Study on the effect of physical constructional differences on Judo match in quite interesting in connection with problems of continuance of the open-category and meaning of competition without considering weight difference. In our previous report on this matter, effects of height and weight differences between competing Judo contestants were examined mainly from viewpoint of consequence of competition. In this paper, in order to further examine the effects, relationship between physical constructional differences and details of competition, especially Judo technique and duration of contest required for victory, was studied based on the analysis of the results of the all Japan championship competitions from Showa 55th to Heisei 1st. The following results were obtained:
1) Leg technique was most frequently used for victory in either taller or shorter players. Significant difference between numbers of victories of the taller and shorter players was due mainly to the number of leg techniques.
2) In the case with weight difference, significant difference in the number of all techniques for victory was observed where heavier players were always advantageous. Furthermore, physically superior players most frequently obtained the victory by using yokoshiho-gatame, while physically inferior players most often obtained it by kamishiho-gatame.
3) Uchimata was the most effective technique to get the victory among throwing techniques.
4) The mean match time required for victory by ippon was similar between taller and shorter players. Lighter players often required prolonged match time to get victory rather than heavier players did.
5) In correlation between weight difference and the required match time, a very small negative r value was obtained: a very small positive r value for throwing technique and a small negative r value for katame-waza.
From the results obtained in this study, effective techniques for the physically superior or inferior, for victory were clarified.
