Mine drops. I have read that it is also associated with a change in the size/resistance or?? of the blood vessels. Please see below and the link

Exercise Response

When you exercise, your working muscles need more blood and oxygen to function. This increased demand forces your heart to beat faster, thus pumping out more blood with each beat. When your heart rate and blood volume increases, so does the pressure of the blood on the arterial walls. Therefore, while you are actually engaging in exercise, your systolic blood pressure will temporarily rise, and your diastolic, or bottom number, will stay the same or drop slightly. The benefit of exercise on blood pressure occurs after physical activity. After a bout of exercise, the blood vessels throughout your body dilate. This relaxation of the vessels creates wider openings for the blood to flow through, therefore reducing the amount of resistance and pressure on the walls. This dilation can last for several hours after exercise, resulting in lower systolic and diastolic blood pressure readings.
