Excessive lumbar lordosis has received much attention as a key factor in lumbar spine injuries such as spondylolysis. In static conditions such as standing, lumbar lordosis is closely linked to anterior pelvic tilt. However, it remained unclear how these postural parameters respond to increasing speed during running.
This study investigated how lumbar and pelvic posture respond to running speeds from low to high. We found that lumbar lordosis increased progressively with higher running speeds, whereas anterior pelvic tilt remained unchanged. These findings suggest that the lumbar posture may be exposed to greater mechanical load during high-speed running. Additionally, since lumbar lordosis and pelvic tilt responded differently to running speed, this study highlights the importance of direct measurement of lumbar curvature rather than relying on alternative parameters when evaluating posture during running.
