南北方应征入伍男青年体质差异的比较

Comparative Study on the Physique Difference of the Young Men Enlisted in the North and South

目的:了解应征入伍男青年体质水平的差异性,为部队优化选兵标准、改革训练模式、科学评价体能提供理论依据。方法:测量来自我国部分省市370名应征男青年的身体形态、机能与素质,依据入伍前居住地,分为南、北方两组。结果:身高、体重、VI和BMI南北方兵差异显著;北方兵瘦体重显著高于南方兵;北方兵收缩压和舒张压显著高于南方兵;北方兵肺活量大于南方兵;南方兵最大摄氧量显著高于北方兵;北方兵的握力、背肌力、引体向上显著高于南方兵。结论:北方兵比南方兵体格更充实、强壮;南方兵身体机能略好于北方兵;北方兵力量素质明显好于南方兵。

Objective： To understand the different physique levels of enlisted male youths,to optimize the standard of soldiers selection for the army,to reform the training pattern and provide theoretical basis for scientific assessment of the physical fitness.Method： the researchers measured the body shape,physiological function,strength quality and sports ability of 370 enlisted male youths,compared the results in two groups based on their residence before being enlisted south and north.Result： There are significant difference between the two groups in heights,weights,VI and BMI.Lean body mass,systolic pressure and diastolic pressure of the northern soldiers are significantly higher than those of the southern soldier;vital capacity of the northern is larger than the southern;maximal oxygen uptake of the southern is larger than the northern;strength of grip,myodynamia of the back,pull-up of the northern are significantly higher than the southern.Conclusion： the soldiers from the north are better shaped and stronger in the physique than soldiers from the south;while soldiers from the south have slightly better physical function;soldiers from the north have significantly better strength qualities but no distinct difference of sports ability.
