London - Moderate exercise may be the best way to beat the most common side effect from taking statins.
Physical activity is thought to stop the muscle pain which can come with taking the cholesterol-busting drugs.
Evidence that around seven in 10 professional athletes cannot tolerate statins due to muscle pain has added to the belief that exercise makes the side effect worse.
But scientists funded by the British Heart Foundation have now found moderate exercise could actually help, after identifying the cause of sore and weak muscles. Their study, using rats and muscle biopsies from patients taking statins long-term, found the drugs cause calcium leaks from muscle cells.
