军队院校毕业班学员的人体成分检测

目的：通过测量军校毕业学员的人体成分,探讨军校毕业学员与普通居民的区别,并为建立相关标准提供依据。方法：按飞行院校、分流院校、合训院校、技术院校和士官学校分层抽取5968名毕业学员,分别进行人体成分检测,根据结果划定5%-95%分布上下限。并就军校毕业学员的体脂百分比、体质指数（BMI）、肌肉百分比、骨质百分比指标与同年龄、同性别城乡居民进行比较。结果：1军队院校毕业学员体脂百分比的参考值范围为10.3%-20.7%（男）和19.2%-30.1%（女）;BMI参考值范围为19.30-25.70（男）和18.00-23.99（女）;瘦体重百分比参考值范围为79.3%-86.7%（男）和69.9%-80.7%（女）;肌肉百分比参考值范围为74.2%-84.0%（男）和65.2%-75.3%（女）;骨质百分比参考值范围为5.0%-5.8%（男）和4.7%-5.5%（女）。2与同年龄、同性别城乡居民比较,军队院校毕业学员的体脂百分比明显较少,肌肉百分比、骨质百分比明显较高。结论：1军队院校毕业学员的身体成分数据明显优于同年龄、同性别城乡居民,总体表现为体脂较少,肌肉和骨质较多。2军队院校毕业学员的体质状况不能简单采用民用标准,需建立一套符合军校毕业学员的标准。

Research on body composition of soldiers in the graduating class of armed services colleges

Objective： To master the distribution of male and female soldiers＇ body composition with bicelectrieal impedance analysis （BIA） method in order to provide data for building up the standards in comparison with those of ordinary residents. Methods： A cluster stratified sample of 5968 graduated soldiers among different armed services colleges was measured by BIA. Five percent - 95 % distributions with in the upper and lower limits were established on basis of the above resuh. The crosswise comparison was also performed. Results： ① Five percent -95% reference ranges of people in the graduating class of armed services colleges were body fat percentage （BF%）： 10.30% - 20.70% （male）and 19.20%- 30.10% （female）, body mass index （BMI）： 19.30-25.70 （male） and 18.00- 23.99 （female）, lean body mass percentage （LBM%）： 79.27% - 86.69% （male） and 69.89% - 80.69% （female）, muscle percentage （M%）： 74.24% - 83.96% （male） and 65.23% - 75.27% （female）, bone percentage （B%） ： 5.01% - 5.77% （male） and 4.65% - 5.51% （female）. ②Soldiers in the graduating class of armed services colleges have less BF%, more B% and M% than those of ordinary residents in the same age and the same sex. Ctmehttdon： ① Soldiers in the graduating class of armed services colleges have better body composition than that of ordinary residents in the same age and the same sex; ② Standard of body composition for soldiers in the graduating class of armed services colleges should be different from that of ordinary residents, a new standard should be built up.
