How Physical Inactivity Affects the Spine.
MRI scans conducted on 72 older adults found that physical inactivity can be detrimental to the spine. Researchers observed the intervertebral disks of those with low physical activity levels appeared to be shorter than the disks of those who were more physically active. Previous research suggests a reduction in disk height is associated with a greater risk for back pain. The researchers also found the lumbar stabilizing muscles of inactive participants were more likely to have fatty deposits, suggesting compromised function.
