THE FUNCTIONAL STATE OF CARDIOVASCULAR DISEASES

Despite over the past few decades incidence and mortality rates of cardiovascular disease are declining in many countries, there are currently still about 126 million cases of ischemic heart disease (IHD) in the world. IHD also remains one of the leading causes of death, accounting for over 9 million deaths per year worldwide. The aim of this review is to provide a detailed and updated description of the role of sport and physical activity both in primary prevention and secondary prevention. A child's body differs from an adult in rapid growth and development, active formation of organs and systems. Regular training in childhood increases the functional and adaptive reserves of the body, promotes health, and increases physical and mental performance [3]. Changes in the cardiovascular system, detected using functional diagnostics methods, are a kind of indicator of the adaptive activity of the whole body. The central link of the entire circulatory system is the heart, the functional state of which is also reflected in the electrical and mechanical manifestations of its activity [4]
