How does exercise increase minute ventilation?
Minute ventilation is the amount of oxygen inspired by the body in a minute. It is increased by long term exercise because over time the body becomes more adept at bringing more oxygen in to the lungs to be taken to the working muscles. As tidal volume and breathing rate increases the minute ventilation will increase as more breathes will be needed to be taken to meet the high demand for oxygen. A healthy young person will take around 35-45 breathes per minute where as an athlete may take around 60-70 breaths per minute.
