As the spine extends (or bends backwards) the facet joints are loaded, and the interspinous ligament is compressed, both at risk for injury. Sit-ups produce large shear and compressive forces on the intervertebral discs and across the lumbar spine.14,15,16Increased muscle activation anteriorly results in both initial hyperextension and subsequent hyperflexion of the lumbar spine, contributing to large compressive forces during sit-ups.17,18, Traditional sit-ups impose 3,300 N of compression on the spine.14 The National Institute of Occupational Safety and Health has set the action limit of low back compression at 3,300 N because repetition loading above this level is linked with higher injury rates, yet this is imposed on the spine with each repetition of a sit-up.1.
