目的研究在高温高湿环境下运动对人体血红蛋白和红细胞比容的影响情况。方法随机选择90名南沙巡防区战士,分成老战士组、新战士组、新战士服药组3组,在高温高湿环境下20 min内跑步3 000 m,分别抽血测定跑步前后的血红蛋白和红细胞比容的改变。结果跑步前3组战士之间血红蛋白和红细胞比容的结果没有显著差别,而跑步后3组之间血红蛋白和红细胞比容的结果有显著差别。结论高温高湿环境下运动对人体血红蛋白和红细胞比容有较大的影响,由于新老战士在高温高湿环境生活的时间长短不一样,因而他们对高温高湿环境表现的耐受力和适应情况不同,而且口服乌拉地尔片剂可以明显减小运动前后的血红蛋白和红细胞比容改变。
Objective To study the effect of exercise on hemoglobin and hematocrit in hot and humid environment. Methods Ninety Nansha patrol soldiers were randomly selected and divided into three groups: veteran group, new warrior group and new warrior drug group. They ran 3000 m in 20 minutes under high temperature and high humidity. Blood samples were collected to measure hemoglobin and erythrocyte before and after running Specific volume changes. Results There was no significant difference in the results of hemoglobin and hematocrit among the three groups of soldiers before running, while the results of hemoglobin and hematocrit were significantly different among the three groups after running. Conclusions Exercise under high temperature and high humidity has a great impact on hemoglobin and hematocrit in human body. Because of the different length of life of new and old soldiers in high temperature and high humidity environment, their tolerance and adaptation to high temperature and high humidity environment The situation is different, and oral urapilil tablets can significantly reduce hemoglobin and hematocrit changes before and after exercise.
