A physiologist is trying to study the changes in teh blood pressure during exercise. He is conducting his study on healthy participants. During the study he asks to participants to run on a treadmill at incrementally increasing speed until their heart rate reaches 90% of their expected maximum heart rate. Compared to at rest, which of the following changes in blood pressure are expected during this time?

Eductional Objective: Diastolic blood pressure (DBP) is largely determined by systemic vascular resistance (SVR), and pulse pressure is largely determined by stroke volume.  During aerobic exercise, reduced SVR leads to slightly decreased or unchanged DBP, and increased stroke volume leads to increased pulse pressure and systolic blood pressure.
