Long spells in front of the TV inactivate spinal muscles.

Muscles which normally support and protect the lower back could become inactive as a result of slumping in front of the TV or computer screen. Australian researchers studied 19 male volunteers who spent eight weeks in bed. Using magnetic resonance imaging they found that after eight weeks in bed the lumbar multifidus muscles in all the 19 subjects had become inactive. Lumbar multifidus muscles normally keep the spinal vertebrae in place. Back pain can result when they are inactive.
