Intuitive to terrible.

Why did Su Shen tell him that this is called deciphering one of the codes for sprinting mechanics?

It is because of this system that can accurately reconstruct the motion trajectory.

In sprinting, the athlete's movement trajectory is a complex three-dimensional spatial curve, involving the coordinated movement of various parts of the body.

The infrared three-dimensional capture system uses multiple infrared cameras to track reflective marking points pasted on key parts of the athlete's body from different perspectives, and uses the principle of triangulation to accurately calculate the three-dimensional coordinates of the marking points.

This chapter is not finished yet, please click on the next page to continue reading the exciting content later! Through these coordinate data, the system can reconstruct the athlete's bone position at every moment during the sprint with extremely high accuracy, generate continuous and detailed bone projections, and fully present the movement trajectory of key positions such as the body's center of gravity and joint nodes.

This accurate motion trajectory record at the millimeter level provides basic data for subsequent in-depth analysis of the kinematic characteristics of sprinting exercises.

Then do multi-dimensional motion parameters to obtain.

For example, joint angle and angular velocity.

Based on the constructed skeletal model, the system can calculate the angular changes of each joint in three-dimensional space in real time.

For example, during sprinting, the flexion and extension angles of the hip, knee and ankle joints and their changes over time are key indicators for measuring leg movement efficiency.

Through the infrared three-dimensional capture system, these parameters can be accurately obtained and the joint movement patterns at different stages can be analyzed, such as the rapid extension angle and angular velocity of the knee joint during the starting stage, providing a quantitative basis for evaluating the starting technology.

For example, linear velocity and acceleration.

In addition to joint motion parameters, the system can also calculate the linear velocity and acceleration of the center of mass in each part of the body. During the sprint acceleration stage, the acceleration of the center of gravity of the body and the changes in the linear velocity of the legs, arms and other parts directly reflect the athlete's explosive power and speed improvement ability.

Then, it is combined with the precise calculation of joint forces and torque of the system.

Joint forces and torque are important dynamic factors that affect sprint performance. The bone projection data generated by the infrared three-dimensional capture system, combined with human anatomy and mechanics principles, provide the possibility for the precise calculation of joint forces and torque.

Using the inverse dynamics method, the forces and torque generated by each joint during movement can be calculated through known kinematic parameters such as joint angle, angular velocity, angular acceleration and athlete's body mass distribution models.

It was impossible to calculate so clearly before.

There is this now.

It's possible.

Add accurate assessment of muscle strength and power.

Just like by analyzing the force arms and torque data of the calf triceps at the ankle joint and joint movement, the power output of the calf triceps during the pedal process can be calculated, thereby evaluating the effectiveness of the muscle group in sprinting, providing a basis for formulating a targeted muscle training plan.

Muscles are the source of motivation for producing movement, and accurate assessment of muscle strength and power is crucial to understanding sprint mechanics. Although the infrared three-dimensional capture system cannot directly measure muscle strength, the joint movement and stress situation reflected by bone projection, combined with the musculoskeletal model, can indirectly estimate the force magnitude and power output of different muscle groups during sprinting.

This will enable more accurate technical action diagnosis.

There is no perfection.

Only more perfect.

You feel perfect now because of your vision and cognition, that's it.

In sprinting, each stage such as starting, accelerating, running on the way and sprinting have specific technical and action requirements.

The bone projection generated by the infrared three-dimensional capture system can intuitively display the athlete's movement details at each stage, helping coaches and scientific researchers to conduct accurate technical movement diagnosis.

By comparing the standard action models of outstanding athletes and the skeletal projection data of athletes to be analyzed, we can quickly find technical problems such as incorrect starting posture, such as the body's center of gravity is too high or too low during running, the legs pushing angle is unreasonable, the arm swing and leg swinging are incoordinated when running on the way, such as insufficient amplitude or inconsistent frequency of the arm swinging, which provides a clear direction for subsequent technical improvements.

Until now.

You want to break through.

What is needed is solid basic theories and promote detailed data testing support.

Such situations like the situation where breakthroughs were completed with inspiration in the 1980s and 1990s are becoming increasingly unlikely to happen again.

If you want to go further on this basis, you not only need theoretical upgrades, but also need a future knowledge system as support, and avoid various wrong divisions, but also need more powerful black technology as an auxiliary.

This is why modern athletes do not have super talented people of the Five Tiger level again.

The reason why you can also achieve good results.

To be able to go further, it is necessary to develop in all aspects and provide all-round assistance, and perhaps it can break through 0.01.

With these.

Su Shen can say it.

I really have the conditions to continue to attack the next step.

If these productivity and technological levels cannot keep up, even a bunch of theories will be difficult to put into practice.

Not the best effect.

Now.

Only then can you say that the stage has been built for yourself.

You just need to take the stage to perform.

oh.

By the way.

As for why the plateau area is chosen as the test.

That's because the oxygen content in the plateau is low. When athletes conduct sprinting training in this environment, their bodies will adapt to the hypoxic environment by increasing red blood cell production and improving cardiopulmonary function to ensure aerobic metabolism and energy supply.

Using infrared three-dimensional capture system to analyze the sprint mechanics at this time can provide a deeper understanding of the athlete's aerobic capacity improvement mechanism and provide reference for formulating a plain training plan.

Comparing the mechanics data of sprinting before and after plateau training can clearly see the impact of improving aerobic capacity on the mechanics performance of each stage of sprinting.

Such as maintaining explosive power in the starting acceleration stage and the stability of the rhythm of running on the way, etc., it provides a quantitative basis for evaluating the impact of plateau training on aerobic ability and sprinting performance.

This can better study the special effects of muscle strength and nerve regulation.

How about it.

Now it is difficult to know why Su Shen said that high-level athletes can improve by 0.01 seconds.

Because what you want later is a lot of resources to support, and you can't do it easily by yourself.

To continue to make breakthroughs, without systems and plug-ins, you need various realistic mechanisms to assist yourself.

Su Shen has been waiting for this device to be debugged for a long time.

Finally, when I was having a peak showdown with Bolt this year.

Debugging successfully.

This also gave him continued breakthroughs, providing motivation and possibility.

So.

Usain.

I said to catch up with your world record.

You'll know soon.

I'm not kidding.

My past 10 years.

From the knowledge system to the own efforts in science and technology and the overall environment creation...

But I didn't dare to stop for a moment.

Now.

It should be for you to see ten years of hard work.

When this piece is not sharp.

Let yourself see it.

I have been able to sharpen my sword in the past ten years.

Is it sufficient to hit the top number?

It was at this time.

The password to the game sounded.

“Each is in place.”

"preparation."
