Core stability is fundamental for maintaining good posture and protecting the spine. It is the foundation for all other exercise and movement. The term “core” refers to your trunk - between ribcage and pelvis.  This is like a cylinder – the walls of the cylinder are your abdominal muscles (and spine/spinal muscles at the back), the floor of the cylinder comprises your pelvic floor muscles and the roof is your diaphragm (main muscle of breathing).  If these muscles are working optimally you should be able to move and breathe freely while staying stable. 

Why is it important to be “stable”?   

There are muscles throughout the body whose function it is to provide stability (including the rotator cuff muscles of the shoulder and the deep hip muscles).  This stability allows big strength muscles to do their job of carry, throw, jump without injuring the joint.  Similarly, the deep core muscles stabilize the trunk like a brace so that the back is not injured with lifting, bending and sitting. The core also provides a strong platform for delivering strength from the limbs.  You might imagine a footballer with a wobbly core is unlikely to run fast, and is more likely to sustain injury.   For this reason, core exercises are often included in the rehabilitation of upper and lower limb injuries, not just back complaints.

Our core not only helps us be active, but also helps us be still.  If you are someone who “props” on walls and furniture, who can’t sit unsupported, or hangs on one hip while standing, you may have a weak core.  Improving your core muscle activity may help avoid pains due to these asymmetrical postures and allow you to be comfortable in static postures.

At Macquarie Street Physiotherapy we can help you by giving advice and/or exercises to do at the gym or home. Alternatively, you can come to our Core Stability Classes to get some regular practise.
