The liquid nitrogen that James and C Ronaldo often use can reach MINUS 200 degrees. What is the principle?

With the continuous development of science and technology, many athletes will use some high-tech equipment to help their bodies recover. For many high-level athletes, liquid nitrogen freezer has become a necessary rehabilitation equipment. Lebron james, cristiano ronaldo and other famous stars are equipped with private liquid nitrogen freezers. These top athletes will sleep in their own liquid nitrogen freezers for rehabilitation as soon as possible after the games. So what effect does the liquid nitrogen freezer have on athletes?

First of all, liquid nitrogen is a very common chemical product in industry. As an extremely low-temperature product, the lowest temperature of liquid nitrogen at room temperature can reach-200 degrees, which can greatly help athletes to recover their muscles. According to relevant professionals, low temperature can relax the tight muscles of athletes. Because the muscles are always in a state of tension during the competition, athletes will feel tired after the competition. Freezing can accelerate the metabolism inside the muscles, thus promoting the athletes' physical recovery.

At the same time, athletes' muscle inflammation can also be treated under the therapeutic effect of liquid nitrogen freezer. Through this treatment, athletes can quickly restore muscle activity in a short time and improve the recovery speed of muscles, which is a very efficient rehabilitation means.

However, if you want to use liquid nitrogen reasonably, you still need quite high professional knowledge. After all, the normal temperature of liquid nitrogen has reached MINUS 200 degrees.

This means that if you are not careful during use, you may directly frostbite your skin because of the low temperature of liquid nitrogen. At present, liquid nitrogen freezers are all injection systems that fill the warehouse with liquid nitrogen in advance. In fact, athletes are only exposed to the sprayed liquid nitrogen gas through atomization, rather than direct contact with liquid nitrogen.

Of course, the value of using this liquid nitrogen refrigerator is also very expensive. Each liquid nitrogen freezer costs more than one million dollars, and the cost of raw materials and personnel for each treatment may cost thousands or even tens of thousands of dollars, but for those top athletes, such expenses are actually nothing to them.

With the progress of science and technology, today's athletes can keep healthy in high-intensity and high-intensity competitions, which is why players like James and Cristiano Ronaldo can still maintain excellent competitive status on the field even if they are over 36 years old.
