本文通过高原现场观察,对利氧灵提高人体高原劳动能力的效果进行了评价。20名受试者以配对实验设计分为实验组(利氧灵组)和对照组,每组10人。先在平原测量无氧阈(AT_(GE)),PWC_(170)和定量负荷运动心率(HR)。而后,乘飞机到达海拔4370m高原,重复上述指标的测量。结果表明,在该高度上停留一周时间里,两组的AT_(GE)、PWC_(170)明显低于平原对照值,HR明显高于平原对照值。但在同一时间里,实验组的上述指标明显好于对照组,如第5天,实验组的TI_(GE)、PWC_(170)和HR分别为529.2kg·m/min,1216.4kg·m/min和160b/min;对照组分别为362.6kg·m/min(P<0.05),1016.1kg·m/min(P<0.05)和170b/min(P<0.05)。可见,利氧灵对提高人体高原劳动能力有一定作用。
In this paper, through on-site observation in the plateau, the effects of LXL on improving the work ability of the human body on the plateau were evaluated. Twenty subjects were divided into the experimental group (liniment group) and the control group in a paired experimental design, with 10 in each group. Anaerobic thresholds (AT_ (GE)), PWC_ (170), and heart rate (HR) were measured first in plain. Then, by plane to reach an altitude of 4370m plateau, repeat the measurement of the above indicators. The results showed that the AT GE and PWC 170 of the two groups were significantly lower than that of the plain control and HR significantly higher than that of the plain control at the height of one week. However, at the same time, the above indexes of the experimental group were obviously better than those of the control group. On the fifth day, the TI_ (GE), PWC_ (170) and HR of the experimental group were 529.2kg · m / min and 1216.4kg · m / min and 160b / min respectively. The control group was 362.6kg · m / min (P <0.05), 1016.1kg · m / min (P <0.05) and 170b / min respectively. Visible, Ling Li Ling to improve the body’s ability to work in highlands have a certain effect.
