How does the systolic blood pressure change during physical activity?

During physical activity, systolic blood pressure typically increases. This reaction occurs because as muscles engage and require more oxygen and nutrients, the heart pumps more blood to meet these elevated demands. The increased heart rate and the stronger contractions of the heart lead to higher cardiac output, which is reflected in the systolic blood pressure measurement.

As exercise intensity increases, the body must ensure that adequate blood is delivered to the muscles, causing systolic pressure to rise in response. This is a normal physiological response and indicates that the cardiovascular system is functioning effectively to support physical exertion.

In contrast, during rest, systolic blood pressure is generally lower. Choices that suggest a decrease, remain constant, or fluctuate wildly do not align with the physiological understanding of how the body responds to exercise.
