After Exercise Blood Pressure : An Explanation
Exercise causes major changes in the circulatory and respiratory systems, which both take place simultaneously as part of a homeostatic response. Body’s response to exercise involving muscle contractions can be an increase in heart rate. Besides a decline in total peripheral retention due to vasodilation in exercising muscles. As a result, the systolic blood pressure also improved although only a moderate increase, while diastolic generally tend not to change or fall. When exercising blood pressure will go up quite a lot. However, soon after the exercise is completed, the blood pressure will drop to below normal and lasts for 30-120 minutes. This decrease occurs because blood vessels widening and relaxation. In patients with hypertension, it will markedly decrease. If the exercise is done repeatedly, over time the reduction in blood pressure had lasted longer. After exercise blood pressure explanation, this is why exercise regularly can lower blood pressure.
Blood pressure will be decreased immediately after exercise dynamically tiring. Systole decrease of blood pressure is caused by vein blood concentration in leg still in a state of dilatation because of leg muscle pumping blood in the veins stop. Decreasing the number of returning blood to the heart, causing the cardiac output to be very low and allow people try the fainting, due to a lack of blood flow to the brain.
After exercise blood pressure drops drastically with this, actually can be avoided, if it continues to perform muscle movements with light levels (leg muscle) a few minutes after making the core motion, because such system of blood vessels have the chance gradually to adjust to the flow of blood from the muscles was at work, and widens the blood vessels of the skin and to the central circulation. If already very tired and unable to move the muscle again, you should lie down so as not to faint.
Normal Blood Pressure After Exercise
Blood pressure is considered normal if the systolic blood pressure did not exceed 140 mmHg and diastolic blood pressure did not exceed 90 mmHg in a resting state. Blood pressure is affected daily activities. Bedtime night blood pressure is at the lowest conditions (80-90 mmHg and 40-60 mmHg diastolic Sistolis. Conversely, the more active a person is getting his blood pressure rising. Within certain weight can reach 130-170 mmHg systolic and 100-120 mmHg. conceivably, the higher a person’s blood pressure higher power that pushes blood out. It is understood the higher a person’s blood pressure is getting dangerous, might be the blood vessels to be passed not afford anymore. It may also be broken and will cause paralysis or stroke.
In the body, there is a regulation mechanism of blood pressure, which is called the baroreceptor mechanism. Baroreceptors will be stimulated if there is an increase or decrease in blood pressure. When blood pressure increases (for example, when we finished the exercise), baroreceptors will stimulate the parasympathetic nervous system which lead to the receptors quickly send impulses to the vasomotor center, to inhibit the vasomotor center resulting in vasodilation (widening of blood vessels vasodilatation meaning, the opposite of vasoconstriction which I have described above) in the arterioles and veins and lower blood pressure. Dilatation of arterioles lowering peripheral resistance and dilated veins cause blood to accumulate in the veins, thereby reducing venous return and thus lower cardiac output. A baroreceptor afferent impulses that reach the heart will stimulate the parasympathetic activity and inhibit the sympathetic center, causing a decrease in heart rate and contraction force of the heart. In other words, there will be a decrease in cardiac output (including stroke volume and heart rate) and vasodilatation. A decrease in cardiac output would result in decreased heart rate and after exercise blood pressure return to normal as usual.
