Eight common wrong running postures
Cross swing arm
Cross-chest swing arm, also known as left and right swing arm, is one of the most common wrong swing arm movements. This will lead to excessive twisting of the body, unable to balance the body, increasing strength, leading to a decline in running efficiency, and even the risk of knee injury in lower limbs.
Run with your head up.
Holding your head too high won't make you look more handsome or breathe more smoothly. On the contrary, it will make your back muscles tense and your center of gravity move backwards. The center of gravity is located at the back, which is equivalent to wasting the braking force. Running is very laborious, which puts unnecessary pressure on your knees.
Sit and run
Just like low-headed people running with their heads down, sedentary people tend to sit and run. Sitting and running means that when running, the back pedal and back extension are insufficient, the legs are in front of the body center of gravity, and the whole body is relaxed and sinking, which looks like "sitting and running". Sitting and running for a long time will increase the pressure on the spine, because the pelvis leans forward too much and causes low back pain; At the same time, insufficient pedaling and stretching can't generate enough forward power, and the running efficiency is low.
Humpback running with chest.
People who work at their desks for a long time and bow their heads to play with their mobile phones can easily bring the habit of running with their heads down. Running with head down will greatly increase the pressure on the cervical spine, and it is easy to cause shoulder and neck discomfort and pain after running. At the same time, hunchback will affect the smooth breathing and the stability of the trunk, thus reducing the overall running efficiency.
Waibazibao
People who usually walk outside the eight characters should pay attention to whether they run outside the eight characters. The main reasons for running the external figure-eight are insufficient core strength and tense leg muscles, or it may be the external figure-eight step caused by congenital external rotation of the calf. Running outside the figure of eight will lead to abnormal stress on the ankle, calf and knee joint, and increase the risk of knee joint and ankle joint injury.
Knee hyperextension
This kind of running posture is common and harmful. Knee hyperextension means that when landing, the knee flexion angle is too small, the knee is straight, and the landing site is too far in front of the body center of gravity. At the same time, the foot follows the ground, so it is easy to transfer the ground force directly to the knee without buffering, resulting in excessive stress on the knee, which will lead to knee pain in the long run.
Stride
Walking is easy to understand, that is, every step is like a step, with large stride and low step frequency. Stepping means that the greater the fluctuation of the center of gravity, the more energy is consumed; At the same time, striding can easily lead to knee hyperextension, and it can also lead to knee injury because of the excessive impact on the knee when landing.
