Enlist the effects of exercises on respiratory system.

Effects of Exercises on Respiratory System :
Regular exercises have following effects on respiratory system :
(a) Increase in Size of Lungs and Chest. When person performs exercise regularly, he equires more amount of 02. He inhales more amount of air during exercise. Consequently, his lungs and chest are exercised. After some period, the size of his lungs and chest increases.
(b) Increase in Residual Air Volume. Residual air is that amount of air, which is left in the lungs after exhalation. If an individual performs regular, exercise, his residual air capacity increases in comparison to an individual who does not perform regular exercise.
© Increase in Endurance. If exercise is performed regularly and for a longer period, it increases endurance. An activity can be done for a longer period without taking any rest. Those who do not perform exercise, have less endurance. They cannot continue exercise for a long duration. Hence, it can be alluded that exercise increases the endurance of an individual.
(d) Unused Alveoles Become Active. Regular exercise activates the unused alveoles, because much amount of 02 is required in vigorous and prolonged exercise of daily routine. The passive alveoles become active.
(e) Avoids Second Wind. For a beginner, the stage of second wind is, indeed, a crucial stage. But for a regular exerciser, it is hardly felt. Sometimes, a well-experienced athlete does not feel it in his course of activity.
(f) Strengthens Diaphragm and Muscles. Regular exercise strengthens the diaphragm and the muscles of the chest.
(g) Decrease in Rate of Respiration. It is certain that when a beginner starts exercise, his rate of respiration increases. But when the same individual performs exercise daily, his rate of respiration decreases in comparison to the beginning stage at rest.
(h) 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 800 cc. After doing regular exercise, it has been noted that this tidal air capacity can be increased.
(i) Strong Will-power. Regular exercises increase will power of the individual. As paranayama, the specific exercise for lungs increases the will-power of the doer.
(j) Prevention from Diseases. An individual’s, who does not perform any exercise, speed of inhalation and exhalation becomes less. The waste products start sticking in his lungs and with the passage of time his lungs get damaged. On the .other hand, if we perform regular exercise, we will have to inhale and exhale more air speedily. By doing so, the waste products will never stick in our lungs. These products will come out automatically and the lungs will not be damaged. In this way, it can be said that by doing exercise we can prevent various diseases.
