Well, now you can tell all the naysayers that running (at any age) does not increase your risk of osteoarthritis (or wearing out of your joints), in fact they may even prevent the condition. This information was presented at the annual meeting of the American College of Rheumatology.
Researchers did a long term study on 2,683 subjects at four stages of their life : 12-18, 19-34, 35-49 and 50 and older. They were classified as a runner at that stage if they listed running as one of their three main activities.
X-rays of the knees were collected as well as subjects' reports of symptomatic pain. The knee x-rays were repeated again two years later. Analyses showed that 22.8 % of the participants who were runners had need osteoarthritis compared to 29.8 % who had never been a runner. And get this, average age of the participants was 64.7 years.
The authors concluded that "non-elite running at any time in life does not appear detrimental and may be protective" in regards to developing knee osteoarthritis.
