The game of soccer is a very intense adversarial sport. It is very unusual for a player to get banged up during a game, and a bad hit can create a large swelling, commonly known as edema. If not treated in time, the inflammation will lengthen and the bruised area will remain swollen and unable to play for a long time. Athletes used to use ice packs in order to get well enough to play as soon as possible. This is where you put an ice and water mixture in a bag and press it against the injury. This lowers the joint/muscle temperature and allows the inflammatory response in the affected area to be controlled. This allowed the swollen area to heal three or four days earlier.
Now there is a better way to get the swelling to heal even faster, and that is to go into the extreme freezer as the title suggests. This technique is called "ultra-low temperature cold therapy", is the use of liquid nitrogen (-196 degrees Celsius) as a cold source, the operating temperature can be as low as minus 150 to minus 180 degrees Celsius, the human body surface cold therapy.
Because the temperature is very low, such a method is more effective than ice packs, and the injury is better faster. But such equipment is relatively rare and much more expensive, and only some athletes do it.
And this liquid nitrogen is not really a liquid, it is a body temperature gas, and does not harm the human body, does not form cryogenic frostbite, the effect is really good.
Thank you for reading Xiangchu Fengyun's article, like Xiangchu Fengyun's article, please point attention, Xiangchu Fengyun will continue to write quality articles to return everyone.
This problem, in fact, the old master Jin Yong has told you the reason. In the "Divine Eagle Couple", the cold jade ice bed of the little dragon lady is this principle. Sitting on the cold jade ice bed practice can be courageous and refined, a year against the usual practice ten years, but also to prevent fire into the devil.
Although Jin Yong's novel has exaggerated dramatization, but there is still a certain truth.
After the game, the athlete's body muscles will feel a sense of soreness, and some old injuries will be hidden pain. In order to eliminate these aches and pains and reduce the body's inflammatory response, sitting in an extreme freezer effectively improves these painful sensations and speeds up the muscles' return to their normal state.
The main ingredient in the so-called "extreme freezer" is liquid nitrogen, which provides an ultra-low-temperature environment similar to that of "ice packs". But the ice pack is only a part of the body for cold compresses, while the liquid nitrogen box makes the whole body out of the ice state.
Because of the extremely low temperature, it is easy to frostbite, so in general, the athlete can only stay in the freezer for a maximum of three minutes. And for male athletes, there is a particularly important precautions, that is, you must wear thick underwear to go in, this is to avoid the male athlete's "balls" frostbite, affecting the function.
Don't underestimate the cost of such a device, it is very expensive, some professional sports organizations provide rental services, the use of three minutes will require 380 yuan. Therefore, it is still rare to see this device in China, most athletes still use the traditional ice pack.
In fact, this is a kind of cryotherapy,
players in the field inevitably bump,
easily lead to redness and swelling of the body and edema phenomenon,
and the freezer box on the one hand is the use of
more than 100 degrees below zero degrees of liquid nitrogen emitted by the steam,
for athletes to achieve the role of calming cold pack,
A special process is adopted inside the emergency freezer,
so that when the athlete goes in,
there is a protective layer around him/her and he/she won't get frostbite.
On the other hand, it's designed to allow for better recovery of bodily functions,
helping the player's muscles to quickly return to normal from a state of exhaustion.
Moreover, it is very effective in reducing the swelling of red and swollen parts of the body.
It can make the blood vessels in the injured area swollen and
blood congestion is improved.
Medically, it is mainly to stop the muscles from continuing to congest and swell. During exercise in competition, the amount of oxygen required for metabolic movement of the muscles is greater than the amount of oxygen ingested by the athlete, so in general the muscles are in anaerobic depletion. In the presence of sufficient oxygen, the body mainly carries out the tricarboxylic acid cycle, or aerobic fermentation. However, in relative oxygen deprivation, it is anaerobic fermentation. As a result, a lot of acid is produced in this process, and lactic acid in the muscles is increased in large quantities. As a result the muscles will feel sore. In this way, it is possible to stop the continuation of the movement of the muscles and organize the occurrence of anaerobic fermentation. And after coming out of the freezer, there will also be blood flow when the muscles return to their normal state, which can further bring out the lactic acid retained in the muscles and reduce the feeling of soreness.
Football is a very strong antagonistic sport, the field you come and go, sometimes too much force, it is inevitable that accidents will occur, after the soccer game, some athletes will be into the emergency freezer to restore physical fitness.
This and the human body when injured, the use of ice packs to relieve pain and swelling reason is the same, we usually see a lot of athletes in the stadium collision strain, limb injuries, it is easy to appear inflammation, edema, if not dealt with in a timely manner, will also lead to aggravation of the condition. At this time, the personnel responsible for emergency medical care will run to the field, with freezing spray repeatedly sprayed players injured place, to achieve cooling, relieve the effect of pain.
The emergency freezer is a therapy that utilizes liquid nitrogen as a cold source to treat the human body's surface, and achieves better results due to low temperatures, wide coverage, and relatively long duration. Some people once expressed doubts that with liquid nitrogen at more than 100 degrees below zero, wouldn't people get frostbite inside the box? In fact, the athlete is only in the liquid nitrogen vapor surroundings, and will not and liquid nitrogen really contact. When out of the freezing cabin, an air film will form around it, separating the human body.
As the environment gets colder, anti-inflammatory proteins start to be secreted in the blood, slowing down the flow of blood in the licensed blood vessels, and the blood starts to slowly pool and flow to the core organs. In this case, the athlete is able to recover faster and more efficiently, relieving the body of fatigue. Of course, this way is only a short conditioning, kicking a game down too much consumption, the real physical recovery also need athletes long-term training and standardized work and rest ah.
The human body tissue in the high-intensity exercise, local blood vessels will expand, muscle tissue will be a large number of congestion. Especially in the case of injuries, local inflammation if not effectively inhibited, will be amplified, including soft tissue subcutaneous some of the injuries, ice packs can shrink blood vessels, reduce blood flow, reduce the rate of tissue metabolism, inhibit the inflammatory response, when the temperature is reduced to a certain level, pain nerve conduction will also be slowed down or blocked, can produce an effective effect of pain relief, which is a common injuries we want to This is the reason why we commonly see injuries to be iced. On the other hand, the low temperature will make the collagen fibers stronger and more elastic, thus protecting the injured muscle tissue.
On the other hand, from the brain's neural latitude, the human body in the cold outside the ground conditions, the nerve tissue will send a signal to the brain, which is in an extremely cold place, so that the brain will control the blood secretion of a special protein to protect the body's muscle tissues and eliminate inflammation.
In addition, we know that lactic acid is produced because of an anaerobic reaction, and this kind of low-temperature treatment, can make more blood flow to the core organs, so that the core organs can get more oxygen, this method is, when the body comes out of the extremely low-temperature environment, the core organs of the body have stored a very large amount of oxygen, and then enter into the high-temperature environment, the core organs will be sent out to pump out this oxygen to the body's tissues, thus effectively inhibiting the production of lactic acid and accelerating the decomposition of lactic acid, accelerating the body's recovery.
Soccer is a very confrontational athletic program, the two sides on the field to fight, see the fans excited. But did you know that after a soccer game, many soccer players go into the emergency freezer? Why is that?
In fact, this is mainly to alleviate the inflammation on the players' bodies and speed up the recuperation of muscle soreness and injuries. Because soccer is a very intense competitive sport, bumps and bruises are normal. Serious bumps can cause edema, which may affect the game if not handled properly. In order to recover as quickly as possible, soccer players will enter the emergency freezer to heal their injuries.
The rapid freezer is a means of using liquid nitrogen at -196 degrees Celsius as a cold source for cold therapy on the human body. Simply put, it is an upgraded version of the full range of three-dimensional surrounded by ice, and we usually break the foot ice is a reason. Rapid freezing box can not only shrink blood vessels, reduce tissue metabolic rate, inhibit inflammatory response, but also be able to achieve the effect of pain, pain nerve conduction will be slowed down or blocked due to low temperature. And low temperatures also make the collagen fibers of the muscle stronger, protecting the injured muscle tissue.
Although it is called liquid nitrogen it is not liquid, but a gas. Generally in order to avoid hypothermia frostbite, athletes will not stay too long in the rapid freezer, 3 minutes is enough. Some people tease it seems that the little dragon lady is right, ah, cold bed can not only let the kung fu soared, but also to prevent the fire into the devil it.
But because the cost is too high, now not completely popularized the use of the future broken foot can go to the emergency freezer experience it.
Because the intensity of a soccer game is very high, physical consumption is also a lot. Soccer players tend to be extremely fatigued at the end of the game, the physical endurance of all aspects of the decline very quickly. Most of the muscles are in a state of mild inflammation at this time.
Emergency freezer, which is actually synonymous with liquid nitrogen, has a temperature as low as -196 degrees at atmospheric pressure. Many people will issue a question, the temperature in the box is so low, such a low temperature will not make the player more harm? In fact, we do not have to worry, because liquid nitrogen will not have direct contact with the players, when people go in will automatically produce an air protective film. So the real contact is the vapor of nitrogen, which is called the Leidenfrost phenomenon. In this way, the player is actually very safe. Many players today are using this aspect to decompress their muscles. Messi, Crow and other superstars need to do this just as much.
When using the emergency freezer, it can help the body to cool down quickly, is the blood vessel contraction, and make the body's metabolism lower, so as to achieve the effect of suppression of inflammation, such as injuries with ice cold compress is actually the same principle. Thus achieve the purpose of analgesia, which is a very effective way for these athletes.
Recovery
It is because the muscles of the whole body are in a state of fatigue.
Professional soccer players are prone to muscle fatigue, and prolonged fatigue can take a toll on the body and can easily lead to injuries. Prolonged fatigue can lead to injuries.
The freezer can be a good way to relieve muscle fatigue and avoid the effects of injury.
This freezer box is actually liquid nitrogen refrigeration, through liquid nitrogen to freeze. Instantaneous cryogenic freezing can be very good to relieve muscle fatigue and avoid muscle fatigue. Especially in the case of multiple games in a short period of time, athletes are prone to injuries, and such a method is one of the most scientific recovery methods in the world today.
Many people may think that instantaneous liquid nitrogen freezing will cause harm to athletes, but there is no need to worry about this happening. Although the liquid nitrogen will be more than 100 degrees below zero, but will not be in direct contact with the athlete's body, there will be a layer of air between the machine, do not have to worry about the occurrence of frostbite.
Low temperature can relieve muscle fatigue, reduce the occurrence of inflammation, can shrink blood vessels, reduce the body's metabolism, which is the most scientific recovery method in the world of sports at this stage.
