in the number of victories between taller and shorter players in.32,2, matches in which difference of height was appreciated. Slight advantage was found in taller players, when the difference of body height was 6 cm or greater.2. When the difference of body weight was less than 20kg, there wes no effect on the success of the matches. In the matches with weight difference of 20-40kg, heavier players tended to be superior to lighter players, but the ratio of the success of match was 153: 128, indicating no significant difference. It is clear that when the weight difference was more than 40kg, heavier players was advantageous.3. Both the weight and the height differences show no effect on the success of the matches at the first half of the tournament (the 1st and 2nd tournaments), but at the second half of the tournament (from 3rd tournament to the final) heavior players were easier to win than lighter players.4. The main difference was observed in the number of “Ippon”, in the win of the matches between players with superior and inferior constitutions.In summary, it is suggested that most of participants (ca.74% of all) can have an equal opportunity of success in the all Japan championship competition. This may justify the existence of the Judo competition without distinction of weight.
