摘要
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。
To find out the effects of restricted energy intake on physical fitness and survivability of soldiers. Methods: Twenty-seven soldiers were divided into three groups at random, and they were restricted to 50%,70% or 100% of normal energy intake for 10 days respectively. The indexes of physical fitness and some laboratory parameters were Abstractd within the days.Results:There were significant differences in 100 meter-running, PWC170, pull-ups, 3000 meter-running, body weight, serum triglyceride, K + and Ca 2+ between 70% intake group and 50% intake group before and after experiment.Conclusion: Restriction of energy intake would obviously influence on physical fitness activity with high intensity,and the military work in moderate intensity could be carried out by energy intake of 6875.2 kJ per day during ten successive days.
