During the Spring Festival holiday in the next few days, Yao Aijun was spending time with his family. Visiting temple fairs, watching TV, even just chatting makes the empty, lonely and cold soul of the previous life wander in the pulse and warmth of the family. Until the morning of the seventh day of the new year, Wang Aiping reluctantly left the house, stepped on the return train, and roared away.

At this time, Yao Aijun has completed all the literature and history courses in the first year of junior high school, mathematics, physics and chemistry, and has mastered basic formulas and simple examples, which are more strengthened by a large number of exercises; His own sports theory has also begun to see the structure, and he is only waiting for it to be gradually supplemented and then put into magazines to attract the attention of the academic community.

At the beginning of 1991, Yao Aijun was looking forward to it.

……

As one of the head coaches of the provincial team, Luqi still has a lot of work to arrange. By the time he came to Nancheng with Lu Hang, it was already the ninth day of the first month.

Lu Hang's roaring couldn't stop for a moment, and he put down his luggage and rushed over to the Children's Palace that afternoon. Then, naturally, they ate behind closed doors - how could any of the local training classes open a few years ago, and every household is still waiting for the Lantern Festival on the fifteenth day of the first lunar month!

When he came back to his senses and rushed to Yao Aijun's house, Yao Aijun was still confused, didn't he call to say that he was in the car of the ninth year of junior high school, and he thought that he would come over for training tomorrow. Unable to resist the stubborn training maniac, Yao Aijun changed his clothes and accompanied him to Coach Wang's house to find someone, and Coach Wang's family simply went out with the whole family.

One blow of strength, then decline, three and exhaustion.

Lu Hang had been sitting on a long-distance bus in the morning, bumpy for nearly ten hours, and was hit by such a series of blows, no matter how high his interest was.

"Are you still going to Coach Chen?" Yao Aijun asked him.

Lu Hang sighed and waved his hand: "No, let's go tomorrow." Today the master is unlucky. ”

Yao Aijun smiled, this kid is really interesting.

Although Nancheng is the largest inland water system, it is very dry in winter. The two walked all the way back, and the winter sun still smelled warm in the afternoon.

"I said, you just left Coach Lu out?" Yao Aijun asked.

"Huh? I came out with my stuff in it. Lu Hang looked at him inexplicably.

Yao Aijun rolled his eyes, and said in his heart, Coach Lu, I really sympathize with you, there is such a precious apprentice, I can't help but give some advice: "You have to live in Nancheng for almost 2 weeks, and you have to buy some daily necessities to live in a guest house." You're just going to let Coach Lu cook the whole dish for you? People say that there is something to do for the disciple to do his job, but it is the other way around for you! ”

Lu Hang looked dazed, how could he worry about this!

Yao Aijun couldn't help but sigh when he saw him like this, didn't he have such a heartless heart back then, and he threw himself on training. The number of these interpersonal exchanges was realized little by little after he had an accident later, how many walls he encountered and suffered in society when he was alone.

Along the way, Yao Aijun accompanied him to the department store to buy some daily necessities, and then went to the vegetable market to buy some cooked fruits, and sent people back to the guest house.

"Did you give money at home?"

"Yes, in addition to my own weekday savings, my family also gave 500 yuan of pocket money. Probably one or two thousand. ”

Yao Aijun was speechless, this is really a master who is not bad for money. One or two thousand in this year is enough to catch up with the living expenses of many families for a whole year. "Then you pay attention later, there is a place to spend money, and you have a little eyesight!"

"I know that!" Lu Hang said happily.

Yao Aijun rolled his eyes, you know? Know a fart! Starting from the matter of coming to Nancheng itself, you don't have a place to "understand" it!

……

The next day, eight o'clock in the morning.

When Yao Aijun arrived at the Children's Palace, the three coaches plus Lu Hang had already arrived.

Yao Aijun hurriedly went to the locker room to change his clothes, and when he came out, he only wore a set of cotton sportswear. It's still a little cold in the winter, so I quickly warmed up. During the warm-up time, Coach Wang took out a chart of the human body structure and hung it on the side, and began to give them a brief introduction.

There are several key muscle groups involved in diving, mainly including the neck, shoulders, abdomen, back, wrists and legs. It can be said that it covers the whole body from top to bottom. This is also the reason why diving is very difficult to practice, and diving is one of the few sports that has no fixed event.

This non-fixed refers to whether the athlete's posture in the sport is combined with other force points.

For example, in track and field events, whether it is a long jump or a run, both feet land on the ground and get grip and propulsion from the ground, which is a fixed sport; The rings, uneven bars, etc. of gymnastics are typical upper fixations.

These projects with fixed force points will focus on strengthening the exercise of specific force parts. Diving, on the other hand, is a way of doing work without fixed muscles that is completely detached from the support point from the beginning of the jump and is all done in the air. It is precisely because of this non-fixed method that the special strength training of diving has met far more demanding requirements than other events.

Wang Dongmei found a whip out of nowhere, pointed to the muscle anatomy diagram and talked about the past in detail, analyzing the muscle changes and work methods in the diving action, as well as the shortcomings of the existing traditional training methods.

Let's start with the take-off. The take-off is the action at the beginning of a diving event, with a focus on developing bounce and explosiveness. In this regard, the young players are light, and they will first start training and jumping, and then develop to learn to press the board and plywood, and then gradually develop to the springboard project.

To develop bounce power, it used to be practiced by relying on different forms of squats. For example, weighted squats, weighted half-squat jumps, single-legged full squats, weight-bearing knee jumps on the mat, and so on.

This method does not conform to the actual situation of the 130-150 degree angle of the knee flexion in the diving event. It not only increases the joint strain in the knee area, but also does not promote the development of small muscle groups around the knee well, and does not have a good training effect on the bouncing force control of the jump.

This was followed by an aerial leg session. This is a very common point deduction.

The reason for the split leg in the air is that the diving sport flips quickly in the air and has no way to borrow power. Usually, the daily activities of the normal human body are based on the ground, and the body itself is told by the somatosensory information of people since childhood, and the lower plate must be stable, so the muscle groups of the human legs are developed and structurally suitable for gravity.

Diving, on the other hand, requires the body to roll in the air, which is very contrary to the human body's somatosensory experience. These muscle groups required to control the legs, such as pubis, adductor longus, adductor brevis, adductor magnum, etc., are rarely involved in land sports, and it is difficult to imitate them and train them in a targeted manner.

Just said that one item was in the past, and when Wang Dongmei said about it, Yao Aijun's warm-up was also completed.

Wang Dongmei led the people to the equipment area, and let everyone see how Yao Aijun's training methods were different on the basis of the theory just now.
