The character and ratio of
breathing is dynamic and is a result of the activity and the emotional state of
one. The breathing is performed via the nose mouth or both, depending on the
level of emotional arousal and physical activity. This is also the kind of breathing that
animals like dogs and cats use naturally and unconsciously.
Pure aerobic activity can last for a long time.
While performing pure aerobic activity oxygen
plays a most important role as an energy source for the muscles so large
quantities of incoming air and oxygenated blood are needed. High enough quantities
of carbon dioxide are also needed in the blood, otherwise the oxygen will
connect too strongly to the hemoglobin in the blood and will not be delivered
to muscles and internal organs properly.
Pure anaerobic activity, on the other hand, can
last only for a short time. The oxygen doesn't play in this type of activity
any significant role as an energy source for the muscles.
Pure aerobic or anaerobic activity is an only
theoretical model and in real life such a thing does not exist, rather there
are mostly this or that type of activity with very dynamic and constant
changes.
