Heavy lifting, twisting and bending can do damage to the discs in the back by reducing the flow of nutrients to the disc cells, a study says.
Disturbing the balance of nutrients in the discs can then lead to the onset of degenerative disease.
Writing in PLoS Computational Biology, Spanish experts say a normal level of physical activity helps cell nutrition.
Lower back pain, which is linked to degenerative spinal discs, could be caused by this lack of nutrients.
Previous research has shown that 80% of the active population suffers from low back pain at some point in their lives.
But little was known about the chain of events which changes normal, healthy ageing discs into degenerative discs.
diane has degenerative discs but has always eaten healthy food
are they saying its not eating healthly or heavy lifting
