After swimming 100 butterflies, he grabbed the handle on the wall of the pool, soaked in the water, and looked at the four timekeepers on the shore, as if asking about the results with his eyes.

The four timekeepers, Hu Yucheng and the other three assistant coaches got together at this time to check the watch.

Hu Yucheng: "My hand-counted result is 51.09 seconds, won't it...... Butterfly also broke the record? ”

Assistant coach Xiao Peng prompted: "Coach Hu, the electrometer score needs to be added more." My hand time was 51.18 seconds. ”

"Oh yes, I forgot about it in a moment of excitement, Duke...... I don't make evaluations anymore, but they teach me how to be a person every minute. As he spoke, Hu Yucheng laughed, "Old Yuan, where is your watch?" ”

Assistant coach Lao Yuan: "51.02 seconds, fast, really fast, if you don't break the record, it's fast." ”

The last assistant coach said, "It's 51.11 seconds on my side. ”

At this time, Director Luo also came over and asked Hu Yucheng, "How much?" ”

Hu Yucheng spread his palm and patted his left cheek gently, looked at Du Ke in the pool and said, "Hey, Luo Gui You, it's only been less than a minute, and I was slapped in the face." The average hand meter score of our four watches should be about 51 seconds 10 seconds, with our method of one or two decades, just take the conventional electric meter error, add 0.5 seconds, Du Ke's 100 butterfly electric meter score should be about 51 seconds 65. My watch is 51.09 seconds, and I forgot to count 0.5 seconds, I thought this kid had broken the Asian record of 100 butterflies again. ”

"If I'm not mistaken, the Asian record and the national record for the 100 butterfly are both 51.24 seconds, right? However, Duke can swim casually, and it is not bad to swim in 52 seconds, and it is no problem to participate in the national championship. It can't be compared to a genius like Phelps who swims in 50 seconds, but it is definitely enough to show off in China and even in Asia. ”

The current world record of 49.82 seconds in the 100 butterfly is held by Phelps, who was too far ahead of his peak in '09, and then he himself may not be able to swim into 50 seconds every time.

Director Luo nodded, and also glanced at Du Ke in the pool: "I think this kid is also a genius, I know that he will definitely swim butterfly, never thought it would be so fast?" Seeing that his butterfly arms and butterfly legs are quite skillful and efficient, was he instructed by a master when he was in the national team? Observe and observe, and then see if there is still this level in a few days? If he can maintain stability, he will help him do butterfly swimming results and report to the swimming association. ”

After finishing the matter, Director Luo yelled at Du Ke in the pool: "Du Ke! Go ashore and rest for 10 minutes, then continue 100 up. ”

Duke went ashore to rest, feeling that his physical strength was still very abundant, and the world-class endurance value was long-lasting.

Ten minutes after recovering, Duke got out of the pool and prepared to start swimming in the backstroke.

The backstroke is the only one of the four strokes to start in the pool, and Duke curls up facing the pool wall and grabs the handle on the wall of lane 4 with both hands in a ready-to-start position.

Hu Yucheng's starting whistle sounded, Du Ke let go, kicked the wall, quickly stretched his body on his back, and began to swim in a backstroke movement after sliding for a distance with the elastic force of the kicking wall at the time of departure.

Freestyle can be seen as a forward crawl, while backstroke is an anti-crawl. From the perspective of arm strokes and leg strokes, freestyle and backstroke are similar, 2-4, 2-6, which are commonly used leg beating rhythms.

There are some similarities between freestyle and backstroke, so when Duke first learned to swim as a child, after learning freestyle, the second type of swimming style was the backstroke, and his default skills included freestyle and backstroke.

But don't think that freestyle turning 180 degrees and lying up on your back is backstroke, the two have a similar rhythm of leg strokes, but also have their own technical characteristics.

Some people think that the backstroke is the most comfortable, comfortable and relaxed swimming style, in fact, in the swimming competition, the backstroke race and the casual backstroke playing in the water are completely different feelings, and the backstroke race is very tiring, much more tired than freestyle.

There are a lot of old men, old ladies, uncles and aunts in the park who exercise in the morning, they like to walk backwards, and they can exercise very comfortably, but let them sprint backwards to try?

The backstroke is the rhythm of the sprint backwards, and it is the only stroke in which you can't see the front of you.

At this time, Duke was almost 50 meters to the side, ready to turn around.

When swimming in the backstroke, the athlete can't see the front of him, how do you know that you are almost at the pool wall?

Flags will be hung over the pool walls at both ends of the stadium, and the backstrokers will swim under the flags to know, oh, there are still 5 meters to the side.

The green flag was also hung above the training hall of the Nanyue team, Du Ke looked at the flag above and knew that it was almost to the edge, he quickly turned his head to the side and glanced at the back, and confirmed the pool wall visually, and then approached the wall, rolled sideways, kicked the wall, and slided, making a standard backstroke turn action.

Doucle's body is fully stretched and streamlined, and he slides underwater after kicking the wall, and he doesn't turn around this time without opening the dolphin turn, and in the stunt CD, it is a hard turn.

After gliding a short distance underwater, Duke felt that his gliding speed was approaching swimming speed, so he came out of the water and began to swim in a rhythm of 2-6 arm strokes and leg strokes.

Like the butterfly, Duke swims the backstroke very standardly, but he doesn't do it as a textbook, he wants to make internal results, impress the coach, and get the coach to support him to participate in the full stroke competition, which is a "particularly crazy and incredible" behavior. If the coach doesn't sign up for Duke, then Duke can't do anything, he can't go to the championship in his own name.

In fact, Du Ke's current status in the provincial team is still quite high, 100% of the leader. It's just that he suddenly threw out an unbelievable proposal of "full swimming style and full distance" today, and the coaches had to be suspicious, because no one had ever done this kind of thing.

Duke wants to prove that he's not bragging, and he swims the internal test as if it were an official competition.

After turning and sliding out of the water, connecting to the rhythm of swimming, Duke performed the only stunt [Big Water Wheel] that can be used so far.

[8 kicks], only applicable to freestyle, this novice welfare stunt is given for free, and Duke knew it when he first got it.

[Dolphin Turn], which can be used for full strokes, but Douc had already used it once 10 minutes ago.

[Leap a Thousand Miles] is a starting stunt, except for the backstroke, other swimming styles can use this stunt as an opening skill.

[Large water wheel], which can also be used for full swimming strokes.

Therefore, Duke knows that only freestyle can be used in all four skills, butterflies and frogs can be used in three skills, and backstroke is the least, and only two skills can be driven by dolphin turning and big water wheel.

Duke, who was in the backstroke, turned on the stunt [Big Water Wheel] and began to sprint.

"Look at it, Brother Du is excited!"

"Adu is really an all-rounder, and he can be so fierce in the backstroke."

The onlookers on the shore were amazed, they were also professional players, and in a game, for a short period of time, they would also gather fire and accelerate to sprint, but the acceleration was not as amazing as Duke's.

By this time, Duke had touched the edge of the wall and swam 100 backs.

The hand-counted score of the four coaches on the shore was +0.5 seconds, and Duke's 100 back swim just now was about 53 seconds, not far from the national record.

"Coach Luo, it seems that Duke can also sign up for the backstroke. Do we still test breaststroke......"
