The arms swing more quickly, and the triceps and biceps continue to exert force during the swing to maintain body balance and forward momentum.

The forward angle of the body is reduced to about 10 degrees, reducing wind resistance, and the center of gravity is steadily advancing forward.

Chen Juan's thigh muscle group stably outputs strength, the calf muscles complete ground cushioning and thrusting in a very short time, and the contact time between the soles of the feet and the ground is extremely short.

The amplitude of the arm swing is slightly reduced but the frequency remains unchanged. It is perfectly coordinated with the leg movements, and the body remains streamlined. It uses the aerodynamic principles mentioned by Su Shen to reduce wind resistance and maintain speed improvement.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

Two people actually killed...

Difficult to solve!

Fraser's supporters were stunned.

Chen Juan's supporters were also shocked.

Sister Chen Juan...

Can you actually compete with Fraser, the startup acceleration superman?

It's really...

So handsome!!!

Come on, the little girls on Ersha Island come on crazy.

Although they didn't have the chance to compete in the Diamond Competition.

You can see your idol and Fraser fighting...

still.

Feeling hot and boiling.

The two gradually looked up.

Running along the way.

The hip muscles such as the Fraser gluteus medius are involved in maintaining pelvic stability and allowing the leg strength to be transmitted better.

Chen Juan's quadriceps and hamstrings work alternately at a stable rhythm, while the calf triceps maintain elasticity and stretch.

Fraser breathed rapidly and regularly, which was to meet the oxygen consumption of high-intensity exercise. Her body's center of gravity moved smoothly along a straight line, with stable and efficient stride width and pace frequency. The swing of her arms and legs were as precisely as mechanical gears.

Chen Juan's gluteus maxillary contraction reached its peak, and cooperated with the quadriceps to optimize the stomp angle to about 50 degrees to provide maximum horizontal thrust.

The external oblique muscles and internal oblique muscles participate in pelvic rotation to enhance the transmission effect of leg strength.

Speed ​​zone.

Six seconds of explosion!

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

The muscles in Fraser's ankle joint coordinate to accurately control the ground and thrust to reduce energy loss.

Chen Juan's head remains stable and her breathing rhythm is accelerated, providing oxygen guarantee for high-intensity work of muscles.

Fraser's calf muscles quickly alternately contract and relax, the arm swing speed increases, the triceps and biceps cooperate to maintain body balance and forward momentum. The forward angle of the body is reduced to about 8 degrees, and the center of gravity moves forward smoothly.

When Chen Juan transitions to the highest speed, her nervous system efficiently regulates muscles and contracts and relaxes at extremely high frequency.

The thigh muscles stabilize the output of strength, the calf muscles complete the ground buffering and thrust cycles in a very short time, and the contact between the soles of the feet and the ground is completed almost instantly.

Fraser's arm swing amplitude is finely adjusted but the frequency remains unchanged, and it is in harmony with the leg movements.

Chen Juan's deep buttocks, such as piriformis muscles, participate in stabilizing the pelvis and allowing the legs to be efficiently transmitted.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

Enter the sprint area!

"The final sprint! Fraze and Chen Juan almost..."

“Almost all the way!”

"No difference!!!"

But this time begins.

The wind direction is about to turn.

Not just Su Shen.

The rest of the people from Ersha Island also looked like this.

"Frazier is going to be nervous."

"Yes, it's time for her to be nervous."

Zhao Haohuan and Zhou Bing both said at the same time.

They all saw it.

If you can't get an advantage here.

Then Fraser's back may not be able to compete with Chen Juan.

There was no problem before, because Chen Juan's hard power had not improved before, and there was a fundamental difference between level and Fraser.

But as Chen Juan's hard power continues to improve.

The gap between her and Fraser is getting smaller and smaller.

Just like Guy, although his future is still fast compared to ordinary people, he is still very strong.

But when the hard power and gap of this ordinary person gets smaller and smaller.

The comparison of the areas of expertise that are formed before and after will become more and more obvious.

It was not obvious before, because it was suppressed with hard power. To put it bluntly, someone’s shortcomings are not worse than yours.

Until you get closer to his hard power.

Then your advantages can be truly demonstrated.

That's what Chen Juan is now.

Fred was thinking that it would be more and more difficult for him to rely on his hard power to suppress Chen Juan, or not to lose his disadvantage.

Don't forget.

He is now also an Olympic medalist.

Even if you are a gold medal.

It's not that it's completely powerless to fight back.

At least now.

The power to fight back is still there.

Chen Juan is still stable, the quadriceps and hamstrings work alternately at a stable rhythm, and the triceps of the calf maintain elasticity and strength.

On the contrary, Fraser,

Although the speed is still fast,... the accumulation of fatigue makes her legs muscles slightly less explosive.

The contraction strength of the quadriceps femoris begins to weaken, but it still relies on muscle endurance to maintain exercise.

But how long can it last?

She herself didn't know either.

Frazier was not originally a super expert in the future.

Her height.

It restricted her.

Ten meters passed.

Bang, bang, bang, bang, bang.

Bang, bang, bang, bang, bang.

Chen Juan still outputs stably.

The muscle fatigue in Fraser is aggravated and the speed is significantly reduced. The leg muscles are sore, and the frequency of contraction of the quadriceps and hamstrings will also decrease.

Then the stride decreases.

The forward angle of the body increases to about 15 degrees.

They will come one after another.

The arm swing force and speed are reduced.

Body balance begins to be broken.

Even the body begins to have shortness of breath and is unbalanced from the body's energy supply and metabolism.

Start relying on muscle memory and willpower to maintain the running rhythm.
To be continued...
