The next day, when Ye Qin saw Yan Ning appear on the playground of Xiushui No. 2 Middle School, he was a little stunned.

After more than ten days of winter vacation, I saw Yan Ning again and found that her complexion was terrifying, her face was pale, her dark circles were very heavy, and her eyes were faintly bloodshot.

"Teacher Yan, are you sick?" Ye Qin's first reaction when he saw Yan Ning was this.

"It's okay, I'm a little busy during the winter vacation, and I haven't slept well." Yan Ning coughed lightly and shook her head a little tiredly, "Ready to start training." ”

"Okay." Ye Qin nodded, seeing that Yan Ning didn't want to say more, he didn't ask any more, but said, "Then what am I practicing today?" Or is it still the same as before? ”

Before the holiday, Ye Qin had been training according to Yan Ning's saying that speed and resistance were the main ones to strengthen his running ability, and Yan Ning said that he would formulate a new training plan for him after the holiday.

"Let me give you a question, do you know why track runners always run to the left?" Yan Ning didn't directly talk about the training project, but asked a somewhat irrelevant question.

"Huh?" Ye Qin was slightly stunned, then thought about it seriously, and then shook his head and said, "I don't know." ”

He started with contact running, and it seemed that everyone had agreed to run to the left in a counterclockwise direction, but no one really seemed to say why.

"The rule of running to the left side of the track race was established in 1912 when the IAAF was founded, and there are many reasons, it is generally believed that the human heart is located on the left side, so the center of gravity is easy to deviate to the left, and some people's starting foot is mostly the left foot, and the center of gravity is also biased to the left foot. In addition, some physics says that the earth rotates, and the body will be particularly adapted to running to the left......"

Ye Qin nodded as if he didn't understand, and said a little puzzled: "Teacher, why are you talking about this?" ”

Yan Ning gently rubbed her temples and said slowly: "You are going to participate in the provincial youth track and field championships soon, and I won't talk about other things, just talk to you about curve skills." Let's go to the other side of the runway. ”

"Okay." Ye Qin nodded, glanced at Yan Ning, and always felt that the other party's expression was a little strange.

The training conditions of Xiushui No. 2 Middle School are limited, but fortunately, the school occupies a large enough space at the beginning, and a 400-meter standard track is enough on the playground.

Standing at the starting position of the curve of the runway, Yan Ning made a movement to run the corner, "When running the corner, pay attention, the center of gravity of the body should be slightly tilted inward, pay attention to what I said is the center of gravity." A 200-meter corner, the distance is about 114 meters, and there are two corners in 400 meters, you can imagine how important the acceleration of the corner is. ”

"When running in a corner, the swing of your arms and legs should be roughly parallel to the direction of your tangent. When we run, the body is in the back pedal stage, and the rapid and powerful swing of the legs and arms can make the center of gravity of the human body gain greater acceleration. The swing of the left arm is slightly away from the body, and the swing of the right arm is closer to the torso, which is the position, the swing amplitude of the right arm and right leg is slightly greater than that of the cheating and the left leg, when the right arm swings forward, the elbow and upper arm are close to the torso, and the anterior lead of the hand and forearm is to swing in the direction of the longitudinal axis of the human body, and this is the case............ You have to prepare yourself for the curve when you take two steps before entering the straight into the corner. ”

"Do you understand what I say?" Yan Ning cooperated with his hands and feet to demonstrate the technical points, and turned his head to look at Ye Qin.

"I guess I understand, but it seems to be a little different from what you said before." Ye Qin recalled the action that Yan Ning had demonstrated just now, and scratched the back of his head.

"What did I say before?" Yan Ning looked up at Ye Qin.

"When you talked about corners before, the upper body was tilted a little bit inward, and then the left hand swung the arm a little bit more, and the right hand a little bit more......

"Not so." Yan Ning didn't wait for Ye Qin to finish speaking, and interrupted, "I may not have been careful enough before, when running in a corner, I don't tilt my upper body to the inside, this is not right, it will cause the body to tilt centripetal force, waste energy and cause tension in the motor organs." ”

Yan Ning said, gesturing with both hands, the palm of his left hand was regarded as the ground, and the palm of his right hand was cut diagonally, "When running in a corner, the body should be the ground should be an angle, from head to toe as a whole, not an upper body tilt." ”

"Understood."

Ye Qin watched Yan Ning's gestures, nodded, his lips moved slightly, and then silently repeated it.

"You make a few trips to experience it for yourself."

Yan Ning looked at Ye Qin and muttered in a low voice, knowing that this was Ye Qin's learning style, as long as she talked about the technical points, Ye Qin would completely write them down first, whether she understood it or not. I can't say whether this way is good or bad, but among the few sports students she has led, Ye Qin's dedication definitely exceeds that of most people.

The carving of running technique is a long-term process, which requires the body to change and adapt little by little, and when running, it is also necessary to experience the feeling after the subtle changes, and then form a habit, which is impossible to fully grasp just by talking about nature.

The footsteps on the track sounded again, and Ye Qin's figure began to run over and over again in the corner, first to the innermost first, and then to the outermost eighth.

Every time he ran through the corners and every time, Ye Qin carefully experienced the changes when he ran through the corners quickly. It looks like a very simple corner, but subtle technical improvements can make it easier and more comfortable.

Watching Ye Qin begin to enter the training rhythm from a distance, Yan Ning stood on the sidelines, exhaled lightly, and frowned inadvertently.

She has been holding back a lot of energy in her heart, Ye Qin did not go to the professional team, and stayed in Xiushui No. 2 Middle School, she really hopes to train Ye Qin, and she doesn't want Ye Qin to be delayed in her hands. and the principal Wen Tongshi fought for various benefits, just to let Ye Qin have as good conditions as possible. At this stage, there is no advantage in the age of practicing sports, and if it is delayed any longer, it is likely that a good seedling will be abandoned in the future.

This winter vacation, she stayed up all night studying the coaching books and training programs brought back by the trustees, but the more she knew, the more she found that she knew too one-sided, so that she had a feeling of not knowing where to start.

In her career, she listened to the coach and then strictly implemented it, did it, and trained, but a lot of the evidence in it was not very clear, and she didn't know why it was, and she didn't think about such a profound layer.

As a physical education teacher, what she has learned and understood is enough to deal with, and some simple training methods and methods can be clearly transmitted to students, but if she wants to go further and provide Ye Qin with professional training, her personal qualities alone are a little insufficient.

The teacher imparts knowledge, instills the main points of knowledge to the students, and digests and understands. The coach focuses on summarizing the specific situation of the training object, analyzing his existing problems, and then specifying a plan and giving solutions.

For example, during her winter vacation, she analyzed the technical characteristics of two sports students, Liu Yizhen and Li Jianchao, Liu Yizhen's soles of his feet were supported on the ground and he had great strength backwards, and his backward legs were fully extended. However, the thigh swing ability is very poor, and the thigh swing forward is not open to the horizontal angle.

Li Jianchao's forward swing thighs can be stretched, but the landing point of the supporting feet is often more obvious in front of the body projection, and the support is not fully stretched, looking a little "sitting" and running.

She found the problem, but what the two sports students needed was not for her to just dig out the problem, but for her to provide a suitable improvement plan and improvement plan.

And this kind of planning plan is not overnight, and the single-person targeted training model is simply not realistic at present.

As for Ye Qin, she has only now begun to build a file, and her technical characteristics are still at the surface stage, let alone the in-depth formulation of training plans.

She has read several training plans from the provincial team, deleted and changed them, and even formulated several training improvement plans based on these.

But after many plans were made, she herself could see that it was not suitable and too superficial. The more she tries to be on par with professional coaches, the more problems she encounters. The level is not enough, there is no assistant, no one can rely on it, she can only rely on herself to continue to explore, put pressure on herself, no one to analyze, discuss, and make plans, and she alone has no way to catch it.

Looking at Ye Qin, who was training in the field, she found that another problem was in front of her.
