As the saying goes, old age comes before old legs. At a certain age, after so many years of walking and “using”, many elderly people have more or less problems with their joints, such as knee pain, squatting and straining. So, as a special group of people, is there a secret to keeping the knee joints young? What is the best way to exercise the knee joint in a healthy way? Is it advisable to climb a mountain for exercise? Is it really beneficial to abandon the elevator and climb more than 10 floors? Today, talk to you about the misconceptions of the elderly knee exercise, in the end how to exercise the knee is the right. 1, weight control The knee joint carries the weight of the upper body, the more weight the knee joint bears, the greater the chance of wear and tear of the articular cartilage, the knee joint degenerates faster. If you are overweight, you must lose weight, weight loss is very important to protect the knee joint, otherwise, your knee joint will “age” faster than others. 2, avoid climbing hills climbing hills is a very good way to exercise, but, for the elderly, but not a good way to exercise, because climbing hills is very “wear and tear” on the knee joint. When climbing, the knee joint has to support the weight of the whole body with one knee, and when descending, the knee joint has to fight against the downward force, so the whole process, the knee joint joint surface friction is serious, so it will aggravate the degeneration of the knee joint. 3, do not climb the stairs Many people at home, there are elevators do not sit, deliberately climb the stairs to exercise, do not know, climbing the stairs this exercise although you can exercise cardiorespiratory function, but, the wear and tear on the knee joint is also very large, climbing the stairs and climbing the same, is also not recommended exercise. 4, avoid repeated deep squatting exercise do not know from geometry, in the park we will see a lot of grandparents hands on their heads, repeatedly squatting stand up, this exercise, for the knee joint has not degenerated young people, can be a good exercise for the lower limb muscles, is a good exercise, but for the elderly, their knee joints are degenerative changes, the joint surface are “Potholes” are not smooth, continue to repeatedly squat exercise, can further aggravate the wear and tear. 5, knee pads really protect protect your knee joint? Not that knee pads can really protect the knee joint, for knee injuries, knee instability friends, knee pads can further stabilize the knee joint, but for older friends of the knee joint, we do not recommend wearing knee pads, because knee pads are equivalent to adding a force to the patella, further increasing the friction between the patella and the femur. 6. “Dangerous” high heels Many older women love to wear high heels. When wearing high heels up and down steps, the force on the knee joint is much greater than normal, making it easier to increase wear and tear on the knee joint. 7, walking, the best exercise for the elderly Walking is a relatively mild form of exercise. 8, swimming Swimming can not only exercise muscle strength and coordination, while not increasing the load on the knee joint, is a very good way to exercise, for the general health of the elderly is a good choice. The knee joint is like the tires of a car, it has a certain life span, so we have to love and save it, not just exercise certain parts of the body and aggravate the wear and tear of the knee joint.
