In addition to strenuous exercise, you should also pay attention to the following behaviors that hurt your knees the most:
First, sedentary. Sedentary has become the norm for many office workers and student parties. When this behavior is maintained for a long time, it will lead to the gradual deterioration of knee joint function, and when it is carried out suddenly and violently, it will lead to knee joint injury.
Second, climb the stairs with heavy load. Going up and down the stairs will affect the knee joint, especially going down the stairs. It mainly depends on the contraction of quadriceps femoris to pull the knee along the femur, which will seriously wear the knee joint for a long time.
Third, jump rope. Skipping rope puts a lot of pressure on our knees. When skipping rope on the concrete floor, the ground is hard, which requires a large reaction force and hurts joints and bones. Therefore, it is recommended to choose shoes with strong cushioning ability or shoes on plastic track.
Fourth, ignore warm-up exercises. Some people ignore the warm-up exercise before exercise and go straight into strenuous exercise, which is particularly easy to cause bone and muscle damage. I suggest you warm up before exercise. In fact, it can not only protect the knee joint, but also lubricate the knee joint well, improve muscle elasticity and not hurt the knee.
In addition, it is recommended that you exercise moderately to avoid excessive exercise or sudden strenuous exercise, so that our knees will bear the pressure of overload, which will not only easily cause injury, but also increase the internal friction of the knees and hurt them. In addition, it is necessary to enhance the awareness of protection and avoid violent collision of knees to avoid injury.
