摘 要:我们调查了吉林省620名7—16岁满族学生的上、下肢长度及围度等21项体质指标,所得数据均经统计学处理。结果表明,各项体质指标在生长发育过程中多数是男生大于女生,不同年龄组增长速度不同,同年龄组男女生增长速度也不同。长度指标在生长发育中均出现两次交叉现象。这些与青少年的生长发育特点是相一致的。Six hundred and twenty Man nationality students living in Jilin province from 7 to 16 years old have been investigated. The measurementsinclude (1) length of upper arm, foream, hand, thigh, leg and foot;(2) crista iliaca height; (3) breadth of bitrochanterion, hand and foot;(4) the maximum cirumference of upper arm, forearm, thigh and leg,the least circumference of upper arm, forearm, thigh and leg. The reults show that the various measurements increase with age,means of the most items of female students are less than those of the maleones and there is significant difference (P< 0.01) at 16 years old.There are two cross phenomena (the first at 10 years old, the second at 12 years old in upper limb; at 9 years old and 13 years old in lower limb) in the length between male and female students.
