Question

For both types of exercise, the tidal volumes and breathing rates were increased. Compared with normal values, did tidal volume or breathing rate increase more during moderate exercise?

1) Tidal volume increased more
2) Breathing rate increased more
3) Both increased equally
4) Cannot be determined

Answer 1

During moderate exercise, tidal volume increases more compared to breathing rate.

Step-by-step explanation:

During moderate exercise, both the tidal volume and breathing rate increase. However, the tidal volume increases more compared to the breathing rate. Tidal volume refers to the amount of air that is inspired and expired during normal breathing, while breathing rate refers to the number of breaths per minute. Increasing the tidal volume allows for a greater intake of oxygen during exercise, while the breathing rate increases to meet the increased oxygen demand.
