The hip flexors tend to shorten and can be the trigger for back pain. Whether the pelvis can be fully erected or not depends on the length, strength, and elasticity of our hip muscles. The hip joints are located in the pelvic blades and are responsible for the position of the pelvis.
When we stand, there should be a balance of power between the anterior hip muscles that bend the hip joints and the back-hip muscles that stretch the hip joints. The front hip muscles, the hip flexors, are a bit degenerate in modern humans because of our habit of sitting for long periods of the day.
The original hunter-gatherer, who was on his feet most of the day, has become a permanent owner. This has led most of us to get used to the hip flexors to the seated position, thereby gaining the upper hand. The hip joints are in the diffraction of almost 90 ° all the time.
Over time, this causes the hip extensors, mainly the glutes, to slacken and have little strength and tension, and the hip flexors contract, contract and develop an unnaturally high resting tension.
According to this website, the body always tries to adapt to external conditions, and if we spend the whole day sitting, it regulates the voltage and length ratios according to this relatively new posture.
Shortened hip flexors lead to poor posture and back pain
Once the body has adjusted the muscular balance of power between hip flexors and hip extensors to the sitting posture, we can sit and save economically and economically, that is the meaning of the whole.
Problems only arise when we get up from sitting and stand again. Then the hip flexors and hip extensors are still optimized for the sedentary posture and no longer for our original, natural posture, the upright stance. As a result, the flexion of the hip joints is fixed up to a certain angle of movement, as the hip flexors by the permanent sitting on set a new normal length of about 90 °.
The slack hip extensors are thus more than twice as hard to counter gravity, to fully stretch the hip joints in the stance and straighten the pelvis and keep it permanently in that position. It inevitably comes to bad postures that usually creep in very unconsciously, and we get used to imperceptibly.
Since we can’t fully raise our pelvis, but still hold the torso and the upper body in the vertical position, it inevitably leads to an overstretching of the lumbar and cervical spine. We focus more and more on the lower back, resulting in extreme hollow posture and permanent overstressing of the lower back, lumbar spine, and intervertebral discs.
The same thing happens in the area of the cervical spine, here too we get used to hyperextension, and it also comes here to overload.
