"It's so bad! It's so bad! How many detours have you taken!!!"

Below are "throwing" one by one, which shows that even these elite athletes of the domestic sprinting era are all "victims" in this regard. Not only is it wasted time in vain, but it was also the wrong direction to work hard.

"Of course, this can also be used to better optimize the stride frequency." Su Shen continued: "Because the back swing and the front swing of the circular swing arm form a closed circular shape, it is equivalent to effectively solving the pause problem when the front and back high points during swing arm movement. Solving this pause problem naturally means speeding up the swing frequency of the swing arm, thereby optimizing and improving the stride frequency."

"At the same time, because the circular swing arm has the best swing inertia, it is equivalent to applying the movement inertia. In addition, the swing direction is also required to be consistent with the running direction. In this way, the penetration force generated during the swing arm will not produce a force-partition effect. This has a very positive promotion significance for increasing speed, saving physical energy, and better using the biomechanical properties of the swing arm."

"However, although this round arm swinging action is easy to use and has many advantages, there are also problems that cannot be ignored." Su Shen said: "Everyone must remember this problem clearly to avoid irreversible injuries during training, affecting grades and training."

Su Shen drew a structural diagram near the shoulder joint on the small blackboard and said: "Because this technology has a large load on the shoulders, the overall need to use the shoulders as the axis, so it may require more functions than simply using the shoulders to exert force. In this way, the project we must do at the same time in our daily training is——————”

"The relaxation, stretching and traction of muscles near the shoulders, as well as the improvement of shoulder flexibility, the improvement of shoulder support, and the improvement of shoulder strength. This part of the shoulder is also called the "core part" of the upper body. If this place is injured, you may not be able to do any movements in the upper body."

"So, I have a set of shoulder training, improvement, resistance, flexibility and other training here. I will send it to you later. Everyone should remember to intersperse it in daily training, improve it bit by bit, lay the foundation for the subsequent technical improvements and prepare."

After Su Shen finished speaking, he put down the chalk, looked up at the elite domestic athletes who had "studyed" below, and asked-

"Did you understand everything? If you don't learn it, you can ask it again. I will give you some details about what you don't understand."

The following ones are all feeling that your brain is hollowed out.

For them, it is not easy to accept such profound theoretical knowledge learning.

It’s not that they have any problems with learning ability and IQ, but they don’t have the habit of learning theory in normal times, so when they suddenly learn, they become so profound, they will naturally be a little "not adapted".

What is Su Shen’s method for this situation?

Not very adaptable, not very used to it, right?

Hehe, yes.

Then learn more, memorize more, test more, learn how you adapt and learn how you are used to, isn’t that enough?

Everyone:...

"By the way, it's the same. I memorize it in a short time, and then I check it one by one. If you can't memorize it, don't learn this new technology. Let's talk about it after memorizing it."

Ahhhhhhhh!

Oh my God, the earth, please let Teacher Su be a person.

We really hate "endorsement".

"I hate to be memorized, right? So do you want to write another thousand-word reading review?"

When everyone heard that Su Shen’s idea was so "Russian", he would quickly choose the former.

Just kidding, just memorize and write, it’s really not something that people do.

But they didn't know that after this period of polishing, their sports science concepts and sports-related knowledge have been subtly surpassed the rest of the domestic athletes.

If you want to improve, you must endorse it first.

It has also become one of the most talked about in the era of "Su Shen Clan".

The outside world's familiarity is comparable to the century's question - "What size is Su Shen's butt?"

Tie to be first.

PS: Every time I write about technical improvement, I will be bald, hahahaha, I laugh and cry.

It is really difficult to summarize the differences between traditional systems and the latest technologies. Xiao Zi is so bald. Come and comfort Xiao Zi's injured and young mind.
