What is the role of the pectoral muscles, and what is the role of the developed pectoral muscles?

What does your question have to do with the pectoral muscles......

Exercise more, play basketball, play soccer or something, don't feel inferior, it's not a shame.

The benefits of men's pectoral muscles: 1. Make the pectoral muscles developed and elastic, which can better protect the internal organs and ribs of the chest cavity. 2. The chest muscles are developed and shaped, and the dressing is better, which enhances the temperament and charm of men.

3. Improve cardiopulmonary function, increase lung capacity, increase the amount of blood pumped by the heart each time, and reduce the heart rate at rest. 4. Improve and improve liver function, increase liver detoxification and detoxification ability. 5. Promote the secretion of enkephalin, relieve tension and anxiety, and reduce stress.

6. Increase the elasticity of blood vessels, increase coronary perfusion, and reduce the occurrence of cardiovascular and cerebrovascular diseases.

The main thing is that it is good-looking, of course, it is too much, and it is too developed to affect the appearance.

What needs to be corrected is that muscular development has little to do with the overall quality of the body and the so-called "combat effectiveness"; there are not only technical reasons for this, but also the factor of joint muscle strength, so the muscles of the officers and men of the People's Liberation Army and the Armed Police Force will not be very large, unless they are otherwise interested in exercising.

When the pectoralis major muscle is contracted, the humerus can be adducted and supinated, and the ribs of the chest can stretch the raised upper limb backward to help breathing; Contraction of the clavicle causes the shoulder to flex.

One of the structural characteristics of the pectoralis major muscle is that the fibers at different starting points have different ends. The fibers of the clavicle form the anterior layer of the flat tendon outward, the fibers located on the lateral side terminate at the upper end of the lateral lip, and the fibers on the medial part terminate at the lower end of the lateral lip.

The fibers of the thoracic ribs and abdomen are upwards and outwards, behind the inferior fibers of the clavicle. This structure allows the upper and lower fascicles to stretch the same as when the upper arm is abducted.

The main thing is horizontal flexion of the shoulder joint, as well as shoulder adduction, shoulder flexion, and internal rotation of the shoulder joint.

Near fixation, contraction, can cause adduction, pronation, and flexion of the shoulder joint. Hold it far away, pull the torso closer to the arm.

Shoulder flexion, shoulder extension, 0-90 degrees, shoulder adduction, horizontal adduction, internal rotation.

Exercising your pectoral muscles varies from person to person. People with thin cortex and dry ** show shape relatively quickly, and generally if you practice a part, it will be congested after each exercise, and it looks very good.

Big, but it will recover soon, and the real increase in dimension will usually appear in a month or two, at which time you will find that as soon as you exert force, the muscles will become significantly stiffer, and the edges and corners will also come out.

Some. It is recommended that you do not blindly pursue speed, because if the muscles grow too fast, on the surface your strength increases, but in fact your bone strength and ligaments, joints are strong.

The degree has not yet increased, and at this time, blindly adding weight is the most likely to be injured.

Finally, I wish you a speedy and successful fitness. I feel that it has been helpful to you, and I hope you can choose [satisfactory answer].
