I want to learn long jump!

IAAF President Diaz put down the newspaper in his hand and raised his head to say, "Have you read this news? Zhang Guan wants to participate in two projects in the Golden League at the same time."

The man sitting in front of Diaz called Gabriel Dole, an IAAF official, replied: "From the current Zhang Guan's ranking on the 400-meter sprint event, he Eligible to sign up for the 400m sprint in the Golden League. "

Diaz and Dole fell into silence at the same time. Since the Golden League, this has never happened.

In the rules book of the IAAF Golden League, only one item of a small type of item can appear in the game. For example, throwing the javelin, discus shot put, and hammer throwing will choose one as the competition event; jumping high jump, pole vault, long jump, and triple jump will also be chosen as the other competition event; 800 meters middle run and 1500 meters middle run are also chosen as one event in a competition event; the 5000m run and the 10000m run are selected as the competition event and so on.

Of course, each substation will temporarily add some new items, but only calculate points. Taking the 2005 IAAF Golden League as an example, the 400-meter sprint was listed as a competition event in Zurich, but not in Berlin.

Under this kind of event setting, athletes cannot appear in two events at the same time. Also taking the 2005 IAAF Golden League as an example, unless you are a high jump athlete, you can't participate in the javelin, it's impossible to participate in the 5,000-meter run, even if you want to participate, you can't meet the registration requirements. To be able to cross two different events you have to also be in the top 20 in the world.

Of course, things are not absolute. There are still two cross-race events in the track and field events that can be communicated, that is, a 100-meter sprint and a long jump. The 100-meter sprint level of long jumpers is not bad. Likewise, a 100-meter sprinter's long jump level is certainly very good. In the normal 4x100m relay race, if one of the players is injured and needs to find a substitute, the first thing that comes to mind is not the 110m hurdle athlete, but the long jumper.

Many athletes in history are proficient in the 100-meter sprint and long jump at the same time. For example, the legendary American flying man Carl Lewis has once set records in the 100-meter sprint, 200-meter sprint, and long jump events. Another example is the American female flying man Marion Jones. Both athletes are proficient in the sprint and long jump. However, after entering the 21st century, no athlete in the world has achieved high achievements in both long jump and sprint events.

A 100-meter sprint is a permanent event of the Golden League, so the 200-meter sprint event would not be seen in the Golden League game, and there will be no situation where the 100-meter sprinter can also participate in the 200-meter sprint. This rule is up to the Diamond League, and can only be changed after replacing the Golden League.

In the 2006 IAAF Golden League, the 400-meter sprint replaced the 110-meter hurdle. According to the international common track and field perception, the 100-meter sprint and the 400-meter sprint are completely different projects, although both of these events are in the sprint category, the span is too large, athletes can't master these two events at the same time. But what the IAAF did not expect was that Zhang Guan would appear in this world. He is not only the ruler of the 100-meter sprint but also able to run 400 meters in less than 45 seconds.

After a moment of silence, Dole asked, "Chairman, if Zhang Guan signs up for the 400-meter sprint race, what should we do?"

"According to the registration rules!" Diaz thought about it, and then said, "Zhang Guan is indeed dominant in the 100-meter sprint event, but in the 400-meter event, Jeremy Varina is the world's strongest athlete, I think Zhang Guan will give up the idea of ​​participating in the 400-meter sprint race if he loses in the previous few races! "

...

After the end of the World Indoor Athletics Championships, Zhang Guan returned to the country with the national team.

It takes almost 11 hours to fly from Moscow to Beijing. This is a very long journey for everyone, and sleeping is the best way to cope with the long journey.

On the plane, the other athletes were already asleep, but Zhang Guan stared, silently thinking about his thoughts.

"I have no problem with the 100-meter project. At least before Bolt appears, I will be the strongest in the world. On the 200-meter project, Crawford of the United States is not my opponent. I need to surpass Bolt before I can be considered the strongest in the world. Michael Johnson's world record of 19.32 seconds seems quite difficult. If I fill up the status, maybe I can sprint another world record. As for 400 meters... "

Zhang Guan remembered the limitation of the "incomplete sprint activation" skill used twice between the interval of more than 30 seconds, and suddenly felt a little depressed, because of this limitation, he could not withdraw this skill in the middle of 400 meters.

"If I am full, it is possible to run into 40 seconds in 400 meters, which seems to be a little insufficient. I cannot change the running method in 400 meters, so I am currently on the 400 meters project and I want to finish it in the shortest amount of time. It may not be possible to improve the performance by a large margin. Perhaps in another two years, the body will be stronger and the stamina will be better, which can impact the world record."

"As I see it now, I'm probably like this in these three projects. Do I want to start a new project? Anyway, there are still a lot of skill points, and it is still sufficient to learn a new track and field project." Zhang Guan thought silently and began to browse the skills in the system.

"Skill jump? Skill sprint jump? By the way, long jump! The long-jump is very suitable for me. For a long jump alone, it should be enough to learn these two skills! These two skills are only six points in total." An involuntary expression appeared on his face.

"If you don't sleep, what are you laughing at?" Liu Feiren's voice sounded beside him.

"Not asleep yet?" Zhang Guan asked subconsciously.

"No, I did not participate in the competition this time in Moscow. After being a cheerleader for three days, I am not tired at all and can't sleep at all." Liu Feiren then asked, "What are you thinking about again?"

"Will you try long-jump?" Zhang Guan asked.

"Long jump? Haha, you asked the right person!" Liu Feiren raised his head confidently, and then said, "To say long jump, I am an expert on this plane!"

Zhang Guan smiled, "Don't blow it first, there are two national triple jump champions on this plane!"

Zhang Guan said that the two national champions of triple jump were also the athletes who participated in the track and field indoor competition with the team, but they were all eliminated in the qualifiers.

Liu Feiren was still very bullish and said, "That's because I didn't continue to practice long jump. If I continue to practice the long jump, it will be better than them!"

"Continue to practice long jump? Have you practiced long jump before? This is the first time I heard that you practiced in something besides the 110 hurdles?" Zhang Guan asked curiously.

Liu Feiren replied, "I started to practice sports when I was seven years old. When I was ten years old, I entered a sports school. My main event was the long jump. When I was 13 years old, I started to practice hurdles. When I was young, I have been in touch with various events in track and field, not only hurdles, but also sprint, long jump, and high jump. By the way, when I was fifteen, I also won the all-round runner-up in the national youth track and field competition!"

Zhang Guan nodded because he didn't know. He hadn't been to a sports school and didn't know what it was like to study in it. But he still asked, "How do you think I should practice the long jump?"

"You want to practice long jump?" Liu Feiren was surprised first and then thought about it very seriously before he said, "Long jump is the same as 100 meters. It looks very explosive. You run so fast at 100 meters. The explosive force must be very strong. If you are going to try a long jump, as long as your skills are qualified, you may be able to jump to the 8-meter mark."

"Is the technique of long jump difficult?" Zhang Guan then asked.

"It's just a long jump. The technical difficulty is okay! I think it's much simpler than hurdles. If you have a triple jump, it may require you to have better techniques." Liu Feiren said of this, he suddenly remembered Zhang Guan practicing corners, it was so exhausting when he was watching him run, he couldn't help but add, "It's quite difficult, you may have to study for a long time!"

Zhang Guan suddenly became speechless. He knew that his learning ability in track and field events was indeed very general, far worse than that of a talented athlete like Liu Feiren.

"You don't have to hit me like that! I'm still a 100-meter world record holder. As you said, the explosive power is strong enough, even if it is average, I should jump farther than others!" Zhang Guan said.

Liu Feiren ignored Zhang Guan's rebuttal, but then introduced, "Long jump can be divided into four movements, running, taking off, flying and landing. And each process has corresponding skills to master. So if you want to jump far away, not only the body but also must have the perfect use of techniques."

"Of course in running, the higher the speed, the better. You shouldn't need to practice too much. No one in the world can run faster than you. The take-off is the key, even if you have good physical fitness and enough explosive power, you have to practice the techniques carefully. There is no shortcut to this. The main reason for flying is to control the balance of the body and adjust the landing. This requires not only techniques but also experience; as for landing, basically, you just do some essential things."

After listening to Liu Feiren's introduction, Zhang Guan nodded silently, and then asked, "What about the triple jump?"

"You can just think of the triple jump as an enhanced version of the long jump." Liu Feiren answered very concisely, then he thought about it and then said, "Triple jump has two more actions than long jump. It's almost the same. So some triple jumpers also have good results in long jump events."

Zhang Guan remembered the Russian long-jump queen Lebedva who competed with him for the million-dollar gold medal in the Golden League last year. She is an athlete who is good at both long and triple jump.

"Coach Yu is a sprint coach. Jumping should not be his strength. If I want to ask a coach for advice, who would be more appropriate?" Zhang Guan then asked.

Liu Feiren said a name that Zhang Guan did not expect at all, "Director Ma! The most powerful long jump coach in the national team is of course Director Ma!"
