In order to observe the physical strength in growing, it is a matter never to be neglected that the physique and also the psychological and intellectual influences must be considered. Nevertheless this sort of study has hitherto been very rare, and leaves much to be discussed.
The writer, reflecting this point deeply, investigated the growth and change of the physique under the influence of mental activity, and thus tried to grasp the actual state of the physical development.
As an object to be examined, I selected the pupils of a certain primary school in Tokyo and those- of a middle school in its neighbourhood. I made physical examinations for 7 times and practised Awaji-method inspections for the whole pupils at the beginning of each school term from September, 1950 to that in 1952. I selected 413 boys and 405 girls as thorough examined ones through the whole terms, and applied them Rhorer-Index exponent as a physical characterstic. The result and conclusion for these experiments came as follows:
For the development of physique during the growth period, psychological factors must play a pretty important part. Above all for lower class boys and girls in the primary school, for the second and third year boys in the middle school, and for the girls in the fifth and sixth year of the primary school and in the first year in the middle school, 2 could admit a reletive importance between the psychological operations and the growth of the physical constitution.
