Changes in the direction of human metabolism during rapid adaptation to the conditions of the Far North

Abstract

The aim of the study was to evaluate changes in the direction of human metabolism during rapid transition from the conditions of moderate continental summer to the conditions of the Far North. Method. Urine samples obtained from participants of three polar expeditions at the start and at the finish were studied using laser correlation spectroscopy. Results. Averaged laser correlation histograms for healthy individuals at the finish of all three expeditions showed an increase in the contribution of large particles to the light scattering, which in some cases reached a statistical significance. Urine test revealed no abnormalities in the excretory system. The appearance of large particles can be regarded as an adaptive process of strengthening anabolic processes related with the sharp transition from moderately continental summer to polar summer.
