Abstract

Relationship between physique and motor ability of lean type in primary and junior high school boys and girls have been Investigated by means compared with middle type in correlation and multiple correlation analysis. Measurements of physique (stature, body weight and chest girth) and motor ability (50m sprint, standing jump and softball throw) were made from 6 to 14 years old boys and girls. Lean and middle types were classified by applying to regression estimation of body weight on stature by judged from results of stature, body weight and chest girth's measurements, and correlation and multiple correlation analysis between physique and motor ability in both types of them were made and validity of regression and multiple regression estimation were investigated in lean type. Growth of stature in lean type was almost similar to them of middle type in boys but in girls had a tendency that was few latter than them of middle type. Motor ability of lean type was inferior to them of middle type. Correlation between stature and motor ability of lean type in boys was significant in period of junior high school, but especially in girls correlation between stature and throwing ability was not significant at all, and multiple correlation between physique and motor ability was significant in period of junior high school but validity multiple regression estimation of motor ability on physique was not shown in boys and girls.
