The effect of physical education and sports on the body

The health of a modern person is inextricably linked with sports and physical education, which can improve the protective functions of the body so that it can withstand the harmful effects of aggressive microorganisms, adverse environmental conditions and other negative environmental factors. This is achieved not only by performing various trainings and exercises in the gym and at home, but also by balanced proper nutrition. This combination allows you to resist the development of many diseases, strengthen the immune system, increase its resistance to various negative effects .

The value of physical activity in modern society

Technological progress has affected all areas of activity. The advent of smartphones, computers and other devices has had a significant impact on lifestyle. To work and do everyday business has become much simpler and easier. This could not but affect the physical activity of a person, which sharply decreased.

This situation adversely affects functional abilities, weakens the musculoskeletal system of a person. Internal organs begin to work a little differently, but, unfortunately, changes are taking place for the worse, and not for the better. And since movements are minimized, a dramatically falling level of energy costs entails disruptions in the muscular, cardiac, vascular and respiratory systems. All this affects the body and health, and causes many diseases to develop.

Sport allows you to compensate for the lack of movement, increase energy costs. In addition, in the realities of modernity, it is sports and physical education that become the only available ways of manifesting activity, allowing to fill the natural need of each person in a certain amount of stress and movement.

The dependence of systems and organs on sports

Active physical activity, which is characteristic of absolutely any sport, has a positive effect on people's health. Countless studies, scientific papers, dissertations, and articles are devoted to this indisputable argument. If to state their essence briefly and, in essence, then the positive impact of sports on health comes down to the following specific points:

Strengthening the musculoskeletal system

Bones become resistant to stress, and muscles, increasing in volume, gain greater strength. During jogging, swimming, and exercising in the gym, there is an improvement in the transport of oxygen to the muscles, which activates previously resting blood capillaries and the subsequent formation of new blood vessels. The receipt of a large amount of oxygen changes the chemical composition of muscle tissue - the concentration of energy substances increases, and metabolic processes, including protein synthesis, begin to proceed faster, new muscle cells are formed. Strengthening the musculoskeletal system reduces the risk of developing osteochondrosis, osteoporosis, atherosclerosis, arthrosis, and herniated discs.

Strengthening and developing the nervous system

This is facilitated by an increase in speed and agility, improved coordination. There is a continuous formation of new conditioned reflexes, fixed and developing in a certain sequence. The body begins to adapt to increasing loads, performing exercises becomes much simpler and more effective, and less effort is applied. An increase in the speed of nervous processes leads to the fact that the brain responds faster to external stimuli and makes the right decisions.

Improving the function of blood vessels and the heart

Blood vessels and heart muscle become sturdier. During training, the organs function in a more intensive mode, and the muscles under the influence of loads require increased blood supply. The vessels and heart begin to pump more oxygenated blood, the volume of which rises to 10-20 liters per minute, instead of 5 liters. The cardiovascular system in people leading an active lifestyle quickly adapts to stress and recovers after each workout.

Improvement of the respiratory system

Achieved as a result of the increasing need for organs and tissues in oxygen. Due to this, the depth and intensity of breathing increases. Against the background of no loads, the amount of oxygen passing through the respiratory system in 60 seconds is 8 liters, and during swimming, running, and exercising in the gym, it increases to 100 liters, that is, the lung capacity is increased.

Improving the protective functions of the immune system and a qualitative change in blood composition

The number of red blood cells contained in a cubic millimeter in people training on an ongoing basis rises from 5 to 6 million. Increases the level of white blood cells - lymphocytes that neutralize harmful factors. The overall strengthening of the immune system is direct evidence of the positive effects of physical education. People who are constantly engaged in any kind of sport or attending a gym are much less likely to get sick, recover faster.

Improve metabolism

In a trained body, the process of regulating the content of sugar and other substances in the blood is much better.

Changing attitudes to life

Leading an active lifestyle, people are less prone to mood swings, neurosis, depression, less irritable and more cheerful.

The problem of the popularization of physical education and sports

The beneficial effect of physical activity on the human body is confirmed by research, practical observations, is reflected in numerous proverbs from different peoples of the world.

Both teachers and doctors make a lot of efforts to ensure that a positive attitude towards sports has developed in society. In educational institutions give out free subscriptions for visits to gyms and pools. These efforts, of course, are bearing fruit, but the number of people ignoring sports and physical education is quite large.

Sports, of course, are important and necessary for everyone. The main thing is to observe moderation and avoid overloads. We should not forget about the injuries that can be obtained if neglected safety measures.
