南北地区武警战士、学员身体发育状况的研究

目的：了解不同地区武警部队士兵的身体发育状况，为部队选兵、体质评价和人体功效学提供基础资料。方法；对1014名南北地区武警战士、学员进行调查研究。将身体发育指标作因子分析，确定权重系数，计算 发育分，按南北地区和性别进行分类比较。结果：南北地区战士、学员的发育分：男性分别为98．05、100．95；女性分别为98．15、101．13。南北方同性别发育分进行比较，北方高于南方，经u检验、p值小于0．01，差异非常显著。结论：不同地区部队战士、学员身体发育的差异与地球纬度的高低和诸多的气候因素有关。

INVESTIGATION ON THE PHYSICAL DEVELOPMENT STATE OF SOLDIERS AND STUDENTS OF ARMED POLICE FORCES FROM THE NORTH AND THE SOUTH OF CHINA

Objective:To study the physical development state of soldiers in armed police forces, so as to provide basic data for selection of soldiers,physical quality evaluation and human ergonomics.Methods:1 014 soldiers and students of armed police forces from the north and south of China were investigated.The weighted coefficients were obtained by factorial analysis on physical development indexes(height,body weight and chest measurement).Physical development scores were calculated. The data were compared by classification according to the north and south region as well as the sex of these subjects.Results:The physical develoment scores of the south and the north were 98.05,100.95 respectively(P<0.01) in male and 98.15,101.13 respectively (P<0.01) in female,indicating that the physical development scores of north subjects were significantly higher than those of south subjects in both sexes.Conclusion:There were regional differences in physical development between the north and south soldiers and students of army,which may by related to the latitude of the earth and the climatic factors.
