Final answer:
After exercise, systolic blood pressure initially increases to accommodate increased blood flow and then returns to normal. Diastolic pressure can show minor changes, and regular exercise contributes to better vascular health.
Step-by-step explanation:
After exercise, systolic blood pressure increases dramatically during the physical activity to increase blood flow and returns to normal afterward. This change helps improve the tone of the circulatory system and has no adverse effects. It is also beneficial because exercise leads to vascular improvements, such as better dilation and increased artery flexibility, which can contribute to lower blood pressure over time.
Regarding diastolic pressure, which is an indicator of fluid balance, it might not change as much during exercise. However, high diastolic pressure indicates that blood vessels are not dilating properly to pass blood through, which can strain the heart. After exercise, due to the physiological adaptations, diastolic pressure may decrease as vascular health improves.
