TRANSVERSE ABDOMINUS

So, now that you know where it is…what does TVA do for you?? Well, tons of stuff, actually. This muscle functions as an “internal girdle” for keeping our
abdominal organs in place, helps to promote the important process of carrying
and delivering a baby, and is used to remove the “junk” out from our digestive
system through elimination. On a more
fun note, TVA is the main muscle that contracts during a belly laugh! How about keeping our pelvis in a stable
position? Well, we can thank the TVA for that one too. With a stable lower
spine and pelvis, our arms have the proper neurological recruitment patterns
for efficient upper body movements. If
that isn’t enough, there’s more!! By contracting the lower fibers of this guy,
we can twist our pelvis and trunk/spine to the same side. By contracting the
upper fibers, we can twist our ribcage and spine to the opposite side. This muscle also helps us to bend our trunk
to the side, as well as flex or bend it forward when we touch our toes, or do
an abdominal “crunch.” This is one busy muscle!
How do we isolate this lovely muscle? Some would say: “Pull your navel into your
spine.” That gets it somewhat, but to
really isolate it more specifically, Muscle Activation Techniques (MAT) teaches
2 different ways, one for the lower fibers and one for the upper fibers. Want to try? For the lower fibers, lie on
your back with your left knee bent and foot resting on top of your right thigh.
Feel the left abdominal area between your pelvic bone and bellybutton. Now lift
the left side of your pelvis up and over toward the right side, as if trying to
reach your left knee up and over to the corner of the room where the right wall
meets the ceiling. Feel it? Now try that on the other side and compare what you
feel each way. For the upper fibers, sit on the edge of a chair with your knees
straight and feet flat on the floor. Turn your torso to the right as you feel
the area contracting between your left ribs and the middle of your belly. Got
it? Now reverse it, and again, compare the sensations you notice.
You may be wondering, “What would I notice in my body if the
TVA is NOT working properly??” Well,
that is a very good question. Weakness in the TVA can lead to all sorts of
issues including lower back pain/tightness, neck pain/tightness, radiating
pain/weakness/numbness into the leg(s), inability to reach arms overhead, poor
bladder or sexual control, decreased ability to assist a bowel movement,
difficulty delivering a baby, poor digestion, and more. Ever experience any of
these?
We want to be sure that both sets of fibers on each side of
the body are working throughout their full range of motion before we do
strengthening exercises, just like any other muscle in the body. Once we are certain that TVA is working and
you can feel the precise areas being isolated, you can perform many different strengthening
exercises to target this area. Planks, abdominal curls (“crunches”), torso
twists, windmills, burpees, mountain climbers, pelvic tilts, and knee to chest
marches, to name a few.
As a Muscle Activation Techniques (MAT) Certified
Specialist, I can precisely check your TVA muscles and make sure that they are
performing their jobs efficiently. Who knows, maybe we can have a belly laugh or
two in the process, to help them along! : )
