Does running really hurt your knees?


I have always heard that running can damage the knee.

is this real?

Both runners and non-runners have heard of the high impact strength of running – repeated shocks that occur when you run for miles can cause damage to the knee joint.

But a recent study published in the European Journal of Applied Physiology presented the concept on the front page:

The researchers found that exercise actually reduced the inflammation of the knees of six people, suggesting that the activity is actually more beneficial but not harmful to the joints.

“Whenever you run, you put a load or force on your knees,” says Robert Hyldahl, assistant professor at Brigham Young University. “But the knee is physiologically used for the load.”

The scope of the study was relatively small, in part due to logical challenges. Moreover, the experiment requires the extraction of synovial fluid from the knee cartilage as an indicator of inflammation, which proved to be very difficult, Hyldahl said. Nevertheless, this still illustrates the idea that knee cartilage is used to absorb a type of shock caused by running. So, despite the limited data, it may convince people who think that running is hurting their knees to go out, Hyylhahl explains.

Mark Harrast, director of medicine at the University of Washington’s Sports Medicine Center, agrees, but he said there is a problem: although the latest research shows that running does not cause knee arthritis, as people age, joints will appear routine. Degressive process. Running may cause damage to the knees of people who have suffered cartilage damage in the area.

“If you suffer from cartilage damage due to injury, such as meniscus slippage, rupture or anterior cruciate ligament vacating, and if you run regularly, excessive use of cartilage tissue is a precursor to arthritis,” Harrast said.

If you have had a knee cartilage surgery or have been traumatized, Harrart recommends rehabilitating the treatment and then performing a less impact exercise, such as swimming or cycling, on recovery. But as long as your knees are in good condition, running will not cause significant damage.

“Anyone can get hurt and there is a common pain called “the runner’s knee,” but this is just because of the pain caused by overuse of the area,” Harrast said. “Running is a sport that is easy for people to learn. Everyone can run. But the key is to be gradual, then listen carefully to the signals from your body and pay attention to all kinds of soreness.” No matter what exercise, it is beyond normal. The load range is not good.
