After the preliminaries of the women's 400m event, it was already 6 o'clock in the evening.

The men's and women's 200m and 400m quarter-finals or semi-finals will be followed by a 200m and 400m final quota today, with the final tomorrow going on.

At seven o'clock, the first semi-final of the men's 400m freestyle is about to begin.

The registration rules for this national championship are that a maximum of three people can be registered in a province for a small event. The National Swimming Championships also has an element of selection in it, Su Yun, who was staying in the media area, looked left and right, and looked at the rostrum the most times, she was looking for any big people at the scene.

The leader's seat in the middle of the rostrum is temporarily empty, but Su Yun believes that in tomorrow's finals, there should be a few people in the Chinese swimming world who can talk about things.

The leaders of the Swimming Sports Management Center, the Chinese Swimming Association, the national team and other units are the figures who can talk about things in the Chinese swimming world.

Sitting in the crowd of reporters, Su Yun obtained a lot of information, and she learned that the athletes who performed well and were in excellent condition in this national championship will be selected for the new national training team to participate in the Asian Swimming Championships to be held in Dubai in November.

Su Yun looked at Du Ke, who was about to compete for a place in the 400 self-finals in the starting area, and secretly cheered for Du Ke: "Behave well, Du Ke, there are many people who are hiding in unknown corners and are paying attention to this championship." ”

At this time, the starting order sounded, and the first semi-final of the men's 400m freestyle began.

Duke was assigned to lane 6, and this time he directly started the stunt [Leap Thousands of Miles] and was in the lead as soon as he started.

After the first turn, Duke remained in first place, but the lead was not huge.

Zhang Lin in lane 7 caught up with Duke after the second turn, and the two went hand in hand, leading the swim.

Duke and Zhang Lin were divided into lanes 6 and 7, which shows that their results in the first round of preliminaries were not high. In the official competition, the runners are divided into lanes 4, 5, 3, 6, 2, 7, 1 and 8 according to the results of the preliminary round. The preliminaries will be based on the recent results of the contestants.

Du Ke forgot to start the jump stunt in the first round of preliminaries, and Zhang Lin seems to have retained his strength in the preliminaries.

In the current semi-finals, they have also let go of swimming, and if they retain their strength, it is possible to play with fire.

The players of the Nanyue team are not the top in the country, but the coaching staff of the Nanyue team can be described as an experienced team under the guidance and management of Lao Shuai Luo.

Coach Luo told Du Ke that he could basically enter the final within 3 minutes and 55 seconds of swimming in the semi-finals, and the old man would not open his eyes and say nonsense, and Du Ke also believed in the old coach.

Duke swam 3:58 (238) in the heats, and now he's going to be within 3:55 (235) of the heats, three seconds faster.

3 seconds faster is 2% faster, and that's how it is calculated linearly. But in swimming, including almost all events, the calculation cannot be so linear.

The closer the result is to the limits known to man, the more difficult it is to continue to improve, and it is not easy to swim 1 second faster, jump 1 centimeter more, lift 1 kilogram more, and so on.

Duke wants to speed up by 3 seconds, and 2% more effort is not enough, he has to further stimulate and even squeeze his potential, at least 20% more effort. Reflected in actual combat, the frequency of his arm strokes and legs is a little faster, a little faster, at least one-fifth faster. That's the actual effort it takes to be 3 seconds faster.

Because he had the target line in mind, Duke worked hard, he accelerated the pace and paddled towards the goal set for him by the coaching staff.

200 meters, halfway through.

Du Ke performed the [Dolphin Turn] stunt in the fourth turn, leaving Zhang Lin behind and leading the tour in the first position with the advantage of most of his body.

After the fifth turn, Duke used his last stunt [8 kicks] to extend the lead. He now particularly likes to do a series of stunts and dashes in the middle and late stages of the 400m race, rather than saving up for the last 50 meters.

According to the tactical guiding ideology of the coaching staff, this tactic is called "mid-stage strong attack".

There is no winning general in the sports arena, and it is impossible for any tactic to win all battles and be foolproof, and the mid-section strong attack is the same as the so-called tactics such as "forward raid, middle and rear suppression", "follow the whole process, and wait for the opportunity to capture the flag". If you can't attack in the middle section, it will be miserable, and Nima's physical energy will be consumed, and there will be great psychological side effects.

Du Ke is getting better and better at the rhythm of the mid-stage attack, similar to the battle online games he usually likes to play, it is shameful to be beaten on the street by the opponent, and it is a shame that the ultimate move is hung up without opening.

So before the sprint, Duke opened all the ultimates.

At this point the sprint bell rings, the last 100 meters.

In lane 6, Duke was in first place with a position advantage, Zhang Lin in lane 7 was second, and the other six competitors were not far behind each other, and they began to chase with a sprint rhythm.

Eight lanes are slamming, and eight competitors are fighting for a 50%-50% chance of reaching the finals.

In the last 50 meters, the situation did not change much, and Du Ke and Zhang Lin still maintained the first and second positions.

"Hurry, hurry, hurry!" When Hu Yucheng saw that Du Ke's situation was very good, he couldn't help but think that time was passing too slowly.

"That's it." Director Luo looked at the situation in the pool and said two words calmly.

Sure enough, at this time, Du Ke was the first to touch the wall and won the first place in the group, and then Zhang Lin touched the wall and won the second place in the group. The third and fourth players came from the eastern Zhejiang team and the northern Hebei team. The four will advance to the finals.

After the results came out, Du Ke nodded, quite satisfied with his performance just now, 3:50.02.

Zhang Lin finished second in the group with a time of 3:51.88, much faster than his first round of preliminaries, and it seems that he did retain his strength in the first round.

Zhang Lin looked at the results on the big screen, and then looked at Du Ke in the swimming lane next to him, he swam to Du Ke's side, pulled the diving goggles up on his forehead, and said to Du Ke: "Brother, learn from you, it's not polite words, it's very sincere." Team Nanyue, Duke Ke, I remember you. ”

Du Ke smiled: "Brother Lin is polite, I grew up watching you compete." Don't scare me, 'I remember you,' that's usually the villain's line. ”

"Really? Ha ha! Zhang Lin smiled heartily, "Then you should know that the holder of the 400 self-national record is me, 3 minutes and 44 seconds, I was in such good condition that year, and I accidentally brushed a record." Now, I can't break my own record. You work harder in the final and help me break it. ”

Du Ke shook his head: "Look at what you said, breaking a record is like buying a boxed lunch." ”

"Haha!" Zhang Lin was amused by Du Ke again, he patted Du Ke on the shoulder: "Dude is very funny, you can swim close to the A standard, of course it is worthy of my attention, so I remember you." Let's go, the referee is urging us to go ashore, and we'll see you in the final. ”
