On each side of the human torsoThe oblique muscles of the press, which perform the functions associated with the rotation of the body. Skewed abdominal muscles are divided into internal and external. The internal ones are quite deep, passing from the pelvis to the sternum, and above them are located the external muscles, just under the skin. They help to twist and bend the case. When curling to the left, the left outer and right inner muscles are involved, and when twisting to the right, vice versa. The oblique muscles of the press together with the transverse muscle of the abdominal cavity perform the functions of stabilizing the spine, increasing intra-abdominal pressure. Thus, a healthy functioning of the spine and maintaining the correct position of the internal organs is achieved.
Outer oblique abdominal muscles are the mostthe largest and most prominent of all abdominal muscles. They are used for cornering or tilting forward, and also they help when lifting or carrying heavy objects. In addition, these muscles are the only of the abdominal muscles that are in constant activity while standing. They help to support the body in an upright position, not allowing the force of gravity to affect the balance of a person. They also support the lower back and spine during various movements.
The outer oblique muscles of the press on the outerthe surface in the lower ribs, where it has large teeth, the five upper ones are located in the anterior dentate muscle, and the three lower ones are in contact with the teeth that are part of the latticed muscles of the back. The upper muscle beams are formed near the cartilage of the ribsand pass in the horizontal direction. The bundles located below pass obliquely from top to bottom. And the lowest beams are directed vertically downwards. All muscle beams in front of the edge of the rectus muscle become aponeurosis.
Blood supply to the external oblique muscles is provided by the posterior intercostal arteries, the superficial artery that surrounds the iliac bone, and also the lateral thoracic artery.
The internal oblique muscles of the press are designed forflexion of the spine with their bilateral reduction. In the case of unilateral reduction, these muscles, together with the external oblique muscles, help to turn the body and lower the ribs.
The internal oblique muscle originates fromintermediate line on the iliac crest, lumbosacral fascia, and also on the lateral part in the inguinal ligament. The fiber bundles of the upper part of this muscle are attached to the cartilages located on the lower ribs and extend from the bottom upwards. And the lower tufts, directed both upward and downward, develop into a wide aponeurosis along a contour drawn to the pubic bone from the cartilage X located on the rib. The lower tufts of this muscle also belong to the spermatic cord, due to which a muscle is formed, responsible for raising the testicle.
Blood supply to the internal oblique muscles is provided by the muscular-diaphragm artery, the upper and lower epigastric arteries, and the posterior intercostal arteries.
The oblique muscles of the press, as well as the lumbar muscles,belong to the muscles of stabilizers. Strengthening these muscles will allow you to maintain a beautiful posture and ensure a healthy functioning of the spine. Any complex movements of the trunk begin, first of all, with the contraction of the abdominal muscles. Only after this activity is transferred to other muscle groups. Therefore, it is necessary to pay due attention to the performance of exercises to maintain the tone of the muscles of the press, since otherwise there may be an imbalance in the development of muscles or asymmetry in the waist. When doing exercises for the press, we should not forget that to achieve a beautiful embossed press, the fat layer should not exceed 1.5 cm, so training should be aimed at both hypertrophy of the muscles and reduction of subcutaneous fat cells.
