The influence of exercise on the human body

The body’s response to exercise

The usual reaction to physical exercise — the overall improvement of the functional state of the organism, i.e. the improvement of the life of the organism, directly identifies the degree of its resistance to any disease or medical conditions, previous diseases. The main role in this process plays the nervous system . it primarily acts a tonic effect of exercise . are balanced by the processes of excitation and inhibition in the Central nervous system, normalizes autonomic function, increases

mental performance, removed various brake condition in the brain that disrupt the work of the various bodies is to improve its steering and coordinating activities. Respectively return to normal function of individual organs and systems. For example, the main cause of bad posture in children is not anatomical defects and pathological degeneration of tissues, and the absence of nerve stereotype— skills to maintain the correct posture.

Under the influence of appropriate physical exercises is habitual, permanent communication: from the brain — to nerve wires to the muscles. This relationship (the stereotype) and causes your own muscles, providing correct posture. Physical exercises simultaneously increase the endurance and strength of muscles that support the correct relative positions of the bones of the human skeleton, without which it is impossible to constantly maintain the correct posture. The influence of exercise on the cardiovascular system is conditioned, on the one hand, exercise and strengthen the heart muscle, and the other — the normalization of a complex mechanism of regulation of work of the body and the circulation system, resulting in:

Improve coronary circulation and metabolic processes in the heart;

Improves venous hemodynamics, which promotes the flow of blood to the heart;

Increases the efficiency of the systole;

Reduced amounts of cholesterol in the blood. During exercise fats are not deposited in the subcutaneous tissue or vessels, and are consumed by the body.

Improves supply of blood to the heart muscle, normalizes the intensity of the General circulation and blood pressure;

The cardiovascular system interacts very closely with the respiratory system.

The reaction of the respiratory system on a regular exercise is

Improve the elasticity of the intercostal cartilage, thereby increasing the mobility of the diaphragm;

Strengthening the respiratory muscles (diaphragm, intercostal muscles);

Increase lung capacity;

The formation of correct breathing (slow in-depth exhalation with involvement of the abdominal muscles);

Improving pulmonary ventilation;

Economization of external respiration;

Improving the process of gas exchange in the lungs (improvement of arterial blood saturation with oxygen and remove carbon dioxide).

Specially selected exercises can improve the health of the gastrointestinal tract (eg. motor function), and influence on gastric secretion.

Thus, the intensification of nervous processes, improving lung function and cardiovascular system, normalize digestion improves the maintenance of all body tissues substances that regulate, stimulate metabolic processes, which, in turn, activates the body’s defenses, strengthens the body, increases resistance to diseases of civilization, improves health and enhances the quality of life. In other words, physical exercise has significant health and preventive effects on the human body.

Systematic physical exercises to reduce the likelihood of exacerbation of chronic diseases, delay the development of a pathological condition or correct existing violations called Wellness and prevention.

Health benefits from regular exercise is that:

physical exercise improves the function of the pancreas, which produces insulin — a hormone that breaks down glucose. In consequence of which improve the conditions of accumulation and rational energy expenditure of the body;

physical activity slows down the development of coronary atherosclerosis and thus prevents the emergence of a large number of heart diseases;

strengthen different muscle groups (including the body), improves posture and increases physical fitness and performance;

improves liver function — the main biochemical laboratory in the human body. Activates the production of enzymes and other equally important and necessary biologically active substances that increase the rate of purification of an organism from slags produced during the life of a person;

systematic physical exercises help to fix many physical defects of the human body, both congenital and acqui.

The value of exercise for formation of skeletal muscle
Power and the amount of the muscles are directly dependent on exercise and training. In the process, increases blood flow to the muscles, improves the regulation of their activity by…
