In recent years, with the fitness craze and the rise of WeChat and QQ, more and more people are keen to "brush" their cards. Whether it is a white-collar office worker who has just finished a day's work or an aunt who has just finished a square dance, even many children will relish their "ranking" on the pedometer every day. "Today, have you broken ten thousand steps?" This slogan was once reprinted by major online platforms, causing widespread concern.

But at the same time, there are also some questioning voices on the Internet: "Can 10,000 steps a day really exercise? Won't it be overloaded? " "Running and brushing your teeth for a long time will hurt your knees and make you more prone to arthritis!" These common arguments are becoming more and more popular and are often forwarded to various family groups by family elders. They "inculcate" and say, "Son, you can run less. Otherwise, when you are old, you can't walk! " At first glance, it's really scary.

So, is running really the culprit of arthritis? Is it really easier to get arthritis if you exercise a lot?

Arthritis caused by "running"? Pathogenic factors have something to say.

First, let's learn what arthritis is. Arthritis generally refers to inflammatory diseases that occur in human joints and their surrounding tissues and are caused by inflammation, infection, degeneration, trauma or other factors, and can be divided into dozens. The clinical manifestations are joint redness, swelling, heat, pain, dysfunction and joint deformity, which will lead to joint disability in severe cases and affect the quality of life of patients [[ 1]]. The number of arthritis patients in China exceeds 1 100 million, and the number is still increasing.

So, what are the pathogenic factors of arthritis? Clinical studies have found that the occurrence of arthritis is mainly related to autoimmune reaction, infection, metabolic disorder, trauma, degenerative diseases (referring to pathological changes such as degeneration and necrosis of tissues and cells) and other factors. According to the etiology, arthritis can be divided into osteoarthritis, rheumatoid arthritis, ankylosing arthritis, reactive arthritis, gouty arthritis, rheumatic arthritis, suppurative arthritis and so on. Among them, osteoarthritis is mainly related to human aging; Rheumatoid arthritis has a complicated relationship with heredity, infection, environment and immunity. Ankylosing arthritis mainly occurs in the spine, which is related to genetic factors and environmental factors, and mostly occurs in male population; Reactive arthritis is an inflammatory joint disease caused by extraarticular infection factors such as intestinal system and urinary system. Gouty arthritis is arthritis caused by urate crystal deposition.

None of the above arthritis types is directly related to exercise. If it has nothing to do with sports strain, only the first kind of "osteoarthritis" is meaningful. However, the survey results show that osteoarthritis mostly occurs in patients with hyperosteogeny. The prevalence rate of osteoarthritis in people under 45 years old is only 2%, while it is as high as 68% in people over 65 years old, which shows that osteoarthritis has a greater relationship with human aging. So moderate exercise will not directly lead to arthritis.

To be healthy, moderate exercise is essential.

Moderate exercise means that athletes choose suitable sports according to their physical condition, venue, equipment and climatic conditions, so that the exercise load does not exceed the human body's endurance, and they feel comfortable without fatigue after exercise, and will not cause excessive fatigue or asthma [2]].

Moderate exercise can greatly promote human health. Moderate exercise can prevent various chronic diseases, such as coronary artery, respiratory system and metabolic diseases. It can also reduce the incidence of cancer; It can also help maintain normal weight and prevent overweight and obesity. Most importantly, moderate exercise can effectively prevent injuries, reduce the probability of sports injuries and maintain good joint function [[3]]. Therefore, moderate exercise has a positive effect on the prevention and protection of joint injuries, and healthy people do not have to worry about the adverse effects of moderate exercise on joints.

The key to reasonable exercise is "moderate amount"

Of course, people with special circumstances, such as those who are suffering from arthritis or those who are physically unfit for running, should also follow the doctor's advice and don't "try to be brave" to challenge some sports that are not suitable for them. This is not only for your own health, but also to reduce hidden dangers and risks.

In addition, the more exercise, the better. All advantages and disadvantages are judged on the basis of "quantification", and the relationship between exercise and health is nothing more than this law. Excessive exercise impairs immune function and affects health. This is because people will produce more hormones such as adrenaline and cortisol during strenuous exercise. When these hormones are increased to a certain amount, the ability of immune organ spleen to produce white blood cells will be greatly reduced, and the activities of A cells, B cells and natural killer cells (NK cells) in lymphocytes will be greatly reduced, among which natural killer cells can be reduced by 35%. The above lymphocytes mainly participate in various immune activities of the body, and if their activity is reduced, it will have a series of adverse consequences to the body. In addition, excessive exercise can also lead to rhabdomyolysis, leading to systemic aches and even renal failure [4]].

Therefore, daily exercise should be timely and moderate, not overloaded, and there should be no "lazy thinking" of "being able to lie, sit and stand". It is a healthy lifestyle to insist on long-term timely and appropriate exercise.
