What is core muscle group? Large decoding of core muscle group

Many people who have just come into contact with sports will be reminded to "must exercise the core muscles, but what is the core?

Today we will come with you briefly and clearly.

　　I was surprised when I first came into contact with the core muscles! Why are there a lower back core, abdomen core, and a hand core? Does the body need to provide cores like a computer? It can also be divided into broad and narrow meanings? It makes me confused!

What is the core?

　　The core generally refers to multiple muscle groups attached to the spine, which are collectively called core muscle groups, referred to as "core". These muscles protect and stabilize the spine, so that people will not be hurt when bowing, stretching and other "any action".

　　According to the book "NASM Essential Personal Fitness Training", the core can be divided into three parts:

     Local core stabilization muscles

　　Refers to muscles directly attached to the spine

          Comprehensive core stabilization muscles

　　Refers to the part that is attached to the pelvis to the spine

            Movement system

　　Including muscles attached to the spine/pelvis to the limbs

Where is the core? 　　The core muscles are composed of abdominal transverse muscles, multifissure muscles, internal oblique muscles, and square lumbar muscles. When comparing the surface rectus abdomen, external oblique muscles, pelvic floor muscles and other muscles, the position of these muscles is approximately below the diaphragm to the pelvic floor. Simply put, below the chest to above the buttock, and surround the entire torso with the spine as the center.

　　For use, the chest, shoulders, and buttocks are not against the core muscles, so there is naturally no problem with the three cores and four cores.
