Myths and realities of running – Does running cause osteoarthritis?
Running is a sport that is visibly growing in popularity. The simplicity of this sport and its health benefits fuel the motivation to lace up your shoes and go for a run.
As with many things, unfortunately, a huge number of myths related to running circulate through word of mouth and personal anecdotes. In this series of blog articles, we set the record straight by demystifying certain key aspects of running.
Does running cause osteoarthritis in the knee?
NO, but…
Amateur or recreational runners (that is, everyone except professionals) develop less osteoarthritis in the knee and hip than non-runners. How is this possible? Well, the body adapts to the mechanical stress caused by running by becoming stronger and more robust. Cartilage therefore stays healthy longer!
BUT, elite runners (professionals or those who have participated in international competitions) have more osteoarthritis in the knee and hip. This could also be explained by the repeated injuries sustained by these professionals.
In addition, sedentary people have more osteoarthritis in the knee and hip than runners.
What can we conclude from all this? Whether you do nothing or run professionally, you're more likely to develop osteoarthritis. If you run as an amateur, you're less likely to develop it.
