Performance of bad posture
Cross your legs: Many people habitually cross their legs after sitting down. Maintaining this posture for a long time will have many adverse effects, such as patellofemoral arthritis, nerve compression of lower limbs, local blood pressure increase and varicose veins. In severe cases, the stress on both sides of the spine will be unbalanced, leading to scoliosis, spinal nerve compression, low back pain, muscle strain and bone lesions.
Eight-legged legs: the thighs and knees are close together, the feet are separated by a certain distance, and the calves form a figure of eight. This kind of sitting posture looks more ladylike, but it can also effectively avoid exposure, but it is not healthy, especially easy to make the crotch expand laterally, resulting in the phenomenon of false crotch width.
Round legs: thighs are separated from knees, calves cross and ankles overlap. This kind of sitting posture not only looks elegant and dignified, but also puts the weight of the body on the crotch like a splayed leg, which is easy to cause excessive pressure on the hip joint and the phenomenon of false hip breadth.
Neck probing: According to medical standards, if the curvature of the neck exceeds 5 cm, it will be considered as a problem of neck probing. In daily life, if in a natural state, the head stretches forward and the chin rises slightly, you need to pay attention. Nowadays, there are more and more "low-headed people", and neck probing has become the most common posture problem.
Round shoulder: from the side of human body, under normal standards, ears, shoulders, hips and heels should be in a straight line. If the shoulders are not in this straight line, but offset to the chest, this is a round shoulder. Round shoulders, also known as chest-containing, often lead to hunchback and thoracic vertebra deformation.
Humpback: working or studying at a desk for a long time will make people bend over unconsciously, and over time it will cause kyphosis of the thoracic spine and deformation of the spine, that is, hunchback. Physiologically, the main manifestation is that the curvature of thoracic vertebra becomes larger or the curvature of lumbar vertebra becomes straight, and the former is generally common. This kind of bone deformation will cause the stiffness and spasm of the surrounding tissues, and the back will lose its elasticity and vitality, thus affecting normal life behavior.
Pelvis retroversion. Pelvic anteversion: Under normal circumstances, the pelvic position should be in a neutral position, and the pelvic anteversion and anteversion are tilt changes relative to the neutral position. When standing against the wall, keep the back of your head, shoulders and heels close to the wall. If the distance between the back and the wall is the thickness of a palm, the pelvis is in a normal neutral position. If there is no gap between the two, it may be pelvic inclination; If the distance between them is as big as a fist, or even bigger, then it may be that the pelvis is leaning forward.
Pelvic recession is generally caused by long-term bad sitting posture, which will eventually lead to the flattening of lumbar curvature, ugly posture such as hunchback, hip drooping and fat accumulation in the lower abdomen, as well as chest tightness, shortness of breath, neck and shoulder pain, endocrine disorders and other symptoms. This phenomenon is also common in people who exercise excessively. Overloaded training makes the muscles of the back and front thighs well developed, while the abdomen and back thighs are relatively weak, showing a "bodybuilding waist" shape with large hips and upper body moving forward, which is actually not a healthy shape.
