Chapter 392 Returning to track and field training (eight more)

After the Spring Festival, Zhang Guan immediately devoted himself to track and field training. Although it has been more than a year away from track and field, Zhang Guan has been engaged in sports for this year, so his competitive state has not declined too much. Once he is put into systematic and regular training, Zhang Guan will soon recover Peak condition.

On the training ground, Director Yu pressed the pause button of the stopwatch, and then immediately looked at the numbers on the stopwatch.

"The hand clock is 9.70 seconds! If the 0.24-second error of the manual clock is counted, the speed of the electronic clock is 9.94 seconds, which is still the world's top speed. And Zhang Guan obviously hasn't tried his best! It seems that he has not participated in formal track and field training for more than a year. Zhang Guan's condition is still very good." Director Yu let out a long breath.

"What worries me the most is that Zhang Guan hasn't participated in track and field competitions this year, nor has he conducted serious track and field training. His competitive state will decline seriously, and he can't even run 100 meters in 10 seconds. Now It seems that Zhang Guan's competitive posting is still good. He just needs to do some recovery training, and then find out the state of the game through a few warm-up matches. When it comes to the Olympics, although he may not be able to break the world record, he will win the gold medal There should be no problem." Director Yu thought silently.

Zhang Guan also came over from behind the finish line and asked, "How's the result? It's okay! If you're not satisfied, I'll run again and run faster!"

"It's 9.70 seconds by hand, not bad." Director Yu showed Zhang Guan the number on the stopwatch, and then said, "Let's go, let's test the 200-meter run again."

Afterwards, Zhang Guan conducted the tests of 200-meter sprint, 400-meter sprint, 800-meter middle-distance race and 1500-meter middle-distance race. when flat.

"Boy, you are in good shape! I thought you would not be able to play in your current state, and I have specially formulated a set of high-intensity training plans for you, but it seems a bit redundant." Director Yu patted He patted Zhang Guan on the shoulder, then pointed to the direction of the sand pool, and said, "Go, Coach Li is still waiting to test your long jump from over there!"

...

A few minutes later, Zhang Guan jumped 8.32 meters in the long jump event.

"Okay, I haven't regressed at all. You can get back to your status. It's no problem to win the gold medal in the Olympics!" Coach Li said with a smile on his face.

"Coach don't worry, the gold medal is definitely not a problem. Although I haven't participated in track and field competitions for more than a year, I have never relaxed physically." Zhang Guan continued: "Coach Li, in my current state, is it okay to learn the triple jump? Question!"

"Triple jump?" Coach Li hesitated for a few seconds, then asked softly, "Do you really want to learn triple jump?"

Zhang Guan nodded solemnly: "I have asked Director Ma to help me sign up. In the National Athletics Championships in May, as long as I jump out of an A mark, I will still go to the Olympics."

"Participate in the Olympics? Do you still want to win a medal in the triple jump?" Coach Li asked uncertainly.

Zhang Guan shook his head: "It's not a medal, it's a gold medal! Since it's a competition, it's meaningless not to win a gold medal."

"Olympic triple jump gold medal?" Coach Li's tone was a little surprised, and when he saw Zhang Guan's serious expression, he immediately felt the persistence and desire for the gold medal in Zhang Guan's heart.

"Okay, if you want to practice, I'll hand it in!" Coach Li said.

The triple jump is different from different long jumps. The first jump of the triple jump is a hop, which lands with the take-off leg; the second jump is a stride jump, which lands with the swinging leg; pit. Simply put, it can be seen as an ordinary long jump with hops and strides added.

The run-up is also very important for the triple jump. The final result also depends on the horizontal speed obtained during the run-up and the vertical speed generated by the jump. However, a good run-up is only the first step for the triple jump. The quality of an action completed, the ability to maintain body balance, and the proportion of the three jumps will also affect the final score.

For Zhang Guan, he is already the world champion of long jump, and he has also learned the skill of stepping, so there is no difficulty in the technical movements of the triple jump, so what Zhang Guan needs to learn most is some details. .

"The approach run of the triple jump is the same as that of the ordinary long jump. The faster the better. The faster the speed, the more kinetic energy can be obtained. However, the horizontal speed obtained during the run-up is continuously reduced during the triple jump, so how to reduce it? The loss of horizontal speed while obtaining reasonable vertical speed is the main problem to be solved in triple jump technology.”

After Coach Li finished speaking, he paused for a moment to let Zhang Guan digest what he had just said, and then hurriedly said: "The total speed loss rate of the best triple jump players in the world can be maintained at 4%. This also gives them an advantage in the last two jumps, especially the last jump. However, the speed loss rate of our country’s triple jumpers exceeds this figure, which is also the difference between us and the world’s top triple jumpers. gap."

"With regard to the ratio of the three jumps of the triple jump, there has been a saying that there is an optimal ratio of the three jumps several times, but in fact, it is impossible to arbitrarily stipulate that a certain jump rhythm is the most suitable, because the athletes' physical conditions and quality levels , technical characteristics, psychological state and other aspects are very different, so each athlete must go through practice to form a jumping rhythm that is more suitable for his own characteristics. If you want to learn triple jump well, you must spend more time next In this regard, you must practice your own jumping rhythm as soon as possible." Coach Li continued: "In general, the triple jump is to transform the raw materials composed of speed, strength, coordination, flexibility, etc. A product system composed of three distances. So you can understand, right?"

"I understand." Zhang Guan nodded and then asked: "You just mentioned the ratio of three jumps. What is the ratio of three jumps for ordinary athletes?"

"There is really no accurate number to base this on, but what is certain at present is that the farther the athlete jumps, the greater the proportion of his third jump is, which is what I just said The problem of speed loss. They can jump far, which means that the loss of their horizontal speed will be smaller. So, you should focus on practice!" Coach Li said.
