摘要
目的 观察飞行训练员被试者在缺氧与高温负荷下智能功效的改变及航宝营养液的抗心理疲劳作用。方法 受试者为 15名健康青年飞行训炼员 ,随机分为试验组 (10名 )和对照组 (5名 )。试验组航宝营养液 10ml,bid ,po ,共服 30d。对照组服用安慰剂 ,方法同试验组。分别在用药前和用药 30d接受高温舱 (38℃ )低氧混合气 (14%氧氮混合气 ,相当于 30 0 0m高度 )试验 ,检测暴露于该负荷下 10min和 6 0min时的人体功效指标。结果 试验组用药后暴露在高温与缺氧复合负荷下 10min和6 0min的双手组合操作按键正确次数为 5 0 .92 %± 15 .93%、5 0 .40 %± 13.40 % ,明显高于用药前 2 9.19%± 8.36 %、2 8.49%± 7.74% (P <0 .0 1) ;二维补偿跟踪试验成绩为 2 2 .2 0± 6 .37、17.0 0± 7.16 ,亦比用药前 15 .0 0± 7.42、11.2 0± 6 .31有改善 ,但不及双手组合操作明显。而对照组用药后各项指标无明显变化 (P >0 .0 5 )。结论 航宝营养液具有一定提高机体缺氧耐力和抗心理疲劳的作用。
Aim Hypoxic tolerance and intelligential efficiency of flying trainers are reduced remarkably during combined hypoxia and heat stresses.The judgement and performance are affected.The purpose of this study is to observe the changes of intelligential efficiency of the subjects during the stresses and the effects of Hangbao Yingyangye on psychological fatigue.Methods Fifteen healthy male flying trainers served as the subjects,and they were divided into experimental group (n=10) and control group (n=5).For the experimental group,Hangbao Yingyangye was given orally (10ml bid) for one month,and for the controls placebo was used instead. Inhaling low-oxygen gas (14% oxygen-nitrogen mixture) and heat chamber test(38℃) were conducted before and after administering a course of Hangbao Yingyangye (or placebo).The ergonomical indexes of the subjects were examined after 10 and 60 min exposed to the combined stresses.Results In experimental group,compared with initial value(29.19%±8.36%,28.49%±7.74%),correct rates of the two hand operations after 10 and 60 min of the combined stresses were significantly increased(50.92%±15.93%,50.40%±13.40%,P<0.01 respectively),and the results of the two-dimensional compensating trace tests were improved (22.20±6.37,17.00±7.16),compared with intial value(15.00±7.42,11.20±6.31).But there no significant changes of those in the control after a course of placebo.Conclusion Hangbao Yingyangye can enhance hypoxic tolerance and resistance to psychological fatigue of human body.
