本文对低氧适应锻炼方案进行了初步设计,并观察该方案在提高机体缺氧耐力方面的作用。锻炼组55人在海拔2800m高度上进行长跑锻炼,每天2.5h,持续17天。之后,该适应锻炼组与在此同一高度上不进行锻炼的单纯适应组56人同时到达海拔4900m高度,进行急性高山反应症状学调查和血气分析,脑血流和心血管功能检查。结果表明,适应锻炼组中没有发生急性高山反应和轻度反应的分别为64.6和32.5%;单纯适应组分别为27.4和48.8%,而且该组出现了中度和重度反应者(P<0.05)。同时,适应锻炼组的生理功能也有所改善。可见,本文所设计的适应锻炼方案,在提高机体对缺氧的耐力和预防急性高山反应方面,效果明显。
In this paper, a preliminary design of hypoxic adaptation exercise program was conducted and the effect of this program on improving the hypoxic endurance of the body was observed. Exercise group of 55 people at 2800m above sea level for long-distance exercise, 2.5h daily for 17 days. After that, 56 people in the adaptive exercise group and the simple adaptation group who did not exercise at the same altitude reached the altitude of 4900m at the same time for acute alpine symptomatic investigation and blood gas analysis, cerebral blood flow and cardiovascular function tests. The results showed that there were 64.6% and 32.5% respectively of acute alpine reaction and mild reaction in the acclimation exercise group, 27.4% and 48.8% in the simple acclimation group, and there were moderate and severe responders (P <0.05) . At the same time, the physiological functions of the exercise group also improved. Can be seen that this article designed to adapt to exercise programs to improve the body’s resistance to hypoxia and prevent acute alpine reactions, the effect is obvious.
