What causes knee pain? What causes knee pain after exercise?

Many people experience knee pain after exercise. What is going on? This means that we have not exercised for a long time. Suddenly, a lot of exercise will lead to this phenomenon. Another reason is that the exercise posture is incorrect, and the warm-up exercises before exercise are not done well.

1. Long-term inactivity leads to sudden exercise or even high-intensity training without a buffer period. The knee joints suddenly bear a much heavier load than usual and cannot adapt to it for a while, so it is easy to feel soreness after exercise.

2. Incorrect exercise posture . When exercising, the posture used is not correct. For example, if the running posture is incorrect, it will cause greater wear and tear on the knee cartilage, causing the knee joint to bear greater pressure, thus causing knee pain during exercise.

3. Insufficient warm-up exercises. If you do not do warm-up exercises or do them insufficiently, and start exercising without warming up your joints and muscles, it is easy to sprain the knee ligaments and experience knee pain. In addition, if you do not warm up sufficiently, the knee joint will not be able to secrete enough lubricating ingredients, resulting in severe wear and tear of the knee during exercise, which will aggravate the knee pain.

4. Inappropriate shoes. When exercising, if you wear high heels, slippers or other shoes that are not suitable for sports, it will increase the pressure on the knee joint, which can easily cause knee joint injury and pain.

5. After strenuous exercise that causes lactic acid , a large amount of lactic acid will be produced in the body. If lactic acid cannot be broken down in time in the body, muscle soreness will occur, and knee pain will easily occur.

6. Excessive exercise and long-term high-intensity exercise, if it exceeds the load range of the body's muscles and joints, can easily cause damage to the body's joints and muscles, and may also cause knee pain.
