Analysis of the relationship of growth of body composition, somatotype and biological age to motor development.

这份报告分析了体型/身体成分的生长与运动发育的关系。受试者包括筑波初中的253名女孩和262名男孩。按Heath-Carter人体测量法测量体型。用生物阻抗法测定体脂湿重百分比。运动发育采用MEXT运动测试，女生以内胚层体型为主，男生以中胚层体型为主。内胚层女孩比外胚层女孩在摄取和峰值速度上表现出更早的年龄。对体脂百分比的分析也得到了类似的结果。男生体型与身体成熟的关系没有明显的特征。通过电池体型/体成分生长率与电池运动成绩比生长率的典型相关综合分析，内胚层增多与有氧能力降低呈正相关。偏相关分析显示，中胚层的增加与静态力量或全身力量呈负相关。青春期体力活动的改变不会影响体型或运动发育的改变。

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.
