For the long-term preservation of the optimal physical status of a person, regular physical activity is required. Rational muscle activity can stimulate the entire body. It increases oxygen consumption and accelerates the release of toxic products, stimulates metabolism and protein synthesis. Frequent feasible physical training inhibits the development of pathological changes in the nervous system and internal organs. Systematic physical training has a strong healing effect on the musculoskeletal system and activates the entire endocrine system. With regular exercise, blood and venous pressure are normalized and lymph circulation is enhanced. Physical activity normalizes the processes of humoral regulation in all body systems. The most pronounced positive effect develops in the case of a combination of feasible exercises that stimulate different muscle regions. This leads to the activation of biosynthetic processes in all cells of the body. Regular dosed physical activity with optimal nutrition and sufficient sleep has a strong stimulating effect on physical capabilities and mental performance.
