8周的基础军训对新疆边防部队新兵人体测量指数影响的分层研究

Stratification research on the effect of 8-week basic military training on new conscripts' BMI, WC and WHR in Xinjiang Frontier Armed Police

目的:探讨新兵入伍后8周的基础军事训练,对新兵的人体测量指数的影响。方法:随机抽取新疆边防部队2013年度入警的102名男性新兵,其中汉族67名,维吾尔族35名,分别在训练前后测定并记录身高、体重、腰围、臀围,体质指数和腰臀比。结果:经过8周的基础军事训练,对所有参加测试的新兵而言,体质指数变化不大,腰臀比则显著下降。分层研究表明,经过8周的基础军事训练,体重偏轻(体质指数<18.5kg/m2)的新兵,体质指数显著增加,腰围变化不大,臀围显著增加,腰臀比不变;对于正常体重(18.5kg/m2≤BMI<25 kg/m2)的新兵,体质指数变化不大,腰围显著降低,臀围显著增加,腰臀比显著降低;对于超重(25kg/m2≤BMI<30kg/m2)的新兵,体质指数、腰围、臀围及腰臀比均显著降低。结论:新兵8周的基础军事训练,可以重塑体型,减少腹部脂肪的积聚,促进健康。

Objective To investigate the changes in body mass index,waist circumference and waist hip ratio among new conscripts after 8- week basic military training. Methods 102 new conscripts （67 han ethnic,35 uygur ethnic）of Xinjiang Frontier Armed Police were selected randomly in 2013.Height, weight,waist circumference,hip circumference,body mass index and waist hip ratio were measured and recorded at baseline and follow- up. Results After 8- week basic military training,to all the subjects,BMI has little change while WHR decreased significantly. Stratification research shows：To the underweight subjects （BMI〈18.5 kg/m2）,BMI increased significantly and WHR has little change; to the normal weight subjects （18.5 kg/m2≤BMI〈25kg/m2）, BMI has little change and WHR decreased significantly; to the overweight subjects （25 kg/m2≤BMI〈30kg/m2）, both BMI and WHR decreased significantly. Conclusion For the new conscripts,8- week basic military training plays an important role in remaking body shape,diminishing accumulation of abdominal fat and building up health.
