摘要
对北京市海淀区五所中学中1987年9月至1988年8月出生的男生457和三所小学中1989年9月至1990年8月出生的女生450人拍摄了X射线骨龄片,并请专家按CHN法对每张骨龄片进行了判别,从中筛选出了男、女生早发育组、正常发育组、晚发育组每组30人,共计180人作为实验对象,对实验对象进行体格测试并计算他们的形态指数,较好的了解了青春发育突增期三种发育类型学生的形态特征,为提高青春发育突增期学生的体质状况提供了依据。
This study conducted X-ray photographs tests of left hands in a sample of 450 girls who were born in September 1989 to August 1990 from three primary schools and 457 boys who were born in September 1987 to August 1988 from five middle schools in Haidian District in Beijing. Based on CHN method, the relevant experts were invited evaluate skeleton ages and selected !80 students as the experiment subjects, who are classified into early developed group, normal developed group and postpone developed group for both girls and boys （30 for each group）. Fitness indexes of the experiment subjects were tested and the morphic exponents were measured. Based on the test data, this study aims to make a better understanding about morphic characteristics of the students who are in the adolescent growth spurting of three different types thereby providing basis for improving fitness of the growth spurting adolescent.
