目的 :了解军人在各种应急条件下能量摄入不足时对军人体能及生存能力的互相关系 ,为平战时食品配发与管理提供科学依据。方法 :选择 2 7名战士随机分成 3组 ,分别按标准量 10 0 %、70 %或 50 %限摄能量 ,连续 10d ,观察各组战士体能及生化指标变化情况。结果 :70 %摄入组与 50 %摄入组的 10 0m跑、PWC170 、引体向上、3km越野跑及体重等实验前后存在显著性差异 ;生化检验显示 ,70 %摄入组与 50 %摄入组血清甘油三酯、钾、钠实验前后有显著性差异。结论 :限摄能量对大强度体能活动有较明显的影响 ;摄入 50 %标准量 ,连续 10d ,军人仍能基本完成中等劳动强度的军事作业活动。
OBJECTIVE: To understand the military interrelationship between physical fitness and survivability of military personnel in the event of insufficient energy intake under various emergency conditions, and to provide a scientific basis for the distribution and management of food during World War II. Methods: Twenty-seven warriors were randomly divided into three groups. The energy was limited to 10%, 70% or 50% of the standard amount respectively for 10 consecutive days. The changes of physical fitness and biochemical indexes in each group were observed. Results: There was a significant difference between 70% intake group and 50% intake group before and after 10 0m running, PWC170, pull-ups, 3km cross-country running and body weight. The biochemical tests showed that 70% Into the group of serum triglyceride, potassium, sodium significant differences before and after the experiment. CONCLUSION: The limiting energy has a significant effect on high intensity physical activity. The intake of 50% of the standard volume for 10 days continuously enables the military to basically complete medium-intensity military operations.
