The so-called "core" is the middle link of the human body, that is, the area below the shoulder joint and above the hip joint, including the pelvis. It is a whole composed of waist, pelvis and hip joint, and contains 29 muscles.
Core muscle group is responsible for stabilizing the center of gravity and transmitting strength, which is the main link of the overall force, and plays an important role in the activity and force of upper and lower limbs.
Strong core muscle groups play a stabilizing and supporting role in body posture, sports skills and special technical movements in sports. Therefore, anyone with graceful posture, strong body control and balance ability must train the core muscle groups well.
Core muscles refer to the muscles around our trunk, including abdominal muscles, gluteal muscles, and muscles connected with the spine and pelvis. When our hands and legs move, these core muscles will help our body to keep stable and upright. Others call these muscles "the home of power".
Because the whole human body is arranged like a sports chain, and the core part connects the upper and lower parts of the human body, just like a bridge. If this "bridge" goes wrong, it is likely to cause problems in the upper/lower body and even the whole sports chain.
There are two parts of the core muscles that need special attention. One of them is the transverse abdominal muscle: it is the deepest of the four abdominal muscles, and its muscle fibers are transverse, so when it contracts, it compresses the internal organs like a belt to support the back.
Strong transverse abdominis plays a very important role in preventing back injury and improving sports table. There is a good way to know where the abdominal muscles are deep. When laughing, the part where the lower abdomen contracts inward and vibrates is the transverse abdominal muscle. To contract the transverse abdominis muscle, you can imagine pushing the navel to the spine and pulling it inward.
In addition, the muscles in the core and the muscles in the pelvic floor are very important. These muscles are connected to the pelvic floor and consist of multiple layers of muscles. When these muscles are tightened, the pressure in the abdomen can be increased and the transverse abdominis muscle can be contracted, thus stabilizing the body.
Tightening these muscles feels like going to the toilet, but you can't help it. You can imagine that the muscles at the bottom of the pelvis are like an elevator, rising from the first floor to the second floor and then to the third floor, and then slowly descending layer by layer and returning to the first floor. Through this imagination, you can effectively practice tightening these muscles.
