Estimation of loads and stresses in abdominal muscles during slow lifts

Abstract: Calculations are made of abdominal muscle loads and stresses associated with the development of intra-abdominal pressure during slow, symmetrical lifts. The muscles considered are the rectus, transversus and the external and internal obliques. Muscle loads and stresses have been calculated in an abdominal cross-section at about the level of the third lumbar vertebra. For four cases examined, maximum stress levels for men in the 25-35 years age range appear to be 3p-4p for the rectus muscles, 15p-25p for the tr… Show more

“…9,10,15,22,25 IAP has been shown to unload the spine by generating a trunk extensor moment and tensile loading to the spine. 11 By making the trunk a more solid cylinder by the IAP mechanism, there is a reduction in spinal axial compression and shear loads.…”
