[The respiratory and circulatory reactions to muscle loading and their relationships with the autonomic nervous system].
Research have been carried out on coal miners of the age of 30-35. It was determined that sympathonics have tension regular system of organism, connected with decline of reserve possibilities of parasympathetic nervous system. In conditions of muscular load it leads to the overstrain of myocardium, worsen of restoration processes, decline of aerobic and physical productivity of organism. High reactivity of vagotonic's sympathetic nervous system in combination with parasympathetic nervous system cause considerable activity of cardiovascular functions with less tension of myocardium and shortage of restoration period. Vital energy maintenance of organism with muscular work of people, having normatonia, take place mainly owing to the function of external breathing and it promotes saving of reserves of circulatory system and progress of a large aerobic and physical capacity to work.
