Bang bang bang bang.

Three steps in gold.

Su Shen’s firepower is fully opened.

Now.

It's time to look at the butt.

During the 100-meter sprint, the activation time of the buttock muscles plays a key role in horizontal displacement. Accurate muscle activation time can ensure coordination and cooperation among various muscle groups, thereby achieving efficient power transmission and horizontal promotion.

At the moment of starting, the hip muscles need to be activated quickly to generate powerful ground pushing force to push the body forward.

If the hip muscles are activated too late, it will lead to slow starting reactions and affect the initial acceleration and the starting speed of horizontal displacement.

When the legs swing backwards to prepare to push the ground, the buttocks should be activated moderately in advance to reserve energy for the pushing ground.

At the moment of pushing the ground, the buttocks muscles reach the maximum activation state, generating the maximum contraction force, effectively transmitting the force to the ground and pushing the body forward.

If the activation time of the hip muscles is inaccurate, it will lead to poor power transmission, reduce the efficiency of ground striking, and thus affect the speed and distance of horizontal displacement.

In order to increase the horizontal component force.

This step of activation must be done well.

Because the buttock muscles not only have the ability to contract and generate strength, but also have good elasticity.

This elasticity has made an important contribution to horizontal displacement assistance in the 100-meter sprint.

During running, when the legs hit the ground, the buttocks muscles will be stretched by ground reaction forces to store elastic potential energy.

Then, as the legs push the ground off the ground, the buttocks muscles quickly contract, converting the stored elastic potential energy into kinetic energy, increasing the strength and speed of pushing the ground.

This pushes the body forward horizontally.

The higher the mass of the gluteus maximus, the more efficient the use of this elastic potential energy, and improve the energy utilization efficiency.

Under the same muscle contraction force, greater horizontal displacement assist is obtained, thereby increasing the sprint speed.

Bang bang bang bang bang bang.

Continue to step out.

Continuously follow the steps.

In a 100-meter sprint, the stable and reasonable movement of the body's center of gravity is crucial for horizontal displacement.

The buttock muscles play an important role in maintaining the stability of the body's center of gravity and promoting it to move forward through control of the pelvis and lower limbs.

For example, now, during startup.

The contraction and suffocation of the hip muscles can adjust the tilt and rotation angle of the pelvis.

It will then affect the position and movement trajectory of the body's center of gravity.

When the hip muscles contract vigorously, they can pull the pelvis back and down, lower the center of gravity of the body and move forward, increasing the stability and strength of the ground push, which is conducive to horizontal displacement.

at the same time.

In the body vacant phase.

Proper contraction of the hip muscles can adjust the position of the lower limbs.

Maintain body balance.

Enable the body's center of gravity to move forward smoothly.

Be prepared for the next landing and striking.

If the hip muscles are insufficient or improperly controlled, it may cause excessive fluctuations in the center of gravity of the body, affecting the stability and efficiency of running, and reducing the effect of horizontal displacement.

There are individual differences in the structure, function and performance of the hip muscles of different athletes. These differences include the distribution of muscle fiber types, the level of muscle strength and explosiveness, neuromuscular control ability, etc.

Some athletes may have natural hip muscle structure and functional characteristics that are more suitable for sprinting, such as high proportion of fast muscle fibers, strong muscle strength and explosive power, etc. They can better exert the horizontal displacement of the hip muscles in 100-meter sprinting.

Just like Su Shen.

He is what he calls this - someone who may be born with the structure and functional characteristics of the hip muscles that are more suitable for sprinting.

Remember.

As an important link in this biomechanical chain, the buttock muscles work closely with the muscles and joints in other parts to achieve efficient horizontal displacement.

From the perspective of the lower limbs, the hip muscles work together with the quadriceps on the front of the thigh, the hamstrings on the back and the calf muscles. During the ground pushing stage, the gluteus maximus contracts and stretches the hips, while the quadriceps on the knees contract and stretches the knees, and the triceps on the calf contract and flex the ankle, forming a continuous power transmission process, transmitting strength from the hips to the feet and pushing the body forward.

From the perspective of the trunk, the buttocks muscles cooperate with the waist and abdomen to maintain body balance and stability. During running, the buttocks muscles provide stable support for the waist and abdominal muscles by fixing the pelvis, so that they can effectively participate in the body's rotation and swing, coordinate the movement of the upper and lower limbs, and improve overall exercise efficiency.

After seven steps.

Su Shen.

Start to speed up.

Helps to exert muscle elasticity and horizontal displacement.

Bang bang bang bang bang bang.

"Su's startup is too fast."

After the commentator finished speaking, the next picture was-

Sushen acceleration zone further demonstrates its power.

Ten meters.

The gluteus minimus is completely activated.

The gluteus minimus is located deep on the gluteus medius, which also originates from the outside of the ilium wing and ends at the femoral trochanter. It closely cooperates with the gluteus medius and is responsible for the abduction, internal rotation and stable work of the hip joint during running.

During the sprint, the gluteus minimus assists the gluteus medius to maintain the correct posture of the body on the horizontal plane.

Reduce ineffective energy loss.

Optimize the efficiency of horizontal displacement.

Enables athletes to control their body direction and balance more accurately when running.

If you can do the above, your horizontal displacement will naturally become stronger.

Another ten meters.

The gluteal medius is completely activated.

The gluteus medius is located deep in the gluteus maximus, which starts outside the ilium wing and ends at the femoral trochanter.

During the sprinting process, especially during the single-leg support period, the gluteus medius plays a key role.

It keeps the pelvis stable, prevents the pelvis from tilting to the opposite side, and ensures the body's balance in the horizontal direction.

In the 100-meter sprint high-speed running, the support of each step is inseparable from the stability of the gluteus medius, ensuring the stable movement of the body's center of gravity, and ensuring the smoothness and efficiency of horizontal displacement.

You can do the above well, and it will naturally be faster.

Bang bang bang bang bang bang.

Ten meters more.

Continue to accelerate.

The gluteus maximus is completely activated.

The gluteus maximus is the muscle with the largest and most superficial position in the hip. It starts outside the elixir wings and the back of the sacrum. The muscle fibers are thick and extend outward and lower in a fan-shaped shape, and ends at the glutes and iliotibial band.

This chapter is not over, please click on the next page to continue reading! The upper fiber contraction is mainly responsible for hip abduction, and the lower fibers dominate hip extension.

In the acceleration stage after the start of the 100-meter sprint, the athlete's rear pedal movement has a large amplitude and strong strength. The fibers in the lower gluteus maximus contract violently, stretching the hip joint with all its strength, producing a strong rear pedal force.

Push the body to move forward horizontally quickly.

Provides strong power support for acceleration after starting.

If these three muscle attributes are done well, your horizontal displacement will help you enter a higher state.

Your startup and acceleration.

It also entered a higher state.

So you heard the next sentence from the live commentator or—

"Su's acceleration is too fast!"

It's like changing only one word.

Switched from startup to acceleration.

It can be seen how much shock the acceleration here of Su Shen has caused.

Every time you think he has reached his limit.

He will tell you.

He hasn't.

Gradually, I looked up and ran on the way.
