The study was conducted by a research team composed of researchers from the United States, Canada, Spain and Switzerland.

People who do not exercise are more likely to be injured,” said Dai Xuesong, director of the Department of joints and sports injury of the second Zhejiang medical hospital.

They simply don’t exercise and reduce the wear of articular cartilage, thinking that this can protect the joint.

“We studied the situation of 110000 people and suggested that the upper limit of running per week should be 92 km.” this conclusion came from a meta-study in this issue, systematic review and meta-analysis: the relationship between fitness running, competitive running and hip and knee osteoarthritis.

People who sit or don’t run for a long time have knee and hip arthritis The risk of arthritis in the hip will increase.

Among those who like to sit or don’t run, 10.2% have arthritis in the knee or hip.

In this way, the joint synovial fluid can flow everywhere in the joints, which can lubricate and provide nutrition.

People who often run and exercise, as long as they don’t overdo it, will help the blood supply of joints, cartilage, ligament and tendon nutrition.

People who do not exercise usually suddenly move (you always need to run occasionally to move something).

Those who take part in competitive running (including athletes who often participate in competitive competitions and professional level athletes), the incidence of knee or hip arthritis is slightly higher than that of ordinary people, but it is not particularly high, 13.3%.

Excessive and intense running may also cause joint problems.

however, The internationally renowned authoritative medical journal, the American Journal of orthopaedic & sports physical therapy (JOSPT), has put an end to this controversial topic It is pointed out that the incidence of arthritis in competitive runners is 13.3%, that in sedentary people is 10.2%, and that in fitness runners is only 3.5%.

If you don’t use it for a long time, the car is easy to break down.” Dai Xuesong said that the joints of the human body are the same.

Excessive and intensive running may cause joint problems, but for ordinary fitness runners, running is good for joint health.

“Does the knee ache after running have anything to do with arthritis?” Bi Qing said that many people have knee pain after running.

Bi Qing, director of orthopedics department of Zhejiang Provincial People’s Hospital and deputy director of Zhejiang sports medical center, also agrees with this research conclusion.

“For example, a car doesn’t mean that you don’t drive it in the garage, that is, you love the car.

Source | pathological lancet there has always been a saying that “running Baili only hurts the knee”.

Director Dai Xuesong explained that many people believe that running fitness is more or less harmful to the knee joint.

Sitting for a long time not only hurts your knees, but also your muscles and bones.

If you don’t pay attention to rest and maintenance, it will cause joint injury.

knee pain after running , it is often because of the overload of exercise intensity, which causes the damage of articular cartilage and meniscus..

Whether regular running can easily lead to arthritis has also been controversial.

Regular exercise can often stimulate the articular cartilage and promote metabolism.

Why does sitting hurt your knee? Sedentary will lead to poor blood circulation of lower limbs, slow metabolism and reduced synovial fluid secretion in joint cavity.

Sedentary may also cause lumbar spondylosis, cervical spondylosis, constipation, hemorrhoids and other diseases.

Wu Haobo, deputy chief physician of the joint and sports injury Department of the second hospital of Zhejiang Medical University, said that there are many causes of knee pain, such as meniscus injury, synovitis, patellar tendinitis, infrapatellar fat pad inflammation, etc.

On the contrary, if you don’t exercise for a long time, the synovial fluid in the joint can’t flow fully, can’t play the role of lubricant, and the muscle tissue around the joint will shrink day by day.

First of all, it is a kind of joint edema.

“Most arthritis is related to sports injury.

In daily life, the risk of lower limb joint injury is increased, and the risk of arthritis in knee and hip will be increased.

The study found that only 3.5% of fitness runners had arthritis in their knees or hips, both men and women.

Arthritis is caused by many factors, he said, Excluding arthritis caused by immune system and other unknown causes (such as rheumatoid arthritis, ankylosing spondylitis arthritis, villonodular synovitis arthritis, etc.), most of them are closely related to exercise.

Researchers point out that long-term fitness running – 10 years, 15 years, or even longer, is a healthy exercise, which is good for the health of knees and hips.

Over time, the joint loses its protection, and the probability of joint injury will naturally increase.

For female compatriots, sedentary is also easy to lead to leg fat accumulation, elephant legs, which seriously affects their body.

By comparison, the probability of joint injury and arthritis may be higher It will be lower.

He read the latest study in the Journal of orthopedics and sports physical therapy and agreed with the conclusion.

Meta analysis means that scientists systematically, scientifically and comprehensively evaluate many research papers on the same problem, remove those low-quality or unqualified studies, and then integrate and evaluate those high-quality studies with the help of certain statistical methods, so as to finally draw scientific conclusions and suggestions.

The coordination and stability of bones, muscles, ligaments, cartilage and other structures may be insufficient, which is often easy to cause sports injury.

In fact, they exercise too little at ordinary times, so they run occasionally, Pre patellar overpressure (the patella is the kneecap), causing certain acid swelling and pain.

From 25 studies with a total of 125810 people, 17 studies with a total of 11482900 people were selected for meta-analysis.

In fact, this is a misunderstanding.

It is recommended that the maximum amount of running per week is 92 kilometers.

You should use it often.
