Why are inner core muscles important?

Why do even fit people with a “six pack” of abdominal muscles develop low back pain associated with decreased inner core control?

Your core has multiple layers of muscles – the outermost muscles being the rectus abdominis (or the “six pack” muscle), external and internal obliques.

Your inner core stabilizing muscles are the transverse abdominis, multifidus, pelvic floor muscles, and your diaphragm. Transverse abdominis wraps around like a stabilizing corset, with muscle fibers going in a horizontal direction attaching to the thoracolumbar fascia, iliac crest (in your pelvis), lower ribs and inguinal ligament. See the illustrations below to visualize the muscle location.



Transverse Abdominis

These local stabilizing muscles’ main function is to maintain your posture against gravity throughout the day and they are designed to sustain a continuous activation and always be “on.” Other types of muscles like the rectus abdominis (“six pack”) and obliques are designed to be able to produce a muscle contraction with a notable change in muscle length in order to help you sit up or rotate your body when you needed. However, these muscles are designed to be “on” only when you are truly moving your body. For this reason, they are often called global movers. On the other hand, stabilizing muscles rarely get a break from gravity because we stand and sit the majority of the day and are responsible for initial control of every movement.

Think of the inner core stabilizers as a foundation for your house. If you build a shoddy foundation, the house will eventually break down due by instabilities. This sometimes happens with clients complaining of low back pain. Their stabilizers do not activate when they need to and they rely on more superficial muscles to brace themselves against gravity, which over time, creates an unnecessary amount of tension and pain in the body.

A common complaint from my clients with low back pain due to a decrease in inner core control, is pain during transitional movements, such as standing up after sitting, rolling over in bed, or holding prolonged static postures – standing, driving, or working by the computer. Some people have pain, or dysfunction, with higher level activities such as when trying to hold a plank or hit a tennis serve without hurting their back. In these scenarios, it’s possible the inner core does not know how to “kick in” at the right time and the back starts working over-time and compensating for a sleepy inner core.
