Du Liang obviously knew his shortcomings. As a senior student who can be admitted to Tsinghua University, Du Liang is not the kind of person with a simple mind and developed limbs. On the contrary, he has a high IQ and is good at finding and thinking about problems.

Tsinghua University does not have a physical education department. Even high-level athletes who want to enter Tsinghua University must normally take the entrance exam, and then enter by way of the score reduction of sports specialty students, and this score drop will not be very large and can be enjoyed. It is already very good to drop admissions at 30-50 points. The kind of college entrance examination with a score of 100 points will never appear in Tsinghua University's special sports recruitment.

Of course, the admission scores of the provinces are different, and the difference is still very large. But it is undeniable that if you want to enter Tsinghua, you must be the most outstanding talent in your province.

So in the sports department of Tsinghua University, there is also a group of characters with academic hegemony. Li Dai doesn't need to talk too much, only need to explain the key parts, and the athlete can understand what Li Dai really means.

At this time, Du Liang had been calmed down by what Li Dai had just said.

"All of my flaws were mentioned by him. How did he know that he just came yesterday, and yesterday afternoon was the most routine training? Is it possible that he had already seen me by yesterday afternoon? The technology is flawed. The hip extensor and ankle muscles contract too early. This is a very subtle flaw. I also took the training video and went to the Sports Human Science Laboratory. I asked Professor Zhang to analyze it with a computer system. You know, this coach Li can even see it with his eyes! "

At this moment, Du Liang put away his contempt for Li Dai, but asked sincerely, "Coach Li, how can I improve my shortcomings?"

"I have prepared a short-term training plan for you, let's see it!" Li Dai handed a piece of a4 paper to Du Liang.

Du Liang took his hands hurriedly and looked carefully.

"This is a half-height run with legs raised," Du Liang asked.

"Yes, it's a half-height run with a small leg lift. Have you been in touch before?" Li Dai asked.

"No, but I saw it once in a journal." Du Liang replied.

"Your question, according to the traditional training method, the training method of small step running is probably used, but small step running is very useful for beginners. For athletes like you who have certain sprint skills, the effect is not obvious. "" Li Dai explained.

"Yes, I have been using the small-step training method to solve the problem of contraction of the hip extensor and ankle muscle groups too early, but there is almost no effect." Du Liang nodded quickly, he thought Li Dai said his own Heart.

Li Dai went on to say, "So I chose the training method of half-height leg-lifting and small-step running, which can better emphasize the movement and speed of the foot and ankle. The height of the swing leg swing is about 30 degrees to 40 degrees from the center horizontal line. When the foot falls, the hip is extended quickly. By extending the hip and pressing down, the foot is quickly grounded. I will teach you personally in a while, Perform technical training on this action. "

"Thank you Coach Li!" Du Liang's sincere face, at this time he was already convinced of Li Dai!

Being able to find problems is just the first step, and being able to solve them is the most critical. Du Liang knew his technical flaws and tried to solve the flaws through training, but the effect was not satisfactory.

But Li Dai can propose a solution to the problem, which increases his bargaining power and convinces Du Liang.

Several other people saw this scene and their minds became active again.

"Although Coach Li is very young, it seems that he still has some skills. He can actually see Du Liang's shortcomings and can also propose solutions to improve the shortcomings. Previously, he underestimated this coach Li."

"Coach Li said very well, it seems that he doesn't have to worry about blindly arranging his training plan."

"Is coach Lee really capable, or is it a coincidence or should I look at it again!"

At this time, Li Dai ordered a second name: "Xin Xiaotian, you are out!"

Xin Xiaotian stepped forward immediately. He looked at Li Dai with interest, as if he wanted to hear it. Li Dai would also tell what he knew.

"Xin Xiaotian, your problem is that in the process of running, you only pay attention to raising your legs, and don't think about sending hips. You lack the initiative in hip extension adaptability, which also causes you to lack front kick distance." Li Dai Said.

Xin Xiaotian smiled disdainfully, he retorted: "My technique is to allow the legs of the swinging legs to quickly drive back before landing, so that you can get more pedaling force. And you say me The lack of initiative in hip extension is due to the fact that during high-speed running, the forward swing is high enough! My technique can make the resistance of the front pedal less. "

If you are a normal athlete, you probably wo n’t refute the coaching like this, but Tsinghua students are all arrogant, Xin Xiaotian ’s usual academic performance is very good, and the sprint level is also second in the Tsinghua sprint team, second only to Niu Guohong From the earliest to the most top-ranking people, they are born with pride and confidence, and naturally dare to refute Li Dai.

"Ha, Xin Xiaotian refuted that coach Li, now there is lively to watch."

"Xin Xiaotian seems to have self-taught sports training related courses. In sports training, his theoretical knowledge is very rich, that is, a few master's degree assistants, sometimes they can't say Xin Xiaotian."

"Look at Coach Li's answer. It's a mule or a horse. If you can't figure out Xin Xiaotian, this coach Li will be embarrassed today."

The remaining athletes thought about each other, but they all showed a lively look ~ lightnovelpub.net ~ Li Dai was not panicking, he continued to say in a slow tone: "You are running, swinging forward It ’s not just high enough, but the front is too high! I think you should usually do more high-leg exercises. "

"How do you know?" Xin Xiaotian's expression changed slightly. He was asked by Li Dai, who was not convinced.

"The training of high leg running has obvious positive and negative effects on the sprint technique. This training can indeed correct the shortcoming of the front swing is not high enough. In an instant, the leg swing height is limited to a certain range, not the higher the higher. The key is to swing far! "

Li Dai said, some hands began to make gestures: "When running at high speed, there will be a more obvious twist of the hip joint. The running technique you are using now is to lose the necessary and reasonable forward pedaling distance. In exchange for reduced resistance, but this will have a certain lead in the starting phase, but it also causes a loss of step length during the run, and your attention will be focused on the landing angle, which will inevitably cause hip, knee and The stiffness of the ankle joint is due to the tension of the knee joint. "

Li Dai paused, and he found that Xin Xiaotian had completely listened to his words and was still caught in thought.

"The most important thing is that your high-leg lifting technique will have physiological effects, such as hip contraction and pelvic sitting, which will affect the step length and running speed." Dayton, then said: "So your technical characteristics must be changed!"

When the words "must be changed" were spoken, Xin Xiaotian was completely out of the recklessness just now, and he showed the same shock expression as Du Liang.

"This coach Li said very well!" Xin Xiaotian was already convinced by Li Dai.
