Final answer:
Systolic blood pressure is expected to increase during maximal incremental aerobic exercise to meet the higher oxygen and nutrient demands of the body.
Step-by-step explanation:
During maximal incremental aerobic exercise, systolic blood pressure (SBP) is expected to increase. This increase is a natural physiological response to exercise, as it helps to increase blood flow to meet the metabolic demands of the active muscles. With exercise, cardiac output (heart rate x stroke volume) escalates, and as a result, SBP rises.
For a healthy young adult, blood pressure may go from a baseline of approximately 120/80 mm Hg to higher levels during intense physical activity. For instance, an increase to about 185/75 mm Hg can be observed. However, well-trained aerobic athletes may see their SBP rise even further, potentially reaching 200/90 mm Hg at maximal exertion. Post-exercise, SBP should return to baseline values, which is an important aspect of cardiovascular homeostasis.
