After the Spring Festival, Zhang Guan immediately devoted himself to track and field training. Although he has been away from track and field for more than a year, Zhang Guan has been engaged in sports this year, so his competitive status has not declined much. Once he puts into systematic formal training, Zhang Guan can quickly return to his normal state. Peak state.
On the training ground, Director Yu pressed the pause button on the stopwatch, and then immediately looked at the numbers on the stopwatch.
"9.70 seconds by hand! If you include the 0.24 second error in manual timing, the speed of electronic timing 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 sigh of relief.
"What I'm most worried about is that Zhang Guan has not participated in track and field competitions this year, nor has he practiced track and field seriously. His competitive state will seriously decline, and he can't even run 100 meters for 10 seconds. Now It seems that Zhang Guan's competitive performance is still good. He only needs to carry out some recovery training and then find 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 Guanye 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!"
"9.70 seconds on my hand, not bad." Director Yu showed the number on the stopwatch to Zhang Guan, and then continued: "Let's go and test the 200-meter run again."
After that, Zhang Guan successively conducted the 200-meter sprint, 400-meter sprint, 800-meter middle run and 1500-meter middle run tests. The test results showed that Zhang Guan’s competitive status in track and field events has not declined. Basically, it is the same as at the end of 2006. time is flat.
"Boy, you are in good condition! I originally thought that you would not be able to play in the game in your current state, and I even formulated a high-intensity training plan for you, but it seems a bit redundant." Director Yu took the photo He patted Zhang Guan on the shoulder, then pointed in the direction of the sand pool, and then said: "Go, Coach Li is 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. If you get back into shape again, you will have no problem winning the gold medal in the Olympics!" Coach Li said with joy.
"Coach, don't worry, there will definitely be no problem with the gold medal. Although I have not 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, I can't learn the triple jump." Question!"
"Triple jump?" Coach Li hesitated for a few seconds and asked softly: "Do you really want to learn triple jump?"
Zhang Guan nodded solemnly: "I have asked Director Ma to register for me. As long as I get an A-standard result for the National Track and Field Championships in May, I can compete in the Olympics."
"Participating in the Olympics? Do you still want to win a triple jump medal?" Coach Li asked uncertainly.
Zhang Guan shook his head: "It's not a medal, it's a gold medal! Since we are participating in a competition, there is no point in not winning the 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 do it!" Coach Li said.
The triple jump is different from different long jumps. The first jump of the triple jump is a one-legged jump, landing with the jumping leg; the second jump is a step jump, landing with the swinging leg; the third jump is a jump, landing with both feet on the sand. pit. Simply put, it can be regarded as the ordinary long jump plus one-legged hop and step jump.
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 take-off. However, a good run-up is only the first step for the triple jump. The quality of completing an action, the ability to maintain body balance, and the proportion of three jumps will also affect the final result.
For Zhang Guan, he is already a world champion in the long jump and has learned the skill of stepping. Therefore, there are no difficulties that cannot be mastered in the technical movements of the triple jump. Therefore, what Zhang Guan needs to learn most are some details. .
"The approach of triple jump is the same as that of ordinary long jump. The faster, the better. The faster the speed, the more kinetic energy can be obtained. However, the horizontal speed obtained in the approach continues to decrease during the three jumps, so how to reduce The loss of horizontal speed while gaining reasonable vertical speed is the main problem to be solved in triple jump technology."
After Coach Li said this, he paused for a moment to let Zhang Guan digest what he just said, and then said hurriedly: "The total speed loss rate of the world's best triple jumpers can be maintained at 4%. Below ten, this also gives them an advantage in the last two jumps, especially the last jump. The speed loss rate of our country's triple jumpers exceeds this number, which is also the difference between us and the world's top triple jumpers. gap."
"Regarding the ratio of three jumps in the triple jump, there has been a saying a few times about the optimal ratio of three jumps. However, in fact, we cannot arbitrarily stipulate that a certain jumping rhythm is the most appropriate, because of the physical condition and quality level of the athletes. , technical characteristics, psychological state, etc. 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 the triple jump well, you must spend more time In this regard, you must practice your own jumping rhythm as early as possible." Coach Li continued: "In general, the triple jump is to transform raw materials composed of speed, strength, coordination, flexibility and other qualities into A product system composed of three distances. Can you understand that?"
"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 very accurate number to base on, but what is certain at present is that the farther an athlete jumps, the greater the proportion of his third jump. This is the level I just mentioned. The problem of speed loss. The fact that they can jump far means that their horizontal speed loss will be smaller. So, you should focus on practice!" Coach Li said.
