During exercise, in order to ensure the normal physiological needs of the human organs, the blood output of the heart increases, myocardial contractility increases, systolic blood pressure increases, peripheral resistance decreases, and diastolic blood pressure shows a mild decrease. After the end of exercise, blood circulation gradually returns to normal physiological speed, myocardial contractility gradually returns to normal range, and systolic and diastolic blood pressure also gradually returns to normal state. The other is diastolic blood pressure, which reflects the vascular elasticity and peripheral small vessel resistance in the body. Long-term exercise can reduce sympathetic excitation in the body, lower blood lipids, increase vascular elasticity, achieve the purpose of lowering blood pressure and improving heart efficacy.
