I'm about to run on the bend.

At this time, Xie Zhengye began to take a step further and maintain the stability of the center of gravity of the body. The stability of the center of gravity is not only important in the starting process, but also in terms of acceleration, especially running on the way, maintaining the stability of the center of gravity of the body is also important for maintaining body balance.

In the starting of the step frequency curved arm, the high step frequency makes the body support time shorter.

If the body rises and falls too much at this time, the center of gravity will be difficult to maintain in a stable position and will easily exceed the support surface, which will cause falling or losing the rhythm of starting.

Yes.

It's still a big problem with the ups and downs of the body.

A question.

It can be eaten until now.

Really.

It shows that knowledge also requires cognition to improve and utilize.

Do this well.

Then... reducing ups and downs can keep the center of gravity of the body at a relatively stable height and position.

Used to reduce the possibility of losing balance in the body.

Allow yourself to move forward more steadily during acceleration and running on the way.

The way Xie Zhengye did here is:

Coordinate upper and lower limb movements.

Why do this?

Because the ups and downs of the body will also affect the coordinated movement of the upper and lower limbs.

During running, the swing of the bent arms of the upper limbs and the steps of the lower limbs are coordinated and coordinated to maintain body balance and generate forward motivation.

This coordination relationship can be disturbed when the body experiences unnecessary ups and downs.

For example, last year's Diamond League.

Xie Zhengye made this mistake.

Forgot to keep your body up and down, in order to maintain balance, the swing amplitude and rhythm of your upper limbs may change.

This will affect the pace frequency and stride length of the lower limbs.

This caused him to have poor pace frequency and stride matching on his lower limbs several times.

Although it is already good for ordinary people, it is already perfect, but as an athlete, you should just listen to it.

Believe it.

That's the big fool.

The field of competitive sports is perfect or not, and it always depends on the object of comparison and the level you are in.

If you put perfection beyond 20 seconds 50 and within 20 seconds 50, it is not perfect.

You can put it perfectly within 20 seconds and within 50 seconds.

There will also be imperfections.

This is the scientific research and sports spirit that you should have.

Su Shen has been practicing it on Ersha Island and promoting this concept and spirit. The results are still very significant, which has affected almost all the young people on Ersha Island afterwards.

What Su Shen asked him to do is... Reducing up and downward ups and downs can make the coordinated movement of the upper and lower limbs smoother.

The energy pushed by the curved arms of the upper limbs continues if it can better match the high step frequency of the lower limbs, providing the body with stable balance support and forward propulsion.

Then you run along the way.

It will also be faster and more stable.

Of course, there are other things to pay attention to here. If you have the right theory and direction, but don’t pay attention to the changes in the carrier itself, that’s not OK.

Su Shen told Xie Zhengye during training that when the body is up and down, the lower limb joints, such as knee joints, ankle joints, etc., will withstand greater impact.

According to the momentum theorem Ft = Δmv, where F is the force, t is the time of action, Δm is the change of mass, and v is the change of velocity. When the body falls, the sudden change of velocity will cause the joint to be subjected to a greater impact force.

So.

Reducing up and down can reduce the impact force the joints suffer in each step.

This reduces the possibility of joint wear and injury.

Joints are also a place for athletes to protect, and don’t think that you can do whatever you want when you are young.

How to do it specifically is Su Shen told him to maintain the normal movement trajectory of the joints.

This trajectory changes according to your body conditions, muscle conditions, physiological conditions, and constantly changing.

When needed, the champion model system is often used to calibrate.

Because during normal running, the movement trajectory of the joint is relatively stable and regular, but the ups and downs of the body will change the direction and movement angle of the joint, causing the movement trajectory of the joint to deviate.

Especially on curves.

Because it is not a straight road, it also has to withstand the double clamping of centripetal force and centrifugal force.

We must constantly adjust and not cause injuries to ourselves.

If Su Shen didn't say these and didn't tell him the answers to this aspect directly, he wouldn't be able to understand them clearly.

It is impossible to notice such aspects.

This is the benefit of having a version answer directly.

Many times, just by right direction and method, you may not be able to train athletes, because you have to consider other aspects, especially the injuries themselves.

As much as possible, make athletes scientific and irregular rules and avoid injuries.

Only then can you understand here that Su Shen is for the entire Ersha Island.

What a great sacrifice?

Bang bang bang bang bang bang bang.

Run on the curve!

At this time, only Dicks could keep up, but he ran on the curve because he had just returned from the season injury.

I dare not pull the horsepower in one breath.

This is why his results in history are not good.

Especially when I was about to come up and put some pressure on Xie Zhengye, Xie Zhengye was running on the curve and actually...

Run very smoothly.

Anyway, it's more than Dix's impression.

Much smoother.

This is because, under the guidance of Su Shen, he began to enter a more advanced dabbling.

That is, the balance between centrifugal force and centripetal force on the curve.

How to overcome centripetal force and centrifugal force in normal times?

Just come together.

No matter what the theory is, it is basically the same now.

But Su Shen told him...

When running on curves, athletes need to rely on centripetal force to overcome centrifugal force.

to maintain the track on the runway.

Yes.

Use centripetal force to overcome centrifugal force.

Use centrifugal force to react with centripetal force.

Damn it.

As soon as this was said, although Xie Zhengye didn't understand, he felt that he was not clear about it.

Yang Yaozhu, who had been studying in the next subject for so many years, was even more shocked by this... she almost couldn't close her mouth.

While they were still thinking about how to encourage them to face this curve, they had already thought of combining them, leveraging their strength to use each other for their own purposes.

Really.

The pattern is different.

It's simply.

The light sounds.

They all feel terrible.
