Question
Discuss any five effects of exercise on respiratory system.
✓
Answer
Regular exercises have following effects on the respiratory system.
Strong Willpower: Regular exercises increase the willpower of the individual. For example, pranayama specific exercise for lungs, increases the willpower of the doer.
Increase in Tidal Air Capacity: Tidal air is the amount of air that flows in and out of the lungs in each quiet respiratory movement. But tidal air capacity is the amount of air that can be breathed in and breathed out, over and above the tidal air by the deepest possible inspiration/ expiration, respectively. It is estimated at about 500 to 800cc. After doing regular exercise, it has been noted that this tidal air capacity can be increased.
Decrease in Rate of Respiration: It is certain that when a beginner starts to exercise, his rate of respiration increases. But when the same individual performs exercise on a daily basis, his/ her rate of respiration at rest decreases in comparison to the earlier stage.
Strengthens Diaphragm and Muscles: Regular exercise strengthens the diaphragm and the muscles of the chest.
Avoids Second Wind: For a beginner, the stage of second wind (the ability to breathe freely after having been out of breath) is, indeed, a crucial stage. But for a person who does regular exercise, it is hardly felt. Sometimes, a well-experienced athlete does not feel it in his course of activity.
