More and more frequently I am finding that a cue of “keep
your core tight” elicits a response of simply holding your breath, not engaging
the proper muscles. Clients of all skill levels typically have a hard time
differentiating between proper muscle engagement and the faux core of holding
your breath.
This poses a major problem for two reasons: False sense of
stability and the positioning of your diaphragm. The false sense of stability
is a problem because the purpose of engaging your core is either for stability
or to train the muscles to be able to provide that stability, or both. If the
muscles aren’t actually providing stability, then the main reason for doing the
exercise isn’t achieved and therefore you aren’t getting what you need from the
exercise. In short, the partial pressures within the cavities in the body will
provide a stable wall to push against for the surrounding musculature. An
example of this is trying to push something from the middle of the room versus
if you have the wall at your back. When that stability is provided, the
exercise becomes less strenuous and I don’t have to work as hard. Similar techniques have a place, but they are not functional. This not only
doesn’t achieve what we want from the exercise, but can put the body in unsafe
positions and train us to move improperly.
Who is this diaphragm and what does he do? The diaphragm is
the muscle that is responsible for breathing, and has a lot of strong
attachments to surrounding structures, such as the lumbar spine. Rib
positioning is extremely important. Holding our breath with typically cause the
ribs to flare up and out, causing a compensatory arch in the lower back due to
the attachments with the diaphragm and encouraging a position in which the core
doesn’t have to work. This again, teaches us to move improperly and negates the
purpose of the exercise. The over-activity of the incorrect muscles is what
causes people to get hurt. The diaphragm is being engaged correctly, but
separation of diaphragm and core engagement is essential to performance and
training.
Oh, and by the way breathing provides us with oxygen which
we kind of need for exercise, and living in general. Listen to your coaches
cues about breathing, and do your best when you are on your own to take control
of your ribs and breathing and encourage proper core control. It Matters!
