The influence of geomagnetic and environmental factors on the changes in autonomic regulation (based on a satellite experiment Mars-500). Chernikova A., Zenchenko T., Baevsky R. Institute of bio-medical problems RAS, Moscow, Russia Slide 2 The analysis of the organism condition in cosmonauts during and after a prolonged staying in microgravity on the OS MIR" and the ISS did not reveal any abnormalities that prevent the gradual increase in the duration of manned space flight. The analysis of the organism condition in cosmonauts during and after a prolonged staying in microgravity on the OS MIR" and the ISS did not reveal any abnormalities that prevent the gradual increase in the duration of manned space flight. An important precondition for the success of the interplanetary missions is the ability of the human body to adapt to conditions of prolonged space flight. An important precondition for the success of the interplanetary missions is the ability of the human body to adapt to conditions of prolonged space flight. Slide 3 At the same time individual characteristics of an organism (a type of regulation, age) and environmental conditions (environmental and social conditions, the type of impact, seasonal changes) play an important role. At the same time individual characteristics of an organism (a type of regulation, age) and environmental conditions (environmental and social conditions, the type of impact, seasonal changes) play an important role. The scientific justification of this working hypothesis in reference to problems of Mars mission medical support together with the development of theoretical positions on functional reserves of human would be an important contribution to the preparation of manned flights to Mars. Slide 4 Mars-500 project has being conducted by the State scientific center of the Russian Federation Institute for Bio-medical Problems of RAS under the aegis of Roscosmos, ESA and Russian Academy of Sciences. It included a series of experiments simulating these or those aspects of an interplanetary manned flight. The main part was a series of experiments on long-term isolation of the crew in conditions of the specially built ground-based experiment facility.

Work and rest schedule of the crew is the same as in orbital flights (7-day week with two free days). Work and rest schedule of the crew is the same as in orbital flights (7-day week with two free days). Rations for crew members were identical to those used on the International Space Station. Rations for crew members were identical to those used on the International Space Station. The crew was in an artificial environment at normal atmospheric pressure. The crew was in an artificial environment at normal atmospheric pressure. Slide 6 The specificity of the project "Mars- 500" from positions the theory of adaptation 1) The long-term adaptation processes lead to some restructuring of the regulatory mechanisms and the establishment of new functional relationships in the body. This can lead to increased spending of functional reserves and substantially increase the risk of disease. 2) experimental factors, affecting the body, gradually become less important due to the "addiction" to them (the factor of acclimatization). Slide 7 To solve the problem - studying the characteristics of adaptation processes during prolonged stay in the crew of stress conditions in the model of the spaceship, we deemed it necessary to to conduct a parallel experiment to compare the reactions of the organism in the long-term isolation from the reactions of similar groups of people living under natural conditions. Slide 8 For the scientific analysis of changes in health status of the "Martian" crew control experiments in which similar groups of people would be in the wild under the influence of various environmental factors: climatic and geographical, industrial, social and other. In this regard, control satellite studies, which were held simultaneously in several groups of volunteers, were organized. The reference groups were formed in 11 regions including 6 groups in Russia, one in Germany, one in Czech, one in Belarus, one in USA and one in Canada. The reference groups consisted of 10 to 15 essentially healthy males in the same age range.

This hypothesis can be stated as follows: long-term tension of regulatory systems leads to a decrease in functional reserves, reduced its adaptive capacity and as a result increased risk of disease.

A new methodological approach, developed in space medicine for assessing the risk of disease according to the HRV analysis [Baevsky, Chernikova, 2002, 2010], was used while assessing the results of studies. Adaptation level is measured here by the parameters of the functional reserves (FR) and the stress degree (SD) Slide 16 The space of functional states The measure of quantifying the health risks is the probability of prenosological and premorbid states, which differ from normal states by significant shifts in autonomic balance.
