What would these two siblings do if they didn't have to train every day? So it is estimated that the answer is that she will spend a day in the swimming pool for two sessions. Why? What else can you do, study how to swim fast! Otherwise, the two brothers and sisters compete to see who is faster, of course, if Ye Yu doesn't release the water, Fei has never won.

They studied the history of butterfly strokes and found that in order to increase the speed of the breaststroke, existing athletes swung their arms forward from the air after the stroke to look like a butterfly spreading its wings, hence the name butterfly. At that time, this new swimming style was often used as the same event as breaststroke, and was collectively referred to as the diving stroke. It was not until 1956 that it was separated and used as a separate project.

"But I couldn't see anything in common between butterfly and dive." Mo Lin held his chin and played boredom with water polo in his hands, he had swam for so many years and didn't realize that there was such a history at all.

Ye Yu came out of the locker room with his swimming cap thrown off, full of disgust, "You guys have never studied the history of your own specialty, how can you make progress?" We know all the history on one side, so that we can make successful progress. ”

This made Fei shudder, she had never found that her brother had such a hole in his brain, as if she had been understanding the so-called historical things all along! Where did Ye Yu investigate. wanted to expose the result and was tightly covered in the next second, Ye Yu saw everyone with a smile, and softly gritted his teeth in Fei's ear.

"Hey, she's still sick, don't make trouble." Mo Lin cared about pulling the person to his side and tightly protecting the person in his arms.

"The first group of participants, please go on the field and prepare." Volunteers appeared at the door with a large pile of papers to remind them.

Fei dragged his long coat and turned out, "If you win first, I'll tell you what you want." ”

"What information?"

"Do you have any information you would like to know about all the history of butterfly swimming?" Fei asked Mo Lin temptingly, the historical information she knew was not the kind of history that ordinary people knew, and she was a moving universal treasure book.

"I wonder if there is a history of athletics?" Mo Lin carefully sorted out the corners of Fei's clothes, and an unintentional question actually aroused Fei's enthusiasm.

"I really know that I'm not like my brother who carries a computer every day, and he turns on the computer to check if he has something, and I completely belong to the brain extraction." Fei said happily, "Do you want to know?" ”

Mo Lin raised his eyebrows and nodded.

"Athletics is called athletics, which is the full name of athletics, track and all-around competitions. Modern track and field sports are classified differently, mainly including race walking, running, jumping, throwing and running, jumping, jumping, throwing part of the all-round sports, a total of more than 40 items. Among them, the event calculated in time is called track race; Events in which results are calculated by altitude or distance are called field races. "Running, walking, jumping and throwing are the basic skills of human life and the most basic form of athletics in athletics. These natural sports and skills have a very close relationship with the learning and mastery of various techniques of track and field, each event has a master, how high you can go depends on whether you understand the history and development of these sports, find the development in history, Fei's freestyle movements are from the advantages of history.

The reason why Fei's freestyle is so fast is due to history and development.

"Sure enough, it's the sister of Baibaoshu, it's really good, and she can actually memorize all the history." Yu Xin applauded in admiration, how many memory memories are in this head.

"It's out." Fei excitedly pulled Mo Lin's sleeve, her brother's swimsuit seemed to be bought by her! Handsome! The butterfly is the youngest of the four sprint swimming styles, and it is also the one that tests the arm strength the most.

Ye Yu stood on the departure platform with his cool glasses, looking at the front of the pool seriously. When the starter issued "everyone in place", Ye Yu solemnly kicked on the edge of the departure platform in front of the departure platform. After the flute was issued, Ye Yu almost replicated Fei's take-off and sliding movements.

"Wow, dude, you stole my tricks." However, this technique is also very effective for Ye Yu, men's competition is not as good as girls, men's physical strength can be limitless, so what Ye Yu has to do is to win the advantage of others in the jump.

Jumping out of a super long distance, coupled with Fei's loach sliding method, Ye Yu was at least 2 meters ahead at the beginning.

When the arms are separated outward after entering the water, the palms are turned to the side, and then turned to the side to stroke downward, at this time, maintain a high elbow posture, so that the hands and forearms form a better opponent position, and start to stroke from front to back, from the outside to the inside, and the elbow flexion reaches the maximum when rowing to the abdomen, and the two hands are very close to each other. The thighs come out of the water with the help of the inertia of the stroke. Leg movements, legs together to play up and down in waves. The leading position made Ye Yu nervous, and when he turned around, he copied Fei's underwater turning action again.

"My brother really copied my skills perfectly, this stinky man! Wait a minute, if you can't win, I'll kill him. Fei leaned on the wooden chair unhappily and looked at Ye Yu, who was two positions ahead in the pool.

Everyone held back their laughter, Ye Yu was finished. actually stealing the skills of his own sister, if he is accidentally copied by others to his own sister, he will be stunned again, and he will sink in the pool every day! Eldest brother!

In the freestyle and backstroke, the athlete can touch the wall with one hand when reaching the finish line, while in the breaststroke and butterfly, both hands must touch the wall at the same time. This is not a difficult thing for Ye Yu. All swimmers' results and rankings are determined by an automatic timing device, and when the athlete starts, the pressure plate on the starting platform records the data. Each lane is fitted with contact wall plates at both ends, and when an athlete touches the wall, it is also recorded. Since the contact wall plate and the starting table are connected to each other, it is possible to determine whether an athlete has entered the water after a teammate has touched the wall.

"My brother's movements are exactly a copy of me, but how do I look so weird? Something seems to be wrong. Fei seemed to have discovered something, and his brain began to repeat the action that Ye Yu turned around just now. There seems to be something unpleasant about the eyes, but it feels strange.

"What's wrong? How can I not feel that something is wrong? Mo Lin glanced at Fei and then at Ye Yu, who had already touched the wall, what was wrong? How could he not feel it.

Fei shook his head, got up and walked to the lounge, "I think my brother is giving me the conditions to find out what he has a problem with, I think my swimming style can still improve, I'm going to go to him and ask." ”

"Wait a minute!" Mo Lin hurriedly packed Fei's package and chased after him with his schoolbag.

"Let's go, go steal the teacher, won't you? I think it can make us better. Yu Xin smiled and followed.
