Diaphragmatic breathing might be the most important forms of breathing. This is the way all of us breathed when we were young children. Let's explain the mechanics of breathing.  The diaphragm is the muscle that was designed for inspiration. It is a dome shaped muscle that separates the abdominal cavity from the chest cavity which is where the lungs reside. When the diaphragm contracts, it pulls air in to the lungs from the bottom of the chest cavity. It pushes the abdominal contents out of the way causing the abdomen to expand predominantly in the anterior or forward direction. There is expansion to the sides, but this is not as obvious as the anterior displacement.  This expansion draws air in the lungs causing them to inflate. Expiration actually occurs when the diaphragm relaxes. The tension that has been built up from inhalation results in downward pressure of the ribcage and posterior pressure of the abdomen. This natural tension forces the diaphragm and lungs back to their resting position. 

The diaphragm is a special muscle designed to contract and relax thousands of times a day without getting tired. it is therefore more efficient at this task since that is what it is designed to do. Accessory muscle breathing is a type of breathing which utilizes the muscles the attach to the ribcage. These muscles are designed for movement, not breathing. They cannot contract thousands of times a day without becoming fatigued.  It is more efficient to utilize the diaphragm.  It is only once we learn to utilize the diaphragm correctly that we can learn to breathe efficiently and minimize wasted effort. Efficiency is very important when trying to restore pulmonary function or optimize human performance.
