construction of buildings, which requires a certain set of building materials,

The second stage of life begins when the body is plastically built and no longer needs the amount of "building materials" that is required during the period of growth,

Given the characteristics of these two periods of lichen, it is necessary to take a different approach to the regimen of physical education, the volume of loads and, of course, nutrition.

For people of all ages, from newborns to the elderly, physical activity and movement are just as important as good nutrition. The child receives a unique set of genes from his parents, which to some extent determines the level of health. But. Regardless of the information programmed in the chromosomes, which ensures the “planned” development of the organism, it is necessary to stimulate the intensity of energy exchange processes in cells in a targeted manner. In any organism, especially a growing one, all systems are surprisingly subtly interconnected. This is due to the continuous development of the structural networks of the nervous system, which controls and imprints all the ongoing changes in the internal and external environment. Since the tension of one of the physiological systems immediately causes a response increase in the activity of the whole organism, including the hormonal system, it can be said that the organism functions on the principle of a self-balancing system (naturally, we do not touch on various pathologies - imbalances in the body related to medical medicine).

As a rule, a preschool child who is physically active, moves a lot, performs movements that are different in duration, dynamics and coordination, more accurately orients in space, quickly masters speech skills and the basic rules of behavior. It is important not only to help a child learn about the world around him, but also to expand the motor capabilities of a small person.

At school age, when the regime of intense mental work becomes constant, high physical activity is more necessary than ever. The role of movement is not limited to maintaining health - physical activity helps mental activity.

According to the law of psychophysical harmony, which does not allow deviations either in the direction of the predominant - "training" of the intellect, or in the direction of being carried away "and physical activity to the detriment of mental development, it is necessary to balance these two mutually complementary, mutually compensating spheres of human activity,

When switching the work of the intellect from solving abstract problems to motor skills, that is, motor activity in which other parts of the brain are involved, the processes of its energy supply are activated. As a result, hard-working logical centers that need to be “recharged” with energy are restored. In addition, the optimal volume of physical activity contributes to the active rest of the intellectual centers of the brain.

Speaking about the need for high physical activity in childhood and adolescence, one should not forget about one warning. It is necessary to choose classes that are available, which will benefit and will not cause undesirable consequences. Is it necessary to prove what harm will be caused to a growing and developing organism by a reckless passion for energy-intensive sports related to endurance work, when the vital resources intended for the formation of all organs and systems of the body will be diverted to ensure intensive energy consumption?

Especially you need to be careful at the age of 15-1eight, during the period of intensive physiological) development, puberty and final formation of the endocrine system.

Of course, these warnings do not mean giving up intense physical activity, but they remind you of the additional requirements for diet, rest and recovery.

In the second stage of life, after the cessation of growth and the completion of the development of the organism, the plastic function of metabolism is sharply reduced - now it is reduced only to the replacement of destroyed cells. During this period, it is important to maintain a state of balance in all body systems, to counteract the inevitable slowing down of the activity of the endocrine system, which produces hormones that control almost all biochemical processes.

During the period of maturity, the so-called cholesterol brake is formed in the body of men, and by the age of 50, the amount of cholesterol in the blood approximately triples. It blocks cells and prevents the absorption of glucose - the main energy carrier, and glucose is converted into fat. In women, this process also intensifies from about 50 years of age.

Without any doubt, the only way to maintain all body systems at a healthy physiological level, delaying the processes of aging and the onset of senile infirmity - first physical, and then intellectual, is the active management of energy through muscle activity. For this, of course, one must have some basic knowledge in the field of physiology and bases of physical culture.

All forms of physical activity have one feature. It turns out that it is not the total amount of muscle energy expended that is important, but the degree of tension in muscle structures - one of the indicators of the activity of the central nervous system. The complexity of muscle actions is also very important, reflecting the work, first of all, of the logical centers of the brain, which control the actions of muscles through motor neurons. Such a relationship of intellectual and physical stress can ensure the normal functioning of the body, the development of mental abilities, physical and mental health.

In the process of long-term intense mental work (as a rule, it is performed while sitting), energy exchange in the muscular system proceeds at a minimum level. Blood flow slows down, breathing becomes shallow. A decrease in the amount of carbon dioxide in the blood leads to a decrease in the efficiency of the transport function of the circulatory system. As a result, less oxygen is delivered to actively working brain cells and carbon dioxide accumulates in them. Intellectual productivity declines.

Such a mismatch between energy supply and the work of the brain is explained by a violation of the processes of tension in the psyche and the muscular system. Under the conditions of a sharp decrease in the physical activity of a modern person and an ever-increasing flow of information, the disproportion in the load on the brain and muscular system increases. Therefore, it is necessary to balance the tension of the psyche and the muscular system.

When we perform muscular work that is difficult to coordinate, in the brain, according to the feedback principle, all signals coming from nerve endings are recorded. And the wider and richer the range of forward and reverse signals, the more actively the brain works.

Regular and properly organized physical education classes help to remove psychological barriers in solving a wide variety of tasks, training a person’s ability to mobilize physical and intellectual potential at the level of an “energy explosion”. A high degree of physical activity is adequate to a high level of development of volitional qualities: sport teaches not to be afraid of tension and stress. After all, action is the main manifestation of life.

Of course, everyone has the right to choose one or another type of physical education. I am convinced that it is athleticism, or athletic gymnastics, that has the most beneficial effect on the muscular system and is the basis of psychophysical training. Almost all sports, even chess, are inconceivable without versatile muscle training. Our leading chess players - world champion G. Kasparov and his constant rival ex-champion A. Karpov are actively engaged, especially when preparing for important matches, in tennis, swimming, running, playing football in order to gain psychological stability and functional endurance.

Athletic gymnastics allows you to maintain a high level of psychophysical functions, which are an indicator of health. In our time of automation and computerization, the consequences of a sedentary lifestyle are becoming more and more acute, athletic gymnastics can be be considered both as an independent type of physical culture, and as an effective aid for the development of special speed-strength qualities, as well as strength endurance.

Regular athletic gymnastics (at least once a week), aimed not only at increasing the energy exchange of the body, but also at achieving a healing effect (maintaining good muscle tone, the musculoskeletal system and the cardiovascular system), will allow you to maintain physical and intellectual activity for many years, pushing back the onset of old age and its accompanying diseases.

Athletic gymnastics will help to avoid the “fashionable” disease in our time - osteochondrosis of the spine, which affects a person most often in the prime of life - before and after 30 years, as well as joint disease - arthritis. Prevention of these diseases is primarily physical activity that prevents metabolic disorders.

A special set of exercises, consisting of physical loading of the muscular system, helps to cure one of the most common types of osteochondrosis of the spine, lumbosacral sciatica, which affects tens of millions of people in our country alone. These exercises, designed taking into account the laws of biomechanics, optimally combine the load on muscles, joints and spine.

Athletic gymnastics in adulthood (the second period of life) is the only way to “burn” extra, unused calories that turn into fat ballast, which over the years more and more inevitably destroys health.

Without muscle training, it is impossible to train the heart muscle and breathing. Following the work of the muscles, all life support processes are activated; metabolic reactions, blood flow, gas exchange, the supply of hormones to the blood, etc. Official medicine has already recognized that doctors cannot cope with the negative consequences of civilization and the task of healing with the help of affordable physical exercises is now before everyone.
