Is square dancing bad for the knees when old people often do it?

　　Experts say that after the age of 30, the human knee joint begins to degenerate. At this time, it is necessary to protect the knee to prevent osteoarthritis. clinical Osteoarthritis is more common in patients over 50 years old, especially those who are obese female。

　　For people suffering from osteoarthritis, although physical therapy can relieve temporary pain, this disease It is particularly easy to relapse, so knee protection must be done adequately. Mountain climbing is an exercise that is not recommended by all orthopedic surgeons because it hurts the knees the most. “It is best not to climb mountains if you are over 30 years old. If you must climb mountains, do not do so frequently. Especially in autumn and winter, when the air is cold and the blood circulation in the joints is poor, the wear and tear on the joints will be greater. Climbing the mountain once a week at most, and not for more than 2 hours. ”Expert advice.

　　In addition, when climbing, be careful to choose a hill with a gentle slope that is not steep. Because the body weight can be evenly distributed throughout the knee joint, gentle slopes will cause less damage to the knees than concrete stairs built in the mountains. When walking steps, the focus is on the front half of the palm, and the pressure is concentrated on the front of the knee joint. In addition, roads built with cement are hard and cause greater damage to joints.

　　Going downhill is more damaging to the knee joints than going uphill, because when going downhill, almost all the weight is on the knee joints. After a knee joint injury, it is more difficult to go down the stairs than to go up the stairs. This is why. Therefore, taking the cable car down the mountain is also a good choice for knee pads.

　　In addition to mountain climbing, square dancing and Tai Chi can also hurt your knees.

　　Square dancing involves a lot of leg bending movements, and many people injure their waists and legs. The knee joint is most vulnerable when it is bent, and the angle of left-right rotation of the knee joint is small, so bending and turning the knee joint sideways is the most vulnerable to injury. There are a lot of such movements in badminton and square dancing, and there are many half-squatting postures in Tai Chi. Experts suggest that middle-aged and elderly friends who like these sports should stop doing them in moderation, do not do them for too long each time, do not do them too frequently, and the movements do not need to be too standard.

　　Exercise helps enhance physical fitness and makes people more healthy longevity. However, experts warn that excessive exercise may lead to osteoarthritis, so elderly friends should pay special attention. Once knee joint pain and swelling occur, seek medical attention promptly to avoid further pain.
