Running can protect the heart, which is an important organ of the human body that is prone to aging. The normal function of the heart has a direct impact on the functions of other internal organs. Medically speaking, to stay healthy, we must first maintain the heart function. Middle-aged people are prone to ischemic heart disease, which leads to myocardial ischemia due to coronary artery occlusion, leading to angina pectoris and myocardial infarction. Running exercise can keep good blood circulation of coronary artery. Long-term running exercise will not narrow the coronary artery due to age, and ensure that there is enough blood to supply the myocardium, thus preventing various heart diseases and maintaining good heart function.

Running is a whole-body exercise, which can accelerate the whole-body blood circulation, speed up the whole-body blood distribution and eliminate congestion. Through the movement of lower limbs, the human body is pushed forward, and at the same time, venous blood is strongly driven to return to the heart, so as to reduce venous and pelvic congestion of lower limbs and prevent venous thrombosis. Running can regulate the excitement and inhibition of cerebral cortex, improve the function of nervous system and eliminate the fatigue of mental work. Prevent neurasthenia and diabetes.

Running can also adjust the internal balance of human body, adjust mood, cheer up, improve material metabolism, promote metabolism, reduce blood lipid level and cholesterol level, control human body weight and lose weight. People who often practice long-distance running will be deeper, and the effect of strengthening the heart is obvious.
