"How does it feel?"

After the relaxation run of the warm-up, Zhang Pingqiu threw the coat back to Su Zu and asked him to put it on quickly.

The average annual temperature at the Haigen training base is 15.5 °C, and the lack of oxygen at an altitude of 0 meters is 17%.

"Excellent!"

Su Zu gasped softly, he had just run a few sets of super distance runs, but he felt that his breathing was not particularly tense, his lung capacity was full, and all parts of his body could feel full of strength and smooth operation.

"That's good!" Zhang Pingqiu smiled, "I'm afraid you don't adapt, this has something to do with your physique, if you don't adapt, we have to change places." ”

He could see that although it was a sub-plateau area, Su Zu was indeed very easy to train and run just now, and the main reason should be the environment, after all, he had been in a state of nervous tension for most of the past year or so, and now he has taken off the burden a little, and his condition and adaptation are very good.

Su Zu put on his coat and walked around the field again to calm his heart rate.

Before training Suzu in the sub-plateau, I had a few conversations with Li Zhizhong, including when he was at IMG Academy in the United States, and Loren Seagrave also mentioned this aspect.

For sprint events, the most direct improvement is in speed endurance.

Su Zu has been training in sprinting for many years, and his understanding of sprinting training is far from what he initially thought he could do as long as he could run.

Like Jamaican Lightning, Tyson Gay and Justin Gatlin, Su Zu has analyzed the technical characteristics of the three people, but they are actually fast in the second half.

Suzu has run several times with Justin Gatlin, and his current running style is that in the 100m event, he can distance himself from Gatlin in the first half of the race, but in the last twenty meters, he is often overtaken by Gatlin.

Gatlin's nine-point intensity in the first half of the middle and the last burst of running are often the last 10 or 20 meters.

Compared with Gatling, Tyson Gay and Jamaican Lightning have more speed and endurance in the second half of the race.

Both men ran from the 400m to the 200m and finally moved on to the 100m event. The ability to maintain speed was impressive, and even when most of the runners in the second half of the race began to slip, the Jamaican Lightning was able to accelerate again.

If you look closely at the races of several people, you can analyze that at the 2015 World Championships, Gatlin led 90 meters in front, but in the end he was still overtaken by Jamaica's lightning.

This is where speed endurance in the second half of the race comes into play.

For Su Zu himself, his current starting reaction is the key point that can be improved, and the other is the ability to maintain speed.

Take his best time of 9.79 seconds in the 100m:

The 0-10 meter time is 1.85 seconds

The time from 10 to 20 meters is 1.03 seconds

The time from 20 to 30 meters is 0.91 seconds

The time from 30 to 40 meters is 0.86 seconds

The time from 40 to 50 meters is 0.84 seconds

The time from 50 to 60 meters is 0.82 seconds

60-70 meters in 0.84 seconds

The time from 70 to 80 meters is 0.86 seconds

The time from 80 to 90 meters is 0.88 seconds

The time from 90 to 100 meters is 0.90 seconds

He ran at top speed, reaching 0.82-0.84 seconds at the top of the 50m-70m, but around 0.90 seconds in the final 80m-90m stage.

If you have better speed endurance, more speed and more speed, and stabilize your peak speed, you may be able to improve your personal performance even further.

In the sub-plateau area, due to the altitude, this altitude can not only ensure the needs of sprint anaerobic training, but also maximize the production of lactic acid, improve the body's lactic acid resistance, and thus improve the anaerobic exercise capacity, which is obvious for the improvement of speed endurance in the second half of the race. At the same time, training at this altitude is not too great because the body does not lose much water and fat, and it can be recovered by nutritional means.

These are all points that Li Zhizhong talked about when discussing the training plan with Yuan Guohua, Zhang Pingqiu, and other coaching staff, and of course, the specific training plan and training plan will not start until Li Zhizhong arrives in southern Yunnan.

In a way, it's also an attempt to train.

At Suzu's level, in addition to the regular physical, strength and speed training, the coaching staff has fallen into a situation where they don't know how to continue training.

What can be done is an ordinary training method. Optimize technique, improve running style, make up for weaknesses, but not many people have experience in fundamentally improving sprinting ability.

After all, the research theory still needs to be practiced in order to have real effect feedback, and the main problem faced by domestic sprinters is actually the lack of speed maintenance in the middle and second half of the race, that is, the speed endurance is relatively poor.

In the first twenty meters of the outbreak, there are actually many excellent seedlings in China, such as Chen Jian and Shen Yunbao, who have a good level of acceleration in the first half of the race, but it is difficult to stabilize the speed.

This also confirms that several of Japan's best sprinters are gradually moving from 400m and 200m to 100m.

The research group around Su Zu is also trying some relatively novel concepts. If it can be proven that training at sub-altitudes is effective for improving speed and endurance, it may also be included in the track and field team's sprint program in the future.

……

Haojiang Stadium.

Lin Bang stood outside the entrance of the stadium, thinking about the invitation call he received this morning, and a domestic Internet company wanted to poach him as the editor of the sports section in the past.

Now that the Internet is becoming more and more developed, print media reporters like him feel somewhat precarious. At the regular meeting, I have heard more than once or twice the words that sales are declining again.

Although he has not been in the industry for a long time, he has grabbed photos of Su Zu several times and reports about Su Zu's competition, which still attracted the attention of some peers.

"Xiaolin, you're here too!"

Lin Bang was thinking about the way out in the future, when a voice sounded next to him.

"Hey, it's Brother Luo, you're here this time."

Lin Bang looked at the visitor, and when he got on his face, he showed a professional smile on his face and greeted him warmly.

is the same as him, Rayong, are all reporters of sports media, but the focus of the report is slightly different, he is biased towards the track and field section, in the past two years, with the achievements of athletes such as Su Zu Liu Yangyu and other athletes, there are many people who pay attention to it in China, and all kinds of track and field events are also watched.

Rayong, on the other hand, is mainly biased towards football and basketball, and is a sports reporter, who looks up and doesn't look down, and is familiar with it after a few meetings.

"What, why did you come alone this time?" Rayong looked around Limbang.

"The travel expenses in our club are only much, and it would be nice to have one of them." Lin Bang smiled.

This is also the case, and the East Asian Games are actually nothing to look forward to. Well, Su Zu didn't come, fortunately Liu Yangyu was here, otherwise there would be no topicality. ”

The two were chatting happily at the gate of the stadium, occasionally exchanging some views on the game and news hotspots, when suddenly a few angry voices came from the side.

"Refund the ticket, let's go refund the ticket."

"It's too much!"

"Isn't that a lie?"

The two turned their heads to look over, and saw two girls negotiating with the staff of the venue.

Lin Bang and Luo Yong glanced at each other, and out of professional sensitivity, they unconsciously leaned to the side.

"Hey, classmate, are you from the mainland?"

The two girls talked to the staff at the venue for a while, then turned away rather angrily. And Rayong on the side had already stepped forward and stopped in front of the two.

"Yes, we are students studying in Haojiang." The two girls seemed to hear Rayong's Mandarin, and although they were still a little angry, they politely answered their questions.

"Look at the argument between you and the staff of the venue just now, what happened?" Lin Bang followed with a brisk step and asked.

"Are you journalists? It was too much for them, saying that there was a Suzu game, but we came over, and there was no one at all. ”

"Yes, we are journalists. Who told you that there was a Suzu competition? ”

"It was the staff at the ticket office, when we went to buy tickets, they said yes, and then we just had to ask at the entrance office, only to know that Su Zu had not come to participate in the East Asian Games at all. By the way, are you reporters, do you have Su Zu's signature and photo? ”

Hearing this, Luo Yong laughed and pointed at Lin Bang, "This reporter Lin may have, many of Su Zu's newspaper photos were taken by him." ”

Seeing the two girls looking at him, Lin Bang shook his head with a wry smile, "I really didn't bring it this time, and I will have a chance to mail you a few next time." ”

Several people talked for a while, and the two girls learned from Lin Bang that Su Zu had now started winter training, and the specific location was unknown to the outside world, so they were a little disappointed.

In the end, before leaving, they each left their mailing addresses to Lin Bang, telling them not to forget to send them photos, which caused Rayong next to him to laugh.
