5.3.1 Short Term Effects of Exercise

Respiratory Rate Increases
During activity our muscles require oxygen and produce carbon dioxide; to
match the demand lungs have to work hard in this process so that lungs can
pump more oxygen into blood and out to the muscles. Our breathing rate
increases, sometimes it may reach to 40 breaths per minute as their resting
breathing rate is around 15 per minute.
Tidal volume Increases

The volume of air inhaled and exhaled in one breath is known as tidal volume.
As you know pulmonary ventilation increases because of size in tidal volume
and respiratory rate to meet increased oxygen demands.
