为了解南方部队在炎热条件下野营演习期间的营养状况及存在问题,于某部1982年8～10月较大规模的军事演习中,选择了3个连队在野营前期(9月)和后期(10月)进行了两次营养调查,内容有:膳食调查(称重法,连续5天)、热能消耗调查(生活观察法)、身体测量(身长、体重、上臂肌围)、营养缺乏症检查及生化检验(血红蛋白、血清总蛋白、维生素B_1、B_2、C负荷尿排出量),结果如下。一、热能与营养素摄入量前后两次调查热能摄取量均在3,000千卡(Kcal)左右(表1),野营前期演习准备阶段,热能消耗量亦在3,000Kcal左右,基本达到平衡。但在后期正式演习中,消耗量平均为3,869Kcal,最高达4,046Kcal,热能负900Kcal左右。营养素摄入量(表1)与我军原供给量标准比较,除磷,铁、硫胺素和烟酸达到标准外,蛋白质仅达80%左右,优质蛋白占总量的23.3%;钙、维生素A、核黄素分别为标准低限的73～84%、68.5～78.1%、48～73%,抗坏血酸在初期为标准低限的63.3%,后期叶菜增多,达到标准。
In order to understand the nutritional status and existing problems of the southern army during the camping exercise in hot conditions, three large-scale military exercises from August to October 1982 were chosen by the three companies in the period of early camping (September) and later stage October) carried out two nutrition surveys, including: dietary surveys (weighing method for 5 days), thermal energy consumption survey (life observation), body measurements (length, weight, upper arm muscle circumference), nutritional deficiencies And biochemical tests (hemoglobin, total serum protein, vitamin B_1, B_2, C load urinary excretion), the results are as follows. First, the caloric intake of both heat and nutrient intake before and after the survey were 3,000 kilocalories (Kcal) (Table 1), pre-camp preparation stage, the thermal energy consumption is also around 3,000Kcal, the basic balance. However, in the latter part of the formal exercise, the average consumption is 3,869Kcal, up to 4,046Kcal, thermal energy is about 900Kcal. Nutrient intake (Table 1) Compared with the original supply standard of our army, except for phosphorus, iron, thiamine and niacin, the protein reached only about 80% and the high-quality protein accounted for 23.3% The levels of vitamin A and riboflavin were 73-84%, 68.5-78.1% and 48-73% of the standard lower limit respectively. Ascorbic acid was 63.3% of the standard lower limit in the initial stage, and increased in the late stage, reaching the standard.
