摘　　要：目的:拟通过湿热环境习服性训练和抗晕动病训练两阶段,探究训练对降低晕动病发病率及等级的作用。方法:选取60名健康男性志愿者,配对分成实验组和对照组,实验组①一阶段采取模拟湿热环境静坐、快走、负重跑等训练,通过检测受试者主观感受、肛温、心率、血压、出汗率、汗盐浓度等指标确定受试者达到湿热环境习服;然后两组均在40℃、80%下进行Coriolis加速度转椅试验诱发晕动病,以Graybiel法评定晕动病得分及等级,以评价湿热环境习服训练是否可以降低晕动病发病率及等级;②三个月后实验组脱习服后进行二阶段常温下(20℃、50%)抗晕动病训练,共接受旋转转椅法训练10次,每次通过Graybiel法记录晕动病得分及等级;对照组不接受两阶段的训练。然后两组再次均进行Coriolis加速度转椅试验诱发晕动病,以Graybiel法评定晕动病得分及等级,用以评价抗晕动病训练是否可以降低湿热环境下晕动病发病率及等级。结果:①一阶段湿热环境习服训练后,实验组和对照组Graybiel评分及等级差异无显著性(P>0.05);②二阶段抗晕动病训练后,实验组Graybiel评分及等级较对照组有明显降低(P<0.01)。结论:单纯湿热环境习服训练并不能帮助降低湿热环境下晕动病的发病率和等级;但抗晕动病训练可以有效降低发病率和等级。Objective： Incidence and severity of motion sickness （MS） in hot-hmnid environment are extremely bSgh. We tried to know the effect of two-stage training for reducing incidence and severity of ms. Melhods： Sixty male subjects were divided into experimental group and control group randomly. Subjects in experimental group received： ① adaptation training including sitting, walking and running in hot lab. After adaptation confirmation based on subjective feeling, rectal temperature, heart rate, blood Pressure, sweat rates and sweat salt concentration, we tested both groups by Coriohs acceleration revolving chair test and recorded Graybiel＇ s score and grading of severity to evaluate whether adaptation training was useful; ② Anti-dizzy training 3m later of deacclimatization contained revolving chair training for 10 times. Then we did the same test as mentioned above to evaluate effect of anti-dizzy training. Resulst： Graybiel＇ s score and grading of severity had no difference between two groups through acclimatization training （ P 〉 0.05）. While they had difference through anti-dizzy training （ P 〈 0.01 ）. Conclusion： Adaptation training seems useless for reducing incidence and severity of MS in hot-humid environment, but anti-dizzy training is useful.
