Exam 23: Cardiopulmonary Response to Exercise in Health and Disease

What is the respiratory quotient?

Which of the following is the formula used to calculate the predicted maximum heart rate for adults?

Which of the following statements apply to $\dot V$ _E? I.Normal people increase $\dot V$ _E by raising both the tidal volume and respiratory rate. II.Early in exercise a higher tidal volume produces most of the increase in $\dot V$ _E. III.Early in exercise a respiratory rate produces most of the increase in VE. IV.After approximately 60% to 70% of the vital capacity is reached, tidal volume plateaus, and increased respiratory rate is responsible for additional VE increases.

Which of the following are the major energy sources for ATP synthesis? I.Carbohydrates II.Fats III.Amino acids IV.Proteins
