It is understood that this revision cuts through the management mechanism, visual image, programming and other levels and angles, and strives to bring more pleasing audio-visual experience and unprecedented content presentation to the majority of TV viewers.

  More professional, more focused, "produced by the front desk" and a strong attack.

  As the only national TV professional channel that broadcasts TV series 24 hours a day, CCTV TV series channel has presented countless classic plays to the audience since its launch, and has met the spiritual and cultural needs of the audience with endless masterpieces. In the brand-new revision of this launch, "produced by the reception desk" has become the most eye-catching brand logo.

  On October 24th, the night of the revision, the TV series "Passionate Years", produced by the Central Radio and Television General Station and co-starring Li Guangjie and Gao Lu, will be broadcast on the golden channel of TV series. As the first TV series produced by Headquarters, Passionate Years tells a touching story of Chinese researchers who took root in the Gobi and devoted their youth in the early days of the founding of New China. The unique theme, solid and beautiful storyline, accurately restored historical atmosphere and touching feelings of home and country made this masterpiece of main melody attract much attention and expectation, which triggered a warm response.

  It is understood that after "Years of Passion", many dramas produced by CCTV, such as "The Land of Hope" and "The Melody of Endeavour", will be broadcast in the prime time of CCTV. Taking the successful practice of this series of dramas as an opportunity, the TV drama channel will also launch more excellent masterpieces with good ideological, artistic and ornamental qualities.

  More youthful and fashionable, new packaging is stunning and blooming.

  Visual image design is very important for the establishment of channel brand image, which directly affects the competitiveness and recognition of channel brand communication. The brand new channel packaging of CCTV-8, which has won many heavyweight awards such as "Oscar Award in Packaging Industry" and PromaxBDA Asia Gold Award, and will be launched on October 24th, will promote the overall upgrade of brand visual system, with atmospheric style and distinctive features, which is more in line with the image positioning of world-class new mainstream media.

  The revised channel logo is based on a calm crimson background, which strengthens the color of CCTV-8 brand and brings positive energy to the audience. The concise and lively number "8" leaps to the top, and the organic integration of color and geometric numbers has a great aesthetic impression and makes people shine. It is understood that the design of the new LOGO of the channel is inspired by movie screens and home theaters. It has a three-dimensional sense and a sense of space, which will bring the audience a unique feeling of "sitting at home and watching movies".

  In addition to the stunning launch of the channel LOGO, multiple versions of ID deductive image propaganda films with different styles will further vividly explain the brand connotation of CCTV-8. Among them, it not only focuses on the communication of grand and heavy temperament, but also reflects the magnificent feeling of sunrise in the east; There is also a concise and lively expression of Chinese style, which brings a sense of elegance of flowers. It is both holistic and personalized, bringing refreshing visual experience and aesthetic enjoyment.

  More meticulous and accurate, new arrangement leads expectations.

  The TV series "National Children", which tells the touching story of the national children, recently ended in the top eight golden files of the Central Committee. According to the data of CSM National Network, the average audience rating of the drama is 1.22%, the average audience rating is 4.99%, the highest audience rating of an episode is 1.51%, and the highest audience rating of an episode is 6.48%, ranking first among the hit dramas in the same period. The Douban score of 7.6 fully shows the recognition and love of the audience and netizens for this work.

  After "National Children", the TV channel will also launch more masterpieces of realistic themes that show truth, goodness and beauty and highlight "small cost, great feelings and positive energy". Among them, Gina, a popular flower, starred in the war drama "The Unveiled Sunshine", which will be broadcast as "The Years of Passion".

  The family drama "I’m afraid it’s too late" led by Tang Zeng, the 2018 national viewing champion "Mother’s Uncle", is also gaining momentum, which makes people full of expectations.

Review the high-tech in previous Olympic Games.

  As the Olympic Games in Rio de Janeiro, Brazil are coming, I would like to review the history and see which scientific and technological products that appeared in previous Olympic Games are still in use today.

  2000Sydney 2008 Olympic Games

  1.shark skin like swimsuit

Shark skin 1.jpg

  For the first time in the Olympic Games, Australian star Thorpe won three gold medals in this swimsuit. Many swimmers try to enhance their competitiveness by using a "shark skin" one-piece swimsuit with a V-shaped back. Because according to the manufacturer of this swimsuit — — Speedo claims that it can increase the speed of swimmers by 3%.

  2.Trait racing suit

  Marion Jones in the United States and Cathy Freeman in Australia and other sprint stars use special running clothes developed by Nike. This kind of running suit is very sleek and has a hood, which can cover all parts of the sprinter except his face, hands and feet. This can keep the muscles warm and compress, and improve the sprinter’s performance.

  3.Recycled products sports equipment

  Steve Moneghetti, an Australian marathon runner, took part in the competition wearing shorts and vest made of recycled soft drink bottles. According to the manufacturer Nike, this material is cooler than other fabrics.

  Olympic 100-meter champion Donovan Bailey put on special running shoes made by Adidas. It is said that this special running shoe has a hard metal plate, which can keep human toes as stiff as jaguar’s claws when running.

  2008Beijing Olympic Games in 2008

  The 2008 Beijing Olympic Games adopted a large number of world-leading new technologies, such as ground lifting stage, multimedia, ground LED system, command system, communication system and other dozens of high and new technologies, involving many fields.

  1.Digital lamp

  The Olympic rings rose slowly in the Bird’s Nest and flew into the vast night sky. China’s ancient painting and calligraphy scrolls slowly unfolded, showing the classical artistic conception of ink painting; On the ancient Silk Road, huge wooden boats braved the wind and waves — — These shocking visual effects are outlined by the gorgeous lights of the Bird’s Nest.

QQ screenshot 20160726145819.jpg

  At the opening ceremony of the Olympic Games, more than 600 competition lights in the Bird’s Nest were all abandoned, and Zhang Yimou chose its own lighting. Science and technology have entered the digital age, and the lighting effect has also transitioned to digital lights. This new lighting effect makes the scale and imagination of the stage effect of the opening ceremony of the 2008 Olympic Games to the extreme. Digital lights are used in the 2008 Beijing Olympic Games: PG lights, that is, high-brightness projection lamp. By using the principle of optical projection and high-brightness light source, the contents on the negative are projected to the ground in full color, which can form a very visual impact picture effect at night. In the performance of the opening ceremony, the large scroll that runs through the center of the venue and the evolution animation from ancient times to modern times are successively displayed on the scroll, all of which are projected to the center of the venue by this PG lamp after pre-production. The simplicity of black-and-white contrast of China ink painting, the splendor of western oil painting and the strong color of Impressionism are all presented by this high-tech technology.


  LED (Light Emitting Diode) is a semiconductor solid light emitting device, which uses a solid semiconductor chip as a light emitting material. When direct voltage is added at both ends, carriers in the semiconductor recombine to cause photon emission and generate light. LED can directly emit red, yellow, blue, green, cyan, orange, purple and white light.

  In the 2008 Olympic Games, LED was used to the maximum extent. The opening scroll is opened on a huge LED screen. The screen is 147 meters long and 22 meters wide. It is a huge platform with the highest scientific and technological content, with 44,000 LEDs on it. The light and shadow effects made by LED are closely combined with performances, which conjure up various patterns and introduce the audience into a fantastic world. After repeated tests, LED can completely stand the tests of stepping on by actors and flooding. Although the whole opening ceremony took a long time, the key technologies such as battery solved the energy problem of LED.

  3.Aluminum alloy material

QQ screenshot 20160726142026.jpg

  At the opening ceremony of the 2008 Olympic Games, a big hole was opened in the center of the stage, and a "earth" with a height of 6 stories and a diameter of about 20 meters slowly rose from it. Where is such a big "earth" hiding? It turns out that this "earth" is compressed underground first, that is to say, the spherical structure must be flexible. When placed on the ground, it is oval, and it will become spherical after being pulled up by the steel wire above.

  After the ball is lifted by the lifting platform, the actor needs to perform on the vertical surface of the ball, so it needs strong stability after lifting to ensure the safety and effect of the performance. This all depends on high-tech aluminum alloy photosensitive materials, which makes the "earth" flexible.


QQ screenshot 20160726142220.jpg

  At the opening ceremony of the 2008 Olympic Games, "birds" and "whales" flew and swam freely over the huge scrolls. How did these come about? It turns out that slide projection technology was used in the opening ceremony before, but this time, all kinds of multimedia equipment were used. It can use computers to digitize media information such as words, graphics, images, animations, sounds and videos, and then integrate them into a certain interactive interface, so as to create a bowl-shaped screen of thousands of square meters at the top of the Bird’s Nest, showing a clear picture of the whale swimming freely and expressing the harmony between man and nature.

  5.Digital ignition

QQ screenshot 20160726142818.jpg

  Twenty-nine huge colorful footprints made up of fireworks opened the curtain of the 29th Beijing Olympic Games, symbolizing that the modern Olympic Games is coming towards Beijing step by step and entering the Bird’s Nest. The lighting of these 29 big footprints is controlled by computer system and digital lighting is adopted. This technology can ignite all fireworks in a short time, ensuring that fireworks can cross 3.5 kilometers in just a few seconds. In addition, there are 22 launching points in the dragon-shaped water system next to the Bird’s Nest. After digital control by computer, all fireworks bombs can shoot into the sky one after another, making the fireworks look like a flying dragon. Although traditional fireworks are still used, after digital ignition, fireworks show different visual effects from the past.

  2012London 2008 Olympic Games

  1.Photographic robot

QQ screenshot 20160726153041.jpg

  Getty Images, the official photo agency of London Olympic Games, installed photographic robots in some Olympic venues, which can realize remote control and 360-degree rotation. According to the NBC report, "photographic equipment can be hidden in flashlights, rafters and scaffolding, and placed in and around the Olympic Games, which can play the most important role in places where photographers can’t reach because of distance and safety reasons."

  2.A more attractive voice

  It is reported in the Atlantic Monthly that most of the voices heard on TV during watching the Olympic Games are not true. Some sounds were not recorded at the game site, at least in this sense, it is not true. Some audio is recorded in advance under optimized conditions and then used for TV broadcast. The website of Atlantic Monthly also cited an example of the Olympic archery competition. An Olympic audio engineer said that the sound was based on the sound he heard in the movie Robin Hood. He used a special microphone to collect the sound on the ground between the archer and the arrow rake. It is said that this method produces a sound that no one can actually experience at the scene.

  3.Double runway

QQ screenshot 20160726154303.jpg

  The runway of the main stadium of London Olympic Games has adopted a brand-new surface, which means that track and field athletes do not need to wear spikes to participate in the competition. According to the BBC, "Other runways are designed with rubber particles on the top floor, which combines the traction and shock absorption. Different from the past, the runway designed by Mondo separates these functions into two layers. The bottom layer is padded, which can cushion and shock absorption, and the top layer is durable, which can maximize the skid resistance, adhesion friction and durability. " This design makes it unnecessary for athletes to wear spikes on the track.

  4.artificial limb


  South African athlete Oscar Pistorius, who has nicknames such as "Oscar Pistorius" and "the fastest legless man in the world", became the first athlete to use artificial limbs to participate in the Paralympic Games. After a controversy over whether artificial limbs should be allowed to participate in the Olympic Games, Pistorius used special carbon fiber artificial limbs to participate in the 400-meter and 4×400-meter relay races.

  5. Athletes who put data first

QQ screenshot 20160726154743.jpg

  London Olympic Games is a "digital Olympics". Many athletes use sleep tracking devices and motion capture systems to understand their physical condition more accurately. According to the Financial Times, some companies dealing in biometric instruments also deal with athletes to participate in data collection to improve the performance of gadgets.

  6.Virtual bicycle


  Although it is thousands of miles away from London, Australian cyclists have been training in London cycling track by using virtual reality technology. In a video of the Australian Broadcasting Corporation explaining the technology, it can be seen that cyclists are looking at a screen that looks like a video game, which is actually an environment that is completely simulated according to the London Olympic Road Cycling Stadium. Each training bicycle is fixed in the Australia Institute of Sport, but it is equipped with a screen, a GPS and some ranging tools. This system can also collect the training data of athletes, and the coach can clearly know their time-consuming, speed, energy and riding distance.

  7.start detection system

QQ screenshot 20160726160118.jpg

  Omega, the official timer of the Olympic Games, brought a new starting equipment to swimming and track and field events in London Olympic Games. The track starter is fully electronic for the first time. It is said that the technology in the 1970s required athletes to push the starting device 5 mm to start. Now, swimmers start to light up directly to show who is in the first place, who is in the second place and who is in the third place.

  8.Kick sensor

  Originally, the Olympic Games may cancel the Taekwondo competition, but technically recording the strength and accuracy of kicking may save the event. Zhao Zhengyuan, president of the World Taekwondo Federation, said in an interview: "I think Taekwondo will really benefit from technology, because it can ensure that medals will be awarded to the best athletes and will not be awarded to others because of misjudgment by the referee. This is an excellent opportunity for us to stay in the Olympic Games. There are few competitions with this technology, which will help to eliminate human errors in taekwondo competitions. "

  9.Digital housekeeper

  Being selected for the Olympic Games is not only a proof of strength for an athlete, but also a supreme honor. Can the organizers of the Olympic Games use the power of science and technology to help athletes concentrate on the competition and eliminate their worries in life? Atos, the digital partner of the London Olympic Games, did just that. Atos Company established an identity information system for nearly 15,000 athletes who participated in the Olympic Games and Paralympic Games. The athletes who were included in the system were equivalent to obtaining a certification label, which made it easier to obtain visas and a series of preferential policies. Atos Company has also compiled a supporting application, so that athletes can log in to their identity accounts through their mobile phones, tablets or computers on weekdays. The account will contain a lot of information including the competition schedule, training plan and competition results, which is equivalent to providing a "digital housekeeper" for each participant.

  10.Reduce the burden on runners


  As a space power, the United States has also applied its own space technology to the preparations for the Olympic Games. Shannon Rowbury, a well-known American long-distance runner, unfortunately suffered from an injury and her femur was damaged. However, with the help of space science and technology, she only rested for six weeks after diagnosis and resumed training. Robery uses a set of AlterG anti-gravity running assistant device, which allows the trainer to train with at least 20% of his own weight, and the physical burden of the athlete will be greatly reduced. The principle of this treadmill is to pump air into the air bag around the runner’s waist. When the air pressure in the air bag rises, the runner will be lifted and the weight load will be reduced. Athletes can reduce their weight by up to 80% simply by pressing the up/down buttons in the panel.

  11.Team overall data analysis


  For cyclists, the wind tunnel laboratory is their loyal scientific and technological partner. The data analysis in the wind tunnel laboratory can help athletes optimize training programs, adjust training methods, and improve their performance by using aerodynamic scientific and technological achievements. But for a long time, the analysis of wind tunnel laboratory can only serve an athlete on a personal basis. Researchers at Monash University in Australia have improved an experimental device used to test airplanes and cars, enabling it to collect data of athletes for analysis. More crucially, this machine has crossed the barrier of analyzing individuals before, and can analyze the data of the whole bicycle fleet at the same time. In this way, the coach can make a training plan for the whole team according to the analysis results and find ways to improve the team’s performance.

  12.Red BullXplan


  Although an athlete participates in the Olympic Games alone, he represents more than just him. Behind the athletes, there is a team of coaches who support his motherland and train for him. Lolo Jones, an American hurdler, participated in the Red Bull Project X. She once said in a video: "I’m not fighting alone". The video shows the whole team behind Jones: a coach, a director, a manager, a sports scientist, a coaching consultant and a physiology consultant. Such a rich and powerful work team is naturally not busy in vain, they use the most cutting-edge technology.

  The Red Bull X project uses a 3D digital analysis system, which can do many things that humans can’t. Plan X is divided into three parts — — Vicon 3D tracking system, optical measurement system Optojump Next and data acquisition tool Phantom Flex Camera. The three technologies complement each other, which can not only give a macro evaluation of athletes’ performance, but also disassemble every minute of training competition into countless tiny fragments for analysis.

  Jones’s team made 39 reflection marks on her body. With these marks, 40 Vicon T40S motion capture cameras capable of shooting 2000 frames per second will track all her movements. Optojump Next, an optical measurement system, will decompose every jump of Jones into contact time, flight time, height, hurdle rhythm, specific energy, specific power, total energy and total power. Finally, Phantom Flex Camera, a top camera capable of shooting 10,750 frames per second, will record Jones’ every minute with images.

  "If technology can help an athlete perform better, then this system can benefit everyone." Jones’s average hurdle time is 12.5 seconds, which she believes is largely due to the help of the team and technology behind her.

  13.Real time feedback device


  Good results in the competition will be cheered by the audience and graded by the referee. However, in training, how do athletes know their performance? Jonathan Green, composer, sound engineer and Gregory Sporton, dancer of the Visualization Research Unit at the Birmingham Institute of Art and Design in Birmingham, England, developed a feedback system called Motivepro. The original intention of this system is to provide real-time action feedback for dancers. Dancers are required to wear a series of sensors, and their movement information will be collected by Motivepro. Once the wearer’s physical activity exceeds the preset range, the vibrator in the device will vibrate to remind him.

  Mimi Cesar, a rhythmic gymnast, found that this system can also be applied to rhythmic gymnastics similar to dance. For rhythmic gymnastics, the synchronization of the team is particularly critical. Motivepro system can give a reminder when an athlete’s movements are out of step, and can also collect sports information for the coach to analyze. With this system to help train, will the cooperation of the whole team be more tacit?

  14.Brand-new pool take-off platform


  The 2012 London Olympic Games used a brand-new upgraded swimming pool jumping platform in swimming competition. The platform was designed and manufactured by Omega. Compared with the previous take-off platform, the progress is that it has an adjustable inclined pedal certified by patent, which makes the athlete’s hind legs bend into a 90-degree angle when taking off in a squatting manner, which is considered to be the most suitable take-off posture. The new take-off platform is also equipped with a brand-new sensing system. This sensing system can ensure that athletes can hear the whistle at the beginning of the game at the same time, which can effectively avoid unnecessary mistakes of athletes. At the same time, the newly upgraded swimming pool take-off platform in Shanghai is equipped with a signal light system called "Swimming Ranking Indicator". At the end of the competition, the swimming lanes that won the first, second and third place will be marked on the take-off platform by different light spots, so that the audience can see at a glance.

  15.Advanced drug testing equipment


  GlaxoSmithKline is at King’ s College next to the Olympic Park. S College) has set up The Science Centre to serve the Olympic drug testing. During the Olympic Games, the center worked 24 hours a day, monitoring more than 6,000 urine samples and blood samples every day. After each competition, all the medal winners and the remaining half of the randomly selected contestants enter the center for illegal drug testing. The tested samples are divided into two parts, A and B, and A is stored for eight years for future more advanced scientific and technological testing; B was sent to the drug testing center. The drug testing center can check 70 illegal drug ingredients in one test, and each sample will be tested here for a total of 240 illegal drug ingredients. It can be seen that the fair conduct of the Olympic Games has a strong technical guarantee.

  16.Electronic medical records


  General Electric (GE) Medical Company provided an electronic medical record solution for the 2012 London Olympic Games, which made it possible for doctors and athletes to make medical records accessible through the Internet. The electronic medical records covering more than 700 participants were made in 90 days after the countdown to the London Olympic Games. At the same time, GE Medical Company also installed medical diagnostic equipment in the Olympic Park as a supporting facility for the whole set of electronic medical records.

  17.Top medical logistics


  During the Olympic Games, more than 16,000 Olympic athletes and more than 6,000 Paralympic athletes living in the Olympic Village will be fortunate to receive top-level medical logistics support. The latest version of super-large magnetic resonance imaging instrument, ultra-high-definition CT instrument, wireless digital X-ray detection system, upgraded ultrasonic detector and ECG detection equipment specially designed for the Olympic Games provided by GE Medical Company have all opened the eyes of medical volunteers for the Olympic Games. These equipments will not be removed after the Olympic Games, and they will continue to serve in this land that bears cheers and sweat.

  2014Sochi Winter Olympics in 2008

  Snow making: snow cannon

  Snow making machine is a brand-new snow making system, which forms ice on an evaporator at -15℃ and sends it to ski slopes through cooled air. Due to the climate, Beijing and Zhangjiakou host the Winter Olympics, and a large number of snow making equipment will be used. Funa machine is not affected by climate, so long as it can keep a certain amount of water, it can make snow.

  At the Sochi Olympic Games, the venue was really unfortunate — — Sochi is one of the warmest regions in Russia. In order to ensure that there is enough powdery snow to support the competition, Russian organizers use snow cannons to shoot a large number of artificial snowflakes. According to the news released by The New York Times, about 230 million gallons of water were used to make snow in this competition, and the snowfall covered an area of about 1,000 football fields.

Nearly 200 candidates participated, and the Chinese Table Tennis Association’s level test was conducted in Zhuheng.

On December 17th, the eighth and ninth stages of the Table Tennis Level Test (Trial) of China Table Tennis Association were held in Zhuzhou and Hengyang respectively. Nearly 200 candidates from Zhuzhou and Hengyang took part in this test.

It is understood that in order to further improve China’s national fitness service system and comprehensively improve the national fitness service level, the Chinese Table Tennis Association has designed and developed a table tennis level rating test (hereinafter referred to as "rating test") based on the original standards such as "Standard and Evaluation of Public Table Tennis Technology Level" and "National Youth Table Tennis Level". It aims to provide more authoritative technical certification standards for table tennis fans in China and promote the comprehensive and balanced development of table tennis in competitive sports and mass sports in China.

Yue Xin and Wang Haiyang, the leaders of the two test sites, said that the level test does not limit the crowd, gender and age, and covers all ages from young children to adults. Through the evaluation of sports level level test, the level of table tennis fans can be quantified, thus further promoting the development of table tennis sports groups. The grade evaluation of young children’s age is an effective way to promote the integration of sports and education.

It is reported that the holding of these two level tests marks the official opening of the promotion of table tennis level test in Hunan Province, and the Hunan Table Tennis Association will intensify its efforts to promote and implement it for all cities and States in the province.

Detailed illustration of the basic standard swimming posture of "Life Home"

Via: network

Copyright belongs to the original author.



With a jingle, before explaining the essentials of breaststroke, I will introduce it to you: "Rower’s legs don’t move, close your hands and then close your legs, first extend your arms and then kick your legs, and then straighten up and float for a while." As you can see from the jingle, the hand moves before the leg. Be sure to close your leg after you stop, and then kick after you reach out.

Arm movement

1. delimit. Put your hands forward and tilt your palms at about 45 degrees (little finger up). Draw your hands outward and backward at the same time, and then bend your arms backward and downward.

2. Draw inside. The palm turns inward from the outside, and the hand drives the forearm to accelerate the inward stroke. The hands are close together in the chest from the bottom up (the hands are high and the elbows are low, and the elbows are under the shoulders) and extend forward.

3. Stretch forward. Stretch your hands forward (elbow straight). It should be reminded that the outward stroke is relaxed, the inward stroke is hard, the completion is accelerated, and the forward stroke is positive.

Complete coordination action

Raise your head for air when you row your hands outside, lower your head and hold your breath slightly when you row your hands inside, and kick and exhale when you stretch your hands forward.

Leg movement

Retract your legs

Bend your knees and retract your legs, keep your heels close to your hips, and slowly retract your legs behind your thighs, which can reduce resistance. At the end of leg retraction, the knees are shoulder width apart, the calves are perpendicular to the water surface, and the feet are near the water surface.

Turn your feet.

The distance between the feet is greater than the distance between the knees. The feet are everted, the toes are facing outward, the feet are facing the sky, and the inner sides of the calves and feet are aligned with the water, like the English letter "W".


In fact, it is the process of leg straightening (hip flexion and knee extension), in which the waist, abdomen and thigh exert force at the same time, and the calf and the inner side of the foot push the water at the same time, first outward, backward and downward, then inward and upward, just like drawing a half circle. Pushing the water outward and clamping the water inward are continuous, that is, pushing the belt and clamping it.

When the pedaling is completed, the legs are straight together, the feet are turned inward, and the toes are opposite. Don’t push the water too hard, but accelerate it from slow to fast. The pedal speed is the fastest when the legs are nearly straight and close together.


After the legs are together and straightened, they slide for a short time (1-2 seconds).



Swimming is a whole-body exercise, and the activities of any part are inseparable from the coordination of the whole body. On the surface, freestyle relies on paddling and kicking to generate propulsion. In fact, the role of trunk can not be ignored. First of all, the torso should maintain a certain degree of tension. If the waist is soft, the whole person is like a pool of mud. Secondly, the rotation of the body can effectively exert the strength of the large muscle groups in the trunk, reduce the resistance and improve the work effect.

There are many forms of complete cooperation in freestyle. Generally speaking, it is common to paddle twice, fetch water six times and breathe once.

Arm entry action

1. The entry point of the hand is between the extension line of the shoulder and the midline of the body, leading with the thumb and obliquely inserting the water.

2. After entering the water, the hands, elbows and shoulders continue to stretch forward to stretch the arms. With the rotation of the body, bend your wrist and elbow, and your arms catch water outward and backward; After the hand paddles to the lowest point, rotate the arm to paddle inward, upward and backward, and keep the paddling posture with high elbow and bent arm.

3. When the arm is perpendicular to the horizontal plane, take the lead, accelerate the water push, and turn the arm to paddle outward, upward and behind until the thigh side, and lift the elbow out of the water.

4. After the water comes out, the arm moves forward naturally and relaxedly through the air, keeping the elbow posture high. Then hand in front of the shoulder leading into the water, start the next action.

(1) The arm paddles underwater in a curved line. From the side, the stroke trajectory of the hand relative to the body is "S".

(2) There are three basic forms of freestyle two-arm cooperation: front cross cooperation, middle cross cooperation and back cross cooperation. This picture is in the form of front cross, which is easy for beginners to master.

One-arm stroke is an action that beginners should focus on. As shown in this figure, the left arm strokes, then the right arm can support the board. Generally, the leg draws water for about 10 times, and the arm paddles once. You can add breathing exercises when you master it to a certain extent. The specific number of groups and practice methods will be introduced in detail in teaching.

Whip kick in the leg

1. The kicking action starts from the hip, and the thigh drives the calf to make a whipping action.

2. Kick the leg upward from the corner. Start with a straight leg, bend your knees when your feet are close to the water, and lift your calves up so that your feet can get out of the water and then draw water down. At first, you can kick water with your straight legs, but your legs are slightly relaxed and don’t be stiff. Your legs will naturally bend under the pressure of water. The knee joint bends at an angle of about 130-160 degrees before the downward stroke, and the stroke range is about 30-40 cm. Stretch your feet (ballet feet) when you draw water, and don’t hook your feet.


backstrokeAlso known as backstroke, it is a swimming posture in which the human body lies on its back in the water. Backstroke includes back breaststroke and back crawl, because the face is on the water and breathing is convenient, but swimmers can’t see where they are swimming and are easy to go in the wrong direction. Backstroke is the only position in which an athlete starts in the water, and the others all jump into the water.

1. When the arm is paddling, the water comes out with the thumb ahead. When the arm is moved, the arm is perpendicular to the water surface and the upper arm is close to the ear. In the process of moving the arm, the arm rotates, and when entering the water, the little finger is inserted into the water ahead.

2. If the head position is 12 o’clock, the water entry points of both hands are at 11 o’clock and 1 o’clock. After the hand enters the water, paddle straight down.

3. The arm stroke should be coordinated with the body rotation, and the position difference between the shoulders is constantly formed.

4. The two arms are crossed in the stroke, that is, the two arms are always in opposite positions. When one arm is paddling, the other arm moves.

5, the head remains stable without swinging left and right.

Backstroke coordination

1. Although breathing is not limited, it is best to use rhythmic breathing, or to inhale when one arm is fixed. After all, there will be waves and splashes when paddling and moving in the water. Breathing at will is easy to choke water.

2. Keep a horizontal body posture. The trunk and shoulders rotate around the longitudinal axis with the arm movements, and one shoulder is always out of the water.

3. Generally, every stroke is 2 times, the legs are drawn 6 times, and the breathing is 1 time.

4, the legs alternately whip up and down to draw water. Draw water up quickly and forcefully, with your feet slightly turned inward and stretched straight, and your legs and feet naturally relax when you draw water down.

matters need attention

1. When moving the arm, the arm should not be too wide close to the body.

2. If the arm is easy to bend when moving, you can temporarily lead the water with your little finger, and then lead the water with your thumb after getting into the habit of straight arm.

3. Keep your body stretched, upright, and almost horizontally lying on your back on the water, as if lying flat on the bed with a short pillow under your head.


Backstroke legs should experience the thigh force, both lifting and pressing, and experience the feeling that the thigh drives the calf.

butterfly stroke

butterfly stroke

Butterfly stroke is one of the swimming events, and the butterfly stroke technique evolved on the basis of breaststroke technique. The butterfly stroke is the last developed stroke among the four competitive swimming strokes. Because its leg movements resemble dolphins, it is also called "dolphin swimming".

1. The hand entry point of butterfly stroke is on the extension line of two shoulders, leading with the thumb and obliquely inserting into the water.

2. After entering the water, stretch your shoulders and elbows forward, and grab the water outward, backward and downward with both hands along the curve. When your hands are shoulder-width apart, bend your elbows and speed up the stroke.

3. After the hands are separated to reach the maximum width, the arms turn inward, upward and backward, and keep the elbows bent when the arms are lifted. When your hands are under your chest or abdomen, the distance between your hands is the shortest.

4. The combination of breathing and stroke is also the key to butterfly stroke. When the arm finishes paddling inward, the head comes out of the water to inhale, and when the arm is moved, the head returns to the water. Remember two "before", that is, the head comes out of the water before the hand comes out, and the hand enters the water before it enters the water.

Butterfly stroke coordination

1. When the distance between the two hands in butterfly stroke is close to the nearest distance, the direction of arm stroke changes again, and it turns to outward, upward and backward strokes until the water comes out.

2. After paddling out of the water, the arm moves forward through the air under the drive of the shoulder. When preparing to enter the water, the arm moves forward from both sides in a low, flat and relaxed posture.

3. It is difficult to master the body posture of butterfly stroke, and it is also difficult to master the whip kick. When studying butterfly, we will have special decomposition exercises to let you master the operation step by step.

Matters needing attention in butterfly stroke

1. The stroke route of butterfly stroke is generally "keyhole" shape, which means that the distance between hands under the chest or abdomen is the shortest, and this stroke route before and after is relatively uniform.

2, pay attention to the butterfly limbs movement is both arms and legs at the same time coordinated force.
