Question

what happens to someones blood pressure during dynamic exercise
systolic blood pressure decreases and diastolic blood pressure increases
blood pressure remains unchanged
both systolic and diastolic blood pressure increase proportionally with exercise intensity
systolic blood pressure increases and diastolic blood pressure remains constant

Explanation:

During dynamic exercise, the heart has to pump more blood to meet the increased oxygen - demand of the muscles. Systolic blood pressure increases as the heart contracts more forcefully to push the blood out. Diastolic blood pressure stays relatively constant as the blood vessels vasodilate to allow for increased blood flow, offsetting the usual increase that would occur due to increased cardiac output.

Answer:

Systolic blood pressure increases and diastolic blood pressure remains constant
