The mechanisms of the therapeutic action of physical exercises

Therapeutic effect of exercise based on positive influence of muscular activity on function of the heart and blood vessels. When the muscles of the cardiovascular system, stimulates blood circulation and thus gives the opportunity to continue working. Therefore, with the help of physical exercises can provide targeted action on many of the functions of the cardiovascular system. In diseases of the heart and vascular exercise improve adaptation processes in the cardiovascular system, consisting in the increase of energy and regenerative mechanisms that restore the disturbed functions and structures.
The interaction of the working muscles with the activity of the cardiovascular system is multi-apparatus regulatory systems functioning on the basis of cybernetic feedback (P. K. Anokhin).
Exercise improves the trophic processes. They increase the blood supply to the heart by increasing coronary blood flow, disclosure reserve capillaries and development of collaterals, stimulate the metabolism. All this stimulates the regenerative processes in the myocardium, increases contractile ability. Exercise improves and General metabolism in the body, reduce the amount of cholesterol in the blood, delaying the development of atherosclerosis.
Systematic exercise influence HELL through many links regulatory systems prolonged exposure. So, gradual and dosed training increases tone wandering nerve and hormone products (for example, prostaglandins), reducing AD. The result alone reduced variation and AD.
One should dwell on special exercises which give effect mainly through the nervous-reflexive mechanisms, reduce HELL. So, breathing exercises with extended exhale and ischemia of breath decrease in the heart rate. Exercise in relaxation of the muscles, and exercises for small groups of muscles of lower tone arteriol and reduces the peripheral resistance to blood flow.
In many diseases of the cardiovascular system is limited movement of the patient. In this case, the exercise becomes increasingly more important. They provide a General tonic effect, improves the function of all organs and systems and thanks to warn complications, activate protective forces of the organism and accelerate the recovery.
In severe condition of the patient are physical exercises that action through extracardiac (non cardiac) factors of blood circulation. So, exercises for small groups of muscles contribute to the promotion of blood through the veins, acting as a muscle pump, and causing expansion arterioles, reduces force on resistance arterial blood flow. Breathing exercises contribute to the inflow of venous blood to the heart due to the rhythmic change of intra-abdominal and intrathoracic pressure. During inhalation, the negative pressure in the chest cavity has a suction effect, and thus increasing intra-abdominal pressure as if to squeeze blood from the abdomen to the chest. During exhalation intra-abdominal pressure is reduced, making it easier to promote venous blood from the lower extremities.
Normalization of the functions is achieved by a gradual and careful exercise that strengthens the heart and improves contractility, restores vascular reaction of muscle work and change of body position. Exercise improves the function of the regulatory bodies, their ability to coordinate the work of the cardiovascular, respiratory and other systems of the body during exercise. This improves its ability to perform more work.
Physical training is of great importance for the prevention of cardio-vascular system, as it makes the lack of motive activity of a modern person. Exercise increases the overall adaptive capacity of the organism, its resistance to various stress, improving emotional state. Activation of motor mode with the help of various physical exercise improves functions of the systems governing the circulation, improves a contractile ability of the myocardium, reduces the Content of lipids and cholesterol in the blood, increases the activity of anti-clotting system, blood, promotes the development of collateral vessels, reduces hypoxia, i.e., prevents and eliminates the manifestation of the majority of risk factors of major diseases of the cardiovascular system.
Thus, physical culture is shown to all people not only as a health, but also as a preventive tool. It is especially necessary for those who are healthy, but has any of the risk factors for cardiovascular disease (see "Atherosclerosis"), as well as those who suffered the disease of cardiovascular system, as prevention of its recurrence or exacerbation of chronic diseases.
