This study was designed to predict the competitive aptitude of the excellent judoist with the morphological variables. Twenty-eight items, which were selected from the Standard Physical Fitness Test of Judoist developed by the Association for the Scientific Studies on Judo, Kodokan, were administered to 85 excellent judoists of none weight classification class, who participated in the All Japan Judo Championship Competition. And then, regression-discriminant analysis was applied so as to formulate the prediction of their performances. From the investigation in the accuracy of the formula obtained, the following results were obtained ; 1) With the morphological variables, competitive aptitude of judoist can be predicted at about 60 percent level precision. 2) The following variables were selected as the most useful predictors; Body weight(X_1), Thigh girth. L(X_2), Thigh girth. R(X_3), Skin fold fat(arm)(X_4), Wrist girth. R(X_5), Lower length. R (X_6). Then, index(Y) for predicting the competitive aptitude of judoist was devised as follows: Y^^^ =0.024X_1+0.023X_2-0.058X_3+0.024X_4-0.150X_5+0.027X_6+0.743, X_i(i=1, 2, .., 6) stands for the above mensioned variables, respectively.
