METHODS OF PHYSIOLOGICAL RESEARCH.
Physiology is an experimental science. Knowledge about the functions and mechanisms of the body’s activity is based on experiments conducted on animals, observations in the clinic, and examinations of healthy people under various experimental conditions. At the same time, in relation to a healthy person, methods are required that are not associated with damage to his tissues and penetration into the body - the so-called non-invasive methods.
IN general form physiology uses three methodological research methods: observation or the “black box” method, acute experience and chronic experiment.

Classical research methods were methods of removal and methods of irritation of individual parts or entire organs, mainly used in experiments on animals or during operations in the clinic. They gave an approximate idea of ​​the functions of removed or irritated organs and tissues of the body. In this regard, a progressive method for studying the whole organism was the method of conditioned reflexes developed by I. P. Pavlov.

IN modern conditions The most common are electrophysiological methods that allow recording electrical processes without changing the current activity of the organs being studied and without damaging the integumentary tissues - for example, electrocardiography, electromyography, electroencephalography (registration of electrical activity of the heart, muscles and brain). The development of radio telemetry makes it possible to transmit these received records over considerable distances, and computer technologies and special programs- provide subtle analysis of physiological data. The use of infrared photography (thermal imaging) allows us to identify the hottest or coldest areas of the body observed at rest or as a result of activity. With the help of so-called computed tomography, without opening the brain, you can see its morphofunctional changes at different depths. New data on the functioning of the brain and individual parts of the body are provided by the study of magnetic oscillations.

Preface

Human physiology is theoretical basis a number of practical disciplines (medicine, psychology, pedagogy, biomechanics, biochemistry, etc.). Without understanding the normal course of physiological processes and the constants that characterize them, various specialists cannot correctly assess the functional state of the human body and its performance in various operating conditions. Knowledge of the physiological mechanisms of regulation of various body functions is important in understanding the course of recovery processes during and after intense muscular labor.

Revealing the basic mechanisms that ensure the existence of a whole organism and its interaction with environment, physiology makes it possible to clarify and study the conditions and nature of changes in the activity of various organs and systems in the process of human ontogenesis. Physiology is the science that carries out systems approach in the study and analysis of diverse intra- and intersystem relationships of complex human body and bringing them together specific functional formations and a unified theoretical picture.

It is important to emphasize that domestic researchers play a significant role in the development of modern scientific physiological concepts. Knowledge of the history of any science is a necessary prerequisite for a correct understanding of the place, role and significance of the discipline in the content of the socio-political status of society, its influence on this science, as well as the influence of science and its representatives on the development of society. Therefore, consideration of the historical path of development of individual branches of physiology, mention of its most prominent representatives and analysis of the natural science base on which the basic concepts and ideas of this discipline were formed make it possible to evaluate current state subject and determine its further promising directions.

Physiological science in Russia in the 18th–19th centuries is represented by a galaxy of brilliant scientists - I. M. Sechenov, F. V. Ovsyannikov, A. Ya. Danilevsky, A. F. Samoilov, I. R. Tarkhanov, N. E. Vvedensky and etc. But only I.M. Sechenov and I.P. Pavlov deserve the credit for creating new directions not only in Russian, but also in world physiology.

Physiology as an independent discipline began to be taught in 1738 at the Academic (later St. Petersburg) University. Moscow University, founded in 1755, also played a significant role in the development of physiology, where the Department of Physiology was opened within its structure in 1776.

In 1798, the Medical-Surgical (Military Medical) Academy was founded in St. Petersburg, which played an exceptional role in the development of human physiology. The Department of Physiology created under her was successively headed by P. A. Zagorsky, D. M. Vellansky, N. M. Yakubovich, I. M. Sechenov, I. F. Tsion, F. V. Ovsyannikov, I. R. Tarkhanov, I. P. Pavlov, L. A. Orbeli, A. V. Lebedinsky, M.P. Brestkin and other outstanding representatives of physiological science. Behind each named name there are discoveries in physiology that are of global significance.

Physiology was included in the curriculum at physical education universities from the first days of their organization. At the Higher Courses of Physical Education created by P. F. Lesgaft in 1896, a physiology office was immediately opened, the first director of which was Academician I. R. Tarkhanov. In subsequent years, physiology was taught here by N.P. Kravkov, A.A. Walter, P.P. Rostovtsev, V.Ya. Chagovets, A. G. Ginetsinsky, A. A. Ukhtomsky, L. A. Orbeli, I. S. Beritov, A. N. Krestovnikov, G. V. Folbort and others.

The rapid development of physiology and the acceleration of scientific and technological progress in the country led to the emergence in the 30s of the 20th century of a new independent section of human physiology - sports physiology, although individual works devoted to the study of body functions during physical activity were published at the end of the 19th century (I O. Rozanov, S. S. Gruzdev, Yu. V. Blazhevich, P. K. Gorbachev, etc.). It should be emphasized that systematic research and teaching of sports physiology began in our country earlier than abroad, and was more targeted. By the way, we note that only in 1989 the General Assembly of the International Union of Physiological Sciences decided to create a commission under it “Physiology of Sports”, although similar commissions and sections in the system of the USSR Academy of Sciences, the USSR Academy of Medical Sciences, the All-Union Physiological Society named after. I. P. Pavlova of the USSR State Sports Committee have existed in our country since the 1960s.

The theoretical prerequisites for the emergence and development of sports physiology were created by the fundamental works of I. M. Sechenov, I. P. Pavlov, N. E. Vvedensky, A. A. Ukhtomsky, I. S. Beritashvili, K. M. Bykov and others. However, the systematic study of the physiological foundations of physical culture and sports began much later. Particularly great merit in the creation of this section of physiology belongs to L. A. Orbeli and his student A. N. Krestovnikov, and it is inextricably linked with the formation and development of the University of Physical Culture. P.F. Lesgaft and his department of physiology - the first such department among physical education universities in the country and in the world.

After the creation in 1919 of the Department of Physiology at the Institute of Physical Education. P. F. Lesgaft teaching this subject carried out by L. A. Orbeli, A. N. Krestovnikov, V. V. Vasilyeva, A. B. Gandelsman, E. K. Zhukov, N. V. Zimkin, A. S. Mozzhukhin, E. B. Sologub, A. S. Solodkov and others. In 1938, A. N. Krestovnikov published the first “Textbook of Physiology” in our country and in the world for physical education institutes, and in 1939 – the monograph “Physiology of Sports”. An important role in further development The teaching of the discipline was played by three editions of the “Textbook of Human Physiology” edited by N.V. Zimkin (1964, 1970, 1975).
