010-111 · Question #15

Which of the following is a normal blood pressure (BP) response to aerobic exercise?

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.

Why each option

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.

ABoth systolic and diastolic BP increase proportionately to increases in workload.

Diastolic BP does not rise proportionately with workload because peripheral vasodilation in working muscles lowers vascular resistance and blunts any diastolic increase.

BSystolic BP increases and diastolic BP decreases.

While systolic BP does rise, diastolic BP does not significantly decrease during moderate aerobic exercise - it stabilizes rather than drops.

CSystolic BP increases proportionately to increases in workload and diastolic BP remainsCorrect

Systolic BP increases during aerobic exercise because cardiac output rises with workload, generating greater pressure against arterial walls during ventricular contraction. Diastolic BP remains largely unchanged because vasodilation in active skeletal muscles reduces peripheral vascular resistance, offsetting the higher cardiac output and preventing a significant rise in diastolic pressure.

DSystolic and diastolic BP both decrease at the onset of exercise, then increase in proportion to the

Systolic BP does not decrease at exercise onset; it increases immediately due to sympathetic activation and rising cardiac output from the start of exertion.
