Chapter 2007 What the hell...another crank start???
What's going on???
Why is this noise coming again?
Wen Yongyi, Liang Jiahong, and Xie Zhengye, who had just finished running, all turned their heads away at this time.
Look towards the starting line.
Good guy.
this.
Everyone, including Su Shen who looked over, was in a daze at this moment.
"I'll go, pancakes, am I right?" Zhao Haohuan already gave the answer in these words.
That's right.
What shocked the starting line again was none other than Zhou Bing, a member of the small team.
He shot and ran again without any surprise.
The key is that he now makes moves on the starting line.
It's surprising.
Even Lao Zhao looked like he had three big steamed buns stuffed into his mouth at this moment. You must know that when he looked at Xie Zhengye just now, he didn't have such an expression.
Because Xie Zhengye was a talented player who had been trained intensively and recognized by Su Shen. He did some earth-shattering things, and Zhao Haohuan was not surprised.
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 bit of a loser.
It's just relative to the talent of these people.
He seemed a little weaker.
This is just stating a fact.
But now.
Zhou Bing made this starting gesture at the starting line.
This is the source of everyone's surprise.
Because of the posture he is putting on now.
If it’s not the posture that Xie Zhengye put on just now, what is it?
"A crank start? Another crank start?"
"Damn it! How could he do it???"
Previously, there were only two people in Ersha Island, or rather the whole world, including Su and Zhao. Now, with the addition of Chen Juan as a female, there are three of them.
Suddenly there were two more.
It's really a bit unexpected.
Beyond expectation.
But just putting on this posture is of no use.
It still depends on whether you can apply it in actual combat.
This time.
It can be said that Zhou Bing pretended to be successful.
It’s been a long time since I enjoyed this feeling of being saluted with everyone’s attention.
This kid actually enjoyed it quite a bit.
He nodded towards Su Shen Zhao Haohuan.
A look of "you guys are optimistic".
Bang——————————
A gunshot rang out.
It's a mule or a horse.
They all have to be taken out for a walk.
Although they are all cranked-arm starts, if you look closely, they are still slightly different from Xie Zhengye's. When Zhou Bing starts with cranked-arms, his upper limb movements focus more on exerting force from his shoulders to drive the cranked arms to swing, as if starting
A set of sophisticated lever devices. And Xie Zhengye’s cranked arm start is more like a nimble bird flapping its wings.
At the moment of starting, the bending angle of his elbows is relatively stable. Through the coordinated contraction of the shoulder and back muscles, the power is efficiently transmitted, making the forward momentum have a unique rhythm, just like a drummer accurately hitting the starting drum beat.
I can see that the swing range of his elbow is slightly larger than that of Xie Zhengye.
This is a clever use of the changes in centrifugal force and centripetal force generated at different angles during the arm swing process.
Su Shen noticed that from the perspective of the sequence of muscle force exertion, when Zhou Bing started running, the middle and lower trapezius muscles and rhomboids on the back first exerted force, transmitting the force to the shoulders, and then the anterior deltoid muscles and biceps brachii.
The synergistic effect drives the curved arm to swing.
This sequence of force exertion made his starting movement look extremely calm at the beginning, like a heavy machine being started, with every link closely connected and orderly.
When he bends his arms, the angle between his upper arm and forearm is maintained 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.
, allowing him to better transfer the power of his lower limbs through his trunk to his upper limbs when he starts to push off the ground, converting it into forward propulsion.
Moreover, during the entire starting process, the change in this angle is linear and slowly decreasing, which means that it can continuously and stably output power during the long starting acceleration phase, just like an engine that releases energy at a constant speed.
Xie Zhengye is different. At the moment of starting, he mainly relies on the rapid contraction of the lateral edge of the pectoralis major and the anterior deltoid muscle to drive the upper arm to swing forward quickly. At the same time, the biceps and brachioradialis actively cooperate to make the forearm quickly keep up.
The angle between his upper arm and forearm is about 90-95 degrees at the start. The relatively tight angle allows him to explode at a huge angular speed at the moment of starting. His arms swing like a whip whipping quickly, instantly generating a powerful forward motion.
pull.
These two modes translate to running.
In fact, it is easier to take advantage of cadence.
One is more likely to take advantage of stride length.
It seems.
Zhou Bing has really honed his own crank arm driving method through so many years of failure.
Technology is dead, people are alive.
Able to make better use of technology.
You must combine your own physiological conditions and physiological advantages.
Zhou Bing's bent-arm start pays more attention to the gradual accumulation and stable release of energy. In his preparatory posture before starting, his muscles are in a state of moderate tension, just like a bowstring that is fully drawn but has not yet been fired.
When the starting signal is given, he efficiently converts the elastic potential energy and chemical energy of the muscles into forward kinetic energy through orderly muscle exertion and stable arm movements. The energy loss of each step is controlled within a very small range.
, like trickles that converge into a rushing river, pushing him to continue moving forward.
When the starting gun rang out, Zhou Bing was like a precision ejection device that had been triggered. The arm-bending movement started in an instant, and his shoulder muscles contracted rapidly. The deltoid and trapezius muscles worked together to drive the upper arm upward at an angular speed of about 3.5 arcs per second.
Swing forward.
At this time, the angle between the upper arm and the forearm is about 105 degrees. For the legs, the angle of the feet on the ground is about 50 degrees.
The body is slightly tilted forward about 12 degrees, the center of gravity is steadily moved forward, the head is kept on the extension line of the spine, and the eyes are focused 3 meters in front to establish a stable starting posture for subsequent acceleration.
Bang, bang, bang, bang, bang, bang, bang.
These seven steps.
It was definitely the best start of ten meters since Su Shen watched Zhou Bing run one hundred meters.
It seems.
Zhou Bing really mastered the crank start.
It's not a half-baked product, and it's not a bluff.
This chapter is not over, please click on the next page to continue reading! It’s true...
There is a breakthrough.
Speed up and run.
Entering this section, Zhou Bing's bent arm swing frequency increases, about 4 times per second, which accelerates the body rhythm. The upper limb swing amplitude increases slightly, and the forward and backward swing angle reaches about 40 degrees, which effectively maintains body balance and increases propulsion.
If you look carefully at this place, you will find it.
More like the shadow of Su Shen.
In fact, this is normal.
Didn't Zhou Bing originally start from Su Shen, whom he studied earlier, and Zhao Haohuan, who studied later? Now, after training for so many years, he already has his own routine.
It's not just a simple combination.
It's just that Su Shen's running method was always bad and not in place. It 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 was very good at starting bursts. This problem has always been
Can't solve it.
It's not like Su Shen didn't take care of this "ordinary person's experimental specimen" that he brought along along the way. The crux of his current problem was immediately revealed...
Want to solve it.
It's not difficult either.
There is a magic elixir.
As long as it can be done.
That will definitely improve his performance and even his upper limit by a big margin.
That's the crank start.
What a pity.
He had already told Zhou Bing about this truth.
It's just that Zhou Bing has never been trained well.
Fortunately.
He didn't give up either.
In fact, Zhou Bing originally wanted to give up, but when he saw that his girlfriend Chen Juan, a girl, had mastered this technique, he really felt a little shameless, so he could only grit his teeth and continue to hold on.
What's more, if he can't practice it.
That is within the entire small team.
The only person who doesn't know this signature technique.
Xie Zhengye is growing very fast now, and he is really afraid that one day he will be the one to beat him.
Think of this.
Zhou Bing could only grit his teeth and persist.
Fortunately, the emperor paid off his hard work.
After so many years of persistence.
Finally in this year’s winter training.
Let him enlighten.
I don’t know that practice makes perfect.
Still had a sudden epiphany.
Anyway, just all at once.
Found the feeling.
He also kept hiding it.
Just for this winter training test.
Take it out and let everyone admire it.
Especially Su Shen and Zhao Haohuan were impressed.
Prove that I know someone.
Nor is it just a bastard role in a small team.
Thirty meters.
At this stage, Zhou Bing's arm-curving movements become more smooth and powerful. The angle between the upper arm and the forearm begins to gradually decrease, reaching about 95 degrees, which makes the arm swing radius smaller and the angular speed further increases to about 4.2 radians per second, thus improving the
The swing arm efficiency.
look up.
Run on the way in.
The arm swing frequency of about 4.3 times per second and the continuously increasing arm swing force make the upper limbs like high-speed running pistons. At this time, the angle between the upper arm and forearm is maintained between 90 and 95 degrees, and the front and back swing angle is about 42 degrees. The legs
The pedaling angle is still maintained at about 48 degrees.
Fifty meters.
Explodes in six seconds.
As for the legs, the kicking angle is adjusted to about 46 degrees.
The adjustment of the kicking angle is to adapt to changes in speed and energy supply and optimize the distribution of force in the vertical and horizontal directions. During muscle contraction, the length-tension relationship of the muscle plays an important role. A suitable kicking angle can make the legs
The internal muscles are in an optimal length-tension state when contracting, thereby producing maximum force output.
Don't say it.
Zhou Bing has been outstanding among other things in recent years.
But I managed to practice it anyway.
Also called a solid one.
After adding the crank arm start.
Significant growth ahead.
Then you can run faster on the road.
Get greater top speed.
This is used to maintain more speed in the second half of the race.
Although he doesn't have the talent for speed and endurance like Xie Zhengye, he still has the talent for endurance.
That's enough.
Bang, bang, bang, bang, bang.
Zhou Bing walked steadily.
Crossed the finish line.
Take a look at the results.
Oh.
10.25s.
This is all going straight to Liang Jiahong.
You'll know it at a glance.
This year’s winter training is officially tested.
Worth the wait.
After Zhou Bing finished running, he did not stop and ran directly towards Su and Zhao. His expression seemed to say——
Praise me.
Why don't you praise me?
Praise me quickly!
Su Zhao looked at each other.
Su Shen hasn't spoken yet.
Zhao Haohuan was neither salty nor bland. He put away his surprise and said calmly:
"Well, not bad."
"You have finally reached the average level of our small team."
"It didn't embarrass us too much."
"Before, I was worried that you wouldn't be able to learn your talent."
"I didn't expect it to be okay. The last one is better than not learning at all."
Zhou Bing:......
Look at Su Shen.
I hope Su Shen can say something nice.
But Su Shen originally wanted to say.
See him like this.
Still decided not to let it go too far, so he followed Lao Zhao and nodded: "Keep up the good work, don't lose to Sister Juan.
Zhou Bing:......
Snap.
Hanging heart.
It suddenly broke into pieces.
Thinly chopped.
But the impact he brought.
But compared to what Zhao Haohuan said, it is much larger on Ersha Island.
What number is this?
The rest of the people’s inner thoughts are——
Start with a bent arm.
It will be mass produced this year.
It’s a bargain price, right?
ps: More updates will be added, please vote hehe...
