Major health changes in the respiratory system when
Increased respiratory rate. If at rest breathing rate is 12-18
respiratory movements (take a breath cycles) per minute, then at work, she
increased to 40-90 breaths depending on the intensity
Increased depth of breathing. If the depth of breathing at rest (the volume of air
inhaled or exhaled in one breath or exhale) is 0.5 litersthat
during intense muscular exercise, it increases to 2-3 liters.
Dilate the blood vessels of the lungs and respiratory tract (as well as
respiratory muscles). The rate of blood flow through the vessels of these organs.
Increased activity of the respiratory system during work (together with
increase in the cardiovascular system, blood system and other
systems) provides an increase in consumption of oxygen in several
dozens of times. Thus, at rest the body consumes 250-350 milliliters of oxygen
per minute, and at maximum muscle work, this value may reach 4
liters per minute (Grajewo ND 1976).
Major health changes in the respiratory system under the influence
systematic fitness training.
As a result of systematic physical exercises are
Such changes in the respiratory system, which provide increased
body oxygen consumption during muscular work.
Increased strength of respiratory muscles. The volume of maximal inspiratory
or expiration.As a result, a breathing motion of the lungs may
received a lot of air.
