Zhang Jingtao remembers that when the earth was not alarmed, he often went to the swimming pool to swim when he was a teenager, and he often met this kind of coach.

For this reason, once he finally couldn't help but ask, why can't children learn to swim with their heads up? He also asked why he didn't hold his child's chin and let him learn to swim with his head up.

The coach replied very professionally: "This is an international standard swimming technique, not a wild way, and supporting the chin will dislocate the child's neck bone, which will be life-threatening, please understand...... Do you know this, sir, about the international standard swimming style? The one you're talking about doesn't count as swimming. ”

What? Not considered swimming?

Zhang Jingtao was stunned and stammered.

For this reason, when a little girl who wanted to participate in the swimming project of the high school entrance examination and needed to swim 50 meters in 1 minute and 20 seconds was scolded by the coach because she did not swim well, and punished her for practicing by herself, Zhang Jingtao went to inquire.

Because he believes that children should be taught to swim according to their aptitude, not everyone can use the freestyle method with strong feet without cramping.

As soon as I asked, this little girl's question is really a common problem for almost all novices.

The problem with this little girl is:

First, if you use freestyle, your feet are easy to cramp, usually you can't swim the prescribed 50 meters, and your calves will cramp, and although her explosiveness is good, her endurance is too bad, and she can't break out for 10 meters, and the more she swims, the slower she swims, so even after a lot of training, she is likely to not get a full score because she doesn't play well enough, or her feet cramp, or even choking on water;

Second, if you use breaststroke, the movements are always uncoordinated, the angle of the leg kick is always not right, although the ventilation is no problem, but the speed is not enough.

For this reason, her two swimming styles exceeded 100 seconds, and she did not expect to get a perfect score of 5 sports points.

But in the high school entrance examination, even 1 point is not bad.

Of course, this little girl can change to sprinting, but although her sprinting speed is acceptable, she is not completely sure of the full score, starting a little slower, the state is a little worse, you may miss the full score, in fact, once you learn to swim, it is more secure.

This little girl has been working hard for most of the summer.

For this reason, after Zhang Jingtao heard this, he taught the little girl a wild way that is not considered swimming.

That is, a breakup, a kick, a head up, do most of the breaststroke action, to breathe, and then, a sinking head, when swimming with a stuffy head, put both hands in front, like a shuttle breaking the waves, with a freestyle swing under the feet, that is, another half of the freestyle foot stroke.

Then, as soon as I broke up, I kicked my legs, and I looked up, and it was a very natural breaststroke ventilation.

After a second pause, his hands stretched forward again like a shuttle, and half a freestyle came under his feet.

In this way, you can use a short freestyle swing to speed up, and you can use the breaststroke to lift your head to breathe easily, and in the process of breaststroke lifting, let your feet kick your legs, so that the tendons can be relaxed to the greatest extent, so as to avoid foot cramps.

Moreover, Zhang Jingtao also taught her that when she swims with her head bored, she can count it herself, and you can swing your feet eight times, if you think that eight times is not as good as ten times, then count ten times to see which one you adapt to, after all, if you can do it well, it must be faster than eight times, and even the number of ventilation will be reduced.

For this reason, when the little girl was suddenly ill and rushed to the doctor, she actually listened to Ye Luzi's words, and practiced according to Zhang Jingtao's teaching, and as a result, as long as these two movements were done smoothly once, they would be very smooth and could continue to do it.

After these two movements are connected, the main driving force is of course freestyle, but in the case that she can swing her feet 10 times, she can swim 2.5 meters in one breath, or even more than a little.

In other words, in the entire 50 meters, she only needs to change 19 breaths, and even if she plays well, she only needs 18 breaths.

So, half an hour later, when the coach took another mock test, the little girl not only swam 59 seconds in the 50-meter distance, but also was extremely relaxed.

When the swim was over, I only took a few deep breaths, and my breath relaxed, and I was simply calm.

Zhang Jingtao has no doubt that if she trains more, she can improve her speed a lot, but that's it, she is already ranked first among all the students taught by the coach, 6 seconds more than the second place, and although the second place is good because of her physical talent, she will not have foot cramps when she uses freestyle, but after swimming, she is simply panting like a dog, and, more importantly, the second place is a boy.

Undoubtedly, the coach immediately stepped forward and began to reprimand the little girl, and he reprimanded her for a long time.

Then, Zhang Jingtao saw that the little girl was learning the international standard swimming style again.

Of course, there is no doubt that after meeting Zhang Jingtao for the second time, the little girl immediately came to talk to Zhang Jingtao.

Zhang Jingtao taught her to swim with her head up.

Teachings, wild paths, chin support.

Of course, according to the coach, supporting the chin will dislocate the child's neck bone, because the person thinks that the chin support is to support the weight of the child's whole person, so the chin has to bear hundreds of pounds of weight.

In this regard, Zhang Jingtao was speechless, in fact, when supporting the chin, the child will definitely not receive more than ten catties, which is very safe.

If this is a problem, then the child will take a nap with his chin on the table and his head will fall off!

Because his head and the strength of his body are definitely more than ten catties.

As for why the support force used to support the chin is not more than ten catties, this does not need to be proved by calculating a complex buoyancy formula.

It's because ordinary people stretch out their arms and hold weights on their hands usually don't exceed ten catties.

It can be said that after straightening your arms and holding a ten-pound dumbbell piece in your hand, those who can hold it for ten seconds are people who often train to carry weights, and girls usually can't lift this weight.

Therefore, the trick to chin support guidance is to keep your arms as straight as possible to ensure that the strength used in your hands is safe.

Of course, chin support can only be used on beginners who already have experience in boring head swimming and standing up for ventilation, otherwise it will naturally be ineffective.

And this little girl, although in the coach, still learn international swimming, but yesterday, has come to the swimming pool with her family to train a wild road, has had more than an hour of enthusiastic practice, this is the second time, for this reason, as long as you master the body buoyancy of the head swim, learn only in a moment, so she easily learned to swim head up.

In this regard, the little girl's family was really surprised and excited, and even the little girl was a lot more confident, feeling that she could really do anything as a good student.

And self-confidence, on the contrary, is the motivation to learn, very important, can her family not be excited?

Of course, they knew what had happened before.

They glanced at the coach over there with contempt.

My daughter is Xiu, and they all have this sentence written on their faces.

Xiu, which is the pronunciation basis of the bird language show, comes from the famous Suzhou embroidery since ancient times.
