本研究的目的是阐明mtDNA单倍型群和季节变化之间的相互作用，有助于冷适应。共有15名受试者（7名单倍型D受试者和8名单倍型非D受试者）。在夏季和冬季，受试者被置于环境温度在30分钟内从27 °C降至10 °C的环境中。之后，他们被暴露在寒冷中60分钟。在夏季，非D单倍型组的直肠温度下降幅度和耗氧量增加幅度均小于D单倍型组，耐寒性高于D单倍型组。在冬季，直肠温度和耗氧量没有显著差异，但呼吸交换率在单倍型D组中降低。本研究的结果表明，单倍型D的主题是一组，改变能量代谢更多，似乎有一个关系之间的差异，冷适应性和mtDNA多态性的人口。此外，由于季节性冷习服的补充，夏季冷适应性的群体差异可能在冬季减少。
The purpose of this study was to elucidate the interaction between mtDNA haplogroup and seasonal variation that contributes to cold adaptation. There were 15 subjects (seven haplotype D subjects and eight haplotype non-D subjects). In summer and winter, the subjects were placed in an environment where the ambient temperature dropped from 27 °C to 10 °C in 30 minutes. After that, they were exposed to cold for 60 minutes. In summer, the decrease in rectal temperature and increase in oxygen consumption was smaller and cold tolerance was higher in the haplotype non-D group than in the haplotype D group. In winter, no significant differences were seen in rectal temperature or oxygen consumption, but the respiratory exchange ratio decreased in the haplotype D group. The results of the present study suggest that haplogroup D subjects are a group that changes energy metabolism more, and there appears to be a relationship between differences in cold adaptability and mtDNA polymorphism within the population. Moreover, group differences in cold adaptability seen in summer may decrease in winter due to supplementation by seasonal cold acclimatization.
