What's going on???
Why did this sound come again?
Wen Yongyi and Liang Jiahong, including Xie Zhengye, who had just finished running, all turned his head away at this time.
Look at the starting line.
Good guy.
this.
In addition to Su Shen who looked over, he was a little stunned at this moment.
"I'll go, pancake, I'm not wrong." Zhao Haohuan's words had already given the answer.
That's right.
The one who made the starting line start again was no one else, but Zhou Bing, a member of the small team.
He continued to run with no surprise.
The key is that he is now making moves at the starting line.
Surprisingly.
Even Lao Zhao seemed to have three big steamed buns stuffed into his mouth at once. You should know that when you saw Xie Zhengye just now, he didn't have such an expression.
Because Xie Zhengye was a talented player who was trained seriously and recognized by Su Shen. Zhao Haohuan was not surprised that he did something shocking.
But Zhou Bing...
It’s not that I look down on him.
It's just relative to the strength of these people.
He seemed to be a little dish.
It's just relative to these people's talents.
He seemed a little weaker.
This is just a statement of a fact.
But now.
This start gesture that Zhou Bing put out at the starting line.
It is the source of everyone's surprise.
Because of the posture he is posing now.
What is it that Xie Zhengye just put forward?
"Curved arm start? Is it actually another bent arm start?"
"Heavenly killed! Why would he do it???"
In the past, the entire Ersha Island, or the whole world, was only Su Zhao, and now the woman added a Chen Juan, and there were three in total.
Suddenly there were two more.
It's really unexpected.
Exceeding expectations.
But just posing this posture is useless.
It depends on whether you can use it in actual combat.
This time.
It can be considered that Zhou Bing was pretending.
I haven't enjoyed this kind of attention-grabbing ceremony for a long time.
This kid is actually quite enjoying it.
Nodded to Su Shen Zhao Haohuan.
He looked like "You guys are good."
Bang —————————
The gunshot sounded.
It's a mule or a horse.
They all have to take it out for a walk.
Although they all start with a bent arm, if you look closely, it is still slightly different from Xie Zhengye. When Zhou Bing starts with a bent arm, his upper limb movements focus more on exerting force from his shoulder to drive the bent arm swing, like starting a group of precision lever devices. Xie Zhengye's start with a bent arm is more like a lively bird flapping its wings.
At the beginning, his elbow bend angle was relatively stable. Through the coordinated contraction of the shoulder and back muscles, the efficient transmission of strength was achieved, making the forward momentum have a unique sense of rhythm, just like a drummer accurately hitting the drum beat of the starting point.
I saw that the range of swinging his elbows was slightly larger than that of Xie Zhengye.
This is a clever use of the centrifugal and centripetal force changes generated at different angles during the swinging arm.
Su Shen noticed that from the perspective of the order of muscle force, when Zhou Bing started, he first exerted force on the middle and lower trapezoidal muscles and rhombus muscles on the back to transmit the strength to the shoulders. Then the deltoid anterior bundle and biceps work together to drive the bent arm swing.
This order of force makes his starting movement appear extremely calm in the beginning stage, like a heavy machinery that is starting, with each link closely connected and orderly.
When he bent his arms, the angle between the upper arm and the forearm remained at about 100-110 degrees at the moment of starting. This relatively large angle can provide him with more stable support in the early stage, just like building a solid mechanical structure that allows him to better transmit the lower limb strength through the trunk to the upper limbs when starting and rushing the ground, and convert it into forward propulsion.
Moreover, during the entire starting process, the change of this angle is linear and slowly decreasing, which means that it can continuously and stably output power during a long starting acceleration stage, just like an engine that releases energy at a constant speed.
Xie Zhengye is different. His starting moment mainly relies on the rapid contraction of the lateral edge of the pectoralis major muscle and the anterior deltoid muscle, which drives the upper arm to swing forward quickly. At the same time, the biceps and brachioradial muscles actively cooperate to make the forearm keep up quickly.
The angle between his upper arm and forearm is about 90-95 degrees at the start. The relatively compact angle allows him to burst out with a huge angular speed at the moment of starting. His arms swing like a whip waving quickly, instantly generating a powerful forward pulling force.
These two modes are converted to running.
In fact, it is easier to take advantage of step frequency.
One is easier to take advantage of stride.
It looks like.
Zhou Bing has really honed a set of his own bent arm driving method through so many years of failure.
Technology is dead, and humans are alive.
Be able to better use technology.
It is necessary to combine your own physiological conditions and physiological advantages.
Zhou Bing's bent arms starts pay more attention to the gradual accumulation and stable release of energy. In his preparation posture before starting, his muscles are in a moderate state of tension, like a full bowstring but have not yet been fired.
When the starting signal is issued, he efficiently converts the muscle elastic potential energy and chemical energy into forward kinetic energy through orderly muscle force and stable bent arm movements. The energy loss at each step is controlled within a very small range, just like a trickle of water converging into a rushing river, pushing him to continue moving forward.
When the starting gun fired, Zhou Bing was like a triggered precision ejection device. The curved arm movement started instantly, and his shoulder muscles quickly contracted, and the deltoid muscles and trapezoid muscles jointly exerted force, driving the upper arm to swing forward at an angular velocity of about 3.5 arcs per second.
At this time, the angle between the upper arm and the forearm is about 105 degrees. In terms of legs, the angle between the feet is about 50 degrees.
The body leans forward slightly about 12 degrees, the center of gravity is steadily shifted forward, the head is kept on the spine extension line, and the eyes are focused 3 meters in front, establishing a stable starting posture for subsequent acceleration.
bang, bang, bang, bang, bang, bang, bang.
These seven steps.
Su Shen has definitely seen Zhou Bing run for the best ten meters since he ran 100 meters.
It looks like.
Zhou Bing really mastered the bent arm to start.
Not a semi-finished product, nor is it a bluff.
This chapter is not finished yet, please click on the next page to continue reading the exciting content behind! It is true...
There is a breakthrough.
Speed ​​up and run.
Entering this section, Zhou Bing's bent arms swing frequency is accelerated, about 4 times per second, which drives the body rhythm to accelerate. The swing amplitude of the upper limbs slightly increases, and the forward and backward swing angle reaches about 40 degrees, effectively maintaining body balance and increasing propulsion.
You will find this place carefully.
It's more like the shadow of Su Shen.
Actually, this is normal.
Didn’t Zhou Bing start with Su Shen who learned earlier, and Zhao Haohuan, who studied later? Now he has just been training for so many years and has already developed his own routine.
Not a simple combination.
However, Su Shen’s running method was not good or inadequate, which was even worse than the bankrupt version. It was simply a beggar version. Because of his running method and characteristics, he was not a person who started the explosion too well, and this problem could never be solved.
Su Shen was not without taking care of the "ordinary human experimental specimens" he brought along the way. He suddenly pointed out the crux of his current problem...
Want to solve it.
It's not difficult either.
There is a magic pill.
As long as it can be done.
That will inevitably increase his grades and even the upper limit by a large margin.
That is the bent arm start.
It's a pity.
He had already told Zhou Bing about this truth.
But Zhou Bing has never practiced well.
Fortunately.
He did not give up either.
In fact, Zhou Bing originally wanted to give up, but seeing that his girlfriend Chen Juan and a girl had won this technique, he felt a little shameless and could only grit his teeth and continue to hold on.
Besides, if he couldn't practice.
That's the entire small team.
The only person who doesn't know this signature technology.
Xie Zhengye is growing very fast now, and he is really scared and will take the blame one day.
Thinking of this.
Zhou Bing could only grit his teeth and persevere.
Fortunately, God lives up to the hard work of those who work hard.
After so many years of persistence.
Finally in this year's winter training.
Let him know.
I don't know if it's practice that makes perfect.
Still suddenly enlightened.
Anyway, it's all at once.
Found the feeling.
He has been hiding it all the time.
It's for this winter training test.
Take it out to make everyone look at you with admiration.
Especially, it made Su Shen and Zhao Haohuan look at each other with admiration.
Prove me, Mr. Zhou.
It's not a scheming bottle in the small team.
Thirty meters.
At this stage, Zhou Bing's bent arm movements became smoother and more powerful. The angle between the upper arm and the forearm began to gradually decrease, reaching about 95 degrees, which made the arm swing radius smaller and the angular velocity further increased to about 4.2 radians per second, thereby improving the efficiency of the arm swing.
look up.
Run on the way.
The swing frequency of about 4.3 times per second and the continuous increase in swing force make the upper limbs look like a piston running at high speed. At this time, the angle between the upper arm and the forearm is maintained between 90 and 95 degrees, and the forward and backward swing angle is about 42 degrees. The legs are still pressed at about 48 degrees.
Fifty meters.
Six seconds of explosion.
In terms of legs, the pushing angle is adjusted to about 46 degrees.
The adjustment of the pedal angle is to adapt to changes in speed and energy supply and optimize the distribution of force in the vertical and horizontal directions. During the muscle contraction, the length-tension relationship of the muscle plays an important role. A suitable pedal angle can make the leg muscles in the optimal length-tension state when contracting, thereby generating the maximum force output.
Don't say it.
Zhou Bing has been outstanding in other years.
But at least I practiced.
Also called a solid one.
After the bent arms were added to start.
The previous growth rate is significant.
Then you can enter the way faster and run.
Get a bigger speed.
This is used to maintain more speed values ​​in the second half of your journey.
Although he does not have the speed and endurance talent like Xie Zhengye, he still has the endurance talent.
This is enough.
Bang, bang, bang, bang, bang.
Zhou Bing took steady steps.
Crossed the finish line.
Look at the results.
Oh.
10.25s.
This is all chasing Liang Jiahong.
You can tell at a glance.
This year's winter training formal test.
Worth looking forward to.
After Zhou Bing finished running, he did not stop and ran directly to Su Zhao and the other two. His expression seemed to be saying-
Praise me.
Don't praise me yet?
Praise me quickly!
Su Zhao looked at each other.
Su Shen hasn't spoken yet.
Zhao Haohuan was neither salty nor light, she put away her surprise just now and said lightly:
"Yeah, not bad."
"You finally reached the average level of our small team."
"It's not too embarrassing for us."
"I was afraid that you wouldn't be able to learn your talent before."
"I didn't expect it to be OK. The last one is better than not learning."
Zhou Bing:...
Looking at Su Shen.
I hope Su Shen says something nice.
But Su Shen originally wanted to say.
Seeing him like this.
I decided not to let go too far, so I followed Lao Zhao and said, "Still work hard, don't lose to Sister Juan.
Zhou Bing:...
Pick.
A hanging heart.
It broke suddenly.
Sparsely broken.
But his impact.
It is much bigger than what Zhao Haohuan said on Ersha Island.
Which one is the first?
The inner thoughts of the rest are-
Start with bent arms.
This year we will need mass production.
It's a bargain price, right?
