It is said that fitness is a sport for young people, but for some middle-aged and elderly people, they can go to the hospital to consult a doctor according to their physical condition, and proper fitness is still possible. For example, it is very important to do some less strenuous fitness exercises, such as jogging and boxing, which are more suitable for middle-aged and elderly people, and exercise is very important, regardless of age.

In recent years, the concept of "national health" has become more and more popular. Many elderly friends began to take care of their bodies in various ways, so as to get healthier bodies and prolong their life. However, what kind of exercise is suitable for everyone, how much exercise and how long it lasts need to be decided according to the individual's gender, age and physique. For example, some old people always have a little knowledge of exercise to keep fit. Many times, exercise can not only strengthen the body, but also hurt the body. Today, we will talk about the matters needing attention in sports for the elderly. Everyone must pay more attention at ordinary times! ]

When lifting weights, the exerciser suddenly has a force. At this time, the vocal cords are closed, the pectoral muscles and abdominal muscles are suddenly shortened, and the pressure in the cavity suddenly rises. The increase of intracavitary pressure will affect the beating of the heart, and the venous blood return will be blocked after compressing the vena cava. As a result, the blood output of the heart decreases. When the blood supply to the brain of the elderly has been reduced, if the blood supply is cut off again, dizziness will occur, and it will only happen, and in severe cases, it will faint.

Although the output of the heart decreases when you hold your breath, your blood pressure will suddenly increase, especially the shortened pressure. This is because when most local muscle groups participate in exertion, the shortened muscles will squeeze blood vessels and the resistance of arterial blood flow will suddenly increase. By measuring the changes of blood pressure during weight lifting with advanced arterial intubation technology, it is found that some people's shortened blood pressure will suddenly rise to 200-300mmHg. In addition, in the process of weightlifting, blood pressure fluctuates greatly and very quickly.
