1985—2010年武陵山区土家族学生身体形态发育的动态分析

Body Shape of Tujia Students in Wuling Mountain Area from 1985 to 2010

利用1985—2010年间武陵山区土家族学生的身体形态测试数据,对身体形态指标、青春突增年龄、身体发育速度等情况进行对比和动态分析,探索少数民族地区青少年的身体形态发育规律。研究结果表明,近25年间,武陵山区土家族学生身高、体重出现明显增长。但是武陵山区土家族学生胸围的增长幅度不大,特别是男生部分年龄组出现负增长,与肺活量下降的趋势基本一致。土家族学生突增高峰年龄出现比较明显的提前现象,突增高峰年龄的性别差异比较明显。土家族学生的2010年身高速度高峰、体重速度高峰、胸围速度高峰的发育高峰值明显大于1985年,但发育的速度都出现了比较明显的减慢趋势。

The paper aims to make contrastive and dynamic analysis through the information of body shape of Tujia students in Wuling Mountain area from 1985 to 2010 ,especially according to the aspects of body shape indicators, age of sudden increase and the development speed of bodies,in order to have a further research on the law of body development. The results showed that height and weight of Tujia students in Wuling Mountain area had significant increase in 25 years. However, the growth rate of their bust was not big. Especially, boy age group has obvious negative growth, This is basi- cally the same with the decline trend of their FVC. There is a phenomena presented that the age of sudden increase on body shape was ahead of normal, and the sex differences are relatively obvious. The peaks for development speed of height, weight and bust of Tujia students in 2010 were significantly greater than that in 1985, but the development speed al- so showed a trend to slow down.
