Extended data:

Bicycle is one of the best tools to overcome heart function problems. More than half of the people in the world die of heart disease. Riding a bicycle can not only compress the blood flow through the movement of the legs, but also pull the notes back to the heart from the vascular endings, and at the same time strengthen the microvascular tissue. This is the so-called "collateral circulation". Strengthening blood vessels can protect you from the threat of age and keep you young forever.

Cycling is a sport that needs a lot of oxygen. An old man rode a 460-kilometer bike in six days. He said: "Old people should take part in strenuous exercise at least three times a week to strengthen their hearts and make them healthier. Let the heart beat violently, but don't last too long, so that the heart can adapt to the emergency. "

Cycling exercise can also prevent high blood pressure, sometimes more effective than drugs, prevent obesity, arteriosclerosis and make bones strong. Bicycles can keep healthy without drugs and are harmless.

Sports experts pointed out that due to the special requirements of cycling, the arms and trunk mostly work statically, and the legs mostly work dynamically. When blood is redistributed, the blood supply of lower limbs is more, and the change of heart rate varies according to the speed of pedaling and the fluctuation of terrain.

There is an urgent need to replenish nutrients and discharge waste in the body, so the heart rate is often 2 ~ 3 times higher than usual. Repeated practice in this way can make the myocardium developed, the heart enlarged, the myocardial contraction strong, and the elasticity of the blood vessel wall enhanced. Therefore, lung ventilation, vital capacity and respiratory function have all increased.

In addition, cycling is an effective and cheap way to treat Parkinson's disease, which plays an important role in improving patients' overall health, balance and coordination, and relieving anxiety and depression.
