Abstract
The gravity center and the relative gravity center of the human body have been determined on the following groups of subjects : the pregnant women in their 20s to 30s, being at 2 to 10months of pregnancy ; the laborers in their 20s to 40s, non-laborer in the same age range ; the feeble-minded and crippled children and adults. 1) Correlations of height and weight of the body and the chest girth as contrasted to the gravity center and the relative gravity center of the body It was revealed that in every instance measured for the items above mentioned, the gravity center increased its height in parallel with the increase in the body weight, body length and chest girth, without showing any appreciable change in the height of the relative gravity center. There was no sex difference in this respect 2) The correlations between the relative body weight, relative chest girth and relative height of gravity center In every items measured, it was revealed that the value for the relative height of gravity center remained approximately constant regardless of the magnitude of value obtained from the relative body weight or of the relative chest girth. 3) From the data obtained it was concluded that there wass carcely found any appreciable difference in the position of gravity center among the subjects regardless of whatever physique they had.
