Normally, blood pressure during exercise will show an increase in systolic blood pressure while diastolic blood pressure remains the same or decreases. Blood pressure is the pressure produced on blood vessels during blood flow, usually expressed as systolic (high pressure) and diastolic (low pressure) pressure. When measuring blood pressure, it is necessary to be at rest. Exercise has a certain effect on blood pressure: the heart rate will accelerate during exercise, and within a certain heart rate range, the faster the heart rate, the more blood the heart pumps, and the higher the systolic blood pressure will be, because the heart’s contraction frequency cannot increase indefinitely, so the systolic blood pressure cannot increase indefinitely, plus the body’s nervous system will also participate in the regulation of blood pressure during activity. The systolic blood pressure of a normal person will increase within a certain range during exercise, and will rise by 20-30mmHg. As for diastolic blood pressure, it is mainly the elasticity of the arterial vessels and the resistance to blood flow generated by the peripheral small vessels. The demand for oxygen by various tissues and organs of the body increases during exercise, and in order to ensure that they can receive sufficient oxygen and at the same time reduce the pressure of blood flowing back to the heart, under the action of the body’s blood pressure regulating mechanism The resistance produced by the arterial vessels throughout the body decreases, with the result that the diastolic blood pressure remains almost unchanged or decreases during exercise. However, there is also a type of hypertension called exercise hypertension, which refers to a resting blood pressure within the normal range, but the systolic blood pressure during exercise is greater than 210 mmHg in men and 190 mmHg in women, the principle of its occurrence is still unclear, but it is certain that people with exercise hypertension have a much higher chance of getting hypertension in the future than normal people, and the chance of cardiovascular disease in the future will also increase significantly. Therefore, it is often used as an indicator to predict the risk of hypertension and cardiovascular disease. For such patients, 24-hour ambulatory blood pressure monitoring or an exercise panel test is recommended, or blood pressure should be measured within 2 minutes after exercise. Blood pressure usually increases after exercise, but when exercising and feeling dizziness, chest tightness, chest pain, or shortness of breath, you should immediately stop exercising and go to the hospital to find the cause and actively intervene in treatment.
