Then after rigorously analyzing the data, you can draw a conclusion-

Through scientific analysis of Chen Juan's starting posture adjustment, it can be seen that the change of the arms bent before starting and the elbows are closer to both sides of the body has brought significant improvements in the swing speed of the arm, muscle activation and force, and starting acceleration performance.

The structural characteristics of a woman's body determine the argument that her center of gravity is relatively low and closer to the central axis of the body.

This chapter is not over, please click on the next page to continue reading! That's what you see now.

When activated, the arm bends and the rotation radius r decreases. With the same muscle force, a greater angular acceleration can be obtained!

This allows the arm to swing more quickly!

Provides greater initial acceleration for the start!

Immediately after going out.

Four steps of gold.

During the start stage of starting, the female body structure with a low center of gravity combined with the starting of a bent arm can achieve efficient transmission of strength.

When Chen Juan pushes the ground with her feet to produce a back pedal force, the low center of gravity allows the body to more stably transmit this force along the central axis of the body.

at the same time.

The rapid swing of the curved arm can generate a forward and upward pulling force, which cooperates with the pushing force of the lower limbs to form a more coordinated joint force direction.

This direction of force is closer to the direction of the body's movement, reducing the decomposition and loss of force during the transmission process.

Enables more power to be effectively used to push the body forward.

Of course it's faster!

At the same time, there is an additional discovery, that is, the posture of low center of gravity and the starting movement of the bent arm require specific neuromuscular control modes.

In a research report at Sushen Laboratory, it is stated-

In this case, the nervous system can more accurately activate the muscle groups involved in the starting lineup.

Including the quadriceps femoris, gluteus maximus, upper limb deltoid muscles, pectoralis major muscles, etc.

Under the coordinated control of nerves, these muscle groups can contract in a more coordinated order and force.

Improves muscle productivity.

This will generate greater explosive power at the moment of starting.

Enable the body to quickly get rid of the state of static.

Obtain a faster initial speed.

That……

How can you not be happy?

There is really no opponent in the country.

It is difficult to get along well in actual combat.

Finally moved to the international competition.

Chen Juan can show her skills!

After going out ten meters.

It's the acceleration zone.

Taking advantage of the female body structural characteristics, the gender characteristic of its relatively low center of gravity and closer to the central axis of the body.

More than just startup.

Acceleration zone.

It will also be more powerful and outstanding.

Like this one you see now.

Bang bang bang bang bang bang bang.

Chen Juan took advantage of the advantages of low center of gravity and curved arm starting in the acceleration stage to continue the effect.

After entering the acceleration phase, the advantages of low center of gravity and bent arm start are still significant.

A low center of gravity can continuously maintain the stability of the body, allowing athletes to better control their body posture during the acceleration process and avoid excessive fluctuations or deviations in the center of gravity caused by increased speed.

At the same time, the kinetic energy brought by the curved arm can provide the body with additional forward thrust, and through reasonable adjustment of the rhythm and amplitude of the swing arm, it maintains good synchronization with the acceleration and thrust movement of the lower limbs.

This coordinated cooperation between upper and lower limbs can effectively maintain the body's acceleration and enable the speed to be continuously and rapidly increased.

Bang bang bang bang bang bang bang.

"Chen is too fast?! Is this the startup acceleration that a big-size girl should have?"

"She's like a big-size fighter!"

This explanation is very beautiful.

But some people are dissatisfied with it after hearing it.

"Large size girl?"

"Your whole family is a big size girl!"

"My sister Juan is called tall and thin!"

"I know nothing!"

This was naturally what Zhou Bing said.

His current ability to protect his calf.

Not ordinary.

Chen Juan continued to accelerate.

Twenty meters later.

From the perspective of energy metabolism!

The combination of low center of gravity and curved arm start can also help optimize energy consumption.

A low center of gravity reduces unnecessary ups and downs of the body in the vertical direction.

Reduces the energy consumed to overcome gravity.

The optimization of the movement also reduces the distance of the arm swing and air resistance, thereby reducing the waste of energy.

This allows Chen Juan to use more energy to accelerate the body during the acceleration process.

The energy utilization efficiency is improved, and maintaining high-speed running provides energy and is also guaranteed.

That……

How can you not be happy?

Bang bang bang bang bang bang bang.

Shooting on the way.

Chen Juan's overall speed surged.

When running on the way, the center of gravity of your body is stable.

The stride is always kept in a large state, and the pace is light and elastic.

Bang bang bang bang bang bang bang.

Speed ​​zone.

Chen Juan can move forward efficiently with the reaction force of the runway every step.

All parts of the body cooperate with each other.

Just like a precision instrument running at a high speed, it can continue to run at a stable and high speed state.

Don't give your opponent any chance to overtake.

Firmly control the rhythm of the game.

Entering the second half of the speed stage.

Further explore the potential of leg muscles.

The power to push the ground has reached a higher level.

The arm swinging movement is more rapid and powerful, driving the overall speed of the body to a higher peak.

During this stage, Chen Juan continued to consolidate her lead.

Leave the other players far behind.

Step steadily towards the throne of champion.

No Brown.

No Fraser.
