Abstract

Lumbar lordosis (LL) is considered as an important factor of low back pain. Although LL during running (dynamic LL) and anterior pelvic tilt (APT) are thought to increase simultaneously, this relationship has not been examined when running speed is changed. Here we show that dynamic LL increases with the increase in running speed, whereas APT is invariant during treadmill running at 4.0, 5.5, 7.0 and 8.5 m/s in 18 male collegiate athletes. The speed-dependent increase in dynamic LL suggests that runners and coaches should be cautious that greater mechanical load on the lumbar spine might occur during faster running. The inconsistent sensitivity of the lumbar spine and the pelvis to the increase in running speed suggests that practitioners and clinicians should assess LL separately from APT, especially during faster running.
