With the retirement of Liu Xiang, the leader of Chinese track and field, Zhu Tianyun has truly taken over the position of Liu Xiang's first brother in track and field, Zhu Tianyun won the silver medal in the 100 meters, which made Huaxia ranked among the fastest flying men in the world, and then won the gold medal in the long jump and 400 meters, and became the man of the year in the Olympic Games with 2 gold and 1 silver score, so Zhu Tianyun's triple jump qualifying round, Huaxia's media broadcast live for the first time. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

Zhu Tianyun and Dong Bin are in Group B of the qualifying round, and another player, Cao Shuo, is in Group A, and the rules of the triple jump are very similar to the rules of the long jump.

The triple jump originated in Scotland and Ireland in the mid-18th century, with the men's triple jump being included in the first Olympic programme in 1896 and the women's triple jump becoming more widespread in the early 80s of the 20th century and being listed as an Olympic event in 1992.

The triple jump is composed of a one-legged jump, a stride jump and a jump, and engaging in the practice of the triple jump has the same exercise value as the long jump.

The original triple jump technique was relatively low-level, and people's understanding of the technical characteristics of the sport was relatively superficial, and the stride jump of the second jump was only used as a transition between the first jump and the third jump. In 1936, a Japanese athlete was the first to jump 16 meters, and his technical characteristics were that he jumped high and far in the first jump, took off vigorously, and moved dexterously. However, the second jump is sluggish, the distance is shorter, and the rhythm of the third jump is uneven. In 1955, a Brazilian athlete jumped a new level of 16.56 meters.

In the mid-fifties, Soviet athletes improved the technique of "one-legged jumping", which was characterized by a high parabola, a late exchange of legs, and a high swing of the leg landing, which allowed a new improvement in performance. At the beginning of the sixties, Polish athletes jumped 17 meters, and their technical characteristics were fast jumps, low parabola in the air, good forward mobility of the body, and long jumps in the third jump. People have deepened their understanding of triple jumps through continuous exercise practice.

The triple jump is a sport in which you make three consecutive jumps in a straight line after a run-up. Since this sport puts a lot of burden on the lower limbs, the requirements for physical fitness are a bit higher than in other sports. It requires the athlete to have a fast run-up speed and good bounce, as well as strong leg strength.

The current world record in the triple jump was set by Great Britain's Joe Edwards in Gothenburg, Sweden, in 1995 with a mark of 18.29m.

Dong Bin is much stronger than Cao Shuo's psychological quality in Zhu Tianyun's opinion, and it may also be due to his age, Dong Bin is 88 years old, and Cao Shuo is 91 years old. On May 17, 2009, at the 11th National Games Track and Field Qualifiers and National Track and Field Men's Championships in Yulin City, Guizhou Province, the little-known Henan Provincial player Cao Shuo won the gold medal in the men's triple jump with a score of 17.13 meters, becoming the first person in history to jump the 17-meter mark at the age of 17. The previous record for the longest triple jump at the age of 17 was Cuba's Yorbi Quesada, who jumped 16.98m in 1991, a full 15 centimetres above the previous record. For the next 18 years, the record remained in the dust. His astonishing jump attracted the attention of the IAAF.

But Cao Shuo can be said to be an emotional player, when his feeling comes to 17.30 meters, he can easily jump out, but when his feeling is gone, sometimes he can jump more than 15 meters, and according to Zhu Tianyun's observation just now, Cao Shuo's pressure is too great, and he may not even qualify.

There are 25 competitors participating in the men's triple jump qualifying competition, which is divided into 2 groups according to the rules, 13 in Group A and 14 in Group B. At the London Olympics, the passing line for the men's triple jump qualification was 17.10m. If the number of qualified players is not enough, the top 12 players with the best results will be selected.

Zhu Tianyun didn't mean to show off, he wanted to skip the qualifying round, save his physical strength to prepare for the 200-meter preliminaries, you must know that in addition to the triple jump qualifying tournament today, the 200-meter preliminaries and the high jump final, Zhu Tianyun's burden is very heavy.

Zhu Tianyun is the second to play, not only Dong Bin, but also other players in Group B, Taylor of the United States, Mali Van Sanz of Baja, Donato of Italy and others all looked at Zhu Tianyun who was preparing for the competition with a solemn face, Zhu Tianyun broke the world record in the long jump and put too much pressure on them, it is foreseeable that Zhu Tianyun's bounce and explosiveness are top-notch, how can they not be nervous.

Zhu Tianyun walked to the starting place, and he must know that the triple jump competition venue is composed of a runway, a starting board, a starting display board, a plasticine display board and a landing area. The running area is 40 to 45 meters, which is about the same distance as the long jump.

Zhu Tianyun took a deep breath, he was not ready to show his best level, the running was just a decent speed, and he didn't come up with too high a speed, but Zhu Tianyun's sense of rhythm was nothing to say, when it came to the pedal, Zhu Tianyun deliberately did not step on the board, and jumped when the distance was 30 centimeters.

"Is Zhu Tianyun's technical move a high jump?" The narrator was taken aback when he saw Zhu Tianyun's jump, Zhu Tianyun can be said to be the second time to show his triple jump, but he didn't expect Zhu Tianyun's technical essentials to be the high jump that is now gradually eliminated.

The triple jump can be divided into two different types of techniques, namely "high jump" and "flat jump", and the proportion of the three jumps of the "high jump" technique is generally 36%-30%-34%, that is, the vertical velocity of the first jump is larger, the center of gravity parabola is higher, and the first jump is better. And the flat jump type technology, the proportion of its three jumps is 34%-30%-36%, that is, medium-small-large, this technique has higher requirements for the starting and forward-looking nature of the one-legged jump, so that the body rises along the long and flat trajectory, so the horizontal speed loses less after the first jump, although the first jump is often not as good as the first jump of the "high jump", but the last two jumps are more stable, especially the third jump is better.

Former Soviet runner Voloshin jumped 17.74m in 1990 and Conley won gold at Barcelona 1992 with 18.17m, and some have compared the two athletes.

Voloshin is a high-jump athlete and Conley is a flat-jump athlete. Although Voloshin's first jump was good, it affected the results of the second and third jumps; Conley's flat jump technique, he can maintain a large horizontal speed until the last jump, although the first jump is far inferior to Voloshin, but the third jump is 7.00 meters, becoming the first athlete in the world to break the 18-meter mark.

Since then, the high jump of the triple jump has been eliminated by the flat jump, but Zhu Tianyun's first step is the technical characteristics of the high jump, because of Zhu Tianyun's bounce power, Zhu Tianyun's high jump, the first step is particularly far.

The next two steps Zhu Tianyun artificially retracted, so Zhu Tianyun only jumped out of 17.16 meters, but Zhu Tianyun's first step to the third step are big-small-medium, which is completely in line with the characteristics of high jump, so many people who know about the triple jump on the Internet feel that they are hanging, and they scold what a garbage coach can educate Zhu Tianyun, a player with such a high talent, like this? Of course, if Coach Lu knew about it, he would definitely vomit blood aggrieved, because this is not Zhu Tianyun's level at all, his complete results are obviously a big-small-big model, and he finally has obvious strength, even if Coach Lu himself sees it, but no one believes him even if he explains it now.

"No, how can Zhu Tianyun's technical characteristics be the characteristics of high jumps? This feature has been discarded for so many years, and flat jumping is the trend of development? "That's probably what everybody thinks.

"Xiao Zhu, who is your coach? How could such outdated technology be used? Dong Bin asked directly, he was also worried about Zhu Tianyun's results, the more top players are, the more obvious it is.

"What, Brother Dong?" Zhu Tianyun didn't know why, although he also contacted the triple jump, but his effort in the long jump was obviously greater than the triple jump, although the coach at the time had said it, but he really didn't care, he felt how suitable for himself how to come.

When Dong Bin explained the flat jump and high jump of the triple jump to Zhu Tianyun, Zhu Tianyun reacted, that's all? Zhu Tianyun felt that his bouncing power and air retention force were obviously more suitable for high jumps, so he was not ready to change, Dong Bin could only give up, he felt that Zhu Tianyun was wasting his talent, but Dong Bin couldn't say anything, because he was an Olympic champion, he was nothing.

Taylor jumped 17.21m on his first jump.

"Zhu, I didn't expect you to be a classical triple jumper, but your jumping style is outdated." Taylor walked over.

"Well, why don't I think?" Zhu Tianyun shook his head.

"You still don't believe it, your grades are not as good as mine, this is the evidence." Taylor didn't hide it at all, and also introduced the shortcomings of the high jump to Zhu Tianyun.

"That's who I am, and I'm not prepared to change it." Zhu Tianyun said stubbornly, because Zhu Tianyun and Taylor both crossed the 17.10-meter score line, so they both gave up other opportunities to try jumping.

None of the players in Group 1 had a score of 17.10m or more, while seven people from Group A advanced to the final based on their results. France's Compaoré topped Group A with a time of 17.06m. In second place in Group A was Italy's Greco with a score of 17.00m. Russia's Adams scored 16.88m. In addition, Clay of the United States finished fourth in Group A with 16.87m, while Oak of Nigeria had 16.83m, Haiti's Lane had 16.81m, and Belarus's Platnitsky had 16.62m. Huaxia player Cao Shuo's score in the first jump was 16.11m, the second jump was 16.26m, and the third jump was 16.27m. Cao Shuo's final score was 16.27m, ranking 11th in Group A and missing the final.

Zhu Tianyun knew that this was not Cao Shuo's real level at all, it could be pressure, or it could be the experience of the competition, anyway, Cao Shuo failed and did not qualify.

Zhu Tianyun's level in Group B is much higher, there are 3 players in Group B who meet the standard, and the American star C-Taylor's score is 17.21 meters, ranking first in the group; Bahamas' L. Saunders finished second overall in the heats with 17.17m. Zhu Tianyun's 17.16m ranked third. Chinese star Dong Bin performed well in the qualifying round, and when there was no result in the first jump foul, Dong Bin jumped 16.94 meters in the second jump, which was enough to ensure that he entered the finals, so Dong Bin gave up the third jump. Dong Bin's score of 16.94 meters ranked fourth in the group.

According to calculations, among all the players in the qualifying round, Zhu Tianyun's results ranked third in the qualifying round, and Dong Bin's results ranked sixth. This was originally a very good result, because there were two Chinese players in the final of the triple jump, but those who watched Zhu Tianyun's competition were full of worries about Zhu Tianyun's triple jump technique.

"The Chinese double advanced to the finals, can the classical jumping method rejuvenate itself? "Many of the media in China have quoted this article, this article in the Black Province Daily, after the test of time, the flat jump of the triple jump is the mainstream, although they did not use a strong questioning tone, but after a lot of comparison of facts, they still raised concerns, but Zhu Tianyun is in the limelight, they did not say that it was Zhu Tianyun's problem, and the spearhead was directed at Zhu Tianyun's coach.
