The transversus abdominis muscle, so called from the direction of its fibers, is the most internal of the flat muscles of the abdomen, being placed immediately beneath the Obliques interns.
Origin:
- It’s originated from the last 5 or 6 ribs
- Lumbocostal ligament
- L1 – L5 costiform processes
- Iliac crest and in the Arch of Farlopio.
Insertion:
- It inserted into the midline, making an aponeurotic curve which is maximum at the level of the navel, covering the posterior face of the Rectus abdominis, leaving its first lower third free (Douglas Arch).
Action:
- Constrictor of the abdomen.
- Helps increase intra-abdominal pressure, contributing to defecation, urination, vomiting, childbirth, coughing, forced expiration.
What is and how to work the transversus muscle?
The transversus muscle is the great forgotten when working on the abdominal block.
A concentration and knowledge of our body is necessary for its correct activation.
It is difficult to activate it while executing other movements (hence the importance of concentration)
It has no dynamic function, so we have to learn to control and activate it voluntarily.
In order to understand the activation of this muscle, it is important to know where it is and its functions.
Because no matter how much we hear “navel inside and up” or “take the navel towards the spine”.
If we do not understand the reason for this, it will be very difficult to learn how to activate it correctly.
The transversus abdominis muscle is located in the anterior, lateral and posterior part of the abdomen, below the minor oblique.
It is the innermost face of the abdomen and extends from the spine to the mid line.
How do you activate this abdominis muscle?
- Supine on your back.
- Knees bent feet flat on the floor.
- Hip width apart.
- Place your index and middle finger inside the iliac crest.
- Move your fingers to cm toward the mid-line and down toward your foot.
- To activate your transversus abdominis muscle, draw your belly button into your spine or toward the floor.
- You should feel a slow tension under your fingers.
- When you can feel the contraction try to keep it for 12 seconds, breathing normally.
- Once you can do 12 repetition of 12 seconds while breathing progress to different movements always keeping the same transverse abdominal contraction.
For example: If your heels one at a time 12 times, slide your heels down one at a time ten times.
Lift your arms up alternatively ten times, or the few knees up I’ll turn it with ten times.
Complete three sets of ten repetitions
Functions of the transversus muscle
Among the functions of this muscle we find that it is an expiratory muscle, it participates in:
- Coughing
- Urination
- Defecation
- Contracts and tightens the abdominal wall
- Compresses the viscera.
If we think about all its functions , we should come to the conclusion of how important it is for our health.
Since its activation and toning supposes preventing and protecting the lumbar spine so prone and susceptible to pain in our day to day life.
We should bear in mind that keeping it in a suitable tone means maintaining a suitable posture so that we protect the lumbar spine, and maintaining correct intestinal function.
One of the best ways to learn to activate, control and strengthen the transverse in a controlled and safe way is with the Pilates method.
