Avoiding exercise because of lower back pain? Scientists nowsay that lack of activity, such as sitting in front of yourcomputer or TV, deactivates the muscles that support yourspine, causing the pain in the first place.
Emma Young reports in New Scientist that when young menspent eight weeks in bed in a German study, most of themdeveloped lower back pain. This shows that the absence ofweight on spinal support muscles can sometimes be just ashard on your back as a physical injury.
Normally our spinal muscles work continuously to support andprotect our lower backs. Heavy lifting, whiplash or otherinjuries can damage these muscles, but only 10 to 15% oflower back cases begin that way. Usually the cause of thepain is mysterious.
