It was subsequently studied how many new cells in the intervertebral discs were formed in rats that had run on a treadmill for about one hour a day compared with animals that had only moved around freely in a cage. “This is new knowledge showing that the intervertebral discs can be positively affected by physical activity,” says spine surgeon Helena Brisby.
Physical Exercise Has Positive Effects on Intervertebral Disc Cells
Pain in the lumbar spine is common and may be due to disc degeneration, which means that the disc cells no longer have normal functions. Based on the results of the study, the research team led by Helena Brisby and Björn Rydevik intends to go on to study whether the cells in degenerated discs respond as positively to exercise as they have now shown to do in normal discs.
“Physical exercise is already an important part of the treatment for back pain today, but there is limited knowledge about the specific effect that exercise has on the intervertebral discs and what the optimal dose of exercise is,” says Björn Rydevik.
The research team plan for continued studies with this animal model, which hopefully will establish whether exercise can prevent disc degeneration and could consequently prevent back pain, but also aims to study the effect of exercise when back problems have already arisen.
