[Seasonal dynamics of external respiration and gas exchange in the population of northeast Russia]

Abstract

In conjunction with the MARS-500, a monthly monitoring of several morphofunctional parameters was performed in 19 Caucasoid volunteers born in the Magadan region over the period of 18 months. The standard procedures were used for somatometric examination and evaluation of the respiratory and cardiovascular functions. The greatest straining of these body systems was stated in wintertime. However, during summer both systolic and diastolic pressure was also high when compared with people living in the center and north of European Russia, which may infer a significant effect of seasonal variations in the Magadan environment and climate on human organism throughout the year.
