breaststroke

—

breaststroke

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".

Jiadengshui

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.

stop

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

freestyle

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.

backstroke

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.

suggestion

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 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.

What should I do if medical resources are tight？ The National Health and Health Commission has taken four measures.

Source: CCTV news client

Recently, public opinion has reported that some places are short of medical resources and people have difficulty in seeking medical treatment. On December 14th, the State Council Joint Prevention and Control Mechanism held a press conference, and Jiao Yahui, Director of the Department of Medical Administration of the National Health and Wellness Commission, responded to the relevant situation.

Jiao Yahui introduced that in recent years, the demand for diagnosis and treatment of fever clinics has increased rapidly, and the contradiction between supply and demand is more prominent. However, the growth rate of medical service demand for general outpatient and inpatient services is relatively slow, and the utilization rate of corresponding medical resources is now in a safe and controllable range. The National Health and Health Commission has also taken a series of measures in view of the prominent demand for diagnosis and treatment of fever clinics and the rapid growth.

First, further expand the supply of medical resources and medical services. We require all hospitals above the second level and primary medical and health institutions to open fever clinics or fever clinics, and we have been vigorously promoting this matter recently. According to statistics, as of 12: 00 on December 14th, there were more than 14,000 fever clinics in hospitals above the second level in China, and more than 33,000 fever clinics or consultation rooms were set up in primary medical and health institutions. While increasing the number of fever clinics or fever clinics, we also further simplify the flow of fever clinics. The vast majority of patients go to the fever clinic mainly to prescribe drugs to treat COVID-19’s related symptoms, and many places have also set up simple clinics for fever clinics to further improve service efficiency. According to statistics in some places, the average time to see a fever clinic has been shortened from more than 4 hours at the beginning to less than 40 minutes. In addition, medical institutions in various places are also increasing the expansion and transformation of critical care resources in designated hospitals, sub-designated hospitals, and hospitals above the second level, as well as the increase of critical care beds in tertiary hospitals, the provision of equipment, the training of medical personnel, and the expansion and transformation of convertible ICU, all of which are in full swing. All 31 provinces (autonomous regions and municipalities) in China have formulated corresponding plans and arranged funds. These tasks are also in the process of promotion and implementation.

The second measure is to promote graded diagnosis and treatment. On the one hand, in cities, medical associations are used as carriers, and in rural areas, county medical associations are used as carriers to promote the graded diagnosis and treatment of COVID-19 and other medical services. Let the urban and rural tertiary networks and medical institutions implement their respective functional positioning. Health monitoring is mainly implemented at the grassroots level, especially the health monitoring and health management of key populations; Secondary hospitals provide technical support in all aspects of technology and manpower to meet the needs of general diagnosis and treatment; Tertiary hospitals focus on meeting the needs of diagnosis and treatment of critically ill patients. Through graded diagnosis and treatment, we build a reasonable and orderly medical order.

The third measure is to vigorously promote Internet medical services. Through Internet medical treatment, according to the diagnosis and treatment plan and the guide of home treatment, we will prescribe corresponding prescriptions for patients with COVID-19’s symptoms, and provide corresponding drugs through offline third-party distribution. At the same time, we also require medical institutions to provide 24-hour online consultation and medication guidance, as well as time-sharing appointment services. In this way, the instantaneous peak of medical institutions can be reduced, the gathering of people can be reduced, and the risk of cross-infection when people go to the hospital offline can be reduced.

Fourth, continuously optimize the process of fever clinic, general clinic and hospitalization. By optimizing the medical treatment process, it will provide greater convenience for the broad masses of people to go to medical institutions for medical treatment.

Jiao Yahui said that in the next step, we will further guide medical institutions at all levels in various places to continuously implement relevant measures, and use various methods and measures to expand the supply of medical resources and medical services to better meet the needs of the people for medical treatment.

The reason of C Ronaldo’s bleak evening scene： mistaking the platform for ability

C Ronaldo has gone far away to the desert, so that the hot sunshine in the desert can cure the injury and pain of the defeated plum ball king!

At the age of c, he has gone to the desert, and his competitive career has been finalized.

Although there is a lot of wealth, it seems to be happy! But its heart is painful!

As we all know, Ronaldo is aloof and arrogant, and I am the only one!

I take the super plum ball king as my responsibility all my life, and pursue honor, glory and data all my life.

C Ronaldo has been a technical career for more than ten years, and his money has been free and his wealth has been satisfactory; It cares more about face, scenery and honor.

During C Ronaldo’s career, during his years in Real Madrid, he won four Golden Globes and four Champions League games, which strengthened his confidence and courage, boasted himself the first, second and third place in the world, was extremely inflated and self-mad.

C Ronaldo’s greatest misfortune is to regard the platform as an ability! It is the real Madrid platform and personal efforts that have made its real Madrid years dazzling!

C Ronaldo left Real Madrid, moved to Juventus and Manchester United, accomplished nothing, and never won the Golden Globe Award, Sir, or the Champions League again! 16 lang in the Champions League every year! Its juventus years are incomplete!

C Ronaldo’s national team was ruined, and fans said that it was lying in the European Cup. Although it was exaggerated, it was not groundless!

C Ronaldo’s World Cup achievement is hands-free, which is a stain on his life! Causing 10 zeros in the World Cup to be bleak. Single-core team leader has the best score in the top 16.

After the dark years after Real Madrid, nothing was achieved after the World Cup.

C Luo Fang understands that it is the Real Madrid platform and Lafayette that have made its brilliant Real Madrid era. I mistook the Real Madrid platform for my ability, woke up like a dream, and wanted to return to Real Madrid and relive the beauty. But the vicissitudes of life, powerless, was rejected by Real Madrid! I have to go to Saudi Arabia to waste the rest of my life!

Life is like this, when you miss the opportunity, it may be a lifetime of regret and regret!

Guardiola： Arsenal are in an incredible state, but we are still competing.

Live on March 12 th, Manchester City 1-0 Crystal Palace, Manchester City coach Guardiola accepted an interview with Sky Sports.

Guardiola: "My experience is that it is very difficult for us to come here every time. When we came here, I always had a feeling that we played well, but we also had to think about the tenacity of our opponents. We are always fighting because we want to score more goals. They have’ weapons’, Zaha is there, Orlis, Ezer, and they have incredible threats. They have calm and outstanding offensive players, which is a matter of patience. They will delay time, so we must rush them. "

"Everything makes me satisfied, and we missed some opportunities to fight back. It’s not easy. They have six players defending in the penalty area, Harland has two guards and Gundogan has one guard. It’s a matter of patience. They are very tight on Harland. Alvarez is very important and we need him. We need him in midfield. He has some chances. Gundogan is an excellent player. He won the penalty and Harland did the rest. "

"After Cancelo left, we only had Walker and Gomez as full-backs. We had four central defenders, and the defense was very solid. All four of them are outstanding players, so we defended well. Of course, Arsenal are in an incredible state. We are still competing, Arsenal scored 50 points before. It was a typical winter game, a difficult game. We were there all the time, and then we won. Now we have to do everything, next Tuesday and Saturday, hoping to spend one of the best nights we have ever experienced at home, and we can do it again. "

Gao Zhidan： In view of the serious problems in the field of football, we are studying solutions and ways.

On the morning of March 12th, the first session of the 14th National People’s Congress held its fifth plenary meeting in the Great Hall of the People. After the meeting, the third "Ministerial Channel" interview was held, and some responsible persons of relevant ministries and commissions in the State Council were invited to attend the meeting.

A reporter asked Gao Zhidan, director of the State General Administration of Sports: Football, basketball and volleyball are deeply loved by the masses, and the development of the three big balls has attracted much attention from all walks of life. However, the current situation of promoting the development of the three big balls in an all-round way in China is not ideal. What do you think of this problem? What is the next work plan of the General Administration of Sports for revitalizing the three big balls?

In this regard, Gao Zhidan said that football, basketball and volleyball, the three major collective ball events, have a large population and great social influence, and are deeply loved by the broad masses of the people, especially young people. The results of the three big balls are not only the outcome of a game, but also the spirit of collectivism and patriotism.

Historically, China’s three major events, especially women’s events, have achieved good results in the world. China women’s football team once won the runner-up in the Olympic World Cup and was known as the "sonorous rose". China women’s basketball team won medals in the Olympic World Championships in 1980s and 1990s, and won the second place in the World Cup last year, showing a good momentum of continuous progress and development. China Women’s Volleyball Team, which has been tempered through hard training, has struggled from generation to generation, winning the world championship for ten times in three world competitions and winning honor for the motherland. Their women’s volleyball spirit of the motherland first, unity and cooperation, tenacious struggle and never give up, which is condensed by struggle and hard work, has inspired generations of Chinese people to make unremitting efforts to realize the Chinese dream of the great rejuvenation of the Chinese nation.

Gao Zhidan said, but realistically speaking, for a long time, the development of China’s three major sports, especially men’s events, was not satisfactory, and the level of men’s football was declining all the way. There were many chaos in the football industry, which was in sharp contrast with the requirements and expectations of the CPC Central Committee and the people all over the country. It is a sign of a sports power that the three major goals should be achieved, and it is also a short board that we must make up to speed up the construction of a sports power. Recently, in view of the serious problems in the field of football, we have been deeply rethinking and studying solutions and ways, and are prepared to systematically treat them from the aspects of ideological education, style construction, deepening reform, and doing a good job in the current work, so as to do a good job in all the work of the three goals in the spirit of re-taking the Long March.

Eight teams involved in the Super League were investigated for match-fixing, and the Shanghai seaport in Taishan, Shandong Province was among them.

Text/Jiang Shihua

At present, there is no definite time when the Super League will kick off in the new season, but the anti-corruption wave in China football triggered by Li Tie’s investigation shows no sign of abating. In particular, the news of match-fixing and gambling involved in the Xinghan Wu incident may not be an individual phenomenon. According to a well-known domestic football media source, as many as eight Chinese Super Clubs have begun to be investigated by relevant departments, among which the Shanghai Harbour in Taishan, Shandong Province is one.

Recently, a football media person surnamed M posted a message on social media that investigators had gone to Guangzhou and Jiaying to investigate the local gambling situation in the last two years. As we all know, there used to be four Super League teams in Guangdong, and the clubs in Guangzhou are Guangzhou City and Guangzhou Team. It is inevitable that one of these two teams will be investigated by the relevant departments this time. The Shenzhen team has been mentioned many times before. The most typical case is: in the 2019 season, the Shenzhen team drew 4-4 with Wuhan Zall at home, and the head coach of Wuhan team at that time was Li Tie, who is now in prison.

After Chen Xiaoyuan was investigated, because of his relationship with Chen Xiaoyuan, the Harbour Club is likely to be investigated by relevant departments. During Chen Xiaoyuan’s tenure as chairman of the Harbour Club, some accounts and other issues were the focus of investigation by relevant departments. Previously, the news of match-fixing involved in the Xinghan Wu incident made Shandong Taishan deeply involved. If nothing else, in the final stage of last season, Shandong Taishan team beat Shenzhen 8-0 at home, and this game was questioned by many fans. If it’s not a match-fixing, it’s at least a tacit match.

Mr. Mo Yan’s writing style is magical realism, so is China football?
