Swimmers are generally taller, for swimming, tall athletes mean more advantage, tall people generally have excellent arm span, which can achieve faster forward speed when paddling, and people with longer arms will also be the first to touch the line when approaching the finish line.

Of course, if you are too tall, it will be difficult for the body to form a streamline, and you may encounter greater resistance in the water, so people who are too tall are not suitable for swimming.

The height of the swimmers of the national team is generally between 1.85 meters and 2 meters, while the height of the female players is generally more than 1.70 meters, and there are even many female athletes who are 1.80 meters tall. Take Yu Feifei as an example, her height is 1.72 meters, but she can only be regarded as short in the national swimming team.

In terms of weight, female swimmers generally weigh between 60 and 65 kilograms, while taller female athletes may weigh more than 65 kilograms.

For ordinary women, if they are 1.70 meters tall and weigh 60 kilograms, they may feel fat, but the body fat rate of athletes is relatively low, so with the same height and weight, athletes will definitely look thinner than ordinary people.

A few years ago, when Yu Feifei broke the world record, she weighed only 55 kilograms, but considering that Yu Feifei's body was not fully developed at that time, 55 kilograms was a suitable weight. But as she grew older, Yu Feifei reached the period of growth and development, and her weight soared to 70 kilograms.

According to the assessment of the national team coach, if Yu Feifei wants to restore the level of the world champion, her weight needs to be reduced to less than 62 kilograms, and the athletes in the national team who are about the same height as Yu Feifei weigh about 60 to 63 kilograms, which means that Yu Feifei needs to lose at least 8 kilograms, that is, 16 kilograms.

……

In the training room, Li Dai and Xu Zhongyi were arguing-for-tat, and Yu Feifei next to him wanted to persuade him, but he couldn't interject at all.

At this time, Yu Feifei finally heard Li Dai's call and asked her to get on the scale, Yu Feifei couldn't help but be happy in her heart, but she still looked at Xu Zhongyi first, as if she was asking Xu Zhongyi's opinion.

"Go and weigh it!" Xu Zhongyi looked at Li Dai with contempt, and continued to say: "I want to see what tricks you can play." ”

Li Dai made a gesture of please, and then said: "Coach Xu, please, let's go and see how much Yu Feifei has lost weight in these days of training." ”

Xu Zhongyi snorted coldly and walked to the electronic scale, while Li Dai followed behind Xu Zhongyi.

Yu Feifei stepped onto the electronic scale, then stabilized her body, and the numbers on the electronic scale stabilized.

"Coach Xu, please take a look!" Li Dai pointed to the number with his hand.

"63.11 kg? 126 pounds? Xu Zhongyi was suddenly shocked, and his expression changed, he looked up at Yu Feifei, and then looked at the numbers on the electronic scale, his face was full of incredible expressions.

"How is this possible, weight loss of at least 14 pounds! Fei Fei, it's only been about twenty days since you cleared the city! How did you lose so much weight in such a short period of time? Xu Zhongyi asked.

didn't mean Fei Fei answered, but Li Dai took the lead in saying: "Yu Feifei can lose so much weight, of course, my weight loss exercises have played a role!" ”

"Nonsense! Just your broadcast gymnastics can make Fei Fei lose fourteen pounds! Xu Zhongyi still didn't believe that weight loss exercises really worked, he turned his head and asked Yu Feifei with a serious face: "Feifei, tell me honestly, how did you lose weight?" Are you taking medication? ”

"No, coach, I didn't eat indiscriminately. I was able to lose so much weight, really because of Coach Li's weight loss exercises. Yu Feifei said.

Xu Zhongyi knew that Yu Feifei would not lie to himself, but he still didn't believe that something that looked the same as broadcast gymnastics could make Yu Feifei lose weight in a short period of time, and it could solve problems that the national team physical fitness coach and university nutrition professor could not solve. This is completely contrary to Xu Zhongyi's normal cognition.

According to the electronic scale, Yu Feifei's current weight is 63 kilograms, and the goal of 62 kilograms is already close at hand, which means that if Yu Feifei can find his form, he will once again have the strength of the world champion.

For Xu Zhongyi, all this came too suddenly, the so-called hearing is false, seeing is believing, although Xu Zhongyi saw the figure of 63 kilograms with his own eyes, but his heart is still full of doubts.

"It's impossible, it's already very difficult for athletes to lose weight. It's only been more than 20 days, and if you want to lose two or three pounds, I still believe that I lost 14 pounds all of a sudden, which is completely unreasonable. Something must have gone wrong! Let me go through it carefully......" Xu Zhongyi quieted down and began to carefully recall everything that had just happened.

Suddenly, Xu Zhongyi turned his head, pointed to the electronic scale, and said sharply to Li Dai: "I understand, there is a problem with this scale, there must be a problem with this electronic scale, you are doing it, right?" ”

Li Dai smiled disdainfully, and he pointed to the side: "If you think this scale is not accurate, there is another one next to it, you can also go up and try it." ”

"Who knows if you've done anything with that one! If you can change one, you can change two, maybe you can change both scales. Xu Zhongyi snorted coldly and expressed his distrust of Li Dai.

"Well, you weigh yourself on the scale, you should know very well! In this way, it can be verified that this electronic scale is accurate. Li Dai said.

Yu Feifei immediately gave up his position, and Xu Zhongyi strode onto the electronic scale.

"85.53 kilograms, Coach Xu, I can't see it, you are quite heavy, more than 170 pounds!" Li Dai said teasingly.

But Xu Zhongyi was silent, of course he knew how much he weighed.

"I just weighed the day before yesterday, when my weight was more than 172 pounds, less than 173 pounds, although this scale is different from the day before yesterday, but it is only a pound short, this error is within the allowable range. So this electronic scale is accurate? ”

Xu Zhongyi couldn't help but look at Yu Feifei, she had lost 14 pounds, and if she wanted to say that the electronic scale could weigh an error of 14 pounds, Xu Zhongyi felt that it was impossible.

"That's not right!" Xu Zhongyi suddenly shouted: "I understand, Fei Fei, you have lost so much weight in such a short period of time, you must be sick!" Let's go back and have a good rest, and tomorrow I'll take you to the hospital for a comprehensive physical examination! ”

Li Dai on the other side showed an expression of crying and laughing.

"This Xu Zhongyi, why don't you believe that my weight loss exercises are really effective!"
