招募体检筛选工作中的人体成分检测

目的对人体成分检测在征兵工作中的应用进行研究,探讨人体成分检测和体能水平的相关性；方法选取662名应征青年,对其进行人体成分检测,并对其中633名进行3 000米体能测试,分及格组和不及格组进行t检验；结果①体脂百分比的参考值范围为10.50%～21.50%（男）和20.40%～31.70%（女）；BMI参考值范围为18.70～25.40（男）和18.00～24.00（女）；瘦体重百分比参考值范围为46.90%～65.10%（男）和37.60%～47.60%（女）；骨骼肌百分比参考值范围为31.40%～43.90%（男）和24.80%～30.90%（女）；②分别对3 000米跑及格组和不及格组进行均数比较,体脂百分比差异有统计学意义（男：p=0.0004,女：p=0.6135）；BMI差异无统计学意义（男：p=0.0827,女：p=0.4295）；瘦体重百分比差异有统计学意义（男：p=0.0001,女：P=0.0227）；骨骼肌百分比差异有统计学差异（男：p=0.0002,女：p=0.0003）。结论①应征入伍青年人体成分分布上相较于国外应征青年仍有差距；②单纯采用BMI并不能对体能水平进行判断；③瘦体重和骨骼肌百分比更能反应应征青年的体能水平。

Research on Body Composition Detection in Recruitment Physical Examination

Purpose To investigate the correlation between body composition and energy level;Methods A sample of 662 inductees was measured by BIA.3 000 m run was also tested.T- test was performed between pass inductees and fail inductees;Results ①5%～95% reference range of Body Fat Percentage（BF%） were：10.50%～21.50% for female,and 20.40%～31.70% for male.Body Mass Index（BMI）：18.70～25.40 for female,18.00～24.00 for male.Lean Body Mass Percentage（LBM%）：46.90%～65.10% for female,37.60%～47.60% for male.Bone Muscle Percentage（BM%）：31.49%～43.90%/24.80%～30.90% for male.;②There was difference between pass and fail inductees in these items：BF%（male：p=0.0004/ female;p=0.6135）,BMI（p=0.0827/p=0.4295）,LBM%（p=0.0001/p=0.0227）,BM%（p=0.0002/p =0.0003）;Conclusion ①There are gaps in body composition between inductees at home and abroad;②BMI can＇t tell the physical capability level singlely;③LBM%and BM%would be good indicators for evaluating inductees＇ energy levels.
