Number of reports concerning the physique of the various athletes have been reported. The present study aims to clarify the interspecific allometry relation among several sports categories, because the analysis by allomorphosis has not been previously attempted. The materials Used in this study are anthropometrical data of the athletes on 15 sports categories in male and 9 sports categories in female from the Report of Physical Fitness Tests on the Representative Athletes of Japan in Universiade Sunmmer Event (1967) published by the Japanese Amateur Sports Association. In double logarithmic grid papers to indicate the allomorphosis relations, stature is taken as abscissa (x) and the other 5 items are ordinate (y). Straight relations (tribes) are drawn paralleled to the regression lines to indicate the relative variations on non-specially trained young peoples (Hattori and Sawaki, 1971). From the results indicated as the scatter diagrams on log-log papers (Figs. 1〜10), the findings are summarized as follows. In body weight, the heavier class in Judo has a tendency to be biased to the higher tribe than the lighter one. Gymnastics in both sexes locate lower tribes nevertheless they have conspicuous muscular types on physique. In sitting height, sole tribe can be identified. In chest girth, fencing, volleyball and basketball in male situated the lower tribe, on the other hand long distance run and gymnastics in male and swimming in female transit to higher tribes in comparison with the result of body weight. Swimming in both sexes show relatively (allomorphosis point of view) large forearm and small upper arm and reverse relation can be observed in tennis players.
