The 400-meter dash is the most difficult of all sprint events. It places high demands on athletes' physiology, special skills, physical fitness, and physical distribution.
First of all, in terms of physiology, due to the long distance of the 400-meter sprint, anaerobic accounting for a large proportion and aerobic accounting for a small proportion during the entire exercise process, so this is a mixed-oxygen sprint event. During exercise, especially in the second half of 400 meters, the previous high-speed exercise causes 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 must be Glycogen in the body is broken down into lactic acid to provide new energy. This process is actually a test for athletes, so it is often seen on the training field that 400-meter athletes will hold their stomachs and look like they are about to vomit. In fact, this is a normal reaction of the body in an anaerobic state.
In terms of specialized technology, the 400m and 200m are technically common to a certain extent, but the 400m has an extra curve and a straight, which means that the technical details are definitely different. At the same time, due to the relatively long distance, physical distribution and rhythm adjustment have become the key. Athletes cannot rush too hard as soon as they come up, nor can they not use force at all. The best situation is to just finish their 400 meters. Physical strength is squeezed cleanly, so athletes must come to the field to make adjustments based on their actual physical conditions during the competition, which also puts forward new requirements for athletes.
In the system, Zhang Guan found a skill. The name of this skill is "Incomplete Sprint Activation". The skill description of the ordinary level is "When you activate this skill while sprinting or sprinting in a curve, you will get 75% of the original effect of sprinting or sprinting in a curve, and the physical consumption is reduced to 60%. The effect disappears after turning off the skill"; the effect of expert level It has increased by 5%, and the consumption has decreased by 5%; at the master level, the effect has increased by 5%, and the consumption has decreased by 5%, reaching "85% of the original effect of sprinting or curved sprinting, and the physical consumption is reduced to 50 %".
This skill has no duration limit. Simply canceling the skill can eliminate the effect, but there is a prerequisite for its use, that is, the interval between two uses must be greater than 30 seconds.
For the 400-meter sprint, this is definitely a magical skill. Controlling the speed rhythm and conserving physical strength are the biggest difficulties in the 400-meter sprint, and this "incomplete sprint activation" skill can do just that. So Zhang Guan spent three skill points without hesitation to upgrade this skill to master level.
Zhang Guan did not tell Instructor Yu that he wanted to practice 400 meters. He knew that if he told Instructor Yu, with Instructor Yu's temper, he would definitely scold himself and say that he would learn to run before he could even walk. But Zhang Guan also has other methods.
At dinner, Zhang Guan sat in front of two athletes who specialized in the 400-meter event. At first, they pretended to chat, but then the topic turned to the 400-meter event. When it came to their own special events, the two athletes immediately showed that they knew everything and talked about it.
"The start of the 400-meter sprint is not as important as the 100-meter or 200-meter sprint. The start of the 100-meter sprint is every second, but the start of the 400-meter sprint is more important to make the subsequent acceleration smoother. The first one in the 400-meter sprint The 100 meters is a curve. At this stage, you must first accelerate. Generally, you only use 70% to 80% of the force. After quickly increasing the speed, you immediately switch to running at a constant speed in the curve. The entire curve must maintain a certain rhythm. The second 100 meters is a straight road. It is said to be a straight line, but in fact it is only an 80-meter straight line. This stage is mainly about high-speed running at a constant speed. The key point is to control the rhythm. Don't try your best, but don't go too slow, and try to keep yourself in a more comfortable rhythm. The third 100 meters is the most difficult of the 400-meter run, mainly because the body's functions have begun to decline, and at this stage it is necessary to adjust the rhythm of exercise and adjust the physical condition to the best possible state to cope with the challenge. The sprint of the last 100 meters. As for the sprint of the last 100 meters, there is nothing to say. Run with all your strength and run as fast as you can!" said a 400-meter athlete.
"It sounds so complicated!" Zhang Guan said in an instructive manner: "How do you control your breathing? You can reach the finish line in one breath when running 100 meters. How do you breathe for 400 meters?"
Another person said: "Two steps, one exhale, two steps, one inhale, or three steps, one exhale, three steps, one inhale. Different athletes use different methods. Everyone's physique is different, so it's hard to say which method is better." 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's a lot. For example, warm-up before running is very important. If you don't do a good warm-up for 400 meters, you can easily get injured. I'm not talking about trauma to the limbs, but internal injuries to internal organs. Recovery will be more troublesome; and That is, the pace should be as wide as possible in the first half of the run. This can reduce the frequency of some steps, reduce physical exertion, and ensure more speed reserves; in addition, enter the straight from the first corner and enter the second from the straight. During the first corner, the rhythm and pace need to be adjusted quickly, otherwise the speed will be greatly affected; in addition, during the second corner... "
As the other party spoke, Zhang Guan nodded and silently remembered it in his heart. However, this kind of paper talk made Zhang Guan feel itchy. He couldn't wait to go to the sports field to experience it in person.
…
The night is getting darker, 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 roadside partially block the street lights. The dim lights shine on the ground through the gaps in the leaves, forming strange shapes. Shapes, every now and then the breeze blows, and these shapes begin to change like little monsters.
Director Yu walked on the sidewalk with a drunken look on his face. His family are all in Beijing, so every day after get off work is a special kind of torture for him, and he will think of his family. So occasionally he would ask a few colleagues to go to a nearby tavern, order a few side dishes, and drink a bottle of wine to relieve the loneliness in his heart. However, those colleagues all live in this city, so after the party, everyone will go home, and Director Yu can only return to the dormitory of the training base alone.
Seeing that he was about to reach the entrance of the training base, Director Yu felt a little irritable. He was alone in the dormitory. When he went back, he could only watch the TV, which made him feel very bored because of his active nature.
Suddenly, he saw that there seemed to be a light that had not been extinguished on the training ground. He subconsciously walked over and saw someone still training.
"It's so late, there is still someone training, who is it!" Director Yu slowly approached, but found a familiar figure, it was Zhang Guan! However, Zhang Guan did not find Yu Guiding in the dark.
"It's Zhang Guan!" Director Yu was surprised at first, and then a relieved smile appeared on his face. When he saw that Zhang Guan was still practicing in the middle of the night, the depressed loneliness in his heart disappeared instantly. , at this moment he felt that the sacrifices he had made before were worth it.
"Okay, that's great! This kid has finally grown up! He knows that his skills still need to be improved, so he comes to practice more in the middle of the night. It's good if he is willing to work hard, although this kid's learning ability in special skills is indeed a bit poor. , but the physical talent is very amazing, and now that I know how to work hard, the future is limitless!" Director Yu praised, while continuing to hide in the darkness and observe Zhang Guan's training.
Then, he saw Zhang Guan running from the corner into the straight, and then did not stop at the end of the straight, but then ran into the next corner.
"Why did you overrun?" Director Yu almost shouted. The end of the 200 meters was at the end of the straight, so Director Yu thought that Zhang Guan should stop after crossing the straight, but he did not expect that Zhang Guan was still running forward.
"What is he doing?" Director Yu felt a little confused, and then he saw Zhang Guan running through the curve again, entering the straight again, and then started sprinting at an extremely fast speed.
"Why does it feel like running 400 meters? No, this is running 400 meters!" Even though he was drunk, Director Yu was still the best sprint coach in the country. He made accurate judgments in an instant. Zhang Guan was Running 400 meters.
"Is this because of eating and running? I haven't run 200 meters yet, so I run 400 meters! I want to learn to run before I can walk! 400 meters is the most difficult sprint. Do you think it is the same as running 100 meters? Are you rushing forward mindlessly?" Director Yu felt a little angry, and he was ready to step forward and teach Zhang Guan a lesson.
But then he stopped again. He saw Zhang Guan seemed to be thinking, and then started doing warm-up exercises again. Director Yu did not step forward, so he decided to observe first.
After Zhang Guan rested for more than ten minutes, he stood on the starting line again, and it was the starting line of the 400-meter dash. This time, the instructor finally confirmed that Zhang Guan was really running 400 meters.
Director Yu was about to step forward again, but at this time Zhang Guan had already started to move.
"Huh? This speed seems to have good rhythm control!" Director Yu stopped again and continued to observe. He saw Zhang Guan enter the straight from the curve, and then entered the curve from the straight. .
"It's bad, it's really bad! This is not how you run when you go from a curve to a straight. Oops, it's even worse when you go from a straight to a curve!" Director Yu complained a few words, but then he realized that Zhang Guan had a very good sense of rhythm, especially The speed distribution in the first half of the race looks very good.
"The distribution of speed is very good, and the degree of force exerted in the first half is just right. No, it should be said to be perfect! Many old athletes cannot achieve his level. How did he do it?" Director Yu Knowing that good speed distribution means more energy can be saved for the final sprint, he couldn't help but start to look forward to Zhang Guan's final sprint, because straight-line sprinting is Zhang Guan's strongest point.
Sure enough, Zhang Guan had already started accelerating at full speed before he entered the final straight line. When he reached the final straight line, his speed had increased to an extremely high level.
At this time, Zhang Guan had turned off the "incomplete sprint activation" skill, so his actual speed was much faster than other athletes at this stage.
"What happened! Did he run 400 meters or 200 meters? Why was he so fast in the end!" Director Yu blinked, making sure he saw it correctly, and then he almost sat on the ground in fright.
"This is impossible! No one can run 300 meters and still have enough energy to sprint! Zhang Guan's current speed is similar to the sprint speed of some provincial team 200-meter athletes. Why is this? How did he do it? ? Is he still human? Being able to achieve such speed shows that he still has plenty of physical strength. How is this possible? Could it be that the consumption in the front is less? But he is not too slow in the front! Is it because the speed is well distributed? Reason, so he has more physical strength to make the final sprint?" Yu guided him and found that Zhang Guan had done something that he couldn't think about.
"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 the straight line, which is the most difficult. He doesn't know basic skills!" Director Yu suddenly felt a little depressed. Zhang Guan mastered the special skills easily for others; the speed and physical distribution that others struggled to master were easy for Zhang Guan. .
"Could it be another talent?" Director Yu murmured to himself.
At this time, Zhang Guan seemed to be ready to start again.
Director Yu suddenly remembered Zhang Guan's poor technique when turning the curve into the straight. Finally he couldn't bear it anymore. He walked out of the darkness and shouted at the same time: "Stop, stop, stop, this is not how you run on the straight!"
