摘要
低压舱模拟急性低氧3000m和日喀则高原3836m条件下,以41名健康成年人为被试对象,经15min健身器运动使血氧饱和度明显增加,运动后3min血氧饱和度仍比对照值有显著意义的增加。结果提示:在低氧条件下进行健身运动确有提高血氧饱和度的功效,是克服急性低氧反应的一种有效措施。本文对此类健身器运动后增加血氧饱和度的可能性进行了分析。
The study was carried out among 41 healthy subjects born in Shanghai (Sea level). They were divided into two groups. Group one (10 subjects) was studied at sea level in a hypobaric chamber(3000m). Group two (31 subjects) was studied in high altitude plateau (Xigatse at 3836m). Arterial oxygen saturation (SaO 2), Heart Rate (HR),blood pressure (BP) and myocardial oxygen uptake (MVO 2) were measured noninvasively with Nelleor N-200 pulse Oxymeter and HEM 812F Digital Automatic Blood Pressure Monitor. SaO 2 increased significantly (from 87.7±1.7% to 95.3±1.0% P<0.01 and from 86.4±1.0% to 91.8±0.6%, P<0.05, respectively) by healthy exerciser through 15 min in both groups. After 3 min exercise SaO 2 was still significantly higher than before exercise. Then HR, BP and MVO 2 have not change significantly. The study results suggested that this kind of exerciser may help increasing the SaO 2 and thus could be used to prevent and treat acute hypoxic response to some extent.
