Abstract
The human basic movement of everything is standing by the sole of the foot, it is important factor to keep the well-balanced posture and move myself. In childhood, it is a crucial time to walk myself, and especially their foot’s a skeleton and body. They develop the contact surface of foot sole and the arch of a foot while man develops walking myself. However, there are man who develop slow the formation the contact surface of foot sole and make rear center of gravity in young children and students of elementary school. There were the relationship between the contact surface of foot sole and physical fitness/motor ability for student’s of elementary school 10-20 years ago. But they have been changing life style recently, it have not been reporting. The purpose of this study was to examine the formation of the contact surface of foot and physical fitness/motor ability in young children (n=216, 124boys, 92girls) and student’s of elementary school (n=569, 1-6th grade, 279boys, 290girls).
As a result, it was relationship between the formation of the contact surface of foot sole and physical fitness/motor ability in a child under school age. A flat-footed wasn’t motor ability, and tended to be a good Kaup’s index. It was suggested that it is important to measure the formation of the contact surface of foot sole and the arch of a foot in childhood.
