This is a phrase that one hears a lot when people are talking about Pilates. But, what does it mean? The easiest way of explaining it to the lay person is that;
“Core stabilisation refers to the abdominal muscles, namely the transversus abdominus, which wraps around the torso like a corset. When this is engaged together with the muscles of the pelvis then the overall stabilisation of the ‘core’ or torso is more attainable”.
However ‘core stabilisation’ actually means and in volves a lot more than that. When we refer to the ‘core’ we are actually referring to the pelvis, abdominals and vertebral column. The main muscles responsible for our core stabilisation are deep muscles which include: the transversus abdominus (TA as mentioned above) the internal and external obliques ( the two layers of abdominal muscles lying on top of the TA) the multifidus (which lies alongside the spine from the pelvis right up to the neck) and the pelvic floor muscles (the urogenital triangle that sits right at the base of the pelvis). It is the ability to engage and recruit these muscles and stabilise the body whilst moving that defines ‘core stabilisation’. But it is important to engage the above muscles prior to moving in order to achieve the desired outcome. The focus is on stability, breathing, and smooth, coordinated movement.
The diaphragm also plays an important role, creating not only the action of breathing but subsequently vital intra abdominal pressure. It is the action of the diaphragm along with the main stabilizing muscles contracting together upon the incompressible contents of the abdominal cavity (ie the internal organs or viscera) which provides support to the spine and pelvis during movement.
As you can see there are a lot more muscles involved in the overall achievement of stabilisation than often thought. This need not be a daunting prospect though. Rather when you perform your Pilates exercises try to visualize your body working as a whole, with every limb and major muscle group having a role to play, even if it needs to be still! Become conscious of the whole shape of an exercise and focus on how you move through an exercise rather than getting through an exercise.
