Orthopedic surgeon Dr. Han Yixiong once described stair climbing or mountain climbing as “the dumbest sport”, and Chung Pei-chun, director of the rehabilitation department at Taian Hospital, also said that stair climbing or mountain climbing has the advantage of enhancing cardiorespiratory fitness and consuming calories, but the disadvantages are so serious that the benefits do not outweigh the losses. So practicing medicine for 30 years from the patient has never been advised to climb stairs or climbing as a sport. Who is suitable to use stair climbing or mountain climbing for exercise? Who should stay away from it? The Taipei 101 International Stair Climbing Competition and the Hsin Kuang Skyscraper Climbing Competition have just been completed, and the trend of stair climbing for all people to take care of their health is flourishing. The New England Journal of Medicine study also pointed out that climbing stairs can prolong life, each climb a step to live 4 seconds more. However, we often see people struggling on the stairs, knee pain to no way up the stairs, or even the more you climb the more serious knee problems. In the end, climbing stairs or climbing is not a good exercise? Unrecoverable wear and tear on the knees! Climbing stairs or mountains is a weight-bearing exercise, the joints below the waist have to bear the weight of their own bodies, especially the knees are subject to the most force. When the body climbs up the stairs, the weight on the knees will instantly increase to about 4 times the normal weight. To a weight of 60 kilograms of people, for example, walking on a flat road on both sides of the knee each bearing 60 kilograms, but climbing stairs or climbing the mountain when the knee weight becomes as high as 240 kilograms, equivalent to the two sides of the knee each carrying the weight of a piano. And if the speed is accelerated, the pressure on the knee is greater. And weight is the biggest enemy of the knee joint. Orthopaedic surgeon analysis, climbing stairs or climbing when the knee in addition to increased weight-bearing, but also to move back and forth, side to side twisting, especially in front of the patella part of the knee joints to withstand the greatest pressure on the meniscus and other joint soft tissues will also cause wear and tear. Therefore, the body has a specific condition of the best people do not climb stairs or climbing as a sport, such as: 1, pregnant women or overweight people, because any excess weight on the knee is double the burden. 2, people with degenerative arthritis, because the soft tissues of the knee have been excessive wear and tear, continue to improper use will make the symptoms worse. 3, people with patellar valgus problems, because the patella is inherently unstable, often climbing stairs or climbing mountains will make the valgus problem worse. 4, O-legged people with more wear and tear on the inner knee, excessive stair climbing or mountain climbing will accelerate the wear and tear of soft tissue on the inner side of the knee, degradation, making O-leg symptoms more pronounced. 5, people with cardiovascular disease should be careful when climbing stairs or mountains, because the heart’s demand for oxygen will increase. If there is not enough oxygen at once, it may lead to myocardial infarction, and even sudden death if it is not sent to the doctor in time for treatment. 6, people over 40 years of age, because the function of various parts of the body gradually deteriorate, it is recommended that it is best to climb fewer stairs or climbing, walking in place is better than climbing stairs or climbing, the degree of damage is also small.
