Core anatomy

　　It is often heard that core muscle training is very important for the human body. In various movements and even exercises, it stabilizes the proximal limbs such as the spine and pelvis, provides distal mobility, and ensures strength transmission

　　But what does core muscle mean? Is it a beautiful six-pack abs?

　　Look at the anatomy of the core muscles

　　Simple, the core includes the spine, ligament, fascia and nearby muscles

　　The muscle part is like the abdominal muscles in the front, the diaphragm above, the muscles and gluteal muscles next to the back, as well as the pelvic floor and hip joint at the bottom.

　　The following will count the parts related to the core.

　　Take the lumbar spine as an example

　The posterior side of the spine includes facet joints, pedicles, laminars, and pedicle isthmus (pars) Interarticularis) and intervertebral disc.

These tissues are actually soft and can withstand some forces, but if there is too much external force, such as poor muscle control, it may cause structural problems, such as intervertebral disc herniation. The ligaments of the spine do not provide much stability, and their more common functions are to perform lumbar sensation afferent.

　　The thoracolumbar fascia

　　The posterior layer plays a very important role in supporting the lumbar vertebral and abdominal muscles. The transverse abdominal muscles are quite wide in the middle and posterior layers. The posterior layer of the thoracolumbar fascia is further divided into two layers: the shallow layer down to the mesh, the deep layer down to the bottom and out.

　　The aponeurosis of the lats dorsiformis forms a shallow layer, so the thoracolumbar fascia plays the function of connecting the upper and lower limbs.

　　　The stratospinal muscles (paraspinals)

The main ones are erector spinal muscles and local muscle groups, including the rotating muscles, transverse interstitial muscles and polyfiscis muscles.

Taking the lumbar spinal spinal muscles as an example, the erector spinal muscles are mainly the longest muscles and iliocurs muscles.

The local muscle groups mainly provide intervertebral stability, not responsible for the production of movements.

　　　　　　　　　　The lumbar muscles are mainly used to provide intervertebral stability, not responsible for the production of movements.

　　　　The lumbar muscles are The largest and most superficial muscles perform centrifugal contraction control when the lumbar spine is straightened and rotated. The rectus abdominal muscle is mainly the lumbar flexor.

　　Hip muscle group

　　In all walking activities, provide stability of the trunk and pelvic pelvic, and return the strength of the lower limbs to the trunk.

　　Although the lumbar muscle is the hip flexor, it has three proximal continuity points: the transverse process of the twelfth thoracic vertebra to the fifth lumbar vertebra, intervertebral disc and vertebra.

　　　　The transverse diaphragm and pelvic floor muscle

Taking the lumbar spine as an example, the stability of the lumbar spine is related to the contraction of the diaphragm and the increase in abdominal pressure. Some literature points out that cases of recommending iliac joints have problems in the diaphragm and pelvic floor muscle.

　　The Stability is also very important. 　　In the past, core training focused on the transverse abdominal muscle and polyfisted muscle to avoid excessive use of rectus abdominal muscle. But later I found that there were many things that needed to be considered, including parts like the transverse diaphragm, so professional personnel needed to evaluate each part and provide suitable exercise and training.

　　Last tip: After reading the above introduction, you should know that the core muscle does not refer to a single individual such as a certain piece or a few muscle groups! It is a huge system. These muscle groups work together to maintain the stability of our spine and ensure the transmission of strength. It is a cooperative ability, which is what we often call core strength!

　　So: It is not to strengthen a certain core muscle (such as rectus abdominal muscle) alone to train core strength. What you should train is a ability!
