This 13 or 14-year-old miracle girl, a girl who has created a miracle of the alliance in only three months and a miracle of the world in one year.

The match between the two siblings has been confirmed to be between 6:00 and 9:30 p.m. After eating, the two of them leisurely cleaned the entire dormitory before setting off.

"It's said that it was six o'clock, but it actually started at 6:20, and the men's and women's teams only had two groups each, and the top eight with the best results entered the finals." The two siblings had already changed into swimsuits and sat on the bench to watch the live broadcast in front of the TV.

"Men or women first?" Seeing that the two of them have already changed their clothes, it is certain that they are definitely not competing together.

"Men first, because men are generally faster than girls, and men can save a lot of time."

Looking at the referees who came one after another on the referee's bench, Ye Yu pulled his waist tendons and began to warm up.

"The first athlete of the men's team, Hongdao Alliance Kirin, please go to the check-in office to check in." The arrival of the volunteers seemed to have been expected a long time ago, and after answering a sentence, he nodded to the seven and left.

Ye Yu had never tried to swim 400 meters in the pool, and at most 200 meters.

"Tingting, are you nervous?" Yu Xin looked at Tingting with an expression on the play.

"It's a little bit, he hasn't practiced after all. And freestyle is not his strong point in medley! ”

Fei Fei didn't think so, she believed in her brother's perverted skills.

"It's coming!"

Looking at the big screen intently, some people are nervous and some people are calm. There are also people who laugh and think strangely, such as Fei.

Medley refers to one of the competitive swimming events, including the medley relay and individual medley.

The 4×100m medley consists of 4 people swimming 100 meters in one style to complete the relay in the order of backstroke, breaststroke, butterfly and freestyle.

The individual medley competition is conducted in the order of butterfly, backstroke, breaststroke and freestyle. The individual medley is more demanding, and athletes need to highlight a certain event on a comprehensive basis.

The turning technique of the medley should take into account the connection between different strokes, and when the previous stroke ends with a turn, it is necessary to create conditions for the next stroke.

To measure the technical level of athletes, in addition to special, part-time ability is also an important basis. Some advanced swimming countries mostly use the medley as a means of comprehensive technical training, and on this basis, highlight special ability and concurrent ability.

Because the butterfly stroke has particularly high requirements for the waist and abdominal muscles and pectoral muscles, especially the strength of the waist and abdomen must be enough to ensure the smooth completion of the butterfly stroke, such as forcing out of the water. When people are tired, it is not easy to complete or is very reluctant, so the butterfly stroke is ranked first.

However, there are different views on the distribution of energy in the individual medley and how to train medley swimmers.

Some believe that breaststroke is an important style to improve one's overall medley performance, while others think that backstroke is important because as a good medleystroke athlete, there is often not much difference between freestyle and butterfly, and more difference between breaststroke and backstroke.

Fei was glad that she was at the end of the race, so that she had the opportunity to learn her brother's swimming skills.

Because of the requirements, athletes must swim the same distance (1/4 distance each) using four different strokes during the competition, in the order of butterfly, backstroke, breaststroke and freestyle.

"Why do you want to butterfly first?" Xuanwu asked strangely, he had always thought that medley was just to take any position you wanted.

"The reason for this ranking is that the butterfly and breaststroke are physically demanding, and the butterfly is the first of the four strokes. The correct thing is that the butterfly stroke can not make full force, only maintain a fixed frequency, the backstroke is a buffer swimming style, which plays a role in adjusting physical strength, the breaststroke is about to start to exert force, and the most important thing is freestyle, which is the most critical step in the medley, which requires full effort. "It's miserable, Ye Yu's freestyle is the weakest, and the weakest is the best and most needs to sprint with all his strength.

"How do you turn around? I've heard that the medley is not difficult, but the turn is hard. The white tiger bit the nail of his thumb with a terrifying expression.

"That's it, the butterfly swims 100 meters, and when you get there, the butterfly turns to the backstroke and swims back, and then the loop goes by! I think it's a little bit harder to switch from breaststroke to freestyle. Fei looked at the old brother in front of the screen carefully, and felt so handsome!

"Learning doesn't make you a nymphomaniac!" Mo Lin reminded.

After the sound, he began to carefully study Ye Yu's swimming style.

Arena

Butterfly swimming is his strong point, so he swims from the moment he enters the water to the water and swims in one go, and he does not take the lead without using all his strength from beginning to end.

The forward rollover is derived from the half-roll turn, and the speed of the turn is the highest of all backstroke turns.

During a backstroke turn, the shoulders can be rotated beyond the vertical plane until they are in a prone position, but the athlete must push off the pool wall in a supine position. When turning, a part of the athlete's body must touch the wall.

When the swimmer swims close to the pool wall, the body turns from the supine position to the prone position, and continuously does the forward rolling action, that is, the prone legs are supplemented by the dolphin legs, and at the same time the head is lowered, the chest is held, the buttocks are raised, and the straight legs are rolled forward around the horizontal axis.

The speed at which butterfly strokes are converted into backstrokes is also embarrassing, and Ye Yu is the only one in the team who knows how to roll forward and turn in the backstroke.

Most of the rest of the people use a grinding disc turn or a backstroke half-roll turn.

The grinding disc turning action is easy to learn, but there are pauses, the rotation speed is slow, and the range is suitable for beginner athletes only.

The rule of this method is to swim close to the pool wall, stretch the body, touch the wall with the palm of the right hand at the level in front of the left shoulder, and then quickly do the abdominal tuck and knee bending, and the body movement. At the same time, the right arm is pressed to the right with the palm of the hand, and the left hand is done in the water to do a reverse stroke, so that the upper body accelerates around the front and rear axes to the left, rotates 180°, stretches both hands forward from the water, and clamps the head with the two arms to do the action of kicking the wall and sliding.

Half-rolling, on the other hand, is the opposite of turning a millstone.

The backstroke half-roll turn is derived from the flat turn. The turning speed is faster than a flat turn, and the resistance of the water is reduced due to the swing of the legs through the air when turning.

It is only suitable for those who have a foundation but are not very capable.

The technique lies in the backstroke half-roll over the right hand touching the wall below the flat turn, about 30 cm below the water surface, and doing the movements of raising the head, chest and abdomen while touching the wall.
