Why does systolic blood pressure increase sharply and diastolic blood pressure decreases slightly af

A large increase in systolic blood pressure and a small decrease in diastolic blood pressure after exercise are mainly caused by the following reasons:

1.Increased sympathetic excitability: After exercise, the body's sympathetic excitability increases, resulting in increased secretion of substances such as catecholamines. These substances can cause the heart to beat faster and increase the contractility of the heart muscle, which can lead to a temporary increase in blood pressure.

2.Temporary dehydration: Sweating during exercise can lead to temporary dehydration. This can lead to increased blood viscosity and resistance to blood flow, which in turn can lead to an increase in blood pressure.

3.Vasodilation of muscles: After exercise, muscle vasodilates to adapt to the body's needs, providing more blood and oxygen**. This can also lead to some increase in blood pressure.

4.Vasoconstriction: After exercise, ** and splanchnic blood vessels may constrict, increasing peripheral vascular resistance, resulting in increased systolic blood pressure.

This condition is a normal physiological phenomenon, usually within a period of time after the end of exercise, the body automatically regulates blood pressure to a normal level, so there is no need to worry too much. However, if there is a significant increase in blood pressure and uncomfortable symptoms after exercise, it is recommended to seek medical attention in time.

You are correct in explaining the increase in systolic blood pressure. But why does diastolic blood pressure drop slightly? This is due to the dilation of blood vessels by exercise, which increases the passage of venous blood back to the heart and reduces diastolic blood pressure.

When the sympathetic nervous system is excited, the splanchnic blood vessels constrict, and the small blood vessels of the muscles dilate to improve the blood supply. At the same time, the contractility of the heart is strengthened, which is mainly manifested as positive inotropic effect, positive chronological effect, that is, increased heart rate. This can lead to an increase in blood pressure, especially systolic blood pressure.

After exercise, the muscle blood vessels open (because of the sympathetic vasomotor nerve, the sympathetic vasomotor nerves are mainly distributed in the skeletal muscle blood vessels), and the peripheral resistance decreases, causing a decrease in diastolic blood pressure, which is mainly related to peripheral vascular resistance.

Hello, your situation is similar to mine, I usually have high blood pressure when 150 100, after exercising below 85, sometimes drink a little beer, 115 77 can come out, blood pressure fluctuates greatly, it seems, you must exercise

Your question is very interesting, let me tell you my opinion; The so-called general situation means that the heart function is sound, and the exercise intensity is within the limit, when the body needs more blood to the skeletal muscle during the exercise process for the corresponding life response; Then the heart will contract and eject blood in a shorter time, and the natural systolic blood pressure will be higher than the original, and the diastolic blood pressure is related to the elasticity of the blood vessels themselves, so it is generally not affected; Back to the question, if the intensity of exercise reaches the limit of the heart's load, the heart will naturally feel very tired, and there will be contraction weakness (the heart also needs to rest), that is, the systolic blood pressure will decrease, and then the person will faint to the ground.

It's caused by exercise, it's fine, it's normal, but if you don't exercise, it comes down.

It's a result of exercise, right? In any case, there will definitely be a solution in medicine, just go to the hospital for consultation.

The heart rate becomes faster after moving the mold vertically. Changes in heart rate have a greater effect on diastolic blood pressure. The heart rate is increased, the diastolic phase is shorter, and the blood flow through the arterioles to the periphery is less in a shorter period of time, so the amount of blood stored in the aorta at the end of diastolic is increased, resulting in high diastolic blood pressure.

Post-exercise systolic blood pressure.

Elevated, diastolic blood pressure decreases.

The increase in systolic blood pressure is due to the stimulation of sympathetic nerves during exercise, the constriction of splanchnic blood vessels, the dilation of small blood vessels in the muscles to improve blood supply, and the strengthening of cardiac contractility, which is mainly manifested as positive inotropic effect, positive chronotropic effect, that is, increased heart rate, which will lead to an increase in blood pressure, especially systolic blood pressure.

The decrease in diastolic blood pressure is because after exercise, the muscle blood vessels are opened, because of the sympathetic vasomotor nerve, the sympathetic vasomotor nerve is mainly distributed in the skeletal muscle blood vessels, and the peripheral resistance is reduced, causing the diastolic blood pressure to decrease, and the diastolic blood pressure is mainly related to the peripheral vascular resistance.

Systolic blood pressure increases due to increased cardiac contractility Increases diastolic blood pressure due to exercise's fast heart rate Exercise skeletal muscle vasodilation causes diastolic blood pressure to decrease.

Condition analysis: It can be said that after exercise, due to the increase in the contractility rate of the heart, it can lead to an increase in systolic blood pressure, and because the fast heart rate after exercise, it can lead to an increase in diastolic blood pressure, and after exercise, skeletal muscle vasodilation can lead to a decrease in diastolic blood pressure

It can be said that after exercise, due to the increase in the contractility rate of the heart, it can lead to an increase in systolic blood pressure, and because the fast heart rate after exercise, it can lead to an increase in diastolic blood pressure after exercise, and the skeletal muscle vasodilation causes a decrease in diastolic blood pressure

Systolic blood pressure mainly reflects the contractile force of myocardium and stroke volume, and diastolic blood pressure mainly reflects the elasticity of arterial blood vessels and the resistance of peripheral small blood vessels. As soon as people start exercising, blood circulation accelerates, which proves that cardiac output rises sharply, so as to keep the amount of exercise proportional to oxygen consumption, naturally, with the increase of blood output during exercise, to ensure the normal energy supply for the body, the resistance of arteries and blood vessels will naturally be reduced, that is to say, diastolic blood pressure will be reduced! Therefore, the ideal blood pressure response after exercise should be an increase in systolic blood pressure, an appropriate decrease in diastolic blood pressure or the same as a reflection of cardiovascular function adaptation to exercise load!

Does measuring blood pressure after exercise affect the systolic blood pressure can increase significantly with exercise, especially if the systolic blood pressure rises to 24 0 to 26 7 kPa (180 to 200 mm Hg), but after exercise stops, the blood vessels dilate and the blood pressure drops again. Therefore, if you measure your blood pressure just after exercising, your blood pressure may be higher than usual, but after a period of time, it will be lower than usual.

Problems with exercise and blood pressure: After exercise, the heart rate increases and blood circulation increases, which will induce further increases in blood pressure, so it is not advisable to exercise vigorously.

Suggestion: You may wish to randomly measure your blood pressure 3 times (before exercising), if all 3 times are above 130 80 mm Hg, then you should pay attention to lifestyle changes to control your blood pressure. If you are above 140 90, it is recommended to consult a doctor with a vascular medicine number, so as not to be too troublesome.

It's good that there are no symptoms yet! But don't wait until you have symptoms to feel the need to control your blood pressure. When symptoms are present, most of the organ function is also impaired by prolonged hypertension, and the most common organ damage is the eyes and kidneys.

Aerobic exercise can be done in the following ways:

Walking: It can significantly reduce blood lipids in the body and relieve the tension of the central nervous system.

Jogging: Jogging improves the heart's pumping function and promotes blood circulation through continuous rhythmic breathing exercises, inhaling sufficient oxygen levels.

Qigong: It can strengthen the modulation process of the cerebral cortex, relax the mind, and relieve mental tension.

Tai Chi: Its movements are gentle, the posture is relaxed, and the muscles are relaxed, which reduces the peripheral vascular resistance and lowers blood pressure.

Swimming: The body is in a horizontal position when swimming, which reduces the burden on the heart, improves the function of blood vessels, and promotes blood redistribution.

Generally, a person's blood pressure drops after exercise. And it lasts for more than ten hours. Exercise can increase the concentration of some beneficial chemicals in the body, such as endorphins, serotonin, etc., reduce the level of substances that have a pressor-boosting effect, and lower blood pressure.

Rise. Blood circulation accelerates during exercise and cardiac output increases. Systolic blood pressure is increased due to increased cardiac output during exercise. In order to ensure the normal physiological needs of the body, the resistance of small blood vessels will be reduced, that is, the diastolic blood pressure will drop slightly.

Blood pressure will rise first and then fall, just after exercising, the blood circulation will speed up, which will naturally cause the blood pressure to rise, and then wait for the body to calm down, the blood circulation is normal, and the blood pressure will come down.

Why does blood pressure low blood pressure down to 53 after exercise
