The paper reports the data of comparative study of the cardiorespiratory function in healthy males (19-22 year old) from the countries in Asia, Africa, and Latin America lying within the tropic climatic-geographical zone during acute adaptation to the nature and the climate of the middle zone of Russia. The distinctions in respiration, circulation and gas exchange functions in the natives of different climatic-geographical zones were found as during comparative rest so under the combined effects of hypoxia and hypercapnia induced by the rebreathing test and ascribed to the environmental-genetic constitutional properties of the body and the chronobiological characteristics of the place of abode. Reactivity to the combined effects of hypoxia and hypercapnia in different groups is predominantly a function of unequal contributions of hemodynamics and pulmonary ventilation. A relatively low effectiveness of the cardiorespiratory system in representatives of the South-East Asia during acute adaptation was established. These results demonstrate the benefits of the hypoxic-hypercapnic test for determining functional potentials of the cardiorespiratory system in the context of adaptation to a new environment.
该论文报道了来自亚洲、非洲和拉丁美洲热带气候地理区域国家的健康男性（19 - 22岁）在急性适应俄罗斯中部地区的自然环境和气候过程中，心肺功能对比研究的数据。在不同气候地理区域的当地人中，无论是在比较休息状态时，还是在重复呼吸试验诱发的低氧和高碳酸血症联合作用下，呼吸、循环和气体交换功能都存在差异，这归因于身体的环境 - 遗传体质特性和居住地的生物钟学特征。不同组对低氧和高碳酸血症联合作用的反应性主要是血液动力学和肺通气不同贡献的函数。在急性适应过程中，东南亚代表人群的心肺系统有效性相对较低。这些结果证明了低氧 - 高碳酸血症试验在确定适应新环境背景下心肺系统功能潜力方面的益处。
