Sun Jiashi touched the back of his neck and said, "How do I remember watching the news before saying that someone would get this disease if they ate unclean crayfish?" ”

The strong coach nodded and said, "I've heard of this too." To put it simply, rhabdomyolysis is the myoglobin in muscle cells, as well as small molecule substances, etc., leaking out of muscle cells, because myoglobin is relatively large, in the process of excretion, when it goes to the kidney, it will block the renal tubules and glomeruli, and the result is acute renal failure. Of course, I'm not a doctor, and I'm not a professional, so I can only tell you about this. ”

"Sounds terrible......" Xin Xiaotian suddenly admired this coach, she only thought that he was a sturdy big man before, but she didn't expect to know so much in terms of theoretical knowledge.

"We have to learn everything, it's not just that we can lead people by practicing well, but to be honest, it's not that I boast, there are not many professional coaches like me, and some coaches are halfway through, and they can also come out to lead people with a certificate after a few months of training, and now this industry is also ......"

The coach stopped halfway through the sentence, and probably felt that the rest of the words should not be said again.

Xin Xiaotian and Sun Jiashi were also interested, and they didn't continue to ask.

So the coach continued to popularize science with the previous words, and it seemed that only in this way would it be more formal to popularize science, and the tone was more like an endorsement: "There are also some people who have soft tissue inflammation around the knee after taking a cycling class, popliteal muscle spasm and edema, popliteal tendonitis and the like, all because the intensity of the exercise is too great and the body cannot adapt to it, so these problems occur." ”

Xin Xiaotian felt that the more the coach spoke, the more terrifying it became, and she couldn't understand what he was saying at all with those bunch of nouns, it seemed to be the part of the leg, right? Well, the system has loaded her mind with a diagram of the human body before......

Thinking of the physiological structure of the human body, Xin Xiaotian suddenly deviated from her thoughts and thought of another problem: since the amount of exercise of spinning bikes is so large, and if you don't pay attention to it, it will have so many negative effects, so ...... What if a female instructor with a cycling class comes to the Great Aunt?

With such a large exercise intensity, do you still insist on taking classes? But is it okay if you don't bring it? Looking at the class schedule, but they are all scheduled at a fixed time every week, and they must be more than this one, they must be rushing everywhere, so it should be unrealistic to take three or five days off every month, it's really confusing to think about it.

But this kind of question is not easy to ask others, let alone ask this male coach, so she had to be silently confused in her heart, and later she looked for the answer to this question on the Internet, but she did not find a definite answer.

Could it be that these female coaches who rushed to lead classes were all iron-beaten bodies?

Finally finished rolling her legs, Xin Xiaotian got up with relief, feeling that she had really experienced it in this hour today, all kinds of tiredness, all kinds of pain and soreness.

You must know that during the whole process of rolling her legs, Xin Xiaotian grinned in pain, and was embarrassed to make a sound, she turned the hot sweat of her whole body into a cold sweat, and the coach rolled very seriously, and rolled the front and back sides of the two legs with a foam roller without leaving dead ends, and the taste was really indescribable.

However, although it hurt for a while, my legs were really much more relaxed, and I was able to walk normally.

Turning her head, she saw a familiar figure, to be exact, the clothes were very familiar, it was the girl with a good figure in the first row during the cycling class just now, she was also alone on the side with a foam roller to relax her muscles, and her movements were very skillful.

The coach also glanced at Xin Xiaotian's line of sight, and then said: "You can also come over by yourself in the future to roll more legs with foam rollers, you can slim your legs, there are many related tutorials on the Internet, you can see for yourself, and you will learn it as soon as you learn it." ”

"Well, thank you." Xin Xiaotian really felt very grateful, so she asked again: "By the way, I've met several times, and I don't know what your name is, coach?" ”

"Oh, haha, I forgot to introduce myself, I'm sorry, my name is Huo Qiang, everyone calls me Da Qiang, you can call me whatever you want."

Sure enough, it's a strong name.

Daqiang spoke, put away the foam roller, Xin Xiaotian saw several foam rollers put together, some of them were the same as the one she used just now, the surface was flat, and there were a few protrusions with pimples on the surface, just like a large mace.

I thought to myself, if I used this to relax the fascia, how much it would hurt.

Daqiang saw that she was curious, so he simply popularized science again, and said: "We have several kinds of foam rollers here, this seems to be PE or EVA material, with moderate hardness, and is generally used by new members and girls." And then this one you can really call it a mace, haha, a lot of people say that, the flat is the rolling pin, and the protruding is the mace. ”

After that, Sun Jiashi began to follow Daqiang in class, Xin Xiaotian said goodbye to the two, returned to the locker room, took a shower, and gathered five or six sisters in the group as usual, used a few times to slim down fingering, increased a few points of training, and took everyone together, each of them gave themselves a massage, and at the same time took the time to record the weight of several people, even if they completed today's task progress, pack up and go home.

Back at her residence, Xin Xiaotian was a little curious and searched for tutorials on the Internet about foam rollers to relax muscles. There are a lot of them, all kinds of real-life action demonstrations, very detailed, almost every part of the body can be massaged with foam rollers.

There are also some text tutorials that analyze the wrong methods of foam roller massage and teach you how to use them correctly.

However, after looking at it for a while, there is confusion, and it is confusion in capital letters.

On the Internet, there are two completely opposing arguments, or opinions, on this issue.

One is the mainstream point of view, and most of them are reprinted from each other, which is the same as what Coach Daqiang said, thinking that this can help slim down, and it can roll finer and thinner.

However, there are opposing views, which are spoken in a stricter manner, saying that serious research has proven that doing so will only make the muscles stronger and stronger.

And also listed a few Xin Xiaotian has not heard of, but it seems to be an international professional fitness bull, who has been trained into a horizontal explosion type of huge body shape as an example, and with a sense of strength of real muscle photos, said that after training every day, they will use mace to carry out professional and deep massage to promote the growth of target muscle groups, that is, to find ways to enhance muscle strength, and to increase muscle circumference.

When Xin Xiaotian saw this, she was confused for the first time.

It's an indisputable fact that foam rollers can help relax muscles, and I really experienced it once, and the effect is really good. However, while helping the muscles to relax, can they roll finer and thinner, or do they roll stronger and stronger?

It's so much work......

Isn't it just to lose weight, there are actually two diametrically opposed statements? Which one should I listen to?

…… I don't know if anyone has done anything practical, using a foam roller on one leg and not on the other, and stick to it for a year or two to see what the results will be?
