Reducing Lumbar Spine Injury Risk

When a person sleeps at night, osmotic pressure causes the discs to expand. This decreases lumbar flexion by about 5 degrees. With this, after rising from bed, the lumbar spine is more resistant to bending, with the muscles surrounding the spine unable to compensate for the motion reduction. It has been estimated that intervertebral stresses are increased by 300% and ligament stresses by 80% in the morning compared to the evening, therefore increasing risk of injury, especially during bending and weighted movements. Waiting at least an hour before engaging in exercise would be smart. This allows for hydrostatic pressures to reduce tension in the tissues.
