010-111 Question #15: Real Exam Question with Answer & Explanation
The correct answer is C. Systolic BP increases proportionately to increases in workload and diastolic BP remains. During aerobic exercise, systolic BP rises proportionately with workload intensity while diastolic BP remains relatively stable. This reflects the interplay between increasing cardiac output and peripheral vasodilation in active muscles.
Question
Which of the following is a normal blood pressure (BP) response to aerobic exercise?
Options
- ABoth systolic and diastolic BP increase proportionately to increases in workload.
- BSystolic BP increases and diastolic BP decreases.
- CSystolic BP increases proportionately to increases in workload and diastolic BP remains
- DSystolic and diastolic BP both decrease at the onset of exercise, then increase in proportion to the
Explanation
During aerobic exercise, systolic BP rises proportionately with workload intensity while diastolic BP remains relatively stable. This reflects the interplay between increasing cardiac output and peripheral vasodilation in active muscles.
Common mistakes.
- A. Diastolic BP does not rise proportionately with workload because peripheral vasodilation in working muscles lowers vascular resistance and blunts any diastolic increase.
- B. While systolic BP does rise, diastolic BP does not significantly decrease during moderate aerobic exercise - it stabilizes rather than drops.
- D. Systolic BP does not decrease at exercise onset; it increases immediately due to sympathetic activation and rising cardiac output from the start of exertion.
