After resting for a while in the rest area of Yangxin Middle School, Su Zu and Zhang Jiehua, led by another teacher, began to prepare for the 200-meter preliminaries again.

Ao Dingping did not follow to the 200 meters, but first went to the high jump area of the field competition, negotiated with the referee to say hello, gave up the previous test jump first, and waited for the 200 meters preliminaries to end directly over.

"Zhang Jiehua, I found that your results in today's competition are faster than when you were in school." Su Zu and Zhang Jiehua were walking on the playground and asked casually.

"No matter how fast it is, it's not as fast as you." Zhang Jiehua pursed his lips, and his tone was a little unhappy.

"Aren't you going to be doing running lately?"

"No matter how much I practice, I don't practice as much as you, I just go to my aunt's house for dinner after school in the afternoon."

Su Zu chuckled, sure enough, in his previous life, Zhang Jiehua ran a 100-meter and 200-meter sprint, and almost no one in Yangxin Middle School could compare, so he never took it seriously. This time, I was there, but I was stimulated and practiced silently.

Although I don't know where the other party is practicing, it is a fact that the results have improved.

He has always felt that Zhang Jiehua's talent is good, except for physical education class, he has almost never seen him train and run, and he is directly pulled to the track, which is the first in the 100-meter grade of Yangxin Middle School.

No matter how unqualified Yangxin Middle School is, it is also a township of 60,000 or 70,000 people, and there are more than 200 boys in the first class of junior high school students. At least one in a hundred levels, in terms of academic performance, at least you can go to the level of a prestigious university.

By analogy across the country, there are actually many excellent seedlings, but at the time when they are the most talented, many people do not have the opportunity to discover them, and they don't know it. Gradually, as the years grew, it became clear to everyone.

Of course, this is also a national condition, subject to the quality of the race and the level of training, maybe there may not be many sprinters at the top level, but in the second and third gears, this kind of sprinters should have a huge base.

An excellent selection mechanism will definitely be able to select a lot of good seeds, in the future, although the domestic running and jumping in many events still do not reach the highest level of foreign countries, but there have been more and more seeds to stand out, the training method is more and more scientific, and the selection mechanism is more and more perfect.

The fundamental reason is that the economic conditions are better, and the diet training has been improved.

For example, in a project like 4X100, which pays attention to individual strength and relies on team cooperation, China and Japan have reached the level of the world's first echelon in later generations. The rise of various other projects is too numerous to mention

The circular runway of Wuxing No. 1 Middle School is 300 meters, and it is also paved with cinders, and Su Zu remembers that it should be funded in two years before Wuxing No. 1 Middle School will be replaced with a plastic runway. This was the first middle school with a plastic runway in Wuxing County at that time.

Soon after Suzu waited in the 200m preliminaries, the group stage of the preliminaries had already begun.

The number of participants from each middle school in the preliminaries was 28, divided into five groups, this time Su Zu was in the second group, and Zhang Jiehua was in the fourth group.

Before the starting line, this time Su Zu received much more attention than before, after all, he had just finished running a hundred meters and broke the record of the county middle school sports meeting, everyone could see that his strength was beyond a cut, and he would naturally receive some people's attention.

Next to the runway, at this time, there were a few physical education teachers from Wuxing No. 1 Middle School standing next to them and touching their chins to observe, considering whether they could make a special case for enrollment if the grades were not too bad during the high school entrance examination, after all, in this year, in the poor place of Wuxing County, good seedlings are indeed too rare. It's just that there are still a lot of rules and regulations to go through, and at this stage, there is no enrollment of sports specialties in Wuxing No. 1 Middle School in the middle school entrance examination.

Everyone is a physical education teacher, at least a physical education major or a sports system from a normal college, and they understand what it is to be able to run 12 seconds in a township junior high school student. Look at the starting posture, running posture, you can see that you have not undergone professional training, if only there was a school track and field team, you can directly recruit. It's a pity that Wuxing No. 1 Middle School has not yet opened, and it is only available in Jianping City or some big city key middle schools.

Before the starting line of the 200-meter preliminaries, after the starting gun sounded, the competitors of the group race shot out again.

This time, Su Zu did not run with all his strength like 100 meters, but kept controlling the rhythm of running, adapting to the effect of the combination of sudden increase in strength and agility.

This kind of attribute power that grows out of thin air, if it does not go through a certain period of adaptation, the body will become unfamiliar, and it is easy to lose balance in the processing of details.

But Rao is like this, Su Zu still easily ran the first place in the group, throwing off the second place five or six meters away, and the final result was 25.22 seconds, which was about the same as his result in the final of the school games.

Generally speaking, high-level professional athletes, after long-term training, have speed continuity and relatively strong willpower, speed endurance and speed durability, and the body's lactic acid tolerance is high.

But ordinary people or junior high school students, have not been trained, so their training continuity and speed endurance and so on do not have a great strength base, the first 50 meters are fast, the better 100 meters can also maintain the speed, but the second half of the 200 meters will have a big drop in the basic speed.

This is also the "Athletics Athlete Technical Grade Standard", the 100-meter note of Level 3 athletes is 12.40 seconds, and the 200-meter record is 25.50 seconds.

Among many professional athletes, there are many people who run 200 meters and 100 meters, and most of them are more difficult to achieve results when they change from 100 meters to 200 meters, except for some talents.

Taking the IAAF official website as an example, listing the top 100 best results in the 100m and 200m in history, the number of times and the number of people running 10 seconds in the 100 meters is far more than running in the 200 meters in 20 seconds.

After running the 200-meter preliminaries, Su Zu and other referees wrote down the numbers on their backs, and they didn't bother to look at the results of other groups of players, so they hurriedly ran to the high jump area of the field competition.

The high jump competition has just begun, and the first round of the 1.3-meter test jump has passed, because Ao Dingping has communicated in advance, so the first round of the test jump Su Zu did not participate, and directly reported that it started from the 1.45-meter test jump.

There are not many boys in the junior high school group who participate in the high jump competition, but because it is a county games, the quality is good, and the ones who come are basically the top one or two in each middle school in their age.

From the first round of test jumps, it quickly reached the height of 1.45 meters.

Su Zu just finished participating in the 200-meter preliminaries, and his breath was still a little uneven, but this height was not difficult, and he passed the first attempt to jump directly by leaps and bounds, and then was pulled aside by Ao Dingping to sit and rest.

Although it seems that the 100-meter final and the 200-meter preliminaries are not very large, this is a sprint, which is an anaerobic way of exercising, and the maximum intensity of extreme sports in a short period of time produces a large amount of lactic acid accumulation, which can easily cause muscle soreness, which affects the results of other subsequent competitions.

The high jump bar continues to climb with round after round of trial jumps. By the time the height reached 1.6 meters, most of the contestants had already been eliminated, and there were only three or five people left. At this age of the junior high school group, the height of 1.65 meters is already very challenging.

Su Zu only jumped 1.65 meters in the Yangxin Middle School Games, of course, it was a leapfrog type, and this time the county games will obviously have more players who will jump on their backs, and the movements are relatively standard, more or less it can be seen that there has been a special person to point out.

"It seems that you still have to use the back Yue style."

Su Zu sighed in his heart, whether the back crossing style is definitely higher than the leapfrog jump, this Su Zu can't say for sure, but in his use, the back crossing style must have an advantage over the leapfrog style.

Of course, in a video on the Internet in later generations, in the high school high jump competition in Kenya, Africa, those talented and terrifying high school students can reach a height of 1.92 meters in the mud barefoot.

And the king of the 1.94-meter high jump, Javier Sotomayor, was able to jump more than 50 centimeters above his height, which is a miracle in the history of mankind. Decades have passed, and the world record he has set has been thrown high and can only be broken by future generations.

Moreover, high jump pays attention to physical fitness, flexibility, bounce, explosiveness and body coordination, as well as a lot of understanding. Some people have never jumped high, and suddenly see someone jump once, leapfrogging or back-to-back jumping, and they can learn it as soon as they learn it, while some people can't coordinate their bodies well anyway.

Su Zu has never been taught by anyone in the back-to-back high jump, in the last time and space of the county games, imitated others to jump once, and successfully jumped to 1.65 meters, winning the second place. Later, I went to high school and college, and I also studied some one after another, but after college, due to my height and talent, I couldn't compare with others among the piles of sports students, and then I simply gave up.

And in this life, because of the system, the agility quality and strength quality have been improved to varying degrees, and he has experienced it in sprinting, and he also wants to try high jump.
