In the huge Helsinki Olympic Stadium, when the sound of the starter's "ready" sounded, it seemed to fall silent all of a sudden.

In the stands on the sidelines, Jax Thelin, Jason Gaby and other athletes who came to watch the game couldn't help but lift their spirits after the sound of this voice, as if they were in front of the starting line at this moment.

It's an athlete's instinctive response, and the body responds reflexively when the sounds of each are in position and ready to play.

In the arena, the eight runners in front of the starting line suddenly got up from the squat and made a squatting start.

The 400-meter race is not as demanding as the 100-meter and 200-meter race, but this is the venue of the World Championships, and the semi-finals of the second shot are of great importance, and all the athletes in the stadium are in a state of complete tension at this moment.

Ye Qin's breathing was slender and slow, maintaining a high degree of concentration, his body was slightly tense and slightly relaxed, and the state of his body was like a spring that had been suppressed to the extreme, just waiting for the final outburst.

Syllable!

Crisp race guns rang out!

Ye Qin stepped on the pedals of the running aid with both feet and suddenly exerted force, and the whole person shot out, swinging his arms quickly and starting to run.

The pace and pace of the 400m has not really come in handy for months, and although he let go of the run in the preliminaries, he was limited to the strength of some opponents and the retention of some athletes, and he ran to the front with ease in the final stage, and he could not have the best burst.

This group is the semi-finals, and in comparison, the strength level of the players and the mentality of the competition have reached a new level.

After the start, Ye Qin began to accelerate rapidly, with a large and powerful stride, among the sprinters of one or two hundred meters, Ye Qin's current starting reaction and starting acceleration are relatively weak players.

But in the 400-meter race, his current start and acceleration are already at an upper-middle level.

The 400-meter runner has requirements for both starting and accelerating, but in general, it is not as high as 1200 meters, after all, the ability to maintain speed in the second half of the race is often the key to victory.

10 meters ...... Thirty meters...... Fifty meters......

The rapid pace was almost only an afterimage in people's sight, and after fifty meters, Ye Qin gradually increased his speed to the high-speed stage of running on the way.

This is also the best time for him to enter the high-speed stage, many of the top 100-meter athletes can increase their speed to the high-speed stage in twenty or thirty meters, and reach the peak of their absolute speed at fifty or sixty meters.

Ye Qin is now running 200 meters, and he can almost enter the high-speed stage at thirty or forty meters, but with his technical characteristics, the real maximum speed is still around eighty or ninety meters, which is almost the peak of his personal absolute speed.

Meanwhile, American Darrod Williamson in lane 5 and Canadian Tyler Christopher in lane 6 are also picking up their speeds.

Black athletes have a strong explosive ability in the first half of the race, and although the 400m event is not decided by the start, a good first-half explosive ability can also occupy a clear advantage.

After just fifty or sixty meters, the fifth lane of the American Darrod Williamson and the sixth lane of the Canadian Tyler Christopher almost overtook the front, on the other side, the first lane of the British Timothy Benjamin was also very strong, and soon with his own strong strength, he gradually caught up in the outer lane.

At this time, the pattern of the players on the field has not changed much from the start to the present, and the position change of each player is only compared in relative positions.

The three American, Canadian and British competitors all began to gain an advantage with their individual strength, and Ye Qin was just starting to exert his strength at this stage, even if he was running in the 200-meter way, he was at about the same speed at this time, firmly following the three.

On the contrary, in the opening stanza, Sudanese Abubakr Ali, who was regarded as one of Yechin's main rivals, was not able to gain the advantage as easily as he had in '03 and '04.

It's not that Abubakr Ali has regressed, it's that he has a different strength against players, and he is no longer at the level of the World Junior Championships and the World Youth Championships, even if he won against Ye Qin two years ago, but now there is a big gap between him and Ye Chin.

80 meters, 90 meters, 100 meters......

In the blink of an eye, it was the first corner into the straight.

The 400m is a lap around the standard stadium, just two corners, and after the first corner, entering the straight, is also an important stage for many first-half runners to quickly improve their position in the entire semi-final group.

Yechin was no exception, and his pace was at its peak after entering the straight from the first corner. After eighty or ninety meters, he gradually entered the peak of his own running, and when he entered the straight stage, the speed was very fast.

Runners who run 400 meters do not need to be particularly top-notch and excellent in terms of absolute personal speed, but if they can maintain a relatively high speed, they will finish at an average high speed in a lap of 400 meters.

But after all, the sprint race is not a long-distance run, you can compare the pace to a lap by lap, 400 meters is not long, short is not short, many explosive players, in these 400 meters there may be several ups and downs of speed ups and downs, it is almost impossible to completely stabilize the uniform pace to finish the race.

Ye Qin originally belonged to the first half of the pressure more hateful, starting from the second corner to accelerate until the final sprint stage of the speed appeared, this running style made him in the entire 400-meter race, basically in the personal speed is relatively high, but definitely did not enter his strongest level.

And the original way of running, because of the pace in the first half, the speed is suppressed, and the physical fitness will be more abundant, and in the real sense, his personal speed and endurance in the second half of the race are not fully exerted.

And now, basically the first half of his race is almost at the level of 95 percent of his 200 meters, raising the speed, and then using the speed and endurance to stabilize the speed.

Therefore, on the field, after entering the straight stage, Ye Qin has gradually run to the front in relative distance, but at this time, the impact of the number of forward stretches has not passed, and many spectators watching the game have not been able to tell who has the advantage.

But some of the players in the stands gradually became thoughtful, although the distance was far, but basically the figures of the players could still be seen more clearly, and they could probably see that Ye Qin was exerting his strength in comparison with each other.

In the corners, he was almost in fourth place, but by the first straight, Yechin was almost in the top two.

The likes of Jason Gaby, Wallace Spearmon, Eusey Bot and Jax Thelin, who have played against Yechin, are not surprised.

Ye Qin's 200-meter run itself also relied on the second half of the straight to gain an advantage, and now compared to the distance, this time is just the stage of Ye Qin's strength.

To the surprise of these people, especially those like Jason Gaby and Yusse Bot, who had also run the 400m at one point, Yechin was in very good shape.

After the semi-finals of the men's 200m this year, the 400m run has been able to maintain this pace, which has to some extent included the young Asian athlete in his competition.

In athletics, when an athlete reaches a certain level, no matter where he comes from, as long as he has the strength to stand on the same starting line as himself, he will become a potential competitor in the next competition.

There is only one champion!
