How does lordosis affect the lower back?

Excessive curve of the low back can create low back pain, increase wear and tear on the intervertebral discs of the low back and cause weakness and tightness of the abdomen, hip flexors, and hip extensors. Excessive low back curve is one of the biggest contributors to low back injuries in the US. Because of the excessive curvature the discs are placed in a strained position and the core, hip extensor muscles become weak, and the hip flexors and back extensor muscles become excessively tight. As a result the body cannot properly stabilize the spine.   To eliminate excessive lordotic curvature, the NASM recommends strengthening the core muscles, the hip extensor muscles, and stretching the hip flexor muscles.

One of the most common causes of low-back pain results from lordosis, or swayback -- extreme inward curvature of the lower back. Excessive lordosis can affect the lower back in several ways: It can increase the risk of muscle fatigue and spasms. It can put added pressure on the disks, increasing the risk of microtears (imagine pressing your hand straight down on a jelly-filled donut; it can absorb that pressure evenly throughout, but if you press harder on one edge, the jelly is more likely to squirt out the other side). And excessive lordosis can cause inflammation of the facet joints of the vertebrae.
