Using indirect calorimetry, we examined 1632 young males aged 17 to 21 years, belonging to the Europeoid (Caucasian) race and residing permanently in the city of Magadan. Depending on the duration of adaptation to the conditions of the Northeast of Russia, all male subjects were divided into 3 groups of generation 1, 2 and 3 descendants and a group of newcomers (migrants or adaptants) residing in the Magadan Region for a short period of time (generation 0). It was established that in the lineage from generations 0 to 3 there occurred an optimization of the ventilatory characteristics of the external respiration apparatus aimed at cutting respiratory heat losses during adaptation to extreme conditions of the Northeast, i.e. a decrease in the tidal volume, tidal minute volume, and respiratory rate. Relevant rearrangements of the ventilatory pattern in subjects with a longer duration of residence under the same extreme conditions are paralleled by an improvement of oxygen transport and more efficient use of each respiratory cycle.

来自不同世代欧洲移民和适应者的马加丹地区年轻男性的气体分析参数动态

我们使用间接量热法检查了 1632 名年龄在 17 至 21 岁之间的年轻男性，这些男性属于欧洲人种（高加索人）并永久居住在马加丹市。根据适应俄罗斯东北部条件的持续时间，所有男性受试者被分为 1、2 和 3 代后代 3 组，以及在马加丹地区短期居住的新移民（移民或适应者）时间（第 0 代）。已经确定，在第 0 代到第 3 代的谱系中，外部呼吸装置的通气特性发生了优化，旨在减少在适应东北极端条件期间的呼吸热量损失，即潮气量、潮汐分钟数的减少量和呼吸频率。
