Knee joint injury caused by Lei Wen office workers climbing stairs for fitness. Miss Zhang is an office clerk. She usually spends a long time typing in the office and has little time for exercise, so she decided to climb the stairs to keep fit. The office is on the sixth floor. She chooses to climb stairs instead of taking the elevator every day. So is going home. A few weeks later, Miss Zhang vaguely felt pain in her knee, and the pain was even worse when she went up and down the stairs. The fitness program is a bit inadequate. I went to the hospital for examination and showed a slight injury to my knee. "Going upstairs into the elevator and going out by bus" has become a portrayal of the life of most urbanites. Coupled with the busy work, there is no time to exercise at all, so many people choose to take fewer elevators and climb more stairs, which not only achieves the purpose of exercise, but also saves time, but often uses the wrong method. Knee joint is an important part of human body. When people stand and walk on the flat ground, the weight borne by their knees is half of their body weight, while climbing stairs is mainly a lower limb movement, and the knees need to bend about 80 degrees, and bear the whole weight of their bodies at such an angle. Yang Dawei, chief physician of the Department of Orthopaedics, the Fourth Affiliated Hospital of Harbin Medical University, reminded that if you exercise by climbing stairs and repeating an action, it will not only wear the knee joint, but also cause impact syndrome and synovitis more easily. Especially the middle-aged and elderly people with osteoporosis are more likely to cause injuries. Climbing stairs is an aerobic exercise, which can exercise human internal organs and enhance the flexibility and strength of legs. But it is also necessary to talk about the method of climbing stairs: when climbing stairs, when the upward leg steps on the steps, the hind leg should be forced, not simply supported; When going down the stairs, your knees should be bent from your front foot to the next step to give your knees a buffer protection. When going down the stairs, the bearing capacity of the lower limbs increases. If you do this action repeatedly, the direct force on joints such as knees and ankles will also increase. Therefore, there is a folk saying that "going upstairs for fitness and going downstairs will hurt the body". Although fitness will make your body more and more flexible, you should also pay attention to moderate exercise. Special people are not suitable for climbing stairs for fitness. Yang Dawei said that stair climbing should not be a national fitness, nor should it be suitable for special people, such as people with knee joint trauma and old bone and joint injuries, and people over 40 should not choose stair climbing. People who have the conditions and good health should be careful when climbing stairs and master the correct exercise methods. Before climbing stairs, warm up your knees and ankles to avoid uncoordinated joint activities. Usually, it is best to do squats, standing and other exercises frequently, so that the joints can be fully exercised to prevent stiffness in the early stage of exercise. For sedentary people, Yang Dawei suggested that you'd better choose sports with weak antagonism, such as swimming, which is non-antagonistic and suitable for people of all ages. Other sports such as walking and jogging are good choices. Young people with physical strength and energy can also choose badminton and cycling. Share to: Welcome to comment, I want to comment.
