As we all know, the correct posture is important for the health of bones and muscles, but how many people can maintain a good posture every day in daily life and work? The bad posture of the yearly will cause the bones and muscles of the body to be produced. Cross-syndrome is one of a variety of poor adaptive changes. Cross syndrome is a symptom in which the body posture deviates from normal. "Crossing" refers to the arrangement of the strong and weak muscles that cause the deviation of the posture: "syndrome" means that the posture of the deviation has various characteristics. The cross syndrome is divided into an upper cross syndrome and a lower cross syndrome.
The physical characteristics of the upper cross syndrome are round shoulders and head forwards (forward exploration). This posture is mainly caused by some muscle imbalance in the body. Some muscles are strong and tense, such as the pectoralis major, the pectoralis minor muscle, the scapula levator muscle, and the trapezius muscle bundle; some are weak, such as the rhomboid muscle, the trapezius mid-lower bundle, and the deep cervical flexor. This symptom often occurs in bodybuilders who have been working with computers for a long time and who have overtrained chest muscles without stretching exercises. So what is wrong with this symptom? It not only affects the body shape, but also causes muscle tension in the neck, shoulder and neck pain, severe increase in cervical pressure, compression of the nerve between the cervical vertebrae, leading to headache and arm paralysis; round shoulders It will affect the range of shoulder joint activity, and it is easy to be injured when training shoulder muscles. If it is long-term, it will lead to a decrease in the volume of the chest and abdomen, which will make the breathing unobstructed.
The physical characteristics of the lower cross syndrome are obvious anterior tilt of the pelvis and excessive anterior curvature of the lumbar spine. Those middle-aged men with beer belly, pregnant women, and women wearing high-heeled shoes often have such a posture. These people adjust their body center of gravity and maintain their balance, so they adjust by pelvic forward and increase the curvature of the lumbar forward. In the end, it formed a posture of “before and afterwardsâ€. This long-term posture can lead to muscle imbalance and the formation of muscle strength changes in the intersection. Strong, tense muscles are: iliopsoas, erector spinae; weaker, relaxed muscles are abdominal muscles, gluteus maximus. If you are often in a pelvic anteversion and excessive lumbar spine, it will increase the pressure on the lumbar vertebrae. In particular, the soft tissue around the lumbar vertebrae and the first humerus in Section 5 is stressed, which may cause lower back pain; affecting the dynamics of hip extension. Posture; at the same time, because of changes in the center of gravity, it may cause over-extension of the knee joint and increase joint pressure.
It can be seen that whether it is the upper cross syndrome or the lower cross syndrome, they not only directly affect our body shape, but also damage the health of our bones and muscles. Therefore, in addition to maintaining a good body posture in daily life, it is also necessary to properly stretch the tight muscles and strengthen the weaker muscles in order to effectively avoid the cross syndrome.
