The low paraspinal muscle loading would suggest to prevent fatigue. Apparently, however, the insufficient active stabilisation leads to the remarkable loading of spinal column especially of intervertebral discs and also the muscle spindle activation remains question. When sitting the lumbar spine is continuously in neutral zone when the stabilising function of
muscles is more important than that of ligaments and tendons [36–38]. The continuous loading of passive elements leads to increased stress and fatigue, expose to injury and eventually even pain.
