| [摘要]目的通过在高温高湿环境下对相关人员进行系统训练,明确高温高湿环境训练与晕动病等级变化情况的关联。方法挑选我校年龄在18~23岁的男性学员60人作为受试者,均体检合格并经《军人体能标准》测试达标; 其中30人为实验组,另30人构成对照组; 实验组在35~39℃高温与60%~85%湿度的高温高湿环境下进行相同项目与相近强度的晕动病转椅吊转习服训练,两组在实验前后各自进行两次晕动病测试,均以科里奥利(Coriolis)加速度转椅实验诱发晕动病,以格瑞比尔(Graybiel)评分法评定晕动病程度。结果根据等级程度不同,设N为无不适,Ⅰ为轻度不适,ⅡB分为中度不适B级,ⅡA为中度不适A级,Ⅲ分为重度不适,F为严重不适。实验组总人数29人(1人退出),训练前晕动病等级如下:N 2人,Ⅰ0人,ⅡB 0人,ⅡA 0人,Ⅲ21人,F 6人; 训练后晕动病等级如下:N 0人,Ⅰ3人,ⅢB 7人,ⅡA 4人,Ⅲ14人,F1人。对照组30人,训练晕动病等级如下:N 1人,Ⅰ1人,ⅡB 0人,ⅡA 1人,Ⅲ22人,F4人,总人数29人; 实验结束,晕动病等级如下:N 0人,Ⅰ0人,ⅡB 5人,ⅡA 3人,Ⅲ16人,F 5人。通过高温高湿环境下系统的训练,实验组受试者晕动病等级较对照组下降,实验组平均晕动病等级较对照组改善，组间差异有统计学意义(P<0.05)。结论湿热环境下的训练可以改善同样条件下晕动病的发病情况，降低晕动病发病强度。 |

| Abstract: |
| [Abstract]ObjectiveTo study the effect of training in the humid heat environment on motion sickness by systemically training volunteers in the humid head environment. MethodsSixty volunteers, aged 18-23 years old, were selected from 567 male college students. All the subjects passed health examination and the Soldier Physical Ability Standard test of Chinese People’s Libration Army. They were equally divided into an experimental group and a control group. The experimental group received adaptation training with motion sickness device in humid heat environment (35-39℃, 60%-85% humidity). Motion sickness tests were done in both groups before and after training. The Criolis acceleration rotational chair was used to induce the motion sickness and Graybiel scale was used to evaluate the degree of motion sickness. MethodsThe degrees of discomfort were defined as following: N, no; Ⅰ, slight; ⅡB, moderate B; ⅡA, moderate A; Ⅲ, severe; and F, serious. The motion sickness degree distribution in the experiment group was (1 dropout due to sickness) N, 2; Ⅰ, 0; ⅡB, 0; ⅡA, 0; Ⅲ, 21; F, 6 before the training; and N, 0; Ⅰ, 3; ⅡB, 7; ⅡA, 4; Ⅲ, 14; F, 1 after the training. The distribution of the control group was N, 1; Ⅰ, 1; ⅡB, 0; ⅡA, 1; Ⅲ, 22; F, 4 before the training; and N, 0; Ⅰ, 0; ⅡB, 5; ⅡA, 3; Ⅲ, 16, F, 5 after the training. MethodsTraining in humid heat enviroment can achieve a great decrease in motion sickness degree, with the average motion sickness degree in the experiment group greatly improved compared with that in the control group. |
