Small goals, first to be the world's first [Competition]

Back then when candy bars were prevalent, Su Haizhong and Xu Yuanwei were called twin stars when they were young. They were invincible in doubles, and their configuration was also the best configuration of a left hand and a right hand.

Xu Yuanwei is right-handed and penhold-holding, which is exactly the same as Zhong Yu. This is one of the important reasons why Su Hai brought Zhong Yu to Xu Yuanwei.

After registering at the security office at the gate, Xu Yuanwei led them to a, um...a very technological building.

Su Yuan's first reaction was that this building was somewhat similar to the building in the newly built large base when he participated in variety shows in Province S.

What Xu Yuanwei said next confirmed his conjecture.

Xu Yuanwei took out his pocket, took out an ID card, and pasted it on the credit card machine next to the entrance of the high-rise building. With a sound of "beep--", the glass door slowly opened, and a burst of gratifying cold air from the air conditioner The building blew out.

Xu Yuanwei put the card back into his pocket, smiled and waved at them, motioning for the three of them to follow him in.

"You should know the K building in the new base in province S. I know that your variety show was recorded there. I don't know if you have ever entered that building." Xu Yuanwei said as he led them to the elevator.

"No. The program team told us that the things in that building are more expensive, so try not to go if you can." Su Yuan and Zhong Yu shook their heads at the same time.

Xu Yuanwei nodded thoughtfully, and pressed the down button of the elevator with his slender fingers. After everyone entered the elevator, he pressed the button for the tenth floor, retracted his hand and spoke again.

"Well...then let me introduce this building a little bit."

On the walls on both sides of the elevator, there are approximate distribution maps of the entire building. Xu Yuanwei pointed to those distribution maps and introduced them gently.

"The existence of the K building is to better combine athletes' training with technology to achieve scientific training and further goals. However, the cost of the building and related equipment is too high, and the concept is more advanced. Many places are still waiting to see. Now except Only our province j has finished building the new base in province s."

Xu Yuanwei said quite proudly.

Not to be outdone, Su Haizhong hummed softly, and interjected: "Our province has already approved it, and it's under construction!"

……childish.

Xu Yuanwei rolled his eyes at him lightly, and no longer cared about this daily nonsense, the long paragraph just now, this person probably only heard that only province S and province J in this building have made comparisons heart of.

The other implied meanings were all in vain to him, Xu Yuanwei glanced at Zhong Yu who was pensive because of the words just now, and nodded in satisfaction in his heart.

It seems that Su Haizhong has finally accepted an apprentice who is not a single mind.

He smiled and continued.

"This building has only been completed recently, and the facilities inside have not yet been fully equipped, but several key equipment have been transported back from abroad with great effort."

"The focus is on a few ball machines and the recording and analysis equipment that matches the ball machines. Because the equipment is relatively large and expensive, it was not placed in the training hall, but was taken out and placed in this building."

"It's here, it's on this floor, come with me."

The elevator stopped on the tenth floor, and the door opened slowly. Xu Yuanwei squinted his eyes and walked out first.

Swiping the card again to open the door of a room, Su Yuan followed Xu Yuanwei into it, and couldn't help but let out an exclamation.

Different from the smaller ball machines that are commonly used in the market or in athlete training, where several ball machines can be placed in one room, the one that enters the door is a table tennis table and the silver-white one opposite the table occupies the entire wall. of large equipment.

The volume of the main body of the ball machine is still not large, what is more, is the dazzling screen with the colorful code floating beside it.

There is a huge mainframe in the corner, connected to several LCD screens hanging on the wall, one of which is still playing the video of Zhongyu’s semi-final match, even slowing down and automatically pausing, the display next to it On the screen, data and action analysis are constantly popping up.

... Zhong Yu also saw his figure in the video, the corners of his mouth twitched involuntarily, and his knees ached.

A misstep becomes an eternal hate.

He felt that he would inevitably have to explain and apologize again. The cost of making a mistake was too high, and Zhong Yu would never dare again.

Xu Yuanwei took out some small discs from above the main unit in the corner and walked over. Seeing their eyes on the video that was playing in a loop next to them, he raised his eyebrows, walked to them and explained with a smile.

"This is automatic analysis and slow motion to capture your performance and movement completion in this game, Zhong Yu, can you roll up your sleeves a little?"

Zhong Yu was slightly taken aback when he heard the words, but he still unbuttoned the cuffs of his shirt and rolled them up a little.

Xu Yuanwei rubbed his chin, he seemed dissatisfied, he took a look at Zhong Yu, and said directly: "Forget it, just take off your shirt."

?

Zhong Yu opened his eyes slightly, and from the corner of his eyes, he unconsciously wanted to glance at Su Yuan who was standing beside him, pursed his lips, and froze in place.

Xu Yuanwei raised his eyebrows, "Shy?"

"Don't be afraid, this is a bio-sensing soft patch, which is attached to specific places on your wrist and shoulder. It can monitor your real-time physical condition, capture and transmit your movement data in real time, and form a database exclusive to you for later analysis. and formulate specific plans.”

"The domestic technology and procedures can't keep up. It was bought from Germany at a high price. It just arrived not long ago and hasn't been officially used yet. Take it off quickly and put it on after it's pasted."

Xu Yuanwei patted Zhong Yu's shoulder and said with a smile.

Su Yuan was also stunned when he heard the words, and curiously stepped forward to touch the slightly bulky host. For some reason, after listening to Uncle Xu's description, he always felt that the function of this device was similar to the system his master gave him.

Taking advantage of the time when Xu Yuanwei put the sensor chip on Zhong Yu, Su Yuan also leaned over, touched Zhong Yu's abdominal muscles unconsciously, and at the same time opened up in his mind the data analysis module.

He wanted to see if the results of the two analyzes would be the same.

Zhong Yu lowered his eyes to look at his eight-pack abs that had been wiped with oil, and looked at Yuan Bao with a bit of resentment.

The child unconsciously stoked the fire but was not responsible for putting it out. He took a deep breath, closed his eyes, and suppressed the eager flame in his heart.

Not yet, it's too early.

"Five sets of forehand and backhand alternately, two sets of pulling the ball, and two sets of cutting the ball. By the way, this table is also specially made. Later, we will divide the landing area on the opposite table, and each ball will change. The high area shrinks, and you not only have to hit the ball back, but you have to hit the ball as far as possible in the area where it was marked."

After setting the parameters of the ball machine, Xu Yuanwei raised his hand and glanced at his watch, nodded to Zhong Yu and said, at the same time he reached out his hand expressionlessly to stop Su Haizhong who was close to him and wanted to do something to the ball machine.

"Don't make trouble, finish the test for your apprentice first." Xu Yuanwei warned Su Hai with a dark face.

"Haven't I seen such a high-tech..." Su Haizhong whispered a little aggrieved, but still put his hands aside and stood aside, and then tried to put on a dignified look to look at Su Yuan and Zhong Yu.

Stop pretending, his sand sculpture father, Su Yuan couldn't bear to look straight at him, and turned his attention to Zhong Yu.

"Drip - the connection is complete, the first group: forehand fixed-point attack."

The emotionless inorganic electronic female voice sounded, marking the beginning of this test.

In the next moment, the black ball machine spit out white balls one after another extremely swiftly.

This spin and speed!

Those ball machines that are commonly seen in peace are not at the same level at all!

The serving machine that Su Yuan came into contact with during training in the national team was still a relatively rigid one, and he could only set up a rotating and relatively old-fashioned serving machine. There is no great training value, so the national team still basically adopts the artificial serve training method.

There are also disadvantages of artificial serving. First, there are not many coaches who can feed the ball well. Second, it is difficult to achieve the high-speed connection of the serving machine, so the efficiency is not very high.

But now the popular domestic ball machine rotation and ball path changes are too simple, basically only used for the basic connection and physical connection of the players. For more professional special training, it can only be done manually.

The coaches who can feed the ball well are also one in a hundred, so there has always been a problem of uneven levels in domestic training.

Perhaps Su Yuan and Zhong Yu are not clear enough about this question, but how could Su Haizhong, who is the head coach of the national team, not be clear.

Their national team has not recruited good seedlings for many years, which is one of the reasons.

This is a vicious circle, without good coaches, without good equipment, and poor grassroots training, let alone a good seed suddenly appearing in the annual selection of the national team.

Therefore, starting a few years ago, Su Haizhong's work focus has been shifted from the training of the national team, and the main affairs have been handed over to the head coach of the men's and women's teams. Sports school inspections, personal guidance and suggestions, and some small reforms.

Although it doesn't seem to have much effect so far, it will always play a role. Su Haizhong is extremely firm.

At this time, he even saw new hope. Such a serving machine may be a breakthrough to solve the problem of grassroots training!

From Zhong Yu's return and pace adjustment, we can see how high the quality of the balls produced by this server machine is. Even if we observe the tightly connected white balls with the naked eye, we can see the intense force. spin and ball speed.

And just in the past few minutes, Su Haizhong has seen several kinds of spins, topspin, backspin, measured topspin... Although it is not as good as the spins played by top players, it is more than enough for daily training!

"Old Xu, regardless of other equipment, how much is the ball machine alone?" Su Hai pestered Xu Yuanwei next to him, and asked expectantly.

In a word, Xu Yuanwei understood what Su Haizhong was thinking. He also thought about this question, but...he glanced at the black ball machine next to him, and replied with a wry smile: "It's just a ball machine. Fifty to sixty thousand, um... US dollars."

Su Hai's heavy face instantly collapsed, and Su Yuan's eyes widened in shock when he heard the price.

Although these devices look really high-tech... But Su Yuan never expected that the price of a ball machine is so shocking, the whole set...?

can not imagine.

He looked at Zhong Yu, who was about to finish several sets of training, and the analysis of Zhong Yu's movements by the data analysis module was still flashing in front of his eyes, and the blue numbers kept jumping on the light curtain in front of him.

Then his gaze turned to the huge LCD screen hanging next to it, which was constantly refreshing, the capture and analysis of Zhong Yu's movements by this giant device.

Su Yuan narrowed his eyes, and a bold idea emerged in his heart.

The author has something to say:

I did a search and boldly ranked them in descending order of price! (That is to say, an option that I didn’t dare to look at at all before) Then I found the highest price of the domestic ball machine, which is about [-] to [-] yuan. Pupil earthquake.jpg

The pa settings in this article basically belong to me!Overhead!
