Quizplus · Accepted Answer

During dynamic (isotonic) incremental exercise, the increase in mean arterial blood pressure is primarily due to the increase in systolic blood pressure. This is because the increased muscle contraction during exercise leads to increased cardiac output and stroke volume, which in turn increases systolic blood pressure. While diastolic blood pressure may also increase slightly, it does not significantly contribute to the overall increase in mean arterial blood pressure.
