Is Running Bad for Your Knees?

November 14, 2012 2:51 pm 9 comments

Do you avoid running because it’s bad for your knees and joints? Some people believe if they run to stay fit they’ll end up with joint problems and osteoarthritis. Is there any truth to this idea?

Running and Joints: Does Running Increase the Risk of Joint Problems?

There’s very little evidence that running increases the risk of joint problems or osteoarthritis later in life. In a study published in JAMA in 1986, researchers found no increased risk of clinical osteoarthritis among a group of middle-aged runners compared to a control group. More good news. These runners enjoyed higher bone-densities than their sedentary counterparts – one of the many health benefits of running.

Most recent studies suggest that running not only doesn’t increase the risk of joint problems, it actually prevents them. It strengthens the ligaments that support the joints, and it keeps the cartilage healthy by supplying it with greater oxygen and nutrients. Some studies show that runners have thicker, healthier cartilage in their knees. They also have a lower risk of disability than do couch potatoes, which is not surprising considering the many health benefits of running.

Running Does Have Risks

Running may not be harmful to joints, but improper technique and running too much too soon can lead to painful stress fractures. These tiny cracks in the bone, usually the shinbone, happen when runners try to log too many miles too quickly. Runners with well-developed calves have stronger shinbones and are less likely to experience a stress fracture from running – so it pays to strengthen the calf muscles.

How to Be Kinder to Your Joints

Get a quality pair of running shoes with good foot and ankle support, and vary the surfaces you run on. Do calf-strengthening exercises such as calf-raises to strengthen the muscle that surrounds the shinbone to reduce the risk of stress fractures – and make sure you’re using good running form to get the health benefits of running – and avoid injury.

Running and Joints: The Bottom Line?

Running won’t increase your risk of osteoarthritis, but it can increase your risk of stress fractures and overuse injuries. To prevent this, wear proper shoes, and use good form. Enjoy the many health benefits of running, but don’t overdo it. Increase your distance gradually, and don’t run more often than every other day.

    Salomon’s “Door to Trail” running shoe: The XR Mission CS

    I admit it, I am already a fan (and regular user) of Salomon shoes.

Now, Salomon have come out with a completely different line of running shoes, their “Door to Trail” series. These shoes are basically hybrid trail/road runners, incorporating the cushioning of a road shoe with the protection and grip of [...]
