高原驻训官兵运动前后一般生理指标变化研究

Physiological index changes of officers and soldiers after training in the plateau

目的:观察高海拔地区运动对驻训人员一般生理指标的影响。方法:选择由海拔2 260m进入海拔4 200m高原驻训1个月的部队健康男性73名,分为运动组和对照组,其中运动组39名,年龄18~36岁,平均(24.56±5.43)岁;对照组34名,年龄19~38岁,平均(26.06±4.70)岁。全体受试者晨起空腹检测脉搏、血氧饱和度(SaO_2)、血压,随后运动组进行2km慢跑(15~20min内完成),结束5min时再次检测上述指标。此后,运动组每日进行2km慢跑,对照组不参与体力活动,只进行日常工作。2周后全体受试者晨起空腹检测上述指标。结果:运动前两组血压、脉搏、SaO_2无统计学差异(P>0.05);对照组试验前后各指标无统计学差异(P>0.05);运动组第1天运动后SaO_2、脉搏明显提高,差异极显著(P<0.01),收缩压降低,但未达到统计学标准(P>0.05),舒张压无明显变化。运动组2周后脉搏、血压明显降低,SaO_2明显提高(P<0.01),与对照组比较也有明显差异(P<0.01或P<0.05)。结论:高原适当运动可改善SaO_2、血压,可能有利于高原适应。

Objective：To observe effect of exercise at plateau on people’s physiological index.Methods：Seventy-three healthy male soldiers entered altitude from 2 260 mto 4 200 mfor one month were divided into exercise group and control group,39 cases in exercise group,18-36（24.56±5.43）years old,34 cases in control group,19-38（26.06±4.70）years old.Pulse,oxygen saturation（SaO2）and blood pressure were collected in all subjects before breakfast.Subjects in exercise group jogged 2kilometers every morning for two weeks,and accomplished the exercise in 15 to 20 minutes,repeated those tests within 5 minutes after first jogging.Subjects in control group proceeded routine work without physical activity in the two weeks.Results：There were no statistic difference in blood pressure,pulse and SaO2 between two groups before exercise（P〉0.05）,and also in control group before and after two weeks（P〉0.05）.After first jogging,SaO2 and pulse increased significantly（P 〈0.01）,systolic pressure decreased without statistical difference（P 〉0.05）,there was no significant difference in diastolic pressure.Pulse and blood pressure decreased,SaO2 increased obviously（P〈0.01）in exercise group two weeks later.There were significant differences between two groups（P 〈0.01 or P〈0.05）.Conclusion：Proper exercise at plateu can improve SaO2 and blood pressure,may profit for plateau acclimatization.
