【摘要】：目的探讨预缺氧复合锻炼对新兵急进高原后体力劳动能力的改善作用。方法 12 0名进藏新兵随机分为 4组 :对照组、单纯缺氧组、单纯运动组和缺氧复合运动组。在进入高原前 ,缺氧复合运动组佩带低氧呼吸器小步快走 10min ,休息 5min后重复进行 ,上、下午各 4次 ,连续 7d ,单纯缺氧组、单纯运动组分别只佩带低氧呼吸器或单纯运动。空运进藏后 ,比较进藏前、后体力劳动能力改变 ,并对急性高原反应症状进行分析。结果使用低氧呼吸器复合小步快走 5min时动脉血氧饱和度可降到 (80 .5± 5 .7) % ,达到预缺氧目的。缺氧复合运动组新兵进藏后PWC170 与入藏前相比无显著差异 (P 0 .0 5 ) ,急性高原反应的发病率为 3.3%。对照组、单纯缺氧组和单纯运动组新兵进藏后PWC170 均显著降低 (P 0 .0 5 )。急性高原反应的发病率分别为13.3%、2 0 .0 %、2 0 .0 %。结论在进入高原前 ,应用低氧呼吸器辅以适当运动 ,可以改善急进高原后的体力劳动能力、并使急性高原反应发病率呈降低趋势。
[Abstract]:Objective To study the effect of pre-hypoxia combined exercise on the ability of new recruits to move into high altitude. Methods 12 new recruits were randomly divided into 4 groups: control group, simple hypoxia group, simple exercise group and hypoxia compound exercise group. Before entering the plateau, the oxygen-deficient composite sports group wore a low-oxygen respirator for 10 minutes, and after the rest for 5 minutes, the exercise group was repeatedly carried out,4 times in the afternoon,7 days after the simple hypoxia group, and the simple exercise group only wore a low-oxygen respirator or a simple motion. After air transportation, the ability of post-storage and post-physical labor was changed, and the symptoms of acute high altitude reaction were analyzed. Results The oxygen saturation of the arterial blood can be reduced to (80.5 to 5.7)% when the low-oxygen respirator is combined with the small step for 5 minutes to achieve the purpose of pre-hypoxia. There was no significant difference between PWC170 and the pre-Tibetan level (P 0.05), and the incidence of acute plateau reaction was 3.3%. The PWC170 in the control group, the pure hypoxia group and the simple exercise group was significantly lower than that of the control group (P 0.05). The incidence of acute altitude reaction was 13.3%, 2.0% and 2.0%, respectively. Conclusion Before entering the plateau, the low-oxygen respirator is used as a supplement for proper exercise, which can improve the physical labor ability after acute altitude, and decrease the incidence of acute plateau reaction.
