Lower lumbar spine axial rotation is reduced in end-range sagittal postures when compared to a neutral spine posture.

Sports such as rowing, gymnastics, cycling and fast bowling in cricket that combine rotation with spine flexion and extension are known to carry greater risk of low back pain (LBP). Few studies have investigated the capacity of the lumbar spine to rotate in various sagittal positions, and further, these studies have generated disparate conclusions. The purpose of this study was to determine whether the range of lower lumbar axial rotation (L3-S2) is decreased in end-range flexion and extension postures when compared to the neutral spine posture.
