According to the experience of modern people in this sport, one breath every four steps is the most appropriate. The thin physical education student www.biquge.info Pen Fun Pavilion has almost melted this breathing rhythm into his blood after a long period of training, so at the beginning of the run, he began to take four steps and one breath.

And Yun Lei's breathing rhythm in the running was chaotic enough. Sometimes it's three steps and one breath, sometimes it's two steps and one breath, and sometimes it's a deep breath...... It's really amateurish.

According to professional kinesiology, this kind of unrhythmic and unsmooth breathing will cause muscle tension, so that the heart and lungs and other organs are compressed, and you feel breathless. In other words, it is gasping for breath.

Gasping for breath increases intrathoracic pressure, impedes venous blood return, and decreases cardiac output. It will also aggravate the lack of oxygen in the body, so that the lactic acid concentration in the muscles will increase rapidly, resulting in the body feeling extremely tired.

Of course, in addition to the rhythm of breathing, Yun Lei's running posture is also very non-standard. Compared to the physical education major who led the way in front, it was far behind!

However, Yun Lei didn't come to turn himself into a professional athlete. While maintaining his running speed, he carefully savored the changes in his body's metabolism. As well as these metabolic changes, the resulting changes in the birth and death of bioelectric currents in the body.

For anyone, long-distance running is a sport that causes a pole effect on the body.

This extreme effect is due to the fact that the organ activity in the human body is relatively slow, so that the oxygen supply cannot keep up with the needs of the muscle activities of the limbs for a while, and a large number of metabolites produced in strenuous exercise cannot successfully complete the metabolism caused by dyspnea, weakness of the limbs, and extreme exhaustion of the body, as if the end of the world is coming, and the body is about to disintegrate.

This kind of pole effect is something that everyone has. It's just that athletes who have been training for a long time, such as the one who is soaking in front of Yunlei, will have a much lighter effect. And after this pole effect appears, people can only rely on their own willpower to survive this pole effect.

It is not until this pole effect has passed that the body feels relieved again. The so-called "second breath" will come.

If Yun Lei was just an ordinary person, then this pole effect alone would be enough to make him give up this 10,000-meter run. He doesn't have much physical exercise, and in Daiyu Mountain, he can barely survive this pole effect.

At this time, after the cloud thunder built the foundation, the body was washed by the aura of heaven and earth and became strong. In particular, the visceral organs, the ability to react and the ability to regulate the body are so strong that they almost break through the theoretical level of human medical research. Therefore, this pole effect is obviously not strong.

At the same time, Yun Lei's control of bioelectricity in his body has reached a new level. When the pole effect in his body appeared, Yun Lei's heart moved. Collects the bioelectric current flowing through the body. The rate of metabolism of the internal organs is balanced with the rate of oxygen supply to the body. This pole effect, with Yun Lei's active intervention, passed almost instantly.

Yun Lei ran two more laps with the students of the physical education department. After feeling that the body is no longer reacting, it seems that it has broken through the limits of human beings. You're welcome. His feet suddenly accelerated, and between three or two steps, he caught up with the pace of the physical education student who specialized in long-distance running, and then, between three or two steps, he left the physical education student who specializes in long-distance running behind him in great strides.

Originally, except for everyone who knew that Yun Lei was an immortal cultivator, seeing that Yun Lei was behind the athletes of this specialty, he was a few meters behind before he could catch up with the physical education student in front. I was surprised.

At this time, seeing Yun Lei's relaxed demeanor overtaking this professional athlete of the Department of Physical Education, he couldn't help but be stunned. The students of Mingjing University, who were not afraid of big things, shouted one after another: "Yunlei, run quickly, give him a ring! Give him a ring! If you can give him a ring, you will be awesome!"

There were also a few people who shouted to the buddy of the physical education department behind Yun Lei: "Hey! Dude, can you do it? Didn't eat? Hurry up and run! You are a major in the physical education department, you were overtaken by a Chinese department, are you ashamed? I will ask you if you are ashamed!"

Although this guy has been on the field for a long time and has rich experience in the game, he can be regarded as having a good psychological quality. As soon as he shouted this, he was still so angry that this guy almost fell out of the rhythm of four steps and one breath. I stumbled under my feet and almost fell.

He didn't understand how Yun Lei did it. It stands to reason that in a long-distance race, the rhythm and speed at the start basically determine the running rhythm and speed of the subsequent journey. This kind of running rhythm and speed is not impossible if you forcibly change it, but it will make the body feel very tired and physically exertional.

And, in general, only professional, strong top athletes can change speeds at will. In the second half of long-distance running, most people use perseverance to support themselves. It is simply not possible to do the shifting. As soon as the speed changes, the rhythm changes, and the body is estimated to be unable to hold it directly.

Therefore, this kind of overtaking, either Yun Lei gave up on himself, and after trying his best to surpass him and taunt him, his physical strength was exhausted. Either that, the clouds and thunder are hidden deeply. However, when Yun Lei passed by him, he didn't realize how tired Yun Lei was. The demeanor is extremely laid-back. Moreover, all the way forward, in a few breaths, he ran forward at the speed of a 100-meter sprint.

The confidence that this guy has cultivated for a long time is like a deflated ball, and it disappears without a trace in an instant. This doesn't make sense......

The people next to him were also stunned, although this group of spectators were not professional sports athletes. However, I have also experienced many physical education exams, large and small. I haven't taken the test in 10,000 meters, but I have always tested in 1,000 meters. After running past the first 1,000 meters, Yun Lei can still run so unrestrained and coquettish. It's definitely not something that ordinary people can do.

Generally speaking, in long-distance running, the last 100 to 200 meters is the stage of sprint acceleration. However, Yun Lei's leg run turned into a full sprint. When Yunlei ran to the finish line, everyone was stunned, and they didn't mean to cheer at all. The atmosphere was eerie and unusual.

One student was holding his mobile phone, looking at the timer on it, dumbfounded. Exclaimed: "This, this is a world record! The world men's 10,000-meter record is 26 minutes 17.53 seconds." However, classmate Yun only ran for twenty-six minutes and ten seconds!"

Everyone was in an uproar, Yun Lei's face collapsed, and when he ran, he ran happily. Still didn't hold back the steps. It makes people see some flaws.
