What is extension?

Protation is an anatomical term used to describe the effect of drawing the shoulder blades and slightly apart. This scapular protesting creates a visible forward pressure from the shoulders. While the stretching term can be used to describe movement for pressure forward several other parts of the body, such as the head relative to the neck, most often concerns a specific action in the shoulder belt.

The opposite of pulling, which includes the back of the shoulder blades back and together, the stretch is allowed to allow several muscle groups in the upper body. Of these, the most important serratus is the front. The front serratus is located just below the breast and above the belly on both sides of the rib cage. It comes along the side of the chest from the highest eight or nine ribs, wrap around the side of the body and inserts along the middle or inside the edge of the shoulder blade. He has a ribbed look when his fibers run like the ribs: horizontally and slightly tilted up as they travel from the middle line of the body.

In addition to stretching the shoulder blade, serratus helps front stabilization and rotation, which helps to turn the shoulder blades up when it attracts them first. This muscle is very pronounced in boxers who use it to stretch the shoulder blade when they throw a blow. In this case, stretching is also a useful tool for defense: internal rounding of the shoulders and pulling forward creates a smaller surface area of ​​the fuselage for opponents and therefore a smaller area for protecting the arms.

Another muscle used in the extension of the shoulder blade is pectoralis minor. Much smaller than his neighbor in the chest, the pectoralis major, there is a smaller pectoralis below it. Instead of running horizontally, however, pectoralis minor runs perpendicular to the pectoralis major, with the fibers vertically span the upper chest basket. Fastening the tendon to the top of the blade is the pectoralis minor primarily responsible for pressing the shoulder or pulling down, but also involved in stretching the inner edgeforward.

For many individuals, especially those sitting all day in front of the computer, the muscles are connected in stretching tight and exaggerated. This imbalance can be corrected by strengthening the muscles involved in the pull, those found between the shoulder blades in the upper back, such as rhombuses, as well as by stretching the protractors. If you do, it will help pull the shoulders back where they belong to a neutral postural alignment.
