目的：探讨3200 m高原适度运动对急性高原病（AMS）发病率的影响。方法91名健康、久居平原受试者从平原（345 m）乘火车于48 h内到达3200 m高原，停留2夜后行步行5 km运动。运动前后行AMS路易斯湖评分（LLS）、血压、血氧饱和度（SpO2）检测。结果7名受试者因数据不全被排除分析。运动前后 AMS 发病率分别为20．24％（n＝17/84）及11．90％（n＝10/84），差异无统计学意义（P＞0．05）。运动后心率从（73．83±9．96）次/分升至（84．31±12．55）次/分（P＜0．05），收缩压从（128．86±13．93）mm Hg降低至（124．48±13．13）mm Hg （P＜0．05），SpO2从（92．80±2．25）％降低至（89．94±2．45）％（P＜0．05）。运动后头痛症状改善（P＜0．05）。运动前后吸烟史与LLS成绩均呈负相关（P＜0．05）。LLS评分与SpO2无明显相关性。结论在3200 m步行5 km能改善头痛症状，并有降低AMS发病率的趋势。

Objective To evaluate the effect of moderate activities at moderate high altitude on acute mountain sickness (AMS) incidence .Methods Ninety-one healthy sea level residents traveled from sea level (345 m) to high altitude city (3200 m) ,by train within 48-hour .They walked 5 kilometers after 2-night stayed ,Lake Louis Score (LLS) Questionnaires ,blood pressure(BP) and oxygen saturation (SpO2 ) was administered before and after walking .Results Seven subjects were excluded because of incomplete data .The incidence of AMS before and after exercise was 20 .24% (n=17/84) and 11 .90% (n=10/84) respectively(P>0 .05) .Af-ter a 5 kilometer walking ,the heart rate increased from (73 .83 ± 9 .96)bpm to(84 .31 ± 12 .55)bpm (P<0 .05) ,Systolic BP and SpO2 level decreased from(128 .86 ± 13 .93)mm Hg to (124 .48 ± 13 .13)mm Hg ,(92 .80 ± 2 .25)% to (89 .94 ± 2 .45)% (P<0 .05) .Headache symptom improved after walking (P<0 .05) .Smoking was negative correlate with LLS score before and after ex-ercise(P<0 .05) .There is no relation between SpO2 and LLS scores .Conclusion Walking five kilometers at 3200 m improve head-ache symptom and tend to decrease AMS .
