No Risk of Osteoarthritis from Physical Activity

International study allays osteoarthritis concerns.

Knee osteoarthritis

For years, people have raised concerns about the risks of physical activity on joints; however, study after study shows that the benefits of exercise outweigh the risks for most people—even for frail, elderly individuals. New research adds to our understanding of the limited risks of physical activity and its connection to osteoarthritis.

Researchers from England’s University of Southampton and University of Oxford conducted a study to evaluate risks of developing knee osteoarthritis from physical activity. They examined data from six global community-based studies that included more than 5,000 participants who they followed for 5–12 years.

Data analysis showed that neither the amount of energy expenditure of physical activity nor weekly hours spent training were associated with increased risk of developing knee OA. This is good news for clients who may be concerned that being active may increase knee arthritis risks.

The research is reported in Arthritis & Rheumatology (2021; doi:10.1002/art.42001).
