What causes the knees to be weak when walking? Doctors teach you how to cope
The knee is the largest and most complex joint in the human body, and its existence ensures many basic functions of the human body, such as walking. However, with the increase of age, the joint parts of the human body are prone to aging, and the knee joint is the most likely to be "shot". Many middle-aged and elderly people report that when people get older, their knees tend to become weak and sore after just walking a few steps. What's the matter?
What causes the knees to be weak when walking?
- Soft knees tend to occur in middle-aged and elderly people, because the body functions of this age group will degenerate accordingly. For example, the decomposition rate of bone cells gradually exceeds its synthesis rate, the interior of the bones gradually becomes empty, the bone fragility increases and the bone toughness weakens. The joints are no longer hard and are prone to softening.
At the same time, the body metabolism and absorption capacity of the middle-aged and the elderly is far less than that of the young. The calcium loss in the body of the middle-aged and the elderly is fast. In addition, the absorption of calcium intake is difficult, and the bones are prone to calcium deficiency. When the knee becomes weak and weak.
- Knee weakness is not a "patent" for middle-aged and elderly people, and young people may also experience this symptom. Calcium deficiency is also one of the reasons. Since the body of the younger generation is in the developmental stage, the demand for calcium is relatively large. If the calcium intake is insufficient, the bones tend to soften and the knees become weak.
For knee weakness caused by calcium deficiency, calcium supplementation can be relieved. At the same time, knee weakness in young people may also be related to exercise. If you usually like to do some exercises that put a heavy load on the knee, such as sprinting, weight-bearing squat, etc., and the exercise intensity is not reasonably controlled, the soft tissue around the knee joint may be excessively worn and softened.
- Knee weakness may also be related to the lack of warm measures in the joints. When the seasons change, the huge temperature difference will stimulate the human body and cause muscles and blood vessels to contract, resulting in poor blood flow.
In addition, if the joints are exposed to cold for a long time, the long-term effect of cold stimulation will also affect the local blood circulation, thereby causing joint pain and weakness. For joint weakness caused by cold, it can be improved by increasing warmth measures, such as wearing knee pads, adding clothing, hot compresses, etc., and avoiding long-term living in cold environments, which can effectively protect the joints.
The health of the knee joint is an important basis for the normal activities of the body. Therefore, the maintenance of the knee joint should not be neglected. On weekdays, it is necessary to do a good job of preventing cold and keeping warm at the joint, reasonably ingest high-calcium food, and cooperate with physical exercise to strengthen bones and reduce weight. slow degradation.
