How to maintain your knees?
1, the life span of male and female knees is different: due to the different constitutions of men and women, the life span of knee joints is also different, and female knees are relatively weak. Because the physiological process between men and women is very different, women have to go through childbirth, menopause and so on, so there will be some damage to the knee joint. After women are 30 years old, at this time, the bone density will drop, so there will be some discomfort in the knee joint. Men will also feel uncomfortable during this period.
When a woman reaches the age of 50, her menstruation will stop, so this is what we often call menopause. At this time, the bone density will drop and the knee joint will become more and more fragile. When a man is about 60 years old, his knee joint will also be traumatized. Therefore, in daily life, he must take care of his knee joint to avoid mobility inconvenience in old age.
2, choose the right exercise, get twice the result with half the effort: when we flex and stretch the joint, don't keep an action for a long time, it is easy to damage the knee joint. The best state of the knee joint is about 20 years old, so keeping the weight of 20 years old is excellent for the knee joint and can slow down the aging of the knee joint. There is another important point. When we were young, we exercised our knees healthily, so as we get older, it won't have much influence on our knees. However, not exercising often and doing a lot of activities after getting old is fatal to the knee joint. Therefore, with the increase of age, we should choose weightless exercise, which will not bring too much damage to the knee joint. For climbing mountains, squatting and other sports, you should be moderate.
3, calcium supplementation helps to protect joints: the key to bone health lies in calcium in the body. If you lack calcium, your bones will not be healthy. So many people will pay attention to calcium supplementation. For young people, the best way to supplement calcium is through diet and some sunshine. In fact, forcibly supplementing calcium is not good for your health. Because when we get old, all the organs of our body are declining, and the digestion and absorption function of our stomach is also declining. We can only supplement calcium through external force.
For us, the bones of the knee joint can not be separated from the muscles of the leg, so the muscles of the leg are stronger, which can give the knee joint a good support, so we can often carry out straight leg lifts to exercise the strength of the leg.
