Why are old legs old?Knowing these five truths and "knee"

Our knee joint is the largest joint of the human body. When we walk flat, go up and down, and squat up, the knee joints are playing a role. The flexion and extension of the knee joint is a key factor in completing the above action.

Each of our knee joints will have symptoms of pain symptoms earlier than other joints. By the age of 50, the knee joint is more or less painful, and even some people are less than 50 years old, and they have knee pain. Just cater to the old saying: "People are old -legged first."

Why is such an important joint more prone to aging? If we know the reason, we can maintain the knee joint targeted and prevent the occurrence of aging arthritis.

Truth 1:

Use more exercise to control the amount

Every movement of humans is inseparable from the knee joint. Walking, running, jumping, squatting, the role of the knee joint is essential. Generally normal people, the number of steps required for daily life is about 10,000 steps, and the number of steps is not counted. Therefore, the knee joint is already worked hard under normal use. If there are additional exercise and a certain range of strong fitness, you will accelerate the aging of the joints once it is too much.

Every day, the knee joints must be flexed and extended at least and extended more than 10,000 times under weight. Coupled with the flexion and extension of the knee joint when sitting and bed bed, the number of flexion and extension of the knee joint should be about 20,000 times.

The knee joint is so "hard", then people who love sports, those who want to exercise their physique, those who want to exercise to lose weight, and people who want to exercise to control blood sugar should control the amount of exercise. As for accelerating the aging of the knee joint?

Maintenance plan

The principle of our exercise is that it varies from person to person and varies from time to time; gradually increases, and it can stop. not

Each life has different constitutions, motion tissues such as bones, joints, tendons, muscles, and the strong degree of strong cardiopulmonary system. The amount of exercise that can be tolerated is naturally different, and everyone cannot be measured by the same exercise standards. How to master the amount of exercise? Mainly rely on everyone's own feelings.

Every kind of exercise can be performed. There is no discomfort in the body during exercise. There is no pain in each part of the body after exercise. It can have a sense of mild fatigue. The next day there is no feeling of overer fatigue and resting. At this time suitable. With the increase of physical fitness, the amount of exercise can gradually increase. After the increase, the pain and fatigue can be relieved quickly, that is, we can bear the amount of exercise that is good for health.

Truth 2:

Large control weight weight reduction is to reduce the burden on it

Among the four major joints of the shoulder, elbows, hip and knees, the knee joints are at a low level, so the weight of the knee joint is the largest of these four joints.

The shoulder joint and elbow joints are located on the upper limbs. Except for the weight of the upper limbs, the upper limb joint degeneration is relatively late, and the degree of wear of the joints of the joint surface is also light. However, the difference between the knee joint is a typical loading joint. It can be said that bearing the main task of the knee joint. In particular, not only should we bear weight but also move. For example, when squatting, the quadriceps muscle contracted strongly, pulling the tendon, and then pressing the bone, resulting in the joint surface between the bone and the femur. load.

Similarly, when we go up and down the stairs, the joint cartilage between the bone and the femur also undergone tremendous pressure. When going down the stairs, the joint cartilage between the femur and the tibia must also withstand the impact of the physical decline, that is, the weight plus the impact, so the damage to the joint when going downstairs is greater.

Maintenance plan

Since the position determines the weight of the knee joint, what we can do is control our weight. not

Fat people, that is, a heavy person, will inevitably increase the joint load. Conversely, if you want to reduce the load of the knee joint, you must reduce weight. Control the weight within the normal range, the knee joint does not have additional load, and the aging speed will slow down. not

However, it should be noted that there is no need to lose weight for people with normal weight. Because the less weight is, the better, and the weight is too light, which will also affect the intensity and stability of the joints.

For example, people with too light weight are prone to osteoporosis, so the joints composed of bones as the main component are inevitable. Specific to the knee joint, osteoporosis will lead to the decrease in the lower bone of the inner tibial platform. For example, the foundation of the house is not firm, and the cartilage of the surface of the cartilage surface will be uneven, which will cause the cartilage degeneration to advance in advance.

Truth three:

Complex structure Avoid trauma and affect joint firmness

The structure of the knee joint is complicated, and it consists of three parts: distant femoral end, tibia near -end, and cymbal bone. Top tibia joints. There is a half -moon plate between the tibia and the femoral bone. It is a fiber cartilage pad. The role is to increase the contact area between the tibia and the femur during the activity, stabilize the joints and disperse the stress, and reduce the impact. The exquisite cooperation of the two maintains the stability in the process of knee flexion and extension. If these two ligaments are damaged or even broken, the knee joints will be unstable and accelerate the aging of joint wear. The far -end of the bones connects the tendon tendon and the four -headed tendon, respectively, and the inner and outer collateral ligaments on both sides of the knee joint. The above structures have an insufficient damage or degeneration intensity, which will affect the stability of the knee joint, and then accelerate joint aging.

Maintenance plan

This cannot be changed. All we can do is to avoid knee trauma. not

Once the injury is difficult to repair due to its complex structural repair, it is impossible to completely repair it, which will inevitably lead to the decrease in the stability of the joint, and the aging of joint aging will inevitably accelerate.

If you are injured, you need to fully recover and try to maximize the joints as possible, otherwise it is more difficult to deal with after symptoms.

Truth 4:

Pay attention to keep warm

The state of the knee joint can not be used to use "skinny", and there is no muscle protection around it. Because there is no muscle around the knee joint, the thickness of the structure of the skin, ligament and joint capsule is less thick, the knee joint is easily cold.

The blood vessels shrink after cooling will inevitably lead to a decrease in blood flow, resulting in insufficient joint support for joints and surrounding structures. After joint wear, you cannot perform metabolic repair in time, which will cause joint cartilage to wear easily and synovial edema inflammation. Over time, the irreversible damage of the knee joint is formed.

Some people say that European and American people, Russians, and Japanese have no habit of wearing autumn pants, and their knee joints are not bad? In fact, there are some controversy in the horizontal comparison. The racial physique of Europeans and Russians is very different from us, and they are more tolerated. Perhaps this can adapt to the cold early, and their knee blood vessels also adapt to work in the cold situation without being shrinking cold.

Maintenance plan

The knee joints of our people cannot tolerate the cold, so we must pay attention to keep warm, especially, as the joints are aging, it needs to keep warm. not

This is actually the easiest link in joint maintenance.

Truth five:

Joint cartilage cannot be regenerated and prevented in time.

The joint cartilage in the knee joint is under tremendous pressure, impact, friction, unstable, sloganitis, and poor nutrition will affect the integrity of the cartilage. Over time, the cartilage will crack, remove, and lack. Can't regenerate.

Maintenance plan

The best way is to prevent joint cartilage damage or strengthen joint cartilage. not

At present, there are drugs with joint cartilage components, such as amino glucose, chondroitin sulfate, and angle quality of sulfate. The joint cartilage is still in health or mild damage. It has a certain repair effect. This repair effect is limited and varies from person to person.
