A. What was the difference between the estimated versus actual forced tidal volume? When might it be useful to use the estimated numbers instead of measurements?
B. How do the minute ventilation (VE) values change during exercise? Why does this occur? Heart rate increases with exercise as well. How does this relate to external respiration?
C. Do you think that the forced vital capacity (FVC) of a person would change as that person increases exercise training? Why or why not? How might exercise training affect a person’s ability to increase VE during exercise?
D. An increase in age usually decreases the forced vital capacity of an individual. Why do you think this might occur?
