Answer:
The answer to the question: What is the expected response of the systolic blood pressure (SBP) as workloads increase during a graded exercise test, would be, B: The SBP should increase.
Explanation:
Systolic blood pressure is basically the force that the blood exerts over the vessel walls, as it travels through them, once it is ejected from the heart. The blood volume, the amount that is pumped by the heart, and also the resistance placed by the vessels themselves against the blood, all contribute to blood pressure. The name of systolic, or diastolic, comes from the two cycles of the heart, systole, when most of the blood is actively ejected from the heart, and the other when the heart begins to relax and prepare for a new pump. During exercise, especially if it is moderate and increasing, what is expected is for SBP to rise, until 2 to 3 minutes into it, the rising levels off, and becomes constant. But intially, it will rise.
