Abstract
Using the data on physical fitness and motor ability measured on 17, 000 school children aged 10-17, in Kyoto City, the relationship between body build and physical fitness and the relationship between body build and motor ability have been examined.
When children were classified into five groups according to their height, it was found that the tallest group had generally the most excellent physical fitness and motor ability in both of boys and girls of every age group. The items of sport test in which the tallest group did not show the best record were only chinning (modified) and continuous belly grinds.
When children were classified into five groups according to their Rohrer Index, it was found that the group of the largest Rohrer Index had the strongest muscle strength, but the group of the largest Rohrer Index and the group of the smallest Rohrer Index were generally inferior to the group of average or middle Rohrer Index in the other facets of physical fitness and motor ability. This trend was found in both of boys and girls of every age group, although the detail of the relationships between Rohrer Index and Physical fitness or motor ability were a little different by age and sex.
