Over time, the joint will lose its protection, and the probability of joint damage will naturally increase.
Instead, you should use it frequently.
He said that arthritis is caused by many factors, excluding arthritis caused by immune system and other unknown reasons (such as rheumatoid arthritis, ankylosing spondylitis arthritis, villonodular synovitis arthritis, etc.), most of which are closely related to exercise.
The study found that only 3.5% of fitness runners had arthritis in their knees or hips, both men and women.
Researchers pointed 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.
In fact, this is a misunderstanding.
However, the American Journal of Orthopaedic&Sports Physical Therapy (JOSPT), the internationally renowned authoritative medical journal, drew an end to this controversial topic in the newly released issue of June 2017.
▲ Image source: The conclusion of Journal of Orthopedics and Sports Physical Therapy that fitness running is good for knee health comes from a meta-analysis of this issue – “Systematic review and meta-analysis: the relationship between fitness running, competitive running and osteoarthritis of the hip and knee”.
Whether regular running is easy to cause arthritis has always been controversial.
“Everyone’s knee joint’s bone strength, muscle strength, weight, lower limb strength line, patella height and other conditions are different, so their tolerance to exercise intensity is also different.
Wu Haobo, deputy chief physician of the Joint and Sports Injury Department of the Second Zhejiang Medical College, said that there were many reasons for knee pain, such as meniscus injury, synovitis, patellar tendinitis, and infrapatellar fat pad inflammation.
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.
They simply do not exercise and reduce the wear of articular cartilage, thinking that this can protect the joint.
Dai Xuesong, director of the Joint and Sports Injury Department of the Second Hospital of Zhejiang Medical University, said that most arthritis and sports injuries were related.
Regular exercise can make joint cartilage often be properly stimulated, promote metabolism, so that joint synovial fluid can flow everywhere in the joints, play the role of lubrication and nutrition.
Excessive and high-intensity running may also cause joint problems.
On the contrary, if you do not exercise for a long time, the synovial fluid in the joint can not fully flow and can not play the role of lubricant, and the muscle tissue around the joint will gradually shrink.
Knee pain after running is often caused by the overload of exercise intensity, resulting in the damage of articular cartilage and meniscus.
Is knee pain related to arthritis after running? Bi Qing said that the knee pain of many people after running is actually due to too little exercise at ordinary times, so when they run occasionally, the pressure before the patella is too large (the patella is the knee bone), causing certain acid swelling and pain.
Bi Qing, director of orthopedics department of Zhejiang Provincial People’s Hospital and deputy director of Zhejiang Provincial Sports Medical Center, also agreed with this research conclusion.
The Journal of Orthopedics and Sports Physical Therapy pointed out that the incidence of arthritis in competitive runners was 13.3%, that in sedentary people was 10.2%, and that in fitness runners was only 3.5%.
This is first of all joint edema.
From 25 studies with a total of 1258100 people, 17 studies with a total of 114829 people were selected for meta-analysis.
When people who do not exercise suddenly move (you need to move something occasionally), the coordination and stability of bones, muscles, ligaments, cartilage and other structures may be insufficient, which often leads to sports injury.
For those who like to sit or do not run for a long time, 10.2% of them have knee or hip arthritis.
If you don’t use it for a long time, the car will break easily.” Dai Xuesong said, the same is true of human joints.
“For example, a car is not meant to be parked in the garage without driving, but to take care of the car.
The risk of knee and hip arthritis will increase for those who sit or do not run for a long time.
Excessive and high-intensity running may cause joint problems, but for ordinary fitness runners, running is beneficial to joint health.
If a person’s knee joint can only tolerate 20 kilometers of continuous running, but must run 30 kilometers, it is easy to cause knee joint damage.” Wu Haobo said, of course, the human body has a certain self-repair ability.
This study was conducted by a research team composed of researchers from the United States, Canada, Spain and Switzerland.
If you do not pay attention to rest and maintenance, it will cause joint damage.
Meta-analysis refers to the systematic, scientific and comprehensive evaluation of many research papers on the same problem by scientists, the removal of those with low quality or unqualified research, and the integration and evaluation of those with high quality research with the help of certain statistical methods, and the final conclusion of scientific recommendations.
Mild pain and injury can be repaired by rest and maintenance.
.
He read the latest research in the Journal of Orthopedics and Sports Physical Therapy and agreed with the conclusion.
For those who participate in competitive running (including athletes who often participate in competitive competitions and professional level), the incidence of knee or hip arthritis is slightly higher than that of ordinary people, but it is not particularly high, 13.3%.
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.
In comparison, the probability of joint injury and arthritis may be lower.
