Li Dai suggested that Zhao Yue should specialize in 200 meters, and after Xue Li heard it, he immediately fell into silence. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Li Dai knew that Xue Li was seriously considering his suggestion.

Whether at home or abroad, there are not many sprinters specializing in 200 meters, and it can even be said that there are very few, and the vast majority of sprinters are mainly attacking 100 meters and running 200 meters at the same time.

In terms of influence, the 200m is of course far inferior to the 100m, and the 100m world record holder is known as the "fastest runner", while the 200m is not a good name.

At the same time, the 200-meter dash is also unlikely to appear in the IAAF Grand Prix, Super Grand Prix and Diamond League. According to the rules of the IAAF, only one of the same type of events will be selected to appear in the competition.

For example, the long jump and triple jump, high jump and pole vault, 800m and 1500m in the middle run, 5000m and 10000m in the long-distance run, can only appear in one event at a certain IAAF Grand Prix.

If the sprint event is chosen in the 100 meters and 200 meters, the former will definitely be chosen, how can there be no 100-meter trapeze battle in the track and field competition!

As a result, the 200m has become a mother's breed, and it is generally only seen in high-level large-scale events such as the World Championships in Athletics, the World Cup in Athletics and the Olympic Games.

There are few opportunities to compete in the 200-meter sprint, and those world-class sprinters will naturally not specialize in practicing the 200-meter, even if the athletes have a good talent in the 200-meter event, they will also focus on the 100-meter, because there are many opportunities in the 100-meter race, and only if they run the 100-meter well, they will have the opportunity to participate in more competitions.

Many people think that the 100 meters and 200 meters of sprinting are the same kind of sports, and the athletes who run fast in the 100 meters must be fast in the 200 meters; Conversely, athletes who run fast in the 200 meters will also run fast in the 100 meters.

In fact, this is only half true, and a runner who does well in the 200m will also do well in the 100m. However, runners with good results in the 100 meters may not be able to run the 200 meters.

The difference between 200 meters and 100 meters is that there is an extra 100 meters of distance, and this extra 100 meters is still a curve. The corners are the 200-meter difficulty.

Because of this extra corner, athletes must master three more techniques, the first is the curve starting technique; the second is the cornering running technique; The third is the curve-to-straight technique.

A curve start is different from a straight start, where you only need to rush forward with your head down, while a curve start requires you to control your body after starting. Athletes need to maintain their starting speed and control the angle of movement, and when they have both, it becomes a complex starting technique.

The width of a track is about 1.22 meters to 1.25 meters, and with the explosive power of a sprinter, if the body is not well controlled, it is easy to rush to someone else's track if you rush too hard at the start. If you deliberately slow down the start to maintain the angle, the starting speed will lag behind.

Sprinting is a sport in which you lose exactly 0.01 seconds, and if you start a few tenths of a second slower than others, you will lose more than half of the race, to put it bluntly.

An excellent start in a corner, the starting speed should be fast enough, the starting angle should be better, and you can quickly control your body to run in the corner after starting. Even a professional sprinter has to spend at least a year and a half to get a good start on a corner.

Running in corners is also a complex technique. When the object turns at high speed, it will bear a certain centripetal force, so the process of running in the curve is actually the process of controlling the body against the centripetal force.

At the same time, when running in corners, athletes must master the technique of running against the inside edge of the track.

In a 100-meter curve, the distance on the inside edge of the track is about 3.7 meters shorter than the outside of the track, and if you run the 200-meter course in 20 seconds, 3.7 meters is equivalent to 0.037 seconds. So when we look at the 200-meter sprint, the athletes will desperately run against the left side of the track in the corner, in order to save as much time as possible in the 0.03 seconds.

However, in the rules of sprinting, it is a foul for an athlete to step on the line and will be disqualified. It is impossible for athletes to keep their heads down to look at the sideline of the track during running, and with the stride and cadence of professional sprinters, if they want to run close to the inner sideline of the track without stepping on the line, they must go through a long period of training, and this technique also takes more than half a year of training to master.

In addition, the moment the corner enters the straight, which is another technical difficulty in the 200-meter dash.

After running on a 100-meter curve, the athlete already has the inertia of the curve, and the moment he turns into the straight, the first thing the athlete has to fight is the inertia of the body.

At the same time, at the moment of entering the straight, the athlete must keep his speed constant, and the skilled athlete can even accelerate at this stage.

The transition from a corner to the straight, good or bad, can make a difference of about 0.1 seconds, and it takes months of practice to perfect the technique.

Therefore, the sprint 200-meter event has few opportunities to participate, has high technical requirements, and is far less influential than the 100-meter.

However, Li Dai feels that the current Zhao Yue is very suitable to specialize in the 200-meter event.

When he was in the national team, Zhao Yue's main event was 100 meters, and he once ran 200 meters, and he had a certain technical background in the 200 meters event, so he didn't need to spend too much time practicing cornering techniques.

And with Zhao Yue's age, if he continues to practice 100 meters, it is impossible to have a chance to stand out, there are too many outstanding talents among young athletes, and compared with Yang Sijie's kind of genius, Zhao Yue is not competitive.

But the 200m event is different, and young athletes have to go through two or three years of training to master cornering techniques. Although Zhao Yue is relatively old, his skills are still there, and he only needs a short period of training to become an instant combat force in the 200-meter event.

What's more, Li Dai has detected that Zhao Yue's talent in the 200m event is better than his talent in the 100m event. Zhao Yue's talent in the 100-meter dash is B, and the talent in the 200-meter dash is B+, which shows that Zhao Yue has a strong ability to control his body, and he should be very good at running corners. In the national team, Li Dai did not find any athletes with a talent of B+ in the 200m.

Therefore, Li Dai recommended to Xue Li to let Zhao Yue practice 200 meters, and Li Dai believed that if Zhao Yue could seize this opportunity, he would definitely be able to return to the national team.

However, Xue Li is not very optimistic about Zhao Yue, and the 26-year-old "advanced age" makes Xue Li shy away from Zhao Yue.

Xue Li pondered for a few minutes before he spoke: "In two months, the training camp of the Asian Games will begin, and a large number of athletes will be recruited to participate in the training camp. ”

Li Dai immediately breathed a sigh of relief, he was very happy to help Zhao Yue and win such an opportunity for Zhao Yue to return to the national team.

Xue Li continued: "The training camp of the Asian Games will not only recruit athletes, but also coaches, so you have to participate. You haven't been home for a while, have you? I'll give you a vacation in a few days, go home and have a look, and when you come back, follow me to prepare for the Asian Games! In this Asian Games, we are fighting at home, and we must win at least one medal in the sprint event! ”
