PetrSU scientists summarize the results of their scientific research in the field of spatial physiology.
Since 2015, the Department of Human and Animal Physiology, Pathophysiology, Histology of the PetrSU Medical Institute has been carrying out research to study the effect of simulated weightlessness on the ground on the body of an elderly person with Parkinson’s disease. .
This year there were 3 articles in the journal “Human Physiology” and 2 articles in the journal “Frontiers in Physiology”, 3 articles are under review or ready to be submitted.
It must be said that judging by the read and download statistics, the interest in these articles is enormous, especially in Germany, Belgium, the USA and the PRC. We attribute this to the recent flights to suborbital space of two private spacecraft – Jeff Bazos on Blue Origin and Richard Branson on VVS Unit with a crew of elderly tourists.
As a perspective, we have reported in our articles that soon the flights of elderly people in suborbital space will be a reality, but there is little research on the physiology of an elderly person in space, and on an affected person. of neurodegenerative diseases, there is not all. Our studies have shown that a short-term state of weightlessness, with careful selection of candidates, has no negative consequences for the cardiovascular system, even for a patient with parkinsonism. In some ways, this flight is even useful. In fact, through our work, we have filled an important gap in the spatial physiology and rationale for space tourism. The recent arrival on the ISS of a team to shoot the first space film only confirms this trend.

In April of this year the Human in Space conference was held, in May the traditional conference of the International Society of Gravitational Physiology (ISGP’42), dedicated to the 60th anniversary of the first manned flight in space. The members of this organization are professors. The “Road to Space” conference has just been held.
The last event should be noted, since this conference is being held within the framework of World Space Week (4-10 October) dedicated this year to women in astronautics, as well as within the framework of the Space Science Days organized under the auspices of Roscosmos in honor of the launch of the first terrestrial satellite and the Russian Year of Science and Technology. In general, there are a lot of important events.
We have spoken at all the conferences with the scientific results of many years of research, talking about the training prospects in the field of space medicine. In the future, the department will continue to cooperate with the Moscow Center for Medicine and Aerospace Technology on the use of virtual reality methods to assess the reaction rate in weightlessness, the introduction of new physiological research methods such as evaluation of cerebral circulation during immersion, phenomenon of muscle tone under model weightlessness conditions, investigation of the interception reactions of a moving target. We will also continue our educational and educational mission, because it is more interesting to study with space.
A simple example. Physiology textbooks pay very little attention to the fact that all of our physiological functions (and their pathophysiological changes) occur under conditions of gravity and are primarily antigravitational. This applies to movement, orientation in space, habitual standing and maintaining posture, movement of blood, especially venous blood, the ratio of ventilation and perfusion in the lungs. In general, this makes you be a physicist, biophysicist, mechanic and more and more often consult the textbook of elementary physics.
The project to immerse patients with parkinsonism in a state of zero gravity has become a real catalyst for cooperation, in which more and more colleagues from various PetrSU institutes are involved,
