192 males and 173 females, aged from 9 to 18 years, living in mountainous farm villages were subjected to the allometric analysis of their physical working capacities. The purpose of this study was to find out in what power the various physical parameters should develop with y = a X h^b the basic linear dimension of the body height. The functional formula used for this analysis was y = a x h^b, in which y represents the estimated values of parameters and h is body height, and a and b are constants, and in the last, b might be considered to be the coefficient of physical growth and development. The results obtained were as follows: 1) Body height and chest circumference increased nearly proportionally to the theoretical value of b; 2) Vital capacity increased with theoretical value (b = 3) for males, but females showed smaller value than the theoretical one, that was 2.618. This implied that, in spite of the static and anatomical measurement, the vital capacity for females was more influenced by the respiratory muscle strength. 3) Muscle strengths in finger flexors and knee extensors developed far greater than the theoretical value (b = 2) and males exceeded females consistently in all groups of muscle strengths; 4) In comparing right with left, finger flexors and elbow flexors, except in the case of male's finger flexors, showed that right is superior to left. This seemed to be due to the differences in the frequency of using in daily life. It was substantiated by the fact that no difference was found in knee extensors; 5) Pulmonary ventilation V_E in the maximal effort increased with the 2.207 power of height for males and the 1.399 power for females, and the difference between the sexes was larger than that in the case of vital capacity; 6) Maximal oxygen uptake (V^^.o_2max) increased with the 2.872 power of height for males and the 2.420 power for females, and the values of the present study were identical with Asmussen's ones for the sexes; 7) No difference was found between the younger and the older groups in body height for each body height group for males, but, in such functional parameters as muscle strength and maximal oxygen uptake, significant differences were found, and in the age-wise the difference in maximal oxygen up-take for 150-160 cm. body height group was significant and showed the essential development of aerobic work capacity
