Fei shook his head, not everyone has the same swimming method, Mo Lin has been training in track and field all these years, and the strength of his legs and arms has naturally increased. In contrast, Fei is not very good at butterfly swimming, so it is better to let Mo Lin challenge.

In fact, Fei took a fancy to the initial strength of the backstroke, and she could increase her speed through the posture of her rotation and return trip, so she changed the swimming type with Mo Lin.

"Are you sure? I feel dangerous, too. Tingting also felt that something was not quite right.

"Otherwise, Fei Fei and I will make a comparison according to the previous method and then according to the current method, which one takes less time, and I will choose which." Mo Lin was lying on the edge of the pool, don't be so troublesome!

I don't know what the three of them said, so they looked at each other a few times and nodded.

"Get on the board! Get ready! The white tiger cheered excitedly, he hadn't seen the performance of the "Double Rain Combination" that had caused a sensation in the sports world for n years, and he was finally able to feast his eyes and be so happy that he exploded.

The starting board is not a standing jump, but a five-meter jump.

The two of them got on the 10-meter-high platform and began to mutter, facing away from everyone, Ye Yu couldn't see what his lips were saying.

After a while, the two of them walked five meters from the edge of the high platform and took the lead.

"Is the girl taking the lead?" Isn't it Molin's who has always taken the lead?

"When the time comes, I don't know if the game will be started by the men or the women, let Mo Lin come first." Ye Yu shook his head, there is no requirement for men or women to jump first in the tacit match, and the majority obeys the minority.

On a high platform

Mo Lin jumped on the spot several times and began to jump, four of them crossed to the border, and used a little force to bounce to make the body bounce up naturally.

The 360-degree knee bend and rotation of the body for 3 weeks reduces the pressure of the body, so that the body does not have an impact force at the moment of contact with the water.

The "U" body begins to move forward to do the butterfly stroke and begins to glide 50 meters into the first 50 meters.

Fei Xin stood calmly on the high platform with his eyes closed, and his body showed a relaxed posture.

Mo Lin's butterfly swimming posture is the same as Ye Yu's, but it is completely different.

Ye Yu's butterfly swim belongs to the category of dolphin swimming, but Mo Lin's seemingly dolphin is not.

As you swim, the torso parts and the head constantly change their relative positions to each other. The head and torso are sometimes exposed to the surface of the water, and sometimes they dive into the water, forming an undulating position in the form of waves.

With the horizontal axis waist as the center, the torso and legs make rhythmic swings, and the force is on the waist and abdomen. Then use the thighs to drive the calves, and the two legs together do an up and down whipping motion. These movements are closely linked to the movements of the head and arms, creating a wave action that is characteristic of butterfly strokes, so there is less resistance from the body when moving forward.

"Brother Yu! It's all butterfly swimming, how do I think Mo Lin's swimming style is not quite the same as yours! Are there two other ways to swim butterfly? Yu Xin asked curiously, she saw Mo Lin swimming butterfly for the first time.

When the legs are finished in the previous stroke cycle, the feet are at the lowest point, the knee joints are straightened, the buttocks are raised to the surface of the water, and the hip joints are flexed to about 160 degrees.

Then the legs are straightened and moved upward, the hip joint gradually expands, and the hips sink When the legs continue to go up, the thighs begin to press down, the knee joints press down with the thighs, the movements bend naturally, and the thighs continue to accelerate downward.

As the degree of knee flexion increases, when the foot is raised close to the water, the hips drop to the lowest point, and when the knee joint is bent at an angle of about 110-130 degrees, the foot is lifted up to the highest point, and the water is accurately lowered behind the water.

When the foot is drawn down, the ankle joint is relaxed, the foot is straightened, and then the calf and calf accelerate back and down with the thigh. Continue to accelerate your feet down and move your thighs upwards again, and when your knees are fully straightened, the downward strokes end.

The butterfly leg is performed by the waist force, through the hip, knee, and ankle joints, and in harmony with the trunk and spine movements. The direction of movement of the foot is downward and backward, and its downward amplitude is greater than that backward

When pushing up and lifting, the knee joint must be straightened, and if there is a slight bending, the back of the calf will create a lot of resistance. Also, when lifting your leg upwards, don't push too hard to reduce resistance. The focus of the leg hit should be on the downward stroke, and the speed of the leg down should be about twice as fast as the upward leg lift.

The only thing they have in common is that they both use their arms and legs to push themselves forward.

Because of the diving from the high platform, Mo Lin went to the pedal board to send himself out of the power at the beginning, so he had to change the posture of the butterfly.

And this action doesn't even seem to have been seen much by him!

(Bunny Tips:

I apologize to Baidu here, and most of the many swimming skills in this book are reproduced in Du Niang. Once again, solemnly explain, reprinted in Du Niang, don't be surprised. ）

It's a butterfly position, but it's not counted.

The stroke of the butterfly arm is the main factor in the propulsion and is relatively large compared to other positions. The butterfly arm stroke involves entering the water with both arms in front of the head and making a curve stroke along the sides of the body. When the two arms are drawn below the shoulders, the angle of the lower arm and the upper arm is about 90-100 degrees, when the two hands are drawn under the abdomen, the distance between the two hands is the closest (almost together), and then the transfer to the water pushing action, when the two hands are close, the hands do an arc to push the water outward.

"His movements are more mature than mine." Ye Yu sighed, although he was mature, it was not suitable for him! This technique is too much arm strength, and the fly in the ointment is that this swimming method is not suitable for everyone, and it is easy to mislead beginners.

"Then you can try him and see if he can improve?"

Ye Yu shook his head, he couldn't try! This set of actions is too substitutional, and if one is not careful, it will take his original foundation crookedly and regress.

After Mo Lin holds the water into the water, the hands and forearms continue to rotate externally and enter the water holding stage. When holding water, his hand moves in the direction of outward – backward – downward. With the external rotation of the forearm, the palm turns from the outside back to the back and then enters the stroke phase.

When the arm enters the paddling phase, the forearm and palm are the main face of the stroke. Flex your elbows so that your elbows are in a higher position. The external rotation of the forearm and the gradual increase of the flexion of the arm are performed at the same time, when the arms are drawn below the shoulders, the angle of the lower arm and the upper arm is about 90-100 degrees, and when the two hands are drawn under the abdomen, the two hands are closest (almost together), and then switch to the pushing action.

Ye Yu said this action......

Can't do it!

The arm strength required is really strong! There will be no way to practice for a while, maybe that's why Fei has to change his swimming method with him!

I apologized to Du Niang again, and reprinted the text on the skills......
