The Influence of Military Training on the Body Composition and Lung Capacity of Male College Students

了解军训对男大学生身体成分及肺活量的影响.随机选取10男大学生为研究对象,通过为期15天的军事训练,测试军训前后受试者身体成分及肺活量变化情况.结果表明:军训后较军训前受试者肌肉含量、脂肪含量、身体水分、肺活量均有显著性增加(P<0.05);蛋白质含量有非常显著性增加(P<0.01);体重、BMI均有下降但无显著性差异(P>0.05).军训可改善大学生的身体成分,起到减脂增肌、增加机体水分和蛋白质含量的作用;增加大学生的肺活量,提高呼吸系统的功能.

Objective： To understand the influence of military training on the body composition and lung capacity of male college students. Methods： 10 male college students were randomly selected to study the physical and lung changes before and after the military training for 15 days. Results： There was a significant increase in muscle content,fat content,body water and lung capacity after military training（ P〈0. 05）. The protein content was significantly increased（ P〈0. 01）; weight and BMI both declined but had no significant difference（ P〉0.05）. Conclusion： Military training can improve the body composition of college students,reduce fat,increase muscle,body water and protein content. It can increase the lung capacity of college students and improve the function of their respiratory system.
