Besides running, the long jump will also hurt our knees! Long jump can be divided into assisted long jump and standing long jump, and the injury of assisted long jump is more serious. Before the power-assisted long jump, athletes need to sprint for a short distance, and then take off with the help of running inertia, but most people don't know that this running inertia is difficult to ease after landing, and the inertia will be scattered to the knees, causing serious damage to the knees!
The same is true of the standing long jump. There is a force from the ground to the center of gravity when standing long jump falls to the ground, and it will hurt your knees with the bending of your knees after landing! Many people will feel a pain in their knees after standing long jump, which is actually caused by this reason! In addition to long jump, running in situ is also a kind of exercise that hurts the knee, but the injury of this sport is ignored by most people!
The frequency of running fast in situ is very fast, and the time left for power buffering is very short. If the force can't be buffered, it will be transferred to the leg, and the knee is also a part of the force transmission, because when running fast, the knee keeps bending, straightening and repeating, which leads to the force can't be dispersed, which will have a certain impact on the knee!
In fact, a lot of exercise will cause damage to the knee, but if we can consciously prepare, warm up and rest properly during the exercise, we can avoid the damage to the knee!
