| Research Abstract |
This report analyzed relationships of growth of somatotype/body composition to motor development. The subjects consisted of 253 girls and 262 boys from junior height school at Tsukuba. The somatotype was estimated according to the anthropometric method of Heath-Carter. Percent body fat wets assessed by the method of bioinmpedance. Motor development was assessed by the Sports Test of MEXT.
Girls showed the endomorphy and boys the mesomorphy as their representative somatotype components. Endomorphy girls showed earlier ages at take-of and peak velocity than ectomorphy girls. Similar results were obtained from the analysis of percent body fat. No marked characteristics of relationship of somatotype to physical maturation for boys.
An increased endomorphs and decreased aerobic capacity correlated each other by the Integrated analysis of canonical correlation of the battery for growth rate of somatotype/body composition and battery of the specific growth rate of motor performance. Partial correlation analysis showed negative relationship between increased mesomorphs and static strength or total body power. No change of physical activity during adolescence does affected change of somatotype or motor development.
