Wearing a heavy coat and chasing into the rest area, Ye Yu lay directly on the bench when he relaxed, and he didn't bother to take a shower.

"Ye Yu! You little head son! You're stealing my tricks! It's so angry! Fei slapped Ye Yu's waist, and someone in pain jumped up directly from the chair.

"Ye Fei, what are you doing! Murder my brother! Do you know what it means to be an eldest brother as a father! I'm your dad! Ye Yu ravaged his sore waist, this dead girl doesn't know how heavy it is!

"Let Daddy hear and beat you to death!" Fei pouted, "You are so arrogant with my skills!" ”

Ye Yu pulled the towel around his body and turned around and entered the shower room, directly taking Fei's words as wind in his ears.

"Did you hear me?"

"Ms. Ye Fei, I'm your brother! Why are you going to chase me with a little trick of yours? Ye Yu said leisurely and leisurely.

Fei pinched his waist and stood at the door, waiting for Ye Yu to come out.

"Don't you have your own way? Do you know how hard it will take my skills if you lose with my methods! ”

"Isn't that number one?" Ye Yu opened the door and replied, his sister is really serious, "Give me the training jacket on the chair." ”

Although he was arguing, Fei still obediently turned around and took out a half-thick training coat in the bench's bag and handed it to Ye Yu.

"I told you, my swimming style is exactly a dime like yours, how do you feel when you look at your swimming style? The video may not be clear, but I showed it live, so you should see it clearly! Ye Yu said earnestly, when he competed in the morning, he felt that Fei's swimming style was not quite right, and he always felt a little unpleasant. But I can't say it.

"I feel so weird and awkward when I look at it." Fei began to think back to what he had just done, and he always felt that something was wrong. But after all, it's a move that has been practiced for so many years, and you can't find it if you want to find out what's wrong at once.

The door slammed open, and Ye Yu walked out with his short hair.

"I also felt that I couldn't speak, so I repeated the action in front of you, and you told me that you couldn't see it? Are you wasting my efforts? Ye Yu plucked Fei's ears in a huff.

Someone in pain covered his ears and screamed in pain.

This scene startled Mo Lin, who had just entered the door, was it abused?

Let go of her hand, Fei rubbed her red ears excitedly, how did her brother become so violent! I really don't understand the pity and pity the jade.

"Your movements are awkward from the moment you enter the water." Ye Yu sat on the bench and began to tie his shoes.

He stood in place in a daze and listened to Ye Yu's analysis.

"We all tried to rush into the water far from the water, and with the soft swing of the loach, we did win a few meters at the starting point, but! Our entry time is 0.01 seconds slower than others! ”

"Are you talking about the time spent in the air during the long jump?" Fei also thought about this problem, but after the experiment, she found that she was more sure that she would win her opponent in the long jump.

This idea was rejected by Ye Yu, "Our main purpose is not to surpass our opponents, we want to break our own records to challenge higher." Like your race, you overtook your opponent and won easily, but you didn't notice that your score was far from your record? Since we have the ability to guarantee that we can win, why don't we choose the method that can both win and guarantee that we can challenge our own record? ”

This made Fei a little surprised, why didn't she think of it? However, this has something to do with the fact that she feels like she is barely dancing when she swims!

"You're getting more mature in freestyle, but it's also getting heavier! I don't know if you found it yourself, but I found out anyway! Your morning game was a bit heavier than it used to be, and although you won, you don't feel good about yourself. Ye Yu's words pierced his heart, and he told all the questions that Fei thought about at noon.

That's right, she thought it was just her illusion, but she didn't expect it to be the case! She really had a problem swimming.

Ye Yu asked like a book: "What is the history of freestyle at the beginning?" ”

"It started in the early 19th century, when Australian R. Cavill used his legs alternately to hit the water, replacing the water clipping technique to achieve victory. In 1922, the American Wesmollo improved the use of alternating strokes with two arms and six alternating strokes with both legs to form a modern crawling mode. ”

Ye Yu nodded with satisfaction, that's right! Feifei's current movements are similar to the movements improved by the American Wismolo in 22 years, which will lead to regression of movements, and the swimming method that was originally labor-saving was felt by her swimming hard.

The basic technical characteristics of freestyle are that the human body lies prone in the water, with the head and shoulders slightly above the water surface, the torso rolls around the longitudinal axis of the body appropriately left and right when swimming, and the two arms take turns to stroke the water to push the body forward. After the hand enters the water, the paddling path is S-shaped, and the breathing is coordinated with the paddling action. As you paddle hard with your arms, use the current of water to inhale in the troughs that have formed on both sides of your head.

Its action structure is relatively reasonable, labor-saving, and low resistance, and it is the fastest swimming posture at present.

However, the specific explanation is that in the whole set of freestyle, the leg movements not only propulsion, but also play a balancing role, maintaining the stability of the body and coordinating the arms to do powerful strokes.

In the eyes of others, she may not be able to see where her problem is, but in Ye Yu's eyes, she can see at a glance where the problem appears.

Her arms struggled as she took turns paddling to push her body. Maybe it's not enough warm-up or maybe it's the wrong rhythm.

And her little trick of turning, where the real biggest mistake is wrong.

The secret of turning is the speed of turning, and the main factor affecting the speed of turning is the swimming speed before turning, if the swimming speed is too slow, it is difficult to turn.

When Fei turned around, the butterfly foot kicked the body to flex and flip, and then the reaction force turned the feet towards the pool wall, and finally the hands stroked down to accelerate the rotation speed. This test is how to overcome resistance in the water.

For Mo Lin, who has studied Fei Xiao's movements since he was a child, it is very simple to see the problem at a glance.

For the last stroke, place your other hand at your side and no longer roll from side to side, leaning down. When paddling to the bottom of your chest, bring your feet together and pull your legs together as butterfly feet. When pushing the water, lower the head and lower the body, put your hands close to your sides, then kick the butterfly feet, speed up the turn, bend the body, flip the palms of both hands downward, stroke down hard, and turn the speed. Flip your whole body, touch your feet against the wall, and stretch your hands forward.

Fei's problem is that he does not close his legs in time while closing his legs.
