Running method selection

In the first 100 meters, the athletes ran relatively smoothly. Among the athletes who participated in the 400-meter sprint competition this time, there were no such athletes who were partial to the pre-run method, so everyone's speed was not very fast. In this case, Zhang Guan's speed seems to be a bit faster than others, which is the advantage of absolute speed.

"Zhang Guan seems to be opening very fast!"

"Is this a biased run?"

Those who haven't watched Zhang Guan's game couldn't help but start to guess Zhang Guan's running style.

Varina had watched the video of Zhang Guan's game. He knew that Zhang Guan used this running method. In the first three hundred meters, he ran at rhythm, and he would sprint violently at the end.

"Zhang Guan's rhythm and speed are slightly faster than on the video. If he runs according to the way he usually uses, he will maintain this rhythm until 300 meters, which means that his speed today must be faster than usual. Is it because of the good condition?" Varina remembered that Zhang Guan ran to the 9.70-second mark in the morning, at least to show that Zhang Guan's condition is good today.

"Zhang Guan is faster than usual, and I have to mention the rhythm a little bit." Varina thought of this and began to adjust his rhythm to make it a little faster.

In the middle and long-distance race, the athletes will go to the inner track after crossing the lane. At this time, the speed of the leading athlete will affect other athletes, so there is a rhythm. In the 400-meter race, Although everyone has a fixed runway, there are also rhythm situations. Especially when the outside track athletes run faster, the inside athletes will have a feeling of falling behind and will also increase their speed, so that everyone's speed becomes faster, and the overall rhythm will be brought up.

As Varina's teammate, Harris used the same running method as Varina. He observed that Varina started to speed up, and then began to speed up. At the same time, the speed of the Bahamas star Brown and Canadian star Taylor has also increased a bit. Only the speed of two Jamaican athletes has not changed much.

The running styles of the two Jamaican athletes are somewhat different from those of others. Among them, Blackwood uses a more mid-range running method. His speed in the second and third 100m stages will be very fast. The last sprint will be slower; Simpson uses two straight accelerations. He will slow down in two corners and start sprinting on two straight runs.

Nothing is outstanding in the first 100 meters of the game. Starting, accelerating, adjusting during acceleration, and entering the rhythm of the game as soon as possible are all things that all athletes must do. For the commentary and the audience, all this is quite satisfactory, and there are no commendable highlights.

However, after entering the second 100m, the situation on the field will change, and athletes will choose different running methods according to their respective conditions.

The outermost Zhang Guan must be the first to enter the straight track, but his rhythm has not changed, and it is still the same as the curve.

"Zhang Guan's rhythm hasn't changed!" Everyone had their eyes lit up. At this time, everyone has already guessed that Zhang Guan was an athlete who prefers to use this type of running method.

Immediately afterward, other athletes also entered the straight track. At this stage, the speeds of these athletes are similar, but the starting times are different. It will be sooner or later.

The frequency of Varina's footsteps has not changed, but the pace of his steps has increased significantly. Other athletes will also try to take larger steps in the straight track, but it seems that Varina's pace has changed so obviously. No, this is a unique technique of Varina.

After all, Varina is a white athlete. He is no match for black athletes. The reason why Varina can become the first person in the world at 400 meters is mainly due to superb technique and speed endurance.

Since Michael Johnson retired, the 400-meter level around the world has fallen into a regression. For a long time, black athletes used to run physically, and Varina was a white man. With this identity, he dominated the 400-meter sprint so that everyone could pick up the technique again, and when the black athletes also have superb technique, even Varina can no longer maintain the dominance. For example, in 2006, it was unbelievable for athletes to run within 44 seconds. In 2015, nine years later, in the world's top competitions, if athletes could not run within 44 seconds, they could not even get a medal.

In this straight track, as a white athlete, Varina relies on technique, and black athletes rely on physical talent and speed. In addition to Zhang Guan and Varina, other black athletes have begun to increase their rhythm. Among them, Jamaican Blackwood and Simpson ran the fastest. Both of them began to run at this stage.

In the second 100-meter straight track, athletes who chose conservative running took about 11 seconds, and athletes who chose speed-up running took about 10.50 seconds. Varina's technical flow, although rhythmic, the changes are not big, but it can be made up for 10.50 seconds through technique. For athletes who choose the sprint method, they spend about 10.30 seconds.

Of the athletes participating today, no one chose to choose a conservative running method in the second 100-meter stage. They either speed up slightly, or choose to sprint, or followed Varina's technical flow, so at this stage, Zhang Guan started to fall behind.

"Blackwood, start speeding up! Varina! Simpson's speed is very fast, he is chasing forward!" The narrator has begun to ignore Zhang Guan, as a professional sports commentator, even if the athletes have relative positions in front and back, He can also see that Zhang Guan is behind at this stage.

Yu Gui 's performance is very calm. He knows that Zhang Guan's running style will only explode in the last 100 meters, so the trailing behind is normal, Yu Gui is used to Zhang Guan's trailing behind, and Yu Gui feels that Zhang Guan seems to be faster than usual today, which means that he will fall behind in the 300 meters.

The third 100-meter curve is a very critical distance for athletes, and it is also a reflection of athletes' running style and tactics.

"Zhang Guan's rhythm has not changed, he still hasn't increased his speed!" Some coaches in the viewing area frowned. According to normal circumstances, in the second 100-meter, the athlete who takes a conservative run will start to sprint from the corner, and Zhang Guan does not do so.

"Does Zhang Guan want to wait until 250 meters to start sprinting? Michael Johnson's traditional running method? This running method requires a lot of explosive power, speed, and speed endurance. Zhang Guan's speed and explosive power are naturally very powerful, but what about speed endurance?"

At this time, as a guest, Michael Johnson also noticed Zhang Guan.

"This is the way I ran early in my sports career!" Michael Johnson made a judgment immediately. In the late 1980s and early 1990s, Johnson used this kind of running method, and until the middle and late 1990s, as Johnson's technique became better and better, he slowly started changing the running method. The speed was slightly increased in the second 100-meter stage, but the sprint point behind did not change much.

Varina ran into the corner, and his running pace suddenly became much smaller, and his pace became faster. After entering the curve, the speed is increased first and then adjusted in the middle of the curve. This is the technical characteristic of Varina. Often at this stage, he will rush to a more advanced position.

Bahamas athletes Brown also entered the corner, his rhythm slowed down a bit, this is being adjusted.

Jamaican athletes Blackwood entered the corner directly with a sprint, and instead of slowing down, he got faster. He uses a mid-range running method, which will lead between 200 meters and 300 meters, but during the last 100 meters, he will have insufficient physical strength.

But his compatriot Simpson also slowed down after entering the corner, he began to adjust the state of his body and then prepared for the final 100-meter sprint.

The beauty of the 400m sprint lies in the choice of different tactics. Before the final sprint, no one knows who the championship belongs to. The first athlete to enter the final straight runway may become the last athlete in the game; many times the second, third, or fourth athlete who enters the final straight runway is the final winner.

As the athlete enters the second corner, the different tactical running styles chosen by each person are gradually revealed, and the difference between the front and back distances of the starting position will gradually be smoothed out. The movement distance of the athletes is the same, and the person who first enters the final straight track is the leader.

At 250 meters, half of the curve, Varina was a little slower, he started to adjust, but in fact, the adjustment process is extremely short, he will sprint before entering the final straight, when he enters the straight, he would have speed ​​up completely.

In contrast, Harris from the United States, Brown from the Bahamas, and Taylor from Canada also started to choose to sprint. Jamaican Blackwood's advantage has gradually been eroded, and Simpson has begun to fall behind.

However, Zhang Guan, his rhythm still has no change, he is running without rushing, at this time although he is in the outermost lane, it can be seen that several athletes on the inner race track have already kept pace with him, or has run ahead of him, which shows that Zhang Guan has fallen behind.

"It seems that our world's first flying man is not good at running 400 meters! But we still want to congratulate him, after all, he is the first athlete to participate in two events in the same Golden League!"

At this point, in the eyes of ordinary audiences, Zhang Guan is still the "successful athletes".
