Now Xu Jie's behavior is not the behavior of a real man, because he hesitated at such a dangerous moment, that's why Xu Chang was so angry in his heart.As Xu Jie's elder brother, Xu Chang certainly wants Xu Jie to become a real responsible man.

Seeing his elder brother was really angry.And the words became more and more severe, Xu Jie finally came to his senses, and he took out the Xiao Huan Dan in the jade bottle without hesitation.He swallowed it directly, and then said with a smile on his face: "Hey, big brother, the taste of this Xiao Huan Dan is really good, very fragrant, very appetizing!

If there is food now.I feel that I can directly eat the portion of three people, hehe.It seems that if my future nephew suffers from anorexia, then I just need to give him Xiaohuandan, hehe...! "

While Xu Jie said some words that could make people feel relaxed, he began to infuse the true energy in his body into Xu Chang's body without hesitation. Now Xu Jie is actively making up for the mistakes he made just now.

"Xiaojie, you...!" Xu Jie's funny action directly dispelled the anger in Xu Chang's heart. Facing Xu Jie with a rascal expression, Xu Chang was speechless. Who told Xu Jie to be his younger brother? , as an older brother, he has to think about his younger brother.

"Xiaojie, let's forget about this time, but you have to remember in the future, if you encounter the same thing again in the future, no matter how precious things are on you, but in front of your own life, These things are scumbags. You don't want to lose your life for something outside your body, such a person is definitely a real fool, Xiaojie, do you understand?"...

Although Xu Chang forgave Xu Jie's irrational behavior just now, Xu Chang still seized every opportunity to educate Xu Jie.

"Well, big brother, I understand. Don't worry big brother. After learning this lesson, even if I want to forget it, I will never be so confused again in the future."

"Well, that's good, that's good." Xu Jie's words finally made Xu Chang feel relieved, and then Xu Chang continued: "Little Jie, hurry up, big brother, I'm going to start speeding up!"

"Understood, brother, I've already caught up, you speed up!"

"Okay, let's go...!"

"Wow...! Wow...! Wow..." The sound of swimming on the surface of the sea became louder and louder, and Xu Chang's swimming speed suddenly accelerated a lot. Gradually, Xu Chang distanced himself from Leng Xin and the others... …

............................................................................................................ ..
His eyes turned to Leng Xin, and the time went back to 10 minutes ago. After Leng Xin listened to the monkey's persuasion and stopped chasing the two brothers Xu Chang and Xu Jie, Leng Xin and the monkey began to be very careful and approached slowly. Brothers Xu Chang and Xu Jie, moreover, as soon as they approached Xu Chang and Xu Jie at a distance of about 150 meters, Leng Xin and Hou Zi were no longer close.

As long as Leng Xin and the others keep this distance from the two brothers Xu Chang and Xu Jie, coupled with the cover of the sea water, the two brothers Xu Chang and Xu Jie will not be able to find Leng Xin and the monkey.

That's why Xu Jie tried very hard to observe the movement behind him afterwards, but he still couldn't see Leng Xin and the monkey.

"Huh...! This distance is almost the same, big brother, let's keep this distance. With such a long distance, plus the cover of sea water, the two brothers Xu Chang and Xu Jie in front will not be able to find us. Big brother, what do you think? Sample?"

The monkey exhaled heavily. Just now they were about 300 meters away from the two brothers Xu Chang and Xu Jie, and they swam 150 meters away in the sea, and the two brothers Xu Chang and Xu Jie in front were still swimming continuously.Therefore, Hou Zi and the others shortened the distance by 150 meters, which really took some effort from Hou Zi and Leng Xin.Now the monkeys are a little out of breath.

"Well, let's do it this way. I didn't expect swimming to be so tiring. This short distance of 150 meters is actually more tiring than the one hour I used to swim in the river. Swimming is really not an easy thing. ah!"

Leng Xin is also a little out of breath now, so.Leng Xin didn't even think about it when he heard the monkey say that it was almost the same.He immediately stopped chasing Xu Chang and Xu Jie.The few minutes of high-speed swimming just now really exhausted Leng Xin.

"Huchi..., Huchi...! That's right, big brother. Swimming is really not an easy thing. If I hadn't learned martial arts, my physical strength has increased greatly, and I have also learned some swimming skills from you, big brother. Now I am definitely down, I can't catch up with brothers Xu Chang and Xu Jie at all. And if I can't catch up with brothers Xu Chang and Xu Jie, then the result...

Hehe..., a swimming that looks simple, but I can't imagine that there is so much knowledge in it.It seems that no matter how simple things are faced in the future, as long as I don't master them.Then I'd better be careful lest the boat capsize in the gutter. "

The monkey answered Leng Xin in agreement, and was panting heavily. It was obvious that the monkey had exhausted all its strength in the high-speed swimming chase just now.

Indeed, Leng Xin and Hou Zi were right.Swimming seems to be a very simple thing, it seems easy to master.Many people think that swimming is just a few strokes with hands and feet, and no effort is required at all. However, if you really think this way, then you are wrong. In fact, swimming is not easy.

Swimming is the skill of floating on the water by oneself and moving forward in the water with the movements of one's own limbs.

Swimming can be divided into competitive swimming and practical swimming. Competitive swimming is the second largest event in the Olympic Games. It includes four strokes: butterfly, backstroke (also known as backstroke), breaststroke and fast stroke (also known as crawl/freestyle). racing events, and synchronized swimming.

Swimming is one of the sports that men, women and children alike like.Ancient swimming, according to the textual research of existing historical materials, the more consistent view at home and abroad is that it originated from the ancient people who lived in rivers, rivers, lakes and seas.

In order to survive, they must catch water birds and fish as food in the water. By observing and imitating the movements of fish, frogs and other animals swimming in the water, they gradually learned to swim.

China has a long history and vast waters.Swimming in records began more than 5000 years ago, but it is only in recent decades that swimming has developed as a sport.

In the 30s, swimming appeared in major cities in England one after another.

In 1837, the first swimming organization was established in London, England, and the earliest swimming competition in England was held at the same time.

In January 1869, the Federation of Metropolitan Swimming Clubs (now the predecessor of the British Amateur Swimming Association) was established in London and formally fixed swimming as a special sport.And then spread to each colony of England, and then spread all over the world.

History and Development Since ancient times, swimming has been one of the most important survival skills, whether it is for hunting, escaping from beasts, or encountering a shipwreck to save oneself.

As far back as 2500 BC, there was a similar freestyle event in ancient Egypt.

The huge bath built by the ancient Romans was also a place for the upper class to swim and socialize in their spare time.

Swimming in the early days was only regarded as an important part of the education of noble children and soldiers' training. It was not until the end of the eighteenth century that swimming became a popular activity when the time and opportunities for the working class to participate in swimming increased.

There are not many classifications of swimming, which are mainly divided into three types: practical swimming, competitive swimming, and synchronized swimming.

Practical swimming: Swimming that is more valuable in military, production, and life services is called practical swimming.Such as crawling (freestyle), breaststroke, sidestroke, diving, treading water (standup), water ambulance, armed swimming, reverse breaststroke (backstroke).But there are also all kinds of synchronized swimming, which is extremely challenging for people's lung capacity

Competitive swimming: Competitive swimming refers to swimming events that have specific technical requirements and are competed in accordance with the rules of swimming competitions.Swimming has been included in the official Olympic Games since the first Olympic Games (1896).

It can be divided into two categories: competition in swimming pool and competition in open water.Such as freestyle, breaststroke, backstroke, butterfly (also known as dolphin stroke) and individual medley swimming composed of these four types of swimming.And relay swimming competition swimming.

Competitive swimming is mainly based on speed to determine the ranking. It is conducted according to the national swimming competition rules and is called competitive swimming.

Competitive swimming originated in England and the country of kangaroos.Later, it was introduced to other countries. From the middle of the nineteenth century to the beginning of the twentieth century, swimming competitions around the world began to become common, and swimming associations were established one after another.

The British Amateur Swimming Federation (formerly known as the Metropolitan Swimming Federation) was established in 1869 and was the first National Swimming Federation to be established.Between 1850 and 1860, there was an international swimming competition between England and Kangaroo.

当国际奥林匹克运动会于1894年6月16日在巴-——黎成立时，游泳已被列为1894年的奥运项目之一。至于国际业余游泳联会（fina）。则成立于1908年。

Synchronized swimming: Synchronized swimming is also known as "artistic swimming".It is a competitive sports project that integrates dance, gymnastics, swimming and other projects.Arrangements are very demanding.

It is divided into single, double, and collective events.Through the movement of the athletes' limbs on the water surface and the music, it shows various graceful movements and artistic skills of various shapes, which greatly enjoys the masses, so it is known as "water ballet".

Swimming styles are generally divided into crawl, breaststroke, butterfly and backstroke.Crawl is the fastest.The breaststroke stroke is more graceful, the butterfly stroke is the most explosive, and the backstroke saves the most energy.

Freestyle: Kangaroo countryman Wei Lishi used a swimming style with his hands moving forward in the water in 1850, which can be regarded as the prototype of butterfly stroke.In 1873, the British national swimmer John John Trajan adopted a swimming style that used chest swimming legs and then alternately crawled forward with both hands. -I also created a kicking method of "shallow kicking" based on the swimming style of Trajan and Alexandra.

Since then, the kicking of the legs has only changed slightly, which is freestyle.There are many forms of complete coordination in freestyle swimming, and it is generally common to use 2 strokes per stroke.Kick water 6 times, breathe 1 time.

Breaststroke: Breaststroke is a swimming style that imitates the swimming action of frogs, and it is also the oldest swimming style.During breaststroke.Swimmers can conveniently observe whether there are obstacles ahead and avoid hitting them.

In the mid-18th century, breaststroke was called "frog stroke" in Europe.

Due to the relatively slow speed of the breaststroke, it was not as fast as the other strokes in freestyle competitions (freestyle swimming without prescribed posture) in the early 20th century.Make breaststroke technology be excluded.Subsequently, the FINA stipulated the swimming style, and breaststroke technology was able to develop.

Backstroke: The early backstroke was simply floating on the water on the back.Then push forward with a breaststroke kick.

At the Olympic Games in 1900, swimmers began to use their hands to move their heads forward on the surface of the water. The pedaling kick did not begin to appear until the 1912 Olympics.

Butterfly stroke: The rowing method of butterfly stroke was first used in the breaststroke competition in 1926 by aher, a swimmer from the country of tanks. At that time, he still used the kicking method of breaststroke.

After the 1952 Olympics, the International Amateur Swimming Federation (fina) decided to separate this style from the breaststroke, thus adding the butterfly stroke and allowing swimmers to use the dolphin kick.

Swimming has great exercise value and she improves the cardiovascular system.

Swimming plays a very important role in improving the cardiovascular system. The stimulation of cold water can promote blood circulation through heat regulation and metabolism;
In addition, the pressure and resistance of the water during swimming also play a special role in the circulation of the heart and blood. When swimming on the water surface, the water pressure on the body has reached 0.02-0.05 kg per square centimeter. Large, changes in physical conditions, the pressure will increase, the speed of swimming will also increase the pressure load, the muscle tissue of the atrium and ventricle can be strengthened, the capacity of the heart chamber can also gradually increase, and the number of heart beats reduce.

In this way, the activity of the heart can be saved, but the whole blood circulation system can be improved. Under the resting state, the diastolic blood pressure increases and the systolic blood pressure decreases, so the blood pressure value becomes more favorable; the elasticity of blood vessels is also improved.

According to the statistics of relevant experts, the average person’s heart beats about 66-72 times per minute in a quiet state, and the stroke output is about 60-80 milliliters. However, people who have participated in swimming for a long time only need to contract about 50 times under the same situation. The output per stroke reaches 90-120 ml.

Swimming can also improve the lung capacity of the human body.

The breathing of the human body mainly depends on the lungs, and the strength of the lung function is determined by the strength of the respiratory muscle function. Exercise is one of the effective means to improve and increase lung capacity.

According to measurements: when swimming, the chest of a person is subject to a pressure of 12-15 kilograms, and cold water stimulates muscle contraction, making it difficult to breathe, forcing people to breathe hard and increase the depth of breathing, so that the amount of oxygen inhaled can meet the needs of the body.

一般人的肺活量大概为3200毫升，呼吸差（最大吸气与最大呼气时胸围扩大与缩小之差）仅为4—8厘米，剧烈运动时的最大吸氧量为2.5——3升/分，比安静时大10倍；
The lung capacity of swimmers can be as high as 4000-7000 ml, the breathing difference can reach 12-15 cm, and the maximum oxygen uptake during strenuous exercise is 4.5-7.5 liters per minute, which is 20 times larger than that at rest.Swimming promotes the development of human respiratory muscles, increases chest circumference, increases lung capacity, and opens more alveoli when inhaling, allowing smooth ventilation, which is extremely beneficial to health.
