Muscles rights are a powerful generator of energy. They send a strong the flow of nerve impulses for optimal tone polderzhaniya CNS vessels to heart ("muscle pump")create the necessary voltage for normal operation of locomotive. According to the "energy rule skeletal muscles' energy potential and functional status all organs and systems depends on the nature of the skeletal muscles. Than intense motor activity within the optimum range, the more implemented a genetic program, and increased energy potential, functional resources of the body and life expectancy.(Sudzilovsky FW 1997).

Distinguish general and special effect of physical exercise, as well as their indirect influence on the risk factors. The most common effect of exercise is the energy consumption is directly proportional to the duration and intensity of muscle activity,that allows you to compensate the deficit energy. Also important is the increasing resistance to Effects of environmental factors: stress,high and low temperatures, radiation, trauma,hypoxia. As a result, increasing nonspecific immunity and increases resistance to colds diseases. However, the use of limit training loads required in professional sport to achieve "peak" fitness, often has the opposite effect, inhibition of immunity and increase susceptibility to infectious diseases. A similar negative effect can be obtained when doing mass physical culture with excessive increasing load. (IV Smirnov 2001).

Special effect of fitness training is associated with a positive impact on bones involved. It is known that bone tissue is constantly updated, this process is quite natural for a healthy body. During childhood and adolescence the bones increasing their maximum density, then Several years later,begins the annual loss of bone mass - 1% in Year of the total bone mass,post-menopausal women, these losses increase to 2 - 3% annually,and since the age of new tissue formed all slower and faster than the old lost, bones become thinner,become brittle. (Dorofeeva TS 1997).
