Metabolic indices were studied in an expedition team consisting of Soviet and U.S. Caucasian and indigenous members. Lipid metabolism was substantially changed during this extended ski expedition, with similar trends among all participants. The most pronounced changes occurred at the beginning of the expedition with a simultaneous change in the lipid protein concentration in very low density lipoprotein (VLDL) and low density lipoprotein (LDL) cholesterol, demonstrating an activation of lipid metabolism. The HDL cholesterol level had the highest level at the third stage of the expedition. Indigenous members showed a relatively greater increase in high density lipoprotein cholesterol (HDL) compared to the Caucasians, suggesting innate differences in adaptability to cold and exertion.
对一支由苏联和美国的高加索人及原住民成员组成的探险队的代谢指标进行了研究。在这次漫长的滑雪探险期间，脂质代谢发生了显著变化，所有参与者都呈现出相似的趋势。最明显的变化发生在探险开始时，极低密度脂蛋白（VLDL）和低密度脂蛋白（LDL）胆固醇中的脂蛋白浓度同时发生变化，表明脂质代谢被激活。高密度脂蛋白胆固醇水平在探险的第三阶段达到最高。与高加索人相比，原住民成员的高密度脂蛋白胆固醇（HDL）升高幅度相对更大，这表明在对寒冷和体力消耗的适应性方面存在先天差异。
