It may sound like a strange question but “do you breathe properly?” Breathing pattern disorders (BPD) are surprisingly common in the general population. They remain commonly under-recognized by health care professionals and can contribute to pain, fatigue, and dysfunctions in the lumbopelvic region i.e. your CORE!
Core activation remains a hot topic in physical therapy. The problem is that there is not a universally accepted strategy to achieve optimal stability. A decade ago, we started using the “abdominal hallowing” technique which I have talked about before. The abdominal hallowing was an attempt to isolate a key core muscle called the transversus abdominis in which you would “pull your navel in and hallow out your abdoman”. The original work done by Hodges and colleagues on the transversus abdominis also demonstrated simultaneous activation of the diaphragm muscle. The diaphragm, however, took a back seat and has often been ignored during core training. So how do we correct your BPD and “wake up” your diaphragm?
Your diaphragm is attached to your lower ribcage, thoracic wall, and lumbar vertebrae. When you breathe, the diaphragm contracts and pushes DOWN into the abdominal cavity. This movement causes a pressure change which draws air into the lungs. As a result of the contraction, intra-abdominal pressure increases and lumbar spine stiffness, hence stability, also increases. The diaphragm acts in coordination with the abdominal muscles, spinal muscles, and pelvic floor to create lumbar stability in all directions. This is what some refer to as “360 degree of stiffness.” The contraction of the diaphragm creates core stability from the inside-out. When you perform an abdominal hallowing or abdominal bracing you create stability from the outside-in. Professor Kolar and colleages performed two MRI studies of the diaphragm and showed that the diaphragm can perform dual functions of inspiration and stabilization simultaneously! The activation of the diaphragm was shown to vary greatly among individuals. This variability may be the reason why one person can resolve low back pain and another cannot.
Lets take a look at HOW you can activate your diaphragm while breathing and HOW you can enhance the benefit of your core stability exercises. Check out the video below.
