The two men rushed into the vicinity of fifty meters like two lightnings.

They are ahead of everyone now, and Powell is a little unable to catch up here and is left behind.

Even Powell's shot is good enough, and his career is the best.

But he was still slightly pressed behind.

Of course, if he wants to get a medal, he must be fierce here.

Otherwise there would be no chance.

Lao Bao didn't know where he got the strength here, but he also followed these two people and began to stimulate their phosphate system.

Let it reach its maximum instantly.

"It's coming! A very fast confrontation!!!"

Green shouted in his live room that this is one of the most important points of this game.

If Su Shen is out of trouble, then the advantages established before will probably disappear.

It was reduced by a huge amount.

Then it is absolutely impossible to fight Bolt's future later.

Therefore, Su Shen also has no choice here.

Bolt broke out.

He will also explode.

This chapter is not over, please click on the next page to continue reading! Because of its fault tolerance rate.

It's lower than the black lightning around you.

Extremely fast.

liberation!

All three of them drove their own speed zone almost at the same time.

Bolt has nothing to say. He is the strongest one. It’s not surprising that he has exploded in any way in the big competition year.

A stable six-second burst of over three, and the burst is the most dazzling one among everyone.

It was like a black light thunder suddenly raged from the sixth path.

This slightly angry feeling actually made Bolt, who was not so lazy and lazy.

Entered a best condition.

Seeing this, Mills clenched his hand and slapped his thighs suddenly.

alright.

It's OK!

There is no problem with the outbreak now, and no one can withstand it!

...

When we returned to winter training, Randy told him a point, which was also a point where the gap between him and Bolt was huge.

"Su, look at your extreme speed zone. The change in the knee angle of the support leg of Bolt's support leg is 13 degrees from the moment the vertical stage is vertical to the rear kick off the ground, while your knee angle has almost no change. The change in the knee angle of the support leg is large, which means that the force of the support leg is large during the rear kick off stage."

“What problems will this bring?”

"This will allow you to push back and leave the ground to support the legs and knee angles at a time, thereby reducing the rise and fall of the body's center of gravity, so that the greater the horizontal acceleration force of the body, ensuring the straightness of the running; on the contrary, the smaller the knee angle of the support legs, the less obvious the kicking and stretching. The vertical force of the body's center of gravity is increased instantly, and the upward rise and fall of the body's center of gravity will also increase, causing the direction of the support legs to extend, which will reduce the horizontal acceleration force of the body."

"It can be seen that the change of the knee joint of the support leg during the running during the sprint directly affects the effectiveness and economicality of supporting leg muscle work throughout the rear pedal stage; the knee joint retardation and buffering amplitude of the support leg are proportional to the rear pedal effect, and the angle of the knee angle of the support leg during the rear pedal will have a greater impact on the rear pedal force."

"This shows that compared with your hip-sending skills and abilities, the biggest difference between you and Bolt on the way is not on hip-sending, but on your back pedal. Although the importance of back pedal has dropped significantly compared to the 1980s and 1990s, this does not mean that it is not important, especially when you are comparing with Bolt, there is such a big gap."

"Of course, this is probably determined by talent and physiological conditions, and it is very likely something you can't change in your entire life."

"You have to be mentally prepared for this."

...

Su Shen still remembers this passage freshly.

Therefore, the biggest problem of this game only starts from the extreme speed zone.

It's not just a simple lead.

In other words, the front is all about their own advantage areas, at least the advantage points will not be too low, and it will not give Bolt a chance to have too much gap.

But it's at the extreme speed zone.

That's really...

When the two people's advantageous areas completely begin to change.

At this time, he had to think about how to start facing Usain Bolt's crazy counterattack.

He thought about this question for a long time, and perhaps he began to think about it when he was still there.

He also dreamed of this shot countless times in his dream.

Then, there is no hesitation at all.

At this time, I was also hesitant.

First of all, the improvement of support.

This is the first point Su Shen thought.

Modern sprinting is actually based on the hip joint of the human body as the axis, the lower limbs as the main one, and the upper limbs and the body as the auxiliary one. Then Randy gave the angle of the knee to swing the legs during the moment of landing and the vertical stage, it can be seen that Bolt's swing the knee angle is obviously smaller than the angle of the knee to swing his legs during these two stages. During the moment of landing and the vertical stage, Bolt's swing legs is a single pendulum movement with the center of gravity as the suspension point. The sufficient folding of the big and small legs can shorten the swing moment and speed up the swing speed. This has a very positive impact on shortening the single step time and increasing the pace frequency.

With such a large stride, he is still a stride frequency athlete.

It shows that his talent is really full.

Since your swing legs are folded from the back of the body and swing forward to the support legs entering the vertical stage, the angle of the swing legs is larger than that of Bolt's knee, if you reduce the angle of the swing legs before folding the swing legs...

Will it work?

There will definitely be, but how to do it, how to reduce the angle of the knee swing before folding the swing leg, while maintaining the stability of the rest of the technical body?

This is the biggest problem.

Sprinting has never been a single mechanical exercise.

After Su Shen entered the extreme speed, when he kicked back and left the ground, the swinging legs were in a high swing state. In an instant, the knee joint was lifted up to "with hips to support the legs" and the calf naturally opened; when the knee joint was lifted to the highest point, the thighs were pressed down actively, and the calf actively "whipped" to the ground with the thighs pressed down.

Because the raised and actively pressing of the knee joint of the swing leg "pulls the ground", it not only increases the movement range of the human body, but also increases the pace of progress. This is a concrete manifestation of the rapid and powerful swing of modern sprinting techniques. In the past, Su Shen was trapped by insufficient physiological and technical rhythm, so he did not raise his legs enough, resulting in a small space for active force in the swing leg, and the stride became smaller.

Then you only need to reduce the knee angle when the swing leg is folded forward at the moment of landing and vertical stages, shorten the swing moment and accelerate the forward swing speed of folding, so as to speed up the stride frequency; raise the knee joint of the swing leg instantly off the ground to provide space for the formation of good ground lifting technology, and naturally increase the force of the ground lifting, to promote the pedal with swing and increase the stride.

Immediately, quickly mobilize your "semi-folding technology" in the low heel recovery state, so that your back kicking legs can maintain a certain degree of flexion and have more flexion, so that you are qualified to talk about changes in knee angle.

Otherwise, the buckling degree of the rear pedal is not enough.

It can only be Dong Shi's imitation.

like water off a duck's back.

Make a laughing stock.

In this way, the calf is naturally half folded in the high swing of the thighs, and when the swing leg is swung to the highest point and pressed down...

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! The knee angle will be opened at the same time and will be opened in time.

Then quickly fit into the speed zone flexing technology that you also appeared in the speed zone.

This is because the flexural pedal rear pedal is originally conducive to the rapid folding of the rear pedal after leaving the ground.

It is naturally adaptable to folding technology.

After all, the swing speed of the swing legs of the "flex-punching" rear-punching technology is faster than the swing speed of the swing legs of the traditional rear-punching technology.

The "flexion and thigh folding" technology naturally has a smaller angle, which increases the folding force, shortens the swing radius, accelerates the forward swing speed, increases the tension torque of the flexor muscle, and increases the forward swing speed and amplitude of the swing legs.

Due to the different sizes of the knee angle, the forward swing speed will inevitably be different.

Therefore, the technical link of Su Shen is not independently prepared at all.

At this moment, Randy suddenly felt like she had realized something.

The whole person's eyes became astonished, and then excitedly seemed to be about to shine red.

He didn't know that Ralph Mann next to him was even more flooding than the red light in his eyes.

This is the combination of Su Shen’s preparation to deal with Bolt in the Speed ​​Zone—

The more advanced flex pedal-type rear pedal technology after self-improvement, low heel recovery, semi-folding, and further liberating super step frequency, hip stride liberation, five-in-one gift package, specially prepared for your black lightning, the great Usain Bolt.

oh.

By the way.

Su Shen burst out from his entire body with a rapid liberation.

This moment surpassed any time before him.
