"Don't stop, keep going, there are five more!" Dai Li's urging voice sounded.
On the training ground, Wang Anshan stood in front of the air resistance tensioner, constantly doing cross-tension exercises with his arms.
The air resistance tensioner is a relatively advanced training equipment. Its biggest feature is that it can adjust the exercise load more accurately. Traditional training equipment uses gravity counterweights. In layman's terms, it means adding weight-bearing iron plates. For example, in fitness equipment in European and American countries, the weight of a weight-bearing iron plate is generally 10 pounds. There are rarely 5 pounds of weight. The minimum weight is 5 pounds. It can only go to 2.5 pounds. In other words, the minimum weight increase during training is 2.5 pounds.
As for air resistance training equipment, the most common ones can also change the weight in units of 1 pound. Top sports equipment brands, such as KEISER's air resistance training equipment, can adjust the weight in units of 0.1 pounds, which is obviously more suitable for professional use. Precision training for athletes.
In addition, the air resistance training equipment can also adjust the weight separately. For example, when doing weight-bearing training on both arms, the weight-bearing strength of the two arms can be different. This can have a better training effect for sports such as table tennis and badminton where the force on the arms is uneven.
Wang Anshan gritted his teeth and exerted all his strength. Judging from his expression, the training load was very heavy, and Wang Anshan had almost reached the limit of his body.
But he still persisted. Although every movement he made was extremely difficult, he did not give up.
"Come on, there are four more! Grit your teeth and persist! Persistence is victory!" Li Dai still encouraged from the side.
Not far away, Gu Zhizhong and Wang Bin stood side by side, both of them watching this scene intently.
Training close to the physical limit can be regarded as a painful torture for athletes, and athletes will inevitably resist such training psychologically. Dai Li is not a top coach in the world, but he can make a top athlete in the world accept such extreme intensity training in such a cooperative manner. This can already explain Dai Li's success.
"In just a few days, he defeated Wang Anshan. We all underestimated him." Wang Bin said.
Gu Zhizhong nodded: "Yeah, I didn't expect it. I originally thought it would take a year and a half until he and the athletes are familiar with each other, and then the training will go on smoothly. But now it's not Within a week, Wang Anshan was willing to train so hard, which was really beyond my expectation. But this is just right, it shows that he is capable, and I can safely leave Zuo Xiangxian to him."
A surprised expression suddenly appeared on Wang Bin's face: "The doctor suggested that Zuo Xiangxian should be allowed to recuperate for a few more days."
"Rehabilitation training is originally the scope of the physical coach's work." Gu Zhizhong paused and then said; "And the Swedish Open is about to start. Time does not wait. We must let Zuo Xiangxian return to form as soon as possible. We are like this For left-handed players, at least in doubles, we still need Zuo Xiangxian."
…
"Coach, are you looking for me?" Li Dai was called into the office by Gu Zhizhong.
Gu Zhizhong motioned for Dai Li to sit down, and then said: "Zuo Xiangxian has rested for five days and will be back tomorrow. I plan to let you be in charge of his rehabilitation training. Is there no problem?"
"Let me be responsible for Zuo Xiangxian's rehabilitation training?" Dai Li was surprised at first, and then immediately nodded in agreement: "I have no problem."
Gu Zhizhong continued: "The Swedish Open is coming soon, so our time is also very tight. I hope that Zuo Xiangxian can recover as soon as possible and then return to training. We still have a lot of work to do before the game. There can be no delay.”
Five days ago, Zuo Xiangxian sprained his foot during training. The examination results showed that there was nothing serious, but he was asked to rest in bed and not engage in strenuous activities, so the training could only be suspended.
After professional athletes are injured, they cannot recuperate slowly like ordinary people. When the injury recovers to a certain extent, they will conduct rehabilitation training to continue to recover. Recovering from injuries through rehabilitation training is much faster than natural recovery, and it can also help athletes reshape their condition.
Therefore, when Zuo Xiangxian returns to the team, rehabilitation training is a must.
However, Dai Li did not expect that Gu Zhizhong would entrust such an important matter to him.
It has been less than a month since Dai Li joined the national table tennis team, and it has only been more than a week since he joined the first team. Ordinarily, matters involving the recovery of the main players should be left to experienced veterans, not those who don't know how to handle it. For newcomers like Li Dai. But Gu Zhizhong still chose Li Dai.
However, Li Dai is not worried about himself. Rehabilitation training is what a physical coach should do. In this regard, Li Dai has sufficient professional knowledge reserves, not to mention that Li Dai also has the "artifact" of rehabilitation massage.
…
Zuo Xiangxian took off his shoes and socks, revealing his purple ankles.
"There's still a lot of congestion." Li Dai asked Zuo Xiangxian to put his shoes back on.
Those purple parts are all congestion, and as long as there is congestion, the injured part will definitely feel pain, so the first thing in rehabilitation training is to eliminate the congestion.
At the same time, Dai Li also noticed that Zuo Xiangxian's injured left calf was different from that of his right calf, which was due to muscle atrophy.
"Five days of rest, coupled with the injury affecting the blood circulation of the calf, actually caused slight muscle atrophy."
Dai Li frowned slightly. If it was just pure desilting and rehabilitation, then the matter would be relatively simple. However, coupled with the recovery of calf muscle atrophy, this rehabilitation training instantly increased the level of difficulty.
"We have to use balance pedals and BOSU balls." Dai Li has already made a training plan in his mind.
Balance pedals are a relatively common piece of fitness equipment that can artificially create an incline, and the slope of the incline can be increased or decreased by adjusting the height of the pedals.
BOSU ball, also called wave ball and balance ball, mainly consists of two parts. The upper part is a rubber hemisphere, and the lower part is a plastic platform. You can also simply think of it as half a yoga ball.
The spherical surface of the BOSU ball is unstable, making it more difficult to perform movements on it, which also increases the scope of exercise. This is a piece of equipment used for static muscle strengthening training and is also standard equipment in gyms or yoga studios.
…
Zuo Xiangxian stood on one foot on the BOSU ball, swaying his body from side to side, trying hard to maintain his balance.
For athletes with ankle sprains, it is very difficult to maintain the balance of the body when standing on one foot. Standing on the BOSU ball, it is even more difficult to find the focus of the footwork, and they can only constantly adjust the body. center of gravity to maintain body balance.
However, this kind of training is very effective for the current Zuo Xiangxian. While adjusting the body's center of gravity, the constantly twisting ankles can accelerate his blood circulation, thus eliminating congestion faster. At the same time, in order to maintain the balance of the body, the legs The legs also need to exert constant force, which also exercises the muscles in the legs and relieves muscle atrophy.
Coupled with Li Dai's Ka rehabilitation massage, Zuo Xiangxian recovered as before in just five days.
…
Gu Zhizhong walked to the training room excitedly.
"Ouch!" A miserable cry sounded, and Gu Zhizhong immediately recognized that it was Zuo Xiangxian's cry.
"Zuo Xiangxian just sprained his foot. Could it be that he was injured again?"
Gu Zhizhong thought of this, took a few steps and rushed into the training room, only to see Zuo Xiangxian lying on the training chair and Dai Li massaging his waist.
"Zuo Xiangxian's waist was already injured, maybe he pressed on the injured area." Gu Zhizhong thought to himself, and then he decided to step forward and give Li Dai a few words, asking him to pay attention to Zuo Xiangxian's waist during the massage. Back injury.
However, the next second, Zuo Xiangxian showed an expression of great enjoyment.
"Forget it, let's go to the infirmary first. Doctor Chen is waiting for me!" Gu Zhizhong thought of this, walked through the training ground and walked directly to the infirmary.
…
National table tennis team medical room.
The team doctor held the latest test results in his hand, with a serious look on his face.
"Doctor Chen, how is Zuo Xiangxian's foot injury? Can he fully resume training?" Gu Zhizhong asked anxiously.
Dr. Chen put down the examination report in his hand, adjusted his glasses with his hands, and then said: "Based on the examination results, Zuo Xiangxian's sprain has healed. There is absolutely no problem in resuming training."
"Then I'll be relieved." Gu Zhizhong breathed a sigh of relief.
"But..." Dr. Chen paused, then continued: "I think Zuo Xiangxian's recovery speed is too fast. According to my expectation, this kind of sprain requires at least fifteen days of rest, and sometimes a month's rest. It’s normal. It’s only been ten days now, and his injury has healed and he has fully recovered.”
"This is probably the effect of rehabilitation training! We have hired a new physical fitness coach named Li Dai." Gu Zhizhong said the number casually.
"I have met that young man." Dr. Chen nodded: "In addition, I also checked his waist injury by the way. His old waist injury has also improved a lot."
"There is such a thing, this is good news! It seems that this Swedish Open, I don't have to worry about the shortage of major generals." Gu Zhizhong's eyes showed a joy.
However, Dr. Chen went on to say: "Zuo Xiangxian's waist injury has been discussed by the two of us before. Unless it is surgical treatment, his injury is irreversible. It is already thankful that it will no longer worsen. But the examination results in my hand show that his waist injury has actually improved! If he has to practice every day, it can be explained medically, but according to the training intensity of our team, this is almost impossible to happen."
"You mean Zuo Xiangxian is recovering from his back injury?" Gu Zhizhong asked immediately.
"You can understand it that way." Dr. Chen nodded: "Irreversible injuries are recovering. To be honest, I have been a doctor for more than 20 years. This is the first time I have seen this kind of situation."
At this second, the scene where Li Dai gave Zuo Xiangxian a waist massage suddenly came to Gu Zhizhong's mind.
"Could it be Dai Li who did it?"
