Long-distance running can make the heart stronger, thus supplying blood to the body more calmly, thus reducing the pressure on blood vessels. Of course, when the vascular pressure decreases, the blood pressure can also decrease. Persisting in long-distance running can also exercise and enhance the heart function, which is manifested by thickening the ventricular wall of myocardium, enhancing the contractility and increasing the cardiac output. The function of the heart is to pump blood, or circulate blood, which enters all parts of the body through blood vessels. Blood provides nutrition and oxygen for the body. All cells need oxygen to survive.
Therefore, long-distance running can increase the muscle contraction ability of the heart, thus indirectly enhancing the function of the heart, because running benefits the heart the most. .
