On the morning of June 1, after a sports news broadcast on CCTV 5, it instantly triggered a huge response.

Yesterday, in the men's 100m at the New York Grand Prix on 31 May, Jamaican flyer Yusse Bot broke the men's 100m world record of 9.73 seconds, which was held by Yechin less than a week ago, with a time of 9.72 seconds.

After Ye Qin tied the world record with a time of 9.74 seconds at the Osaka Grand Prix, and then broke the men's 100-meter world record with a time of 9.73 seconds, in a short period of time, Ye Qin has already made everyone pay attention to his performance on the eve of the Olympic Games.

But even with such a strong performance, on the last day of the end of May, someone once again pushed the men's 100m world record forward by one hundredth of a second.

At this time, many people really know how to do it, and those who know the men's 100-meter world record can't help but sigh that the world's new generation of sprinters has really risen to the top.

Over the past few decades, the men's 100m record has often taken years to move a small step forward, starting in 1968 when Hines set the men's 100m world record in 9.95 seconds, when Hines set the first 10-second electronic timer. By 1983, it took 15 years for Smith Kevin Smith to run 9.95 seconds to become a new world record.

This was followed by Carl Lewis in 9.92 seconds in 1988, Leroy Burrell in 1991 in 9.90 seconds, Carl Lewis in 1991 in 9.86 seconds, Leroy Burrell in 1994 in 9.85 seconds, Donovan Bailey in 1996 and Maurice Green in 1999 in 9.79 seconds.

Among these legal results recognized by the IAAF, except for the men's 100m world record in 1991, when Leroy Burrell and Carl Lewis both broke the world record, basically the world record changes are made on an annual basis.

In less than a year since Asafavir broke the world record in Rieti, Italy on September 9 last year with a time of 9.74 seconds, there have been three changes to the world record, the most recent two of which have occurred within a month, which has to be surprising.

Yechin's two times of 9.74 and 9.73 seconds, and Yusse Bott's 9.76 seconds and 9.72 seconds, both announced their strength in the men's 100m event in this time.

At this time, the outside world originally thought that this year's Olympics would continue the triwizard showdown between Yechin and Asafarville and Jason Gaby at last year's World Championships in Osaka, and many turned into a four-strong battle of Yechin, Yusse Both, Asafarville and Jason Gaby.

Among them, Ye Qin and Yusse Bot are the most favored by the outside world because of their performance this season.

This year's Al-Asafavil has been injured since the start of the year and has yet to show his face in any of the games, and no one knows how he is doing.

Jason Gaby has been training and racing early this year, but his current best time is 9.85 seconds at the New York Grand Prix, which is very good, but it does not break 9.80 seconds, which is still far from Yechin and Yusse Bot.

In an office in the General Administration of National Training, Yu Weili, Yuan Guohua, Li Qi and other coaches sat together, discussing Yusse Bote, the world flyer who was born in the men's 100m event, and everyone looked very solemn.

"If you want me to say, it's better to reduce the pressure on Ye Qin, when it comes to Ye Qin and Yousse Bote, athletes of their level, basically the level will not be too different, the main thing is to see the live performance." Professor Li Qi of the Physical Education Department of Mizuki University was the first to speak, he was originally the coach of Gu Kai and Zhang Peimeng, and later the assistant coach of the relay team, and he was very familiar with the track and field team, whether it was a relay athlete or Ye Qin.

"That being said, but the comparison between Yusse-Bot's technical characteristics and Yechin's, we feel that we should still discuss it in detail." Yuan Guohua frowned slightly and said.

Ye Qin broke the world record in the men's 100 meters, and this impact may be just a sentence of "lying down" and "" for ordinary people, but for the Chinese track and field community, for these track and field coaches, it is a completely different level of shock.

It is an innovative cognition from concept to thinking and technology, I believe that the yellow race can create miracles in this project, even if six or seven of them may be black runners after a race, but as long as a yellow person sets a miracle of the 100-meter world record, it can inspire many people to strengthen their beliefs.

What everyone is frustrated now is that Ye Qin's men's 100m world record was really a little too short, and it was only a week before and after it was broken by Yusse Bot again.

This made many track and field coaches who had just mustered up their energy and felt very interesting, and they inevitably felt a little powerless.

"I watched the video of Yusse Bot at the New York Grand Prix, but it was very good, before the research center used a single frame time processing and calculation method to loop the slow motion of Yusai Bot and Yechin, and then compared and measured the technical characteristics of the two frame by frame, Yusai Bot is too tall, the center of gravity is too high in the process of bending to leaning over, this is a shortcoming, everyone knows that in a world-class race, a slightly careless start can cause a series of reactions and lead to the final race loss."

"But I saw that Yusse Bor's start was very fast, and he was a few dozen meters ahead." Hearing Yuan Guohua talk about the technical differences between Ye Qin and Yusse-Bote, Li Qi couldn't help but say aloud.

"Well, that's right." Yuan Guohua nodded, "The starting method specified to him by Yusai Bote's coach is very effective, with a quick reaction and a strong back pedal to quickly get rid of the static state of the body, although the first few steps are a little shaky, but by increasing the momentum and strength in the starting and acceleration phases, the technical action link of gradually lifting the upper body is reduced, and the upper body is lifted 2-3 steps earlier than other athletes, making full use of the advantages of running on the way, so that only 3-5 steps are needed to determine the advantage." ”

"There is still a difference between this technique and Yechin's starting style." Li Qi bowed slightly, simply put, Eusy-Bott is tall and has long legs and fast cadence, but because of his size, he can't start particularly quickly, but in order to ensure that he can take advantage as much as possible after starting, he uses to lift his upper body as early as possible, so that the rhythm of the race enters the running link on the way, and reduces the acceleration running link of bowing his head and rushing.

Ye Qin's current starting method still belongs to grasping the acceleration of running, so that the body can rush up the speed, the two ways can not say who is superior and who is inferior, the specific depends on the athlete's physical fitness and other hard conditions.

This is the timely understanding and research of Yusse-Bot after the emergence of Yusse-Bote, who has actually seen the data of Yusey-Bot before, and in the men's 200m event, it is very good, but many times, no one can imagine that Yuse-Bot can grow so rapidly.

Leaping past Asafavir and Jason Gaby to become Yechin's number one enemy.

"It's useless to discuss too much about technical things, the key is Yechin's mentality." Yu Weili saw that Yuan Guohua and Li Qi were talking hotly, waved his hand slightly, and did not continue to discuss at the technical level, but said, "In this way, everyone can't discuss anything here, let's go to the track and field to have a look." ”

"It's been a while since I've seen how they're training."

Li Qi nodded, he is a professor at the Physical Education Department of Mizuki University, although he usually has a job on the national team, but Mizuki University itself has a lot of things waiting for him.

"Then take a look." Yuan Guohua naturally did not object, the news that Yusse Bot broke the men's 100m world record had been transmitted back to China earlier, and Ye Qin must have known it for a long time.

This time, he didn't go to talk to Ye Qin alone, the main aspect was that he was a little panicked in his heart, and he also felt a sense of crisis, and he didn't want to show his timidity in front of the athletes, so he discussed it with a few other people first.

Yu Weili is quite confident in Ye Qin, and at this time, in his opinion, it is not the time to discuss the technical aspects specifically, but he cannot be weak in mentality.

A few people said, did not stay in the office for long, and soon came to the track and field of the training bureau.
