“…Research on the effect of weight gain was carried out with the participation of many station crews and all the studies were complex (the functions of all systems were tested before and after the expedition) and throughout the stay, the cycles were measured quarterly, and anthropometric indicators were recorded monthly (weight, height, and percentage body fat), vital capacity, electrocardiography, clinical blood tests, daily body temperature, blood pressure, heart rate, psychological examination, as well as daily monitoring of autonomic regulation indicators and sleep quality test. The results indicated one-way changes in body weight and the examination of functions with a clear tendency towards the development of maladaptive disorders and symptoms of latent hypoxia [ 10 , 11 , 12 , 13 , 14 ]. Therefore, in order to thoroughly understand latent hypoxia and the mechanisms of association with increased overweigh, targeted studies were conducted involving the average (based on screening results) nominate with the highest weight gain.…”
