"Yang Yao has advanced to the semifinals!"

On the morning of August 24, the indoor check-in area of the Olympic Stadium in Athens.

Yu Weili was guiding Ye Qin to warm up on the edge of the venue, when he saw his colleague Yuan Mingfu running towards him with a happy face.

Yuan Mingfu, who was once the first Chinese men's 100-meter electric time record, is currently the coach of the national track and field team, and has high attainments in both sprinting and relay events.

"What's the grade?" Yu Weili's face suddenly showed a look of joy, and he hurriedly asked.

Men's 100m and men's 400m two events, Chen Jian and Ye Qin both stopped in the first round, now the only event is the men's 200m, as a track and field coach, former track and field athletes, although Yang Yao is not an athlete he leads, but in the sprint event, Chinese players can advance to the next round on the Olympic stage, which is enough to make him excited.

"20.59 seconds! Fourth in the group! Yuan Mingfu smiled and reported Yang Yao's promotion results and rankings.

Yu Weili nodded and said with a smile: "It's very good, I can stabilize my mentality in the Olympic Games, Yang Yao has fully played his level." ”

"It really played well, Yang Yao's promotion this time is to become the first Chinese male sprinter to hear the second shot." Yuan Mingfu smiled and suddenly glanced at Ye Qin on the warm-up track, "What about Ye Qin, can we have two players advance to the semi-finals this time?" ”

This morning is the men's 200m preliminaries of the Athens Olympic Games, there are a total of 7 groups in the preliminaries, because it is a four-shot victory, the top four in each preliminary group directly advance (Q), and then add the best four players in the remaining players (Q) A total of 32 players will start the second round of the semi-finals.

Yang Yao is the first group, and the preliminaries start at 10:35 a.m., while Ye Qin is the sixth group of the preliminaries, and the time of the game is 11:05, a difference of half an hour.

At this time, Yang Yao's first group of preliminaries was over, and the pre-game warm-up of Ye Qin's sixth group of preliminaries was not over.

"Ye Qin should still have a chance."

Yu Weili glanced at Ye Qin, who was doing starting training, his pupils shrunk, and his face became a little dignified.

The men's 400m race has ended, and although Ye Qin was eliminated after only the first round of preliminaries, his performance in this competition is enough to attract Yu Weili's attention.

And through the first round of preliminaries of the 400 meters, he can also see that Ye Qin is in good shape, and there is still a chance to advance to the second round of the semi-finals like Yang Yao.

"It would be great if both of them could make it to the semifinals, or even the semifinals!"

A smile rose on Yuan Mingfu's face, for a coach who was a sprinter, like Yu Weili, he wanted to see the breakthrough of Chinese athletes in the field.

This point in time is the most difficult time for men's sprinting in China, the men's 100-meter record has not been touched since 97, and the men's 200-meter record has been broken by Ye Qin at the World Youth Championships from 96 to this year.

In the past few years, in the international competition, the entire domestic environment in the men's sprint event has not thought about the results and progress, always ended in failure again and again, not to mention the world-class competition, that is, the Asian Games, Chinese players have not won the men's sprint single championship for 30 years.

In the national team, from Feng Shuyou to Yu Weili to Yuan Mingfu, all of them are anxious about these, but the domestic local team and the national team are stumbling together, attaching importance to domestic competitions and ignoring international competitions, so that the overall level has not improved.

This is also the reason why when Ye Qin broke the men's 200-meter national record, the coach of the track and field team organized a meeting as soon as possible, and he must be recalled to China to participate in the Olympic Games immediately.

There are too few newcomers to emerge, and they need too much fresh blood to replenish them.

Being able to have one or two Chinese male sprinters in the Olympic Games to break into the second and third rounds of the competition is already a shot in the arm for the track and field team.

For example, the men's 4×100m relay event, which wanted to participate in the World Championships last year, did not know how many reasons were explained during the period, and were approved at various levels. Coupled with psychological inferiority, how can there be a good performance without good training. I often go to several people to practice and can't get a point, and in the team, I can't raise my head like a stepmother.

This is the current situation of the men's sprint event, the worse the results in the international arena, the less attention they get, the worse the results, and so on, it is completely beyond the support that several of their track and field coaches can give.

"Old Yuan, you go to the stage and wait for me first, don't talk to Ye Qin about Yang Yao's promotion."

Yu Weili looked at the warm-up track, and after Ye Qin completed several sets of starting warm-ups he asked for one after another, he had already walked back and turned to Yuan Mingfu.

"Okay, I'll go and see the other sets."

Yuan Mingfu nodded, Ye Qin is now an athlete under Yu Weili, in this kind of competition, he can come over and talk to Yu Weili about Yang Yao's results, but it is naturally inappropriate to say to Ye Qin in person.

They are all veteran coaches, so they naturally know that the competition of athletes is not only abroad, but also in China, in the team and their teammates, and it is not advisable to increase the pressure in vain.

After Yuan Mingfu left, Yu Weili watched Ye Qin come over, and then beckoned to him, "Are the joints completely open?" ”

Ye Qin made two abdominal jumps on the spot, raised his legs slightly, and then nodded, "It should be about the same." ”

"Put your back on me."

Yu Weili glanced at Ye Qin carefully, suddenly turned around, his back arched slightly, and said to Ye Qin.

"Huh?" Ye Qin's eyes were slightly puzzled.

Yu Weili patted his back lightly and urged, "Hurry up!" ”

The muscles in the corners of Ye Qin's eyes twitched slightly, a little puzzled, but he still leaned his back on Yu Weili's back.

Yu Weili grabbed Ye Qin's arm, but his whole body stretched the joints of his back and shoulders, and then let Ye Qin stand up, and first stretched some other muscles and joints for him.

"Today is not 400 meters better than last time, and the race that day was in the evening." Yu Weili said while talking about Ye Qin's left and right arms crossed, pulling a little harder, and said, "In the morning game, it is very important to warm up and stretch muscles and joints, I don't know if your previous coach told you, but you have to pay attention." ”

"Coach, why is that?"

Ye Qin felt that his body was gradually stretched and stretched by Yu Weili, and his body felt relaxed by massage.

Nie Fangping had told him before that his competitive state at night would be at its peak, and his own training and competitions had felt that his state at night seemed to be better.

"This is exercise physiology." Yu Weili explained slowly while giving Ye Qin a simple muscle stretch.

For many spectators watching the competition, there will always be some wonder why the time of the men's 100m competition like the Olympics is placed in the evening, and the time is even more at 11 o'clock in the evening like the men's 100m final that ended on the 22nd. There is also the men's 400m race, which takes place at 9 p.m. in the evening, both in the preliminaries, semi-finals and final.

This is because biorhythms affect human performance, including athletes' performance. Whether it's athletic events such as sprinting and swimming, or skill events such as badminton and tennis, athletes perform better at night.

For high-intensity, short-term anaerobic exercise, the impact of race time on speed, endurance, explosiveness and other aspects can be as high as 20%. The reason why athletes perform best in the evening and evening is due to the cyclical changes in the body's basal body temperature. Athletes perform best when their body temperature is highest.

This is one of the reasons why many of the Olympics and important major events are held in the summer. Of course, warm-up exercises and hot and humid environments can change body temperature.

On the other hand, the secretion of hormones is related to the day and night cycle, which affects sports performance. For example, male hormones and cortisol can change throughout the day, and male hormones can accelerate protein synthesis in muscle cells and promote competitive performance. To put it simply, the ratio of male hormones will increase at night, which is easy to improve the performance of athletes.

Of course, athletes with different biological rhythms have different rules of competitive performance, and professional athletes also need to be trained to adjust their circadian rhythms.

"By the way, you've already seen the list of games, right?"

After a simple muscle stretch, Yu Weili suddenly asked towards Ye.

Time has passed little by little, and the players of the sixth group of the preliminaries will be checked in by name.

"I've seen it!" Ye Qin shook his body lightly in place, relaxing his muscles.

"Don't put too much emphasis on your opponent, just go all out!" Yu Weili reassured again.

Ye Qin nodded, a spark hidden in his eyes.

In his group of men's 200m preliminaries, he did not expect to meet another old opponent so soon.
