Running Might Not Wreck Your Joints, Research Shows

Hit the Pavement: For years, runners have been warned that pounding the pavement could wear down their knees, ankles, and hips. New research suggests that assumption may be too simplistic, and that even people with osteoarthritis can safely run.

The Study: Researchers at the University of Essex examined data from 17,661 people with knee or hip osteoarthritis. They found that those who took part in higher-impact activities, including running and tennis, had 36% to 48% lower odds of undergoing a total hip replacement within the next year. Higher-impact exercise was also not associated with a greater likelihood of undergoing a total knee replacement during the following year.

The Takeaway: The findings challenge the idea that high-impact exercise is inherently bad for your joints. The study authors said that high-impact exercise “should not be routinely discouraged based on joint replacement risk alone.” If running is something you enjoy and your joints tolerate it, an osteoarthritis diagnosis doesn’t necessarily mean you have to quit. 

Keep in Mind: This was an observational study, so it can’t prove running prevents joint damage or replacement. People who are able to run may already have healthier joints, especially if they also do regular strength training.
