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

本报告分析了体型/身体成分的增长与运动发育的关系。研究对象包括筑波市初中的253名女生和262名男生。根据Heath-Carter人体测量法估计体型。用生物阻抗法测定体脂湿百分比。运动发育用ext运动测试进行评估。女生表现为内胚型，男生表现为中胚型。同型女生的吸药年龄和吸药速度峰值明显早于异型女生。对体脂百分比的分析也得到了类似的结果。男孩体型与身体发育的关系无显著特征。体内形态的增加和有氧能力的下降，通过对体型/身体组成的生长率和运动性能的特定生长率的典型相关性的综合分析，相互关联。偏相关分析显示，中形态的增加与静态强度或全身力量呈负相关。青少年时期体育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.
