Yes, it's true: Jogging, long thought to hurt knees with all that pounding and rattling around, may actually be beneficial for the complex and critical joint. There are caveats, though, especially for people who have suffered significant knee injury or are overweight. But for the most part, researchers say, jogging for your health seems like a good idea.
David Felson, a researcher and epidemiologist at Boston University School of Medicine, says past concern about jogging and knees centered on the continuous impact of the foot to the ground and suggestion that it caused degeneration of the knee and the onset of osteoarthritis. But when researchers actually studied the impact of running on knees, he says, that's not what they found.
"We know from many long-term studies that running doesn't appear to cause much damage to the knees," he says. "When we look at people with knee arthritis, we don't find much of a previous history of running, and when we look at runners and follow them over time, we don't find that their risk of developing osteoarthritis is any more than expected." Both types of studies agree, says Felson, that recreational running doesn't increase the risk of arthritis.
