The upper limbs of the human body are a motor chain composed of multiple joints and muscles. During the start of the bent arm, the shoulder joint, elbow joint and wrist joint work together. The force generated by the contraction of the deltoid anterior bundle is transmitted along the forearm to the palm of the hand through the locked elbow joint. Because the triceps maintain the stability of the elbow joint, the force is less lost during the transmission process, and can be transmitted from the shoulder joint to the palm more efficiently, and then act on the ground.

This chapter is not over, please click on the next page to continue reading! Then when the shoulder joint dynamic arm is extended, the force generated by the contraction of the deltoid anterior bundle is transmitted to the palm through the longer power arm, so that the palm can act on the ground with greater force and more reasonable angles, thereby obtaining greater ground reaction force and pushing the body forward.

This involves the integration of upper limb motion chains and their relationship with ground reaction forces.

If you can't imagine that only knowledge embedding here, you will never be able to touch this trick, let alone understand the training mode and system.

How many scientific teams can achieve theories that can be combined?

Now here in Su Shen.

Raise your hand to break.

Easy integration.

This is the true strength of the science flow reopener.

He knows all the right paths, he knows all the wrong lightning protection.

He can integrate it alone, and requires many scientific teams in different systems to comprehensively cross-verify theories.

Su Shen looked like he had no gold fingers or plug-ins to reopen.

But in fact.

A person with real knowledge and knowledge reserves.

Straight across.

The knowledge system structure for so many years.

Always have the right cognitive direction.

It's the biggest hanging.

The 110° curved arm technique used by Su Shen here transfers the fulcrum to the elbow joint.

It is to form a...compound leverage system!

During the contraction of the deltoid anterior muscle, the chemical energy stored by the muscle is converted into mechanical energy. By extending the power arm, the mechanical energy generated by the contraction of the muscle can be transmitted more effectively to the overall movement of the body.

The extension of the power arm is equivalent to increasing the action distance of the force. According to the principle of work W = Fs (work = force x distance), when the force is certain, the action distance increases and the work done by the force increases, so that the body can obtain greater kinetic energy and increase the starting speed.

This involves muscle energy and transformation.

Then, remodel the pretension conduction path of 100 meters.

Reconstruct the composition of the "abdominal pressure cylinder" mechanism.

The transverse abdominal muscle is the deepest muscle in the abdominal wall, and its muscle fibers surround the abdomen. When the transverse abdominal muscle contracts, it will apply pressure to the contents of the abdominal cavity from the deep layer of the abdomen like a bulb. It is an important part of the "abdominal pressure cylinder" mechanism, which can stabilize the abdominal cavity and provide a stable foundation for other movements.

The polyfis muscle is located on both sides of the spine and consists of multiple muscle bundles, extending from the sacrum to the cervical spine. Its main function is to assist the extension, lateral flexion and rotation of the spine, and to perform fine stabilization control of the spine segments. In the "abdominal pressure cylinder" mechanism, the polyfis muscle contraction can enhance the support and stabilization effect on the spine from the back, cooperate with the transverse abdominal muscles, and maintain the integrity of the "abdominal pressure cylinder" from the front and back directions.

When the transverse abdominal muscles and the multifissure muscles contract at the same time, they compress the organs in the abdominal cavity, causing the pressure in the abdominal cavity to increase. This increased abdominal pressure is like forming a pressure-filled "cylinder" in the abdominal cavity, providing additional rigid support for the trunk.

This rigidity allows the trunk to better maintain its shape and stability when subjected to external forces, and reduce unnecessary deformation and energy loss.

The pressure generated by the "abdominal pressure cylinder" is evenly distributed in the abdominal cavity and is transmitted to the entire trunk through the muscle fascia structure of the abdomen and back. In this way, the force generated by the extension of the lower limbs can be transmitted upward more effectively along this rigid trunk without dispersing or shifting the force due to the softness or instability of the trunk.

This uses the transverse abdominal muscles and polyfiss muscles to produce, maintain pressure and disperse and transmit force.

This is equivalent to letting-

The curved arm state causes the brachioradialis muscle, the superficial flexor muscle, etc. to form a prestressed bundle, which directly transmits the forward stretching force of the scapula to the starting device, reducing the dispersion and transmission of energy losses and force.

Cooperate with your local talent in back muscles.

Combined.

Then the upper limb stiffness is re-adjusted.

It's done.

But sprinting is more athletes with lower limbs.

No matter how well your upper limbs are done, you can't move.

Then, we come to the second question - using the coupling of core muscle groups to reconstruct the deep logic of axial conduction of the lower limb pedal stretching force.

That is, after doing the above.

At the start, the use of lower limb stretching force needs to be transmitted through the torso to the upper limbs and the whole body to push the body forward.

The trunk rigidity established by the "abdominal pressure cylinder" mechanism makes the conduction path of force more direct and smooth, reducing the loss and direction changes of force during the conduction process.

The use of the lower limb pedal stretching force can conduct upwards more efficiently along the central axis of the body, providing powerful power support for the rapid start of the body.

At the same time, the transverse abdominal muscle and multifissure muscle work together with other core muscle groups such as rectus abdominal muscle, oblique abdominal muscle, etc. to maintain the overall stability of the body.

When the lower limbs are stretched, these muscles cooperate with each other to stabilize the trunk through the "abdominal pressure cylinder" mechanism, ensuring that the body maintains the correct posture and balance during the starting process, so that the lower limbs' stretching force can be completely converted into the body's forward acceleration, and improve the efficiency and speed of the starting.

With the help of in addition to transverse abdominal muscle and polyfiss muscle, rectus abdominal muscle, oblique abdominal muscle, etc., the contraction of rectus abdominal muscle can increase the pressure on the anterior side of the abdominal muscle. The oblique abdominal muscle can assist in the generation of rotation and lateral flexion forces, and work together with transverse abdominal muscle and polyfiss muscle.

Stabilize the trunk from multiple directions, make the "abdominal pressure cylinder" more stable, and provide a solid foundation for the transmission of the lower limb pedal stretching force.

The muscles then connect to each other through the fascia to form myofascial chains.

In the "abdominal pressure cylinder" mechanism, the transverse abdominal muscles and multifissure muscles are connected to the fascia of the surrounding muscles, forming a force transmission network.

The lower limb stretching force can be transmitted to the core muscle group through the fascia, and then the fascia of the core muscle group transmits the force upward to the upper limbs and other parts, realizing the integration and transmission of whole body strength.

In this case.

Originally, the bent arm starts at 1.0, but the trunk lacks rigidity. The force of the lower limbs will cause unnecessary movements such as bending and twisting, resulting in dispersion and loss of force, etc.

They will be improved.

Su Shen’s curved arm starts 2.0, which uses the rigid torso established by the “abdominal pressure cylinder” mechanism, can cause the lower limb stretching force to conduct upward along the central axis of the body, reduce the loss of force during the transmission process, improve energy utilization efficiency, and make more energy use to push the body forward and accelerate.

So……

Want to be unhappy.

All are difficult.

Su Shen step by step.

It's exactly the same thing he does every game every season after he reopens.

He has done this for the past 10 years.

Every game has obvious purpose.

Each game has obvious mission goals and experimental subjects.

Whether it is success or not.

The goal is extremely clear.

Never waste any game.

After all, these competitions were carefully selected through his memory.

Every game has its considerations for every game.

It must not be wasted easily.

Bang!

this.

That is why Su Shen saw Carter and Bolt.

Their activations are all strengthened.

They have further broken through their limits.

But it is still as stable as Mount Tai.

It's like Jiang Taigong fishing.

Sitting there motionless.

The reason why they are not affected at all.

Because.

To apply that famous quote from the noble young man in the mall—

Usually when I start it.

I don't care whether the other party starts quickly or not.

I don't care whether the other party's activation has a breakthrough.
