cut the waves

On a weekend in early April, the provincial team organized the first open water training in Ninggang Seaside Park. A total of more than 40 people came. Dumplings are so lively.

The 10KM swimming marathon takes two hours, and the whole process of high-intensity aerobic will consume a lot of glycogen in the body. Therefore, "replenishment" in the race schedule has also become a very important part.As for when to replenish and how many times to replenish, it is a personal strategy formulated by athletes and coaches.The research suggests that athletes who choose leading tactics should replenish in the middle and early stages, while athletes who choose uniform speed tactics should replenish in the middle and late stages. Yu Yu has not yet figured out the most suitable strategy for him. [1]

If it is an official game, the pontoon of the supply station will be full of coaches, and the colored poles are like "fishing rods", with supply bottles on the top stretching into the sea.Athletes need to swim to the supply platform, find their own coach and pole, get the supply bottle in the "hand-to-hand fight" with a group of people, switch to backstroke and drink while swimming.

However, right now it is only training within the team, so there is no such thing as "finding a coach". All the supply poles are numbered and fixed on the pontoon in an orderly manner, and each athlete has two supply opportunities.

Yu Yu has practiced in the swimming pool for several months, and has practiced everything, except how to replenish.

Before entering the water, he thought to himself: Isn't it just drinking apple juice?What's so difficult about it.

Halfway through the race, when the second lap was over and Yu Yuyou arrived at the supply platform, he was ranked fifth in the echelon, but when he was in front of the supply platform, after being beaten by athletes scrambling for water bottles, he was not only hit on the arm, but also drank Taking a sip of someone else's "foot washing water", the salty sea water mixed with apple juice poured down his throat, and Yu Yu was almost sent away directly.After resupplying and setting off again, Yu Yu found that his ranking had plummeted, and he fell directly from the front row to the back row.

Yu Yu almost had a heart attack because of this sip of supplies, and chased after him angrily, but there was still a full 5000 meters ahead, he disrupted his rhythm in advance, exhausted in the final sprint stage, and only swam ninth in the group.

Today is just a team practice match, but when you think about it carefully, the team qualifying match is only a month away.Does he still have a chance to swim into the top three?

After landing, Yu Yu shut himself up on the spot: "Coach, can I give up the supplies?"

Yan Zheng twitched the back of his head lightly: "You're talking nonsense again! There was once an athlete who gave up supplies in pursuit of performance, but in the final sprint, he had hypoglycemia, his eyes went black, and he almost had an accident. With your weight, every half hour of aerobic needs Do you know how much to make up a glass of apple juice?"

Tao Zebo laughed and took his shoulders, saying that it was the same for the first time he grabbed supplies, and he was stunned when he was beaten for the first time in the competition, so he should practice more and get used to it.

Yu Yu wondered: "...Isn't it against the rules to hit someone?"

Tao Zebo snorted, saying that open waters are inevitable.Sometimes the referee sees physical collisions on the water surface, and will blow the whistle to issue a yellow card warning, but in fact, 70% of the collisions occur underwater, and the referee cannot see them, and there is no reason to explain them.Don't watch any international competitions, just listen to the high-sounding ones, some athletes just don't talk about martial arts.

Yu Yu: "..."

Practice on Saturday morning, lunch at 11:30, and aerobic training for long-distance athletes at one o'clock in the afternoon.Su Liao finished his competition class in the morning and came to Seaside Park in the afternoon.Yan Zheng got a headache when he saw him, and scolded: "Why are you here? Your father told me that this semester's competition class has been changed to a whole day in the morning and afternoon?"

"I don't like the teacher in the afternoon. If you curl up, you will get curled up." Su Liao didn't go into the water, sat cross-legged on the pontoon bridge, took out a competition book, and said with a smile, "Bask in the sun and blow the wind, the weather is cloudy today." OK!"

Yan Zheng was momentarily at a loss for words.This lesson is skipped, and it is impossible for him to send Su Liao back, so he no longer cares about him.

Su Liao was very interested in the row of "fishing rods". When the coach was not paying attention, he deliberately poked Yu Yu's head with the rod when Yu Yu was swimming across the pontoon bridge.

Yu Yu: "..."

The water temperature in April is not too warm after all. After 02:30, the temperature began to drop, and the team leader coach blew the whistle to close the team.

Yu Yu learned from the painful experience and felt that supply is still an important part of the competition. After all, sufficient glycogen is also the basis for sprinting. Once the muscles are weak, it is difficult to swim to a satisfactory result with willpower.Just like swimming pool players will strive to shorten the "turning time", shortening the "recharge time" is also a topic.Compared with the race against time before the finish line, the time saved by resupply seems to be for nothing.

It is rare to have the opportunity to simulate 10km in open water, Yu Yu took the initiative to propose additional training to the coach-how to 'target' his own supply bottle in the first place in the distance, how to swim while drinking to save time, etc.

Tao Zebo was a little surprised: "You have swam [-] kilometers today, why don't you practice more?"

Yu Yu was taken aback for a moment—sixteen kilometers?Has he been swimming for so long today?But he thought about the qualifying competition a month later, gritted his teeth, and said that I should add some electrolytes, the water temperature is not too cold.

Tao Zebo shook his head and went ashore, sighing: "It's good to be young!"

Su Liao picked up a pole and raised it to the surface of the sea with great interest: "Come on, let's practice holding the bottle, right? I'll practice with you!"

After Yan Zheng cleaned up the other poles, he glared at Su Liao: "Don't practice for too long, let him swim for half an hour at most, can you stand alone?"

Coincidentally, Cheng Zhefan took a shower after landing, changed his clothes, and walked onto the pontoon bridge.Seeing that there were two athletes present, Yan Zheng felt relieved, and after a few more instructions, he went to pack the equipment.

Yu Yu was swimming back and forth about 50 meters in front of the pontoon, holding an empty mineral water bottle to practice the skill of "cutting from freestyle to backstroke, drinking while swimming and then switching back to freestyle".

Cheng Zhefan sat down beside Su Liao, and sighed: "Good student, you still skip class?"

Su Liao picked up the mineral water bottle floating on the sea with a net bag, and put it back on the pole: "If you have something to say, just say it."

He also knew that Cheng Zhefan was not someone who liked to chat.

"It's nothing, I haven't chatted with you for a long time." Cheng Zhefan twitched his lips.

Su Liao nodded: "It's been a long time."

"I didn't know until I went to the youth training of the national team." Cheng Zhefan lowered his head and smiled, "How far is the gap between me and those majors."

The National Middle School Swimming Championships represent the highest swimming level of the amateur group in the country, but stepping into the professional group is another matter entirely.

"I just feel very tired and anxious." Cheng Zhefan's voice was not loud, almost drowned by the sound of the wind and waves, "I don't know who to talk to."

Su Liao stared at the silver-blue pole that was only as thick as a pinky finger trembling up and down in the sea breeze, and chuckled lightly: "Man, you have to learn to have some fun for yourself."

Cheng Zhefan asked dully: "How to find it?"

"Look," Su Liao rolled his eyes and revealed a sly smile.Yu Yu was still 30 meters away. He retracted the supply pole, replaced the empty mineral water bottle with Wangzai milk in his bag, and explored into the sea again.

Apparently, Yu Yu also noticed the bottle of Wangzai and immediately became excited.But when he stretched out his hand, Su Liao suddenly raised the pole, making Yu Yu jump into the air.When Yu Yu raised his arm again, Su Liao withdrew the pole a little, and was caught in the air again.In this way, he "led" Yu Yu under the floating bridge inch by inch.

Yu Yu started cursing in the sea, Cheng Zhefan gave Su Liao a speechless look.

Su didn't take it seriously, and narrowed his eyes with a smile: "This is called Diaoyu."

Yu Yu finally grabbed his Wangzai and said "yeah" in the sea.

Cheng Zhefan: "..."

Su Liao gave a "tsk" and said, "It's really easy to catch."

"When you were in the third year of junior high school, you told me that you should have a good competition after high school, and you don't plan to swim anymore." Cheng Zhefan lowered his eyes and looked at Yu Yu, who was happily drinking milk in the sea, "I didn't expect that most of the first year of high school is over, you The sports school is quite frequent. Is it for this? For fun?"

"No, I haven't won the national gold medal yet." Su Liao smiled, "I wanted to retire last year, but didn't you snatch the 200m self-gold medal?"

"If you do a good job in the competition, you can win the national gold medal. I think you may win the gold medal in the World Olympiad." Cheng Zhefan sighed, "If you win the gold medal for the national middle school students next month, will you be able to go back and have a good time? learned?"

Yu Yu finished Wangzai quickly, squeezed the box flat with one hand, and threw it at Su Liao's head.The pontoon floated up and down with the waves, but he missed Su Liao, and hit Cheng Zhefan with a "bang".

Cheng Zhefan's unhappy face suddenly turned darker.

Yu Yu struggled to climb up the pontoon: "What are you two whispering?"

Su Liao glanced at Yu Yu and said carelessly: "Take it first and then talk about it."

Seeing Yu Yu coming up, Cheng Zhefan got up and wanted to leave, and slightly pressed his right hand on Su Liao's shoulder: "Human energy is limited, brother Liao, don't yaw."

Su Liao: "..."

"Let's go." Cheng Zhefan glanced at Yu Yu indifferently, turned his head and left.

Yu Yu scratched his head, wondering what kind of charade these two were playing.When Cheng Zhefan was far away, he asked Su Liao in a low voice, "Are you and Cheng Zhefan very familiar?"

Su Liao said "Yes": "Zhe Fan and I are in the same elementary school, in the same class, and we have been swimming together in the sports school since we were young, so we are quite familiar."

Yu Yuxin said it's no wonder, Cheng Zhefan hardly talked to anyone, and he didn't have a good look at anyone, and he only "lended the net" to Su Liao.After he did the math, he thought that the two had known each other for ten years without saying anything.Not just "knowing", but training together for ten years.

Immediately, Yu Yu became even more upset when he saw Cheng Zhefan.He groped for a long time, and found that this "doubly uncomfortable" seemed to be because of Cheng Zhefan and Su Liao's ten years of acquaintance, he actually played in the water by himself in Huaxi.

After Yu Yu changed his clothes, he still couldn't help being curious: "What the hell are you talking about with your face paralyzed?"

Su Liao replied dryly: "If you criticize me, I can't skip class."

"Did you skip class?" Yu Yu was shocked when he remembered that today is Saturday, "Have you skipped class before? This is not the first time you have skipped class, right? I'm growing up, Su Liao! "

Su Liao: "..." Only Yu Yu would regard "skipping class" as "improvement", right?

"No," Yu Yu frowned in wonder, "You don't have to go to sea today, why are you skipping class?"

"Why is today—" Su Liao tilted his head, "What day is it?"

"First open water practice this year?"

Su Liao: "..."

"Happy birthday, idiot." He put his hands on Yu Yu's shoulders, made him turn 90 degrees to the right, and pushed Yu Yu to the souvenir shop in Ninggang Haibin Park, "I ordered a big tiger for you whale."

Last May, in this seaside park, the big killer whale that Yu Yu was won by Su Liao, the same brand, the same size.
