962 male inhabitants aged from 30 to 60 in Kanto district were tested on their physique and physical fitness. The results were as follows.
1) So their weight was havier than those of nations but on their height relatively that their Rohler's Index was biger than that of nations.
2) Their motor ability was generally inferior than that of nations, especially it was remarkable on the subject on their thirties.
3) The subjects who was superior on the ability of 5 minutes running had the biger Rohler's Index and larger skinfold than that of inferior one.
4) Persons who had less skinfold were inferior on their other physical activities.
5) The subject who had the skinfold ranged from 25mm to 39mm (i. e. had 14-21 percentage fat to their weight) showed highest ability with the running distance within 5 minutes, backward flexibility and vertical jump.
6) It seems to me that the meaning of forward flexibility as the item of physical fitness should be discussed further more after a lot of investigations.
