Back in Xiangshan City, training still has to continue.
There will be the next Grand Prix at the end of this month.
Moreover, you said it was a coincidence that it happened to be held in Xiangshan City.
So we are playing at home.
However, this is the final battle of the Grand Prix, and the competition is still very fierce, at least it is much more fierce than the previous round.
It is said that a lot of big guys will come over.
At that time, apart from Zhao Haohuan, Su Shen probably had no chance.
The fastest speed in China is indeed only 10.20+, but there are still many people in the 10.20-10.50 period.
It’s just that domestic training is not systematic enough, which causes many people’s status to fluctuate greatly and is not stable at all.
However, since he was preparing for the National Games, Su Shen did not feel that he would have no chance at all. After all, the "bent-arm starting technique" he had just mastered was still far from enough. It's just that I have just started using it, and it is far from being used to the level of physical proficiency. This period of time is just the right time to strengthen it.
There is also the "six-second rule", this technical move, Su Shen feels that it can be upgraded.
It is also a technical method that requires upper body changes to improve.
Zhou Bing and Zhao Haohuan's upper body strength is still not up to standard, but when they can barely load the bent arm to start, Su Shen's upgraded skills in this area can be used and they can start participating in training courses.
Just in time to give everyone a try.
That is the integration of the "palm extension and arm swinging technology".
The general technical direction of sprinting has also passed through the stepping style, stepping style, and entered the swing style.
But in fact, after the swing type, we are about to enter an era. Let’s not talk about this for now. The new technology that Su Shen is going to add now is mainly in the aspect of swing arms. The research on arm swing technology was still quite backward in our country at the beginning of the 21st century. For example, the palm posture of arm swing was still the traditional half-clenched fist arm swing.
This arm-swinging technique, well, is really like the big brother of the Soviet Union.
Maybe there were times when it was advanced before, but times have changed now. If we continue to use this method, the impact will be great.
For example, before Su Shen himself restarted, he had been using this arm swing method most of the time. He even failed to modify it properly because the training time was too long. Of course, it is also possible that the half-fist grip is more suitable for athletes who are slightly shorter in stature. There is research in this area, but it is not in-depth. But one thing is for sure, palms fully open is the running method of most top athletes.
Su Shen has been using this since he reopened. That's because his height hasn't broken through a limit yet. After I came back, I measured myself and found that my height is now 178.7cm. It seems that it is possible to exceed 179 or even reach 180 in the future. That way, you can try changing the half-grip posture of your arm.
Don't think this is nonsense, there is scientific basis for this.
Through experimental analysis, the arm swing frequency of the half-clenched fist lags behind the arm swing frequency of the extended palm.
The specific data is something like 10 seconds, and there is about a difference of 2.5 times.
Let's calculate the bone lever principle of the human body - resistance = force X moment arm/resistance arm.
According to the formula, if you want to overcome air resistance during running, there are only two methods that are most suitable.
One is to increase the strength arm and the other is to shorten the resistance arm.
Because the longer the moment arm, the less power is required to overcome the resistance. According to this physical law, by pushing down, you can easily derive the condition that extending your finger will extend the moment arm.
The moment arm is greater than the resistance arm.
Naturally it will be relatively effortless.
The most important thing is that such a change in movement will not slow down your arm swing frequency, and it has been proven that it can also speed up.
Moreover, when the fingers are extended, the distance between the forearms will increase. The advantage of this increase is that it allows the arm swing to produce a traction effect through the palm of the hand.
This can increase the speed and power of the arm swing, and the upper arm and forearm can be better combined through traction.
So why do both China and the Soviet Union like to adopt a half-grip arm swing?
Because the half-grip style will produce a relatively relaxed feeling during running.
It seems to be more in line with the human body's arm swing rules.
However, experiments have shown that when running like this, both the arm swing frequency and the speed and force of the arm swing are weaker than the arm swing with the extended palm.
And it cannot produce the traction effect of the palm.
This is equally obvious when used among ordinary people. Generally speaking, it can directly increase the speed by about 0.4 to 0.7 seconds. (You can give it a try quickly and it will improve instantly. It is a must-have for lazy people).
If you extend it further to anatomy, you can find a rule.
That is, the strength of the human body's upper limb flexor muscles is generally greater than that of the extensor muscles.
And fingering the arms and opening the palms obviously increases the participation of the extensor muscles.
At the same time, it can help stretch the flexor muscles and relax the joints around the shoulders, thereby increasing the range and strength of the arm swing during sprinting.
Therefore, according to a series of scientific theoretical systems, open palms are more appropriate than the traditional half-grip.
Especially now that I have grown taller, the half-grip swing may be more suitable for shorter athletes. This only possible advantage no longer exists.
Then you can put this technical modification on your agenda.
After all, 178.7 is not short by any means.
Looking back now, the things in my mind are really... endless treasures.
When I ran away, my mind was completely blank. I knew nothing and understood nothing.
The golden improvement period and golden age have been wasted in vain.
Including the stabilization of technique, too much time was wasted, and changes were not made along with the development of the body.
Now, I can modify this aspect in advance.
But this swing-arm start is different from the crank-arm start.
The arm swing runs throughout the entire 100 meters. A little modification is actually a movement of the whole body.
At the beginning, you will definitely experience discomfort and a decline in performance, which is normal.
But what am I afraid of now?
myself now.
I just have time.
Checked his five-dimensional attributes——
Name: Su Shen.
Height: 178.7CM.
Weight: 72.9KG.
Strength: 42.
Speed: 47.
Stamina: 43.
Reactions: 43.
Flexibility: 41.
Nearly 100,000 "five-dimensional points" were invested in endurance potential and flexibility potential, and the result was just this little increase.
It seems that the future really has 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. You can keep track of the dynamics at any time without any differences at all.
After Su Shen took a shower, he went to bed early to rest, trying to practice this technique as early as possible to build muscle memory before the next competition.
Let experience memory and muscle memory be combined quickly.
Fortunately, I still have experience and memory, so I can save a lot of time in this regard than ordinary people training from scratch.
Moreover, this technology can be integrated into the "six-second burst" to make the entire technical action more explosive.
As long as there is a way, a score of 10.30+10.40+, to be honest...
This is a result that will not be on the table decades later.
Can't even make it to the National Games finals.
Su Shen went through the technique of stretching and swinging his arms several times in his mind, then closed his eyes and went to sleep to prepare for tomorrow's new training.
PS: Sorry, as long as I look up information and chapters of papers, it will always be much slower. Please be considerate.
So, in fact, it is easier to write a purely systematic article. With this effort, it can take at least two chapters, woohoo~~~~
