Born to Run

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

　　 More than ten days after a winter vacation, I saw Yan Ning again and found that her expression was terrifying, her face was pale, dark circles under her eyes were heavy, and her eyes were 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 winter vacation, and I didn't sleep well." Yan Ning coughed lightly, and shook his head a little tiredly, "Get ready to start training."

　　 "Okay." Ye Qin nodded, watching Yan Ning didn't want to say more, he didn't ask any more, instead said, "Then what am I practicing today? Should I follow the previous one?"

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

　　 "Ask you a question first, do you know why track running always runs to the left?" Yan Ning did not directly talk about the training event, but asked a somewhat unrelated question.

　　 "Huh?" Ye Qin was taken aback for a while, then he thought about it, then shook his head and said, "I don't know."

　　 He started from contact running. It seems that everyone has agreed to run counterclockwise to the left, but no one really seems to have said why.

"The rule of running to the left in track races was set in 1912 when the IAAF was established. 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 shift to the left, and most people’s jumping feet are left feet. The center of gravity is also to the left foot. In addition, there are some physics that say that the earth rotates, and running to the left will make the body particularly adaptable..."

　　 Ye Qin nodded his head seemingly understanding, and said a little puzzled: "Teacher, why are you talking about this?"

Yan Ning gently rubbed her temples and slowly said, "You are about to participate in the provincial youth track and field championships. I won't talk about other things, so I'll talk about cornering skills with you. Let's go to the runway. there."

　　 "Okay." Ye Qin nodded and glanced at Yan Ning, always feeling that the other person looked a little strange.

The training conditions of 　　 Xiushui No. 2 Middle School are limited, but fortunately the school area was big enough at the beginning, and the playground was enough to mark a 400-meter standard track.

Standing at the starting position of the corner of the runway, Yan Ning made a bend movement. "When running a corner, pay attention. The center of gravity of the body should be slightly tilted to the inside. Note that I am talking about the center of gravity. A 200-meter curve. , The distance is about 114 meters, and there are two corners at 400 meters. You can imagine how important the acceleration of the corners is."

"When you run on a curve, the swing direction of your arms and legs is probably parallel to the direction of your tangent. When we are running, our body is in the stage of back kicking, and the legs and arms swing quickly and vigorously, so that the center of gravity of the human body can be obtained. Greater acceleration. The left arm swings slightly away from the body, and the right arm swings closer to the torso. This is the position. The swing amplitude of the right arm and right leg is slightly larger than the cheating and the left leg. When the right arm swings forward, the elbow and The forearm is close to the torso, and the forward leading route of the hand and forearm is swinging to the longitudinal axis of the human body, that's it............You are two steps before the straight into the curve, and you must prepare for the curve running. ."

　　 "Can you understand what I said?" Yan Ning demonstrated the technical points with his hands and feet, turning his head to look at Ye Qin.

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

　　 "What did I say before?" Yan Ning raised his head and glanced at Ye Qin.

　　 "When you used to talk about corners, your upper body was slightly tilted toward the inside, and then the swing of your left arm was smaller, and the swing of your right hand was larger..."

"That's not the case." Yan Ning didn't wait for Ye Qin to finish, and interrupted, "I may not be careful enough before. When running in a curve, the upper body is not tilted to the inside. If this is wrong, it will cause the body to tilt and waste. Energy also causes tension in the motor organs."

Yan Ning said, gesturing with both hands, the palm of the left hand was taken as the ground, and the palm of the right hand was cut obliquely. "When you run on a curve, your body should be on the ground. It should be an angle, from head to toe, not an upper body. tilt."

"understood."

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

　　 "You run a few times and experience it by yourself."

　　 Yan Ning watched Ye Qin mutter in a low voice, knowing that this is Ye Qin's learning style. As long as she talks about technical points, Ye Qin will write it down completely regardless of whether she understands it or not. It is hard to say whether such a method is good or bad, but among the few sports students she has taken, Ye Qin definitely surpasses most of them.

The sculpting of running technology is a long-term process. It requires the body to change and adapt bit by bit. When running, you also need to experience the feeling of the subtle changes, and then develop a habit. It is impossible to completely master it by just talking about nature. .

　　 The sound of footsteps on the runway sounded again, and Ye Qin's figure began to run over and over the corners, first on the innermost track, and then on the outermost track.

　　 Every pass and every turn of the curve run, Ye Qin carefully experienced the changes when he ran through the curve quickly. It looks very simple to run in a corner, but subtle technical improvements and adjustments can make people run easier and more comfortable.

　　 Watching Ye Qin start to enter the training rhythm from a distance, Yan Ning stood by the sidelines, exhaled slightly, and frowned inadvertently.

　　 She has been holding back her heart. Ye Qin did not go to the professional team and stayed in Xiushui No. 2 Middle School. She very much hopes to train Ye Qin, not wanting Ye Qin to be delayed in her hands. The purpose of fighting for welfare with the principal, Wen Tongshi, is to enable Ye Qin to have better conditions as possible. At this stage, there is no advantage in the age of practicing sports. If there is any delay, it is very likely that a good seed will be abandoned in the future.

This winter vacation, she stayed up all night and studied the coaching books and training programs brought back by her trustees, but the more she understood, the more she found that she knew too one-sidedly that she had nowhere to start. a feeling of.

In her previous career, many things were listened to by the coach, and then strictly implemented, done, and trained. However, many of the reasons inside were not very clear. I knew it and did not know why, and I had never thought of such a profound one. Floor.

As a physical education teacher, what she has learned and understood is enough. Some simple training methods and methods can be clearly conveyed to students, but if you want to go further, provide professional training to Ye Qin~www.wuxiaspot. com~ Her personal qualities alone are not enough.

　　Teacher is to impart knowledge, instill the key points of knowledge to students, digest and understand. The coach focuses on summarizing the specific situation of the training object, analyzing his existing problems, and then designating a plan and giving a solution.

　　 For example, during her winter vacation, she analyzed the technical characteristics of two sports students, Liu Yizhen and Li Jianchao. Liu Yizhen’s feet were supported on the ground and exerted great strength backwards, and the back kick was fully extended. However, the ability to swing the thighs forward is very poor, and the thighs cannot be pulled apart from the horizontal plane.

　　 While Li Jian can stretch his thighs forward by swinging forward, but the landing point of the supporting foot is often more obvious in front of the body projection, the support is not fully stretched, and it looks a bit "sitting" and running.

　　 She found the problem, but what the two physical education students need is not just to dig out the problem, but to provide a suitable improvement plan and improvement plan.

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

　　 And Ye Qin, she has only started to build files now, and the technical characteristics of Ye Qin are still at the superficial stage, let alone making in-depth training plans.

　　 Several training plans obtained from the provincial team, she herself has read it several times, deleted, changed, and even made several training improvement plans based on these.

　　 But after many plans were done, she herself could see that it was not suitable, too superficial. The more she wanted to be in line with professional coaches, the more problems she encountered. The level is not enough, there is no assistant, and no one can rely on. She can only rely on her own continuous exploration and self-pressure. No one analyzes, discusses, or makes plans. She alone cannot catch up with her.

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