010-111 Question #9: Real Exam Question with Answer & Explanation
The correct answer is B. Total lung volume will increase in proportion to the total accumulated time of high-intensity. Aerobic training produces several well-documented physiological adaptations, but total lung volume is a structural measurement that does not increase proportionally with accumulated high-intensity exercise time.
Question
Which of the following physiological changes does NOT occur when a client improves aerobic capacity?
Options
- AThe muscles will be able to extract more oxygen from the blood.
- BTotal lung volume will increase in proportion to the total accumulated time of high-intensity
- CThe oxygen carrying capacity of the blood will increase.
- DThe amount of air the lungs can take in will increase because of increases in the rate and depth of
Explanation
Aerobic training produces several well-documented physiological adaptations, but total lung volume is a structural measurement that does not increase proportionally with accumulated high-intensity exercise time.
Common mistakes.
- A. Improved aerobic capacity genuinely increases the muscles' ability to extract oxygen from blood, reflected by a widened arteriovenous oxygen difference, making this a true and expected adaptation.
- C. Aerobic training increases red blood cell count and hemoglobin concentration, which directly raises the oxygen-carrying capacity of the blood, making this a confirmed training adaptation.
- D. Aerobic training improves the ability to increase both rate and depth of breathing during exercise, allowing greater pulmonary ventilation, which is a true adaptation and not the exception.
Concept tested. Aerobic training adaptations - pulmonary versus systemic
