Regular running will definitely damage the knee joint, so you must have a correct running posture, which will minimize the damage to the knee joint. The occurrence of overwork injury is the result of repeated overload. Simple one-time overload is not enough to cause irreversible deformation. When the load accumulates for a period of time and exceeds the damage threshold of tissue, overuse damage will occur.

In the runner group, about 50%-70% of running injuries show overuse injuries. Common knee injuries mainly include patellofemoral joint syndrome, iliotibial tract syndrome, patellar tendinitis, bursitis and so on.

Extended data:

The internal organs and limbs of the human body need an adaptation process from a relatively static state to a relatively tense activity. Therefore, people should also do proper preparatory activities before running, so that the physiological functions of the body can coordinate their work under the condition of exercise. If you don't do warm-up activities before running, joint ligaments and tendons will often be sprained during long-distance running. It is more likely to happen especially when running nervously together. Before running, you can generally do the following warm-up activities:

(1) Stand with your hands akimbo and move your ankles alternately;

(2) Squat down and move your knees with your hands;

(3) Lift the legs alternately to move the hip joint;

(4) Turn the waist with your hands akimbo and move the waist;

(5) One-handed support, kicking back and forth in turn to move the hips and knees;

(6) lunge and lunge leg press; Left and right leg compression, involving leg ligaments;

(7) The upper body bends back and forth, and the upper limbs move slightly.

Only the correct posture can make you run fast, efficiently and not easily injured. One of the keys to burning fat is running at an intensity close to your anaerobic limit (anaerobic threshold). The correct posture can enable you to reach this intensity without wasting extra energy.
