The 400-meter sprint is the most difficult of all sprint events. It has very high requirements for athletes' physiology, special skills, physical fitness, physical strength distribution, and other aspects.
First of all, in terms of physiology, due to the long distance of the 400-meter sprint, anaerobic accounts for a large proportion and aerobic accounts for a small proportion during the entire exercise, so this is a mixed oxygen sprint event. During the exercise, especially in the second half of 400 meters, the high-speed exercise caused oxygen consumption in the body, and the body will be in a state of hypoxia. At this time, the oxygen absorption is lower than the demand for adenosine triphosphate, so it is necessary to the glycogen in the body to break down the lactic acid to provide new energy. This process is a test for athletes, so on the training ground often see athletes with 400 meters will cover their stomachs and want to vomit, which is the normal reaction of the body in an anaerobic state.
In terms of special technology, 400 meters and 200 meters are technically common to a certain extent, but 400 meters has a curve and a straight, which is destined to be different in technical details. At the same time, due to the long distance, the adjustment of physical strength and rhythm has become the key. Athletes can't rush too hard as soon as they come up, and it is impossible to exert no force at all. The physical strength is squeezed cleanly, so athletes should adjust the scene according to the actual physical conditions at the time of the game, which also puts forward new requirements for athletes.
In the system, Zhang Guan found a skill. This skill is called "Incomplete Sprint Activation". The skill description of the ordinary level is "Activate this skill in the state of sprint or curve sprint, you will get 75% of the original effect of the sprint or curve sprint, the physical consumption is reduced to 60%, and the effect disappears after the skill is turned off"; the effect of the expert level increased by 5%, consumption reduced by 5%; Master level has also increased by 5% at the expert level, consumption has been reduced by 5%, and reached the original effect of 85% sprint or corner sprint, and physical consumption reduced to 50 %".
There is no limit to the duration of this skill. Canceling the skill directly can eliminate the effect, but there is a prerequisite for use, that is, the interval between two uses should be greater than 30 seconds.
For the 400-meter sprint, this is a magic skill. The 400-meter sprint is the most difficult to control the speed and rhythm and save physical strength, but this "incomplete sprint activation" skill can do just that. Therefore, Zhang Guan did not hesitate to spend three skill points to upgrade this skill to the master level.
Zhang Guan did not tell Yu Gui that he wanted to practice 400 meters. He knew that if he told Yu Gui, with Yu Gui's temper, he would definitely scold him, saying that he would want to learn to run without even learning how to walk first, but Zhang Guan also has other methods.
At dinner, Zhang Guan sat in front of two athletes specializing in the 400-meter event. At first, he pretended to be a chat. Later, Zhang Guan was involved in the 400-meter event. Speaking of their specialties, these two athletes immediately showed a look of knowing everything.
"The start of the 400-meter dash is not as important as the 100-meter or 200-meter. The 100-meter start is a matter of seconds, and the 400-meter start is more important to make the subsequent acceleration smoother. The first one in the 400-meter run a hundred meters is a curve. At this stage, we must first accelerate. Generally, only 70% or 80% of the force is used. After the speed is quickly increased, it is immediately turned to a uniform curve. The entire curve must maintain a certain rhythm. The second 100m is a straight line there is only a straight line of 80 meters. This stage is mainly a high-speed running at a constant speed. The key point is to control the rhythm. Do not try your best, but not too slow. Try to put yourself in a more comfortable rhythm. The third 100m is the most difficult in the 400m run, mainly because the body's function has begun to decline, and this stage also needs to adjust the rhythm of the movement, as far as possible to adjust the physical condition to the best state to cope with the last 100-meter sprint. There was nothing to say about the last 100-meter sprint. Run as fast as you can!" Said a 400-meter athlete.
"Sounds so complicated!" Zhang Guan said very instructively, "Then how to control the breathing, you can reach the end in one breath when you run 100 meters, how do you breathe for the 400 meters?"
Another person said, "Two steps, one breath, two steps, one breath, or three steps, one breath, three steps, one breath. The methods adopted by different athletes are all different, and each person's physique is different, so it is not easy to say which method is better. You can only choose a method that is more suitable for you. But whether you choose two-step breathing or three-step breathing, you must increase the depth of breathing as much as possible and increase the oxygen content in the body."
"Is there anything else that needs attention?" Zhang Guan then asked.
"That would be more. For example, warming up before running is very important. If you do not do well at 400 meters, it is easy to get injured. I am not talking about trauma on the limbs, but internal injuries to internal organs. It will be more difficult to recover; That is, the pace should be as large as possible during the first half of the run, which can reduce the frequency of some steps, reduce physical exertion, and ensure more speed reserve; also, enter the straight from the first corner and enter the second from the straight In a corner, the rhythm and pace need to be adjusted quickly, otherwise, it will affect the speed; in the second corner... "
The other side said, Zhang Guan nodded while silently remembering it in his heart, but this way of talking on paper made Zhang Guan tickle his heart, he could not wait to get a personal experience on the sports ground.
...
The night is getting dark and the temperature is very suitable, but there is a touch of moisture in the air. The dense branches and leaves hanging on the trees on the side of the roadblock some of the street lights. The shapes, the breezes from time to time, these shapes start to change like little monsters.
Yu Gui directed a sulky walk on the sidewalk. His family is in Beijing, so the time after work every day is a special torment for him, he will think of his family. So occasionally he would call some colleagues to go to a nearby tavern, order a few small dishes, and drink a bottle of wine to relieve the loneliness in his heart. However, those colleagues live in the city, so after the party is over, everyone will go home, and Yu Gui returns to the dormitory of the training base alone.
Seeing that he was about to walk to the entrance of the training base, Yu Gui felt a little irritable. There was only one person in the dormitory. When he went back, he could only face the TV, which made him very bored.
Suddenly, he saw that there was still a trace of lights on the training ground that did not go out. He walked subconsciously, and sure enough, he saw someone still training.
"It's so late, there are people training, who is it!" Yu Gui slowly approached, but found a familiar figure, it is Zhang Guan! Zhang Guan didn't find Yu Gui in the dark.
"It's Zhang Guan!" Yu Guidian was surprised, and then a smile of relief appeared on his face. When he saw that Zhang Guan was still training in the middle of the night, the depressing feeling of loneliness in his heart disappeared instantly. At this moment, he feels that the sacrifices he made before are worthwhile.
"Okay, it's really good! This child has finally grown up! Knowing that his skills still need to be improved, so I will practice in the middle of the night. Just work hard, although this child's ability to learn special skills is indeed worse. But the physical talent is very amazing, and now knows hard work, but the future is limitless!" Yu Gui praised while continuing to hide in the dark, observe Zhang Guan training.
Then, he saw Zhang Guan ran into the straight from the curve, and then did not stop at the end of the straight, but then ran into the next curve.
"How did he run over!" Yu Gui almost shouted, the 200-meter end was at the end of the straight, so Yu Gui thought that Zhang Guan should stop after crossing the straight, but did not expect Zhang Guan to continue to run forward.
"What is he doing?" Coach Yu felt a little inexplicable, and then he saw Zhang Guan ran across the corner again, entered the straight again, and then started sprinting with great speed.
"Why do I feel like he is running the 400 meters? No, this is running the 400 meters!" Even if he was drunk, Yu Gui was still the best sprint coach in China. He made an accurate judgment in an instant. Zhang Guan was running 400 meters.
"Is this what you eat and run! You have to run 400 meters before you even run 200 meters! You want to learn to run without learning to walk! 400 meters is the hardest sprint. Do you think you run like a hundred meters? Headlessly rush forward!" Coach Yu felt a little angry, he was ready to step forward and give Zhang Guan a good lesson.
But then he stopped again, he saw Zhang Guan seemed to be thinking, and then began to warm up again. Since the coach didn't step forward, he decided to observe first.
After taking a break for more than ten minutes, Zhang Guan stood on the starting line again, and it was the starting line for the 400-meter sprint. This time Yu Gui finally determined that Zhang Guan was running 400 meters.
Yu Gui was ready to step forward again, and Zhang Guan had already started moving.
"Huh? At this speed, the rhythm seems to be quite good!" Yu Gui stopped again and continued to observe, he saw Zhang Guan entered the straight from the curve, and then entered the curve again.
"It's bad, it's really bad! It's not like running in a straight corner, ouch, running in a straight corner is even worse!" Yu Gui said a few words but then realized that Zhang Guan's sense of rhythm was very good, especially the first half of the speed distribution looks very good.
"The distribution of speed is very good. The degree of exertion in the first half is just right. No, it can be said to be perfect! Many old athletes can not achieve this level. How did he do it?" Yu Gui knows that a good speed distribution means that more physical energy can be saved for the final sprint. He can't help but look forward to Zhang Guan's final sprint because the straight sprint is Zhang Guan's strongest point.
Sure enough, Zhang Guan had already started accelerating before entering the final straight line. When he rushed into the final straight line, his speed had already increased to an extremely high level.
At this time, Zhang Guan had turned off the "incomplete sprint activation" skill, so he showed that the actual speed is much faster than other athletes at this stage.
"What's the situation! Is he running 400 meters or 200 meters? How did it end up so fast!" Yu Gui blinked, convinced that there was nothing wrong, and then sat on the ground almost scared.
"It's impossible! No one can still sprint with so much energy after running 300 meters! Zhang Guan's speed is now about the same as the sprint speed of some provincial teams' 200-meter athletes. Why is this? How did he do it? Is he still human? Can he make such a speed, indicating that his physical strength is still abundant, how is this possible? Is it possible that the previous consumption is less? But in front, he is not too slow! Is it because the speed is well allocated? The reason, so there will be more physical strength to make the final sprint? "Yu Gui discover that Zhang Guan has done another thing that makes him unable to think.
"In the 400-meter sprint, the distribution of speed and physical strength is the most difficult. Zhang Guan seems to be almost perfect at this point; as for other techniques, it is still too bad! Especially the adjustment between the curve and till this is the most basic skill!" Yu Gui suddenly felt a little depressed, special skills that others easily learned, but Zhang Guan mastered slowly, the speed and physical power distribution that others were struggling to master, but for Zhang Guan, it was a breeze.
"Isn't it talents?" Yu Gui muttered to himself.
At this time, Zhang Guan seemed to be ready to start again.
Yu Gui remembered the terrible technique when Zhang Guan turned into a straight corner and finally couldn't help it. He came out of the darkness and shouted, "Stop, stop, that not how you run into the straight!"
