As the intensity of dynamic exercise increases, which acute responses occurs?

Question

Quizplus · Accepted Answer

As the intensity of dynamic exercise increases, the heart pumps more blood to meet the demands of the working muscles. This results in an increase in heart rate and systolic blood pressure. However, diastolic pressure usually remains unchanged or may even decrease slightly due to the vasodilation of blood vessels in the muscles, which allows for increased blood flow. Stroke volume increases initially but then plateaus, so cardiac output increases. Therefore, choice B is the best option as it accurately reflects the acute responses to dynamic exercise.
