"20.72 seconds, Zhao Yue's performance has improved again, and it has exceeded my expectations, Xiao Li, well done!" Xue Li was very satisfied with Zhao Yue's results in this test match. Pen, fun, pavilion www. biquge。 info

"Next, Zhao Yue's training plan will be changed." Xue Li continued: "We need to add some training content for relay races. ”

Li Dai nodded to show that for the athletes participating in the sprint event of the Asian Games, the 4x100m relay race is also one of their competition tasks. Therefore, before the race, the sprinters will be trained for the relay race.

In a relay race, you don't have to send the four fastest people on the field to win the championship.

For one lap along the standard course, the true straight is only about 160 meters, and the other 240 meters are in the range of corners. Of the four athletes in the 4 x 100 meters, the first and third runners are destined to run the entire course in the corner. Therefore, to run a 4x100m relay race, you need at least two runners with very good cornering skills.

From this point of view, the 200m athlete clearly has an advantage. The runner who runs the 200m has cornering skills, and the speed and explosiveness are also very good, and he can take on any shot.

In comparison, those 100-meter runners who do not have cornering skills can only run the second and fourth poles.

I only heard Xue Li continue: "The 4 x 100 meter relay race is generally only available in the competition, so there are not many training opportunities for the relay race, I think you have never been exposed to high-level relay training before, right?" ”

Li Dai nodded: "I learned some when I was in school, mainly in terms of baton handover skills." ”

"Let's talk about it, I learned those baton handover skills at that time." Xue Li has the heart to test Li Dai.

Li Dai thought for a while and said: "Mainly the upward lifting baton and the downward pressure baton, the upward lifting baton is the arm of the baton receiver naturally stretched back, the arm and the torso are about 40~50 degrees angle, the palm is backward, the thumb and the other four fingers are naturally open, and the tiger's mouth is facing down." The baton bearer sends the baton forward and upward into the hands of the baton-taker. The advantage of this method of passing the baton is that the action of the receiver stretching his arm backwards and downwards is relatively natural, and the movement of the baton bearer is also relatively natural and easy to master. The disadvantage is that after receiving the baton, the hand has been held in the middle of the baton, if you do not change hands and then pass to the next baton, you can only hold the front of the baton, which is easy to cause the baton to drop and affect the rapid progress. ”

"The downward pressure baton is when the baton is extended backwards with the arm at an angle of about 50-60 degrees to the torso. The wrist is internally rotated, the palm is up, the thumb and the other four fingers are open, and the tiger's mouth is facing back; The baton bearer passes the front end of the baton from the top to the bottom, and the baton bearer takes the baton. The advantage is that the baton receiver is convenient to run fast with the baton, and the baton transfer process is more accurate; The disadvantage is that the arm extension of the baton is relatively tense, and it is easy to make passing mistakes. ”

"When passing the baton, the first and third baton players run along the inside of the track and pass the baton to the left hand of the second and fourth basemen with their right hand, and the second baseman runs along the outside of the track and passes the baton to the right hand of the third baseman with his left hand."

Xue Li nodded: "Well, that's right, it looks like you're not lazy in school." However, in the official competition, we mostly use a hybrid baton transfer method, and arrange which baton handover method to choose according to the characteristics of each baton. ”

"For example, the athlete who runs the first baton, he doesn't need to think about the baton, he just needs to hand over the baton to the second runner steadily; The fourth baseman only needs to think about taking over the baton, and does not need to think about the problem of handing over the baton. As for the second and third batons, they have to take the baton and hand it over. Therefore, in order to reduce mistakes and save time, the second and third baton often use different methods of handing over the baton. ”

When Xue Li said this, his expression became serious: "But no matter what kind of baton handover method, the cooperation between the players is very important. A mistake in coordination will lead to the destruction of the entire game. ”

"I'll give you an example, before the rise of the Jamaican team, the U.S. team was the strongest relay country in the world, and for a long time, the U.S. team was the champion. At that time, the U.S. team didn't win the championship, and the only possibility was that there was a mistake in the game. ”

"In the world's top competitions, a good baton handover can save 0.1 seconds, while the level of Asian track and field athletes is relatively average, so a good baton handover can save more time, and can even improve the performance by 0.2 seconds."

Xue Li said this, as if reminiscing, and then asked: "Do you know which team won the 4x100-meter relay in the Asian Games eight years ago?" ”

Eight years ago, Li Dai was still a bitter high school dog, getting up early every day and greedy for darkness, with morning self-study in the morning and evening self-study in the evening. How can Li Dai have the time to pay attention to the Asian Games. So Li Dai could only guess: "I think it's the Dongying team, right?" Before the naturalization corps in West Asia, they stayed in the position of Asian sprint hegemon for almost thirty years, right? ”

"The Dongying team has monopolized Asian sprinting for 30 years, and the Asian Games eight years ago was almost the later stage of the golden generation of Dongying sprinting. But they weren't the champions of the 4x100m relay at the time. Xue Li spoke.

"That's the Saudi team? Saudi Arabia's sports are also a powerhouse in Asia. Li Dai said.

Xue Li still shook his head.

"The Iranian team? Qatar team? No, the Naturalization Corps should not have risen at that time. Could it be the countries of Central Asia? Or South Korea? Could it be that North Korea has released a big satellite, right? Li Dai guessed several countries one after another, all of which were sports powerhouses in Asia, but in exchange for Xue Li, he kept shaking his head.

"You wouldn't guess, it's the Thai team." Xue Li revealed the answer.

"The Thai team? I still believe that if Muay Thai wins the championship, in the 4x100m relay race, they can also win the championship? Li Dai was a little dumbfounded.

Within Asia, the sports of South Asian countries are certainly the weakest, where cricket and a sport similar to eagle catching chicks are popular.

The level of sports in Southeast Asia is not strong, but there are more or less one or two sports that can be played in Southeast Asian countries, such as badminton in Malaysia and Indonesia, boxing in the Philippines and Thailand, and so on.

But when it comes to athletics, Southeast Asia really has to stand aside, perhaps because of the constraints of race, and Southeast Asian countries have always made no achievements in track and field.

Therefore, hearing that the Thai team won the relay championship of the Asian Games, Li Dai was a little dumbfounded.

"Coach, it's the Asian Games, and the Thai team can win the championship? Did those strong teams not participate, or did they make mistakes and were picked up by the Thai team? Li Dai asked.

"The Dongying team, the Saudi team, including us, all participated in the competition at that time, and they all finished the game." A look of memory appeared on Xue Li's face, and he continued: "At that time, I personally led the team to participate in that game, and I witnessed the whole process with my own eyes. ”

"At that time, the four players of the Dongying team were all athletes who had reached the A standard of the Olympic Games, and even three of them had participated in the Olympic Games. In the Thai team, there is only one athlete with the Olympic B standard, and the other three have not even reached the Olympic B standard. ”

"However, the Thai team won and they won the game with a more tacit cooperation. The Thai team is very fluid. Whenever they run, the Dongying team is always able to chase the distance between them and the Thai team, and after each baton handover, the Thai team is always able to pull the distance away. ”

"I still remember the painful look on his face when Sasaki Akita, the ace of the Toei team, crossed the finish line, and even in the Olympics, he was able to make it to the semi-finals, arguably the strongest sprinter in Asia at the time, but in the Asian Games relay race, he could only settle for second place."

After Li Dai heard this, he also gasped with emotion.

The A standard for the Olympic 100-meter dash is 10.21 seconds, and the B standard is 10.28 seconds, which means that there is a difference of 0.7 seconds between athletes in the A standard and athletes in the B standard. At that time, Sasaki Akita, he could be called the No. 1 flyer in Asia, his speed was close to 10 seconds, and the best time of several other players in the Toei team was also around 10.10 seconds.

The Thai team has only one Olympic B player, which means that each of them has at least 0.2 seconds behind the players of the Dongying team. However, the Thai team was able to win the final relay championship, which proved that the Thai team was more than 0.2 seconds faster than the Dongying team in terms of passing the baton coordination.

Next to him, Xue Li opened his mouth and concluded: "I give you this example to tell you the importance of tacit understanding among team members in the relay race. Therefore, the training of the relay race is essentially a process of practicing cooperation and cultivating tacit understanding! And that's what we aim for in relay training! ”
