Psoas Muscle in Tai Chi
The psoas (pronounced so-az) muscle isn’t well known and yet plays a huge role on our bodies. It is the deepest muscle in the body and unlike most other muscles it lays buried. This muscle is vital for appropriate alignment/structure, full muscular range of motion and correct joint rotation.
- A muscle that is 16 inches long
- The only muscle that connects the lower spine to the legs
- Connection from: twelfth thoracic to the fifth lumbar
- Connection to: lesser trochanter of the femur
- Made up of psoas minor and psoas major
- Both hip flexors are together known as the iliopsoas
- The psoas connects to the diaphragm by connective tissue/fascia which directly relates to our breathing ability and capacity as well as the automatic fight or flight response.
- All of the internal organs connect with the psoas or diaphragm muscle
- Above diaphragm: heart, lungs
- Below diaphragm: stomach, liver, gallbladder, spleen, colon
- Outer edge of psoas: kidneys
- Inner edge of psoas: abdominal aorta (blood flow to the pelvis and legs)
- Parallel of psoas: ureters (tubes that propel urine from the kidneys to the bladder)
- In front of psoas: bladder, reproductive organs
- Unites the upper body to the lower body
- Hip stabiliser, creating appropriate function/movement of the hip-joint
- Helps create a neutral pelvis alignment
- Hydraulic pump that helps nutrients be drawn in and pushed out of the cells (lymph and blood systems)
- The posture muscle supports the lower spine and abdomen muscles
- Hip flexor, bending the chest towards the thigh
- Supports the organs in the pelvic and abdominal cavity
Psoas and Movement
- A relaxed psoas muscle is short
- Movement lengthens the psoas muscle
- No movement means it shortens and does not lengthen, the less movement you do the more the psoas tightens and restricts mobility
Tai Chi / Qi Gong
- All movements in Tai Chi and Qi Gong come from the psoas muscle.
- Responsible for the hip (Kua) squat in Tai Chi and Qi Gong practices.
- The internal arts activate and condition the deep internal psoas muscle.
- In Tai Chi and Qigong we use deliberate intention to soften and release tension in the hip area; psoas, hip flexors.
- In your practice, you may be contracting your core muscles rather than using your frame (skeleton, peripheral muscles, connective tissue) to move from the core.
- By developing increased body awareness through the mindful movements of Tai Chi and Qigong in general and specifically with the psoas muscle, this can help improve both physical and emotional health.
What Creates a Weak / Shortened Psoas
- Sitting, walking, running for long periods.
- Stress, tension, negative emotions help to create chronic contraction of the psoas muscle which is linked with the brains fight or flight survival response.
- A shortened psoas mimics the fetal position by moving the head and pelvis together.
- Sleeping in the fetal position.
Physical Effects of a Weak / Shortened Psoas Muscle
Chronic contraction of the psoas leads to many physical problems within the body through the shortening of the muscle;
- Lower back, thoracic, hip, abdominal pain or discomfort, extending to difficulty with bowel movements.
- Encourages shallow chest breathing as throws the ribs forward.
- Trunk becomes compressed/shortened which restricts the organs in the pelvic and abdominal cavity (restricting digestive and elimination function).
- Hips thrust forward rotating pelvis and leg.
- Hip socket is compressed affecting rotation of the hip-joint, aiding hip degeneration.
- Lumbar spine compresses affecting blood flow, nerves and circulation.
- Restricts pelvic area affecting sexual function and urine/waste function.
- Restricts pelvic organs causing menstruation cramps.
- In general; lower back pain, disc problems, hip pain, knee pain, sciatica
Emotional Effects of a Tight Psoas Muscle
Chronic contraction of the psoas can lead to many emotional problems within the body;
- The psoas muscle connects directly to our fight or flight response.
- Both automatic responses cause movement in the psoas muscle; a) moving the body into the fetal position or b) engaging the leg and back muscles to move quickly.
- A tense psoas muscle sends a signal to the body that danger is imminent, which over-exerts the adrenal glands and weakens the immune response.
- If your psoas is chronically tense, this puts your body into a constant state of stress.
- A relaxed and appropriately working psoas muscle helps to maintain appropriate signals for the fight or flight response.
