The rapid development of intelligent terminals and network communication has made games an indispensable "electronic mustard" in life. The babies who hid in the game machine hall 20 years ago have become parents who hurriedly come to the school gate to "eat chicken".
With a broad mass base, e-sports games are inevitably booming. Wang Sicong, the former "national husband", did the "most reliable thing" by becoming the China E-sports Club Alliance in 2012, making China's e-sports industry sports and internationalized, and also led the team to win China's first League of Legends global championship.
The Olympic Esports Series, a global event created by the IOC and International Sports Federations in partnership, also began last year. The first batch of 9 events are still sports competitions, and the best results of Chinese players are: taekwondo, third.
To be "faster, higher, stronger", you have to work hard, and there is pain.
A lot of people are about to laugh out loud and say, "Sitting in front of the computer all day, just moving your hands, what's the pain?!" ”
Yes, everyone's stereotype of "e-sports player" is probably a fat house stuck in front of the computer. In any case, they are not athletes in the traditional sense!
Most people type a lot in front of the computer, and they will have wrist pain and shoulder and neck tension. Competitive level play, which is caused by excessive use of too many movements and repetitive hand and wrist movements, which leads to the formation of tenosynovitis.
The tendon sheath is a very clever design.
Your fingers flutter flexibly, and it is the muscles that move through a "tendon" (tendon) that pulls it around; So this "tendon" is long and short, "rubbing around" in the flesh, will it "stick" to the muscles? Will it be "bruised"?
Well, that's kind of what it means.
The tendon sheath is the "protective cover" of the tendon, fluffy, soft, and filled with "lubricating fluid" - tendon sheath synovial fluid, to ensure that the tendon will not be "squeezed" by the bones and muscles next to it, and will not "rub" against them.
As shown in Fig. The tendon sheath is divided into two layers around the tendon, and the cavity between the two layers is the synovial fluid cavity, which contains the synovial fluid of the tendon sheath. The inner layer is closely attached to the tendon, and the outer layer is lined with the tendon fiber sheath, which is jointly combined with the bone surface and has the effect of fixing, protecting and lubricating the tendon from friction or compression.
However, here comes the problem again. The tendon sheath protects the tendon from head to toe, and the muscles and bones can't stand it, and it has to be in contact with the tendon sheath!
When the joint moves, the tendon and tendon sheath rub against each other, and if the friction is excessive, it can produce damaging inflammation of the tendon and tendon sheath, causing swelling, which is called tenosynovitis.
Now we finally know why "Internet addicted teenagers" e-sports players are more susceptible to tenosynovitis, using the mouse and keyboard for a long time and with high intensity, and frequent friction of wrists and finger joints, it is easy to have conflicts!
Interestingly, back in 1990, the New England Journal of Medicine, one of the leading publications in the medical community, reported a "new" disease: nintendinitis. Presumably those who play games and understand medicine, they probably laughed when they saw this word.
Nintendo, Nintendo, is a big player in the gaming industry. The second half of the tendon is exactly the English "tendon", -itis means the suffix of inflammation, tendinitis tendonitis. Strung together: Nintendo-induced tendonitis – nintendinitis.
It seems that the "game predecessors" many years ago have been suffering from tenosynovitis caused by long-term gaming, which is really a historical problem!
Painful swelling. In tenosynovitis, where there is a tendon sheath, it may become inflamed. Fingers, toes, wrists, ankles are all possible. But the most common part of the thumb at the base of the thumb, which connects to the wrist, is technically described as the radial styloid process and the first metacarpal bone. Presents as localized pain, sometimes radiating to the surrounding area.
Slight or noticeable swelling may occur around the affected tendon sheath.
Bounce. When the finger is bent, it will make a trigger-like action and pop, and in severe cases, the finger cannot be bent or straightened, and the movement is severely restricted.
1. Proper warm-up: Before engaging in any game, doing a proper warm-up can help reduce the risk of injury. The easiest way is to move your wrist, just like a warm-up exercise before every physical education class, twist your wrist and do four or five sets to fully activate your wrist muscles and keep them in a comfortable state.
2. Pay attention to posture: Maintaining correct posture and technique, especially when performing repetitive activities, can reduce the pressure on the tendon sheath. Ergonomic keyboards, mice, wrist pads, etc., can help us have a comfortable and correct posture to enjoy the game.
3. Moderate exercise: This may be difficult for professional esports players, but it is suitable for the vast majority of people, avoid overusing hand muscles and reasonably control the intensity and frequency of exercise.
1. Rest: If it is only mild inflammation and pain, just give the injured area enough rest time to avoid further damage.
2. Hot and cold compresses: Alternating cold and hot compresses can relieve pain and reduce swelling.
3. Physics: Physics, such as sports, massage, and other techniques to speed up the process, is what most professional esports players need.
4. Surgery**: If there is acute purulent tenosynovitis, the tendon sheath has been infected and suppurated, and surgical incision, drainage and decompression are required.
Although games are a pleasant way of entertainment in life, you should also pay attention to control, protect your tendon sheath, and avoid the formation of chronic tenosynovitis, so as to have a healthy and interesting game career!
