目的:观察富氧联合运动训练治疗急性高原反应(AMS)的效果。方法:将AMS 28例随机分成富氧联合运动训练组(观察组)和对照组各14例。对照组处于自然低氧环境中,不进行运动训练;观察组分别在26.0%、24.5%、23.0%和21.5%的富氧条件下,进行运动训练各1天;观察比较两组训练期间和训练结束后第1天的收缩压(SBP)、舒张压(DBP)、心率(HR)、血氧饱和度(SO2)水平和AMS评分。结果:训练第1天,观察组HR非常显著低于对照组(P<0.01);训练期间及训练结束后第1天SBP和DBP两组间差异不显著(P>0.05);观察组SO2水平非常显著高于对照组(P<0.01);观察组训练期间和训练后第1天AMS评分非常显著低于对照组(P<0.01)。结论:富氧联合运动训练可有效减轻AMS症状,缩短习服时间。
Objective: To observe the effect of oxygen-enriched combined exercise training on acute altitude sickness (AMS). Methods: 28 cases of AMS were randomly divided into two groups: the oxygen-enriched combined exercise training group (observation group) and the control group (14 cases). The control group was in a natural hypoxia environment without exercise training. The observation group was exercised for one day at 26.0%, 24.5%, 23.0% and 21.5% oxygen-enriched conditions respectively. The observation and comparison of the two groups during training and training Systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), oxygen saturation (SO2) level and AMS score on the first post-treatment day. Results: On the first day of training, HR in the observation group was significantly lower than that in the control group (P <0.01). There was no significant difference in SBP and DBP between the training group and the first day after the training (P> 0.05) (P <0.01). The AMS score of the observation group during training and on the first day after training was significantly lower than that of the control group (P <0.01). Conclusion: Oxygen-enriched combined exercise training can effectively alleviate the symptoms of AMS and shorten the time of attending.
