Intra Abdominal Pressure

Intra Abdominal Pressure & Thorocolumbar Fascia

Want to protect your lower back when lifting heavy objects? Well, then make sure there is adequate Intra Abdominal Pressure (IAP) in the abdominal cavity.

Intra-abdominal pressure is defined as the steady-state pressure concealed within the abdominal cavity and resulting from the interaction between the abdominal wall and viscera. IAP oscillates according to respiratory phase and abdominal wall resistance.

Fascia researcher Mark Driscoll discovered in his experiments that when squatting to lift heavy things, the IAP is higher, resulting in a better distribution of load evenly on the Thoracolumbar Fascia (TLF), hence allowing safer movement of the spine.

When bending over in a kyohotic configuration, the IAP drops, putting more strain on the TLF, which will affect the biomechanics of the spine.
