It is best not for middle-aged and elderly people to do push-ups

　　push-ups exercise It not only exercises the shoulder joints and elbow joints, but also exercises the flexor and extensor muscles of the upper limbs and the muscles of the shoulders, back, abdomen and thorax. Even the muscles of the buttocks and lower limbs also participate in static contraction. While maintaining the coordinated movement of flexion and extension of the upper and lower limbs, it also incorporates breathing exercises to promote blood circulation throughout the body and enhance cardiopulmonary function, so this is a good whole-body exercise.

　　However, push-ups accelerate blood circulation throughout the body, and holding your breath during push-ups can instantly increase intrathoracic and intra-abdominal pressure, prompting blood from the thoracic and abdominal organs to quickly flow back to the heart, which can also cause a sharp increase in blood pressure. Experiments have found that the blood pressure of bodybuilders when doing push-ups is heart rate 20% to 30% higher than at rest. Push-ups are a sudden exertion of force from a static state. While the blood pressure rises rapidly in an instant, it also increases the load on the heart, greatly increases the oxygen consumption of the myocardium, blood is diverted to the muscles, and the heart blood flow is relatively reduced. Therefore, for people with existing underlying diseases, fatal diseases such as angina pectoris, arrhythmia, cardiac insufficiency, embolism, and bleeding may occur when blindly performing push-ups. Take Uncle Motoyama as an example. He originally suffered from an undetected cerebral hemangioma and possible arteriosclerosis and poor elasticity of blood vessels. When he did push-ups, his blood pressure increased, triggering the rupture and bleeding of the intracranial aneurysm.

　　In 2007, Yale University in the United States conducted a survey on 90 patients with ruptured aortic aneurysms. The results found that 24% of people had done heavy physical labor within 1 hour before the onset of illness, including doing push-ups. And in our country, male The rate of arteriosclerosis between the ages of 50 and 59 is 86.2%. female At 60%, the risks of these people doing push-ups cannot be ignored.
