Back in Xiangshan City, the training still has to continue.

There is the next Grand Prix at the end of this month.

Moreover, you say that it is not a coincidence, it happens to be held in Xiangshan City.

Therefore, everyone is fighting at home.

However, this is the last battle of the Grand Prix, and the competition is still fierce, at least much more fierce than the previous round.

It is said that a bunch of bigwigs will come over.

At that time, except for Zhao Haohuan, I am afraid that Su Shen would not have any chances.

Now the fastest in China is indeed only 10.20+ level, but there are still many people in the 10.20-10.50 section.

It's just that the domestic training system is not systematic enough, resulting in many people's state fluctuating greatly and not stable at all.

However, since it was to prepare for the National Games, Su Shen did not feel that he would have no chance at all, after all, the "curved arm starting technique" that he had just started was still far behind. It's just that it's just been used on the horse, and it's far from being run in to the level of proficiency of the body, so it's just a good time to strengthen it.

There is also the "six-second rule", this technical action, Su Shen feels that it can be upgraded.

It is also a technique that requires changes in the upper limbs to improve.

Zhou Bing and Zhao Haohuan's upper body strength is not up to standard, but when they can barely bend their arms to start, Su Shen's upgraded skills in this area can be used and start to join the training course.

It's also just a good example for the big guys.

That is the integration of the "Stretch Palm Swing Arm Technique".

The general direction of the technique of sprinting has also passed through the stepping, stride, and swinging type.

But in fact, after the swing type, the era that is about to enter, not to mention for the time being, the new technology that Su Shen is going to join now is mainly in terms of swinging arms. At the beginning of the 21st century, the research of swinging arm technology in China was still quite backward, such as the palm posture of swinging the arm, or the traditional half-clenched fist swinging arm style.

This swingarm technique, well, really Soviet Big Brother.

Maybe there were times when it was advanced in the past, but now that the times have changed, continuing to use this set will have a great impact.

For example, before Su Shen himself reopened, most of the time, he had been adopting this way of swinging his arms, and even because the training time was too long, he was not able to modify it well. Of course, it may also be a half-fist grip, which is more suitable for athletes with a slightly shorter stature, and the research on this aspect is not in-depth. But one thing is for sure, the palms are wide open and the running style of the vast majority of top athletes.

Su Shen has been using this since he reopened, and that's because his height has not yet broken through a boundary. After coming back, I deliberately measured it, and now my height has reached 178.7. In this way, it seems that it is possible to exceed 179 in the future, and even reach 180. In that case, you can try to change the half-grip posture of the swing arm.

Don't think it's nonsense, it's based on science.

Through experimental analysis, the swing arm frequency of the half-clenched fist is lagging behind the swing arm frequency of the extended palm.

The specific data is 10 seconds or something, and there is a difference of about 2.5 times.

Let's calculate the principle of the human body's bone bar lever - resistance = force X force arm / resistance arm.

According to the formula, there are only two best ways to overcome air resistance during running.

One is to increase the force arm and the other is to shorten the resistance arm.

Because the longer the arm, the less power is needed to overcome resistance, then pushing down according to this law of physics can easily conclude that extending a finger will lengthen the condition of the arm.

The force arm is larger than the resistance arm.

Naturally, it will be relatively labor-saving.

The most important thing is that this change of movement, far from slowing down your swing arm frequency, has been proven to speed up.

And when the fingers are extended, the distance between the forearms increases, and the advantage of this increase is that the swing arm can be pulled through the palm.

This increases the speed and power of the swing arm, and the upper arm and forearm can be better combined by traction.

So why did both the country and the USSR like to take a half-grip swingarm?

Because the half-grip type will produce a relatively relaxed feeling during running.

It looks more in line with the law of the human arm swing.

However, experiments have proved that running in this way is weaker than stretching the palm swinging arm in terms of both the frequency of the swing arm and the speed and strength of the swing arm.

And it cannot create a traction effect in the palm of the hand.

This is also obvious in ordinary people, and generally speaking, it can directly increase the speed by about 0.4~0.7 seconds. (You can give it a try quickly, improve instantly, a must-have for lazy bags).

If it is further extended to anatomy, it is even more obvious that there is a rule.

That is, the strength of the flexor muscles of the upper limbs of the human body is generally greater than that of the extensor muscles.

And the finger arm, which opens the palm, is obviously to increase the participation of the extensor muscle group.

At the same time, it can also help the flexor muscles to stretch and loosen the joints around the shoulders more, thereby increasing the amplitude and strength of the swing arm during sprinting.

Therefore, under a series of scientific theories, it is more appropriate to open the palm than the traditional half-grip.

Especially now that I've grown taller, the half-grip swing arm may be more suitable for a slightly shorter athlete, and the only possible advantage is gone.

Then you can put this technical modification on the agenda.

After all, 178.7 is not too short.

Now that I think about it, what I had in my head was really ...... It's an endless treasure.

When I was running, my mind was blank, I didn't know anything, I didn't understand anything.

In vain, the golden period and golden age were delayed.

Including the stability of technology, too much time was wasted, and I didn't follow the development of my body and make changes together.

Now, you can modify this aspect in advance.

However, this swingarm is different from the curved arm start.

The swing arm runs through the entire 100 meters, and a little modification is actually a whole body.

In the beginning, you will definitely experience discomfort, and it is normal for grades to decline.

But what are you afraid of now?

Yourself now.

I just have time.

I looked at my five-dimensional attributes——

Name: Su Shen.

HEIGHT: 178.7CM.

WEIGHT: 72.9KG.

Strength: 42.

Speed: 47.

Endurance: 43.

Reactions: 43.

Plicity: 41.

Nearly 100,000 "five-dimensional points" have been invested in endurance potential and flexibility potential, and only then has such a small amount been added.

It looks like there's a long way to go.

It also takes a lot of training to realize these potentials.

But......

Being able to see the detailed data of your body is actually a good advantage, and you can keep track of the dynamics at all times, and there will be no difference at all.

After Su Shen took a shower, he went to bed early, striving to make this technical move early before the next competition and build muscle memory.

Combine experiential memory and muscle memory quickly.

Fortunately, I still have experience and memory, so I can save a lot of time in this area than ordinary people training from scratch.

And this technology can be fused into the "six-second burst", making the entire technical action more explosive.

As long as there is a way, the results of 10.30+10.40+, seriously......

This is what will not be on the table in a few decades.

I can't get into the finals of the National Games.

Su Shen went through the palm swing technique in his mind a few times in his mind, and then closed his eyes and went to sleep, preparing for tomorrow's new training.

PS: I'm sorry, as long as I check the information and the chapters of the paper, it will always be much slower, and please be considerate.

So,Actually, it's easier to write a pure system article.,This kung fu can be at least two chapters.,Woo woo~~~~.
