How many swimming positions are there in swimming?

Everyone knows that swimming is very good for people’s health, and many people are keen on swimming now, so in this case, everyone has done some research on swimming. Many people are looking for their favorite postures when swimming in school, but they don’t know much about the specific and separable postures. Here are some specific introductions about swimming.

freestyle

One of the swimming events. In 1896, the first Olympic Games began to be listed as an official event. Freestyle is not limited by any posture, crawl is the fastest, and crawl has become the only posture of freestyle. Crawling is like crawling, that is, paddling with both arms alternately and kicking with both legs alternately. This kind of swimming posture has reasonable structure, small resistance and even speed, and it is the fastest and most labor-saving swimming posture in the world at present.

The basic technical characteristics of freestyle are that the human body is prone in the water, with its head and shoulders slightly higher than the water surface. When swimming in, the trunk rolls around the longitudinal axis of the body appropriately, and the arms take turns paddling to push the body forward. After the hand enters the water, the paddling route is S-shaped, and the breathing and paddling movements are coordinated. When the arm paddles hard, use the water flow to inhale in the valleys formed on both sides of the head.

breaststroke

Breaststroke is an ancient swimming style. According to records, as early as 2000 ~ 4000 years ago, China, Rome and ancient Egypt had similar swimming styles. On August 24th, 1875, the famous swimmer M Webb swam across the English Channel in breaststroke, which lasted for 21 hours and 45 minutes. In the early 19th century, breaststroke was the first position adopted in swimming competitions. However, due to the slow speed of breaststroke, there are fewer and fewer people who swim sideways, crawl and use breaststroke in the competition. It was not until the third Olympic Games in 1904 that breaststroke was separated from other postures.

butterfly stroke

During the period from 1924 to 1936, the biggest innovation of breaststroke was that after the stroke, the arms were no longer moved forward from the water, but the arms were moved from the air but the legs were still clamped by breaststroke, and the deformation of breaststroke-butterfly stroke appeared. In butterfly swimming, the body lies prone in the water, and relies on the powerful strokes of the arms and the wavy strokes of the legs to push the body forward. There is no fixed body posture.

backstroke

One of the swimming events. In 1900, the 2nd Olympic Games began to be listed as an official event. Backstroke includes backstroke and crawl backstroke. Reverse breaststroke is the earliest backstroke, which is similar to breaststroke in action and opposite in body posture. That is, the human body lies on its back on the water, and its arms paddle backwards from the head to the side. In the first few Olympic Games, the backstroke was held in an anti-breaststroke position. When backstroke, the body lies almost horizontally in the water, the chest naturally stretches in line with the abdomen, the head is submerged in the water, and the face is exposed to the water. When swimming in, the head always maintains an upright posture, and the trunk naturally rotates around the longitudinal axis due to the alternate paddling action of the two arms.

How many swimming positions are there in swimming? Different postures in swimming bring different exercises to different parts of people’s bodies, because everyone knows that swimming can exercise all parts of people’s bodies, so swimming is very good for everyone to exercise healthily.

Football match

Wonderful moment

In a football training class, we played a match between grade four and grade three.

Before the game, the coach said to us, "We should not score three goals in 15 minutes in the fourth grade, and if we finish, we will run ten laps in the third grade." "yeah!" Our fourth-grade players cheered up, not only to win the game, but also because the match was much more interesting than constantly training with the ball and passing the ball.

The confrontation began. First of all, Wang Yike, a fourth-grade student, served the ball to Xu Zimo. Xu Zimo just dribbled the ball forward, and Wang Wenxuan snatched it away in an instant and passed it to striker Zhou Yuxiao, who ran to the penalty area with the ball. When I was about to hit the door, I seized the opportunity and shoveled a ball at Zhou Yuxiao with lightning speed and successfully took it out. Then I quickly got up and passed the ball to Li Jiaming.

It’s a pity that I forgot to stare at people. Xia Shaozhong grabbed Li Jiaming’s ball while I was not looking. However, Li Jiaming is not a vegetarian. He stepped forward with a big foot and drove the ball to the door. Next, in the third grade, Zhou Yuxiao took the ball and ran. Sun Yuanhao riveted his strength and didn’t keep it. The ball scored. Unfortunately, there are only five minutes left, so it seems difficult to score two more goals in the third grade.

As soon as several teammates in our fourth grade came together, they decided to fight a protracted war with them next. It was our turn to serve. Forward Wang Yike passed the ball to Li Jiaming. Li Jiaming provoked the ball and drove it forward hard. The third-grade goalkeeper Chen Ganyu blocked the ball with an accurate side jump and threw it out.

Chen Ganyu threw it to Xia Shaozhong, and Xia Shaozhong passed it to Zhou Yuxiao. Wang Yike took the opportunity to successfully grab the ball, but unfortunately he didn’t keep it. The ball fell to Wang Wenxuan’s feet again, and Wang Wenxuan passed it to Zhou Yuxiao to hit the door and was caught by our fourth-grade goalkeeper Sun Yuanhao.

Next, we have to fight back. I took the ball across the center line to find Li Jiaming and passed it to him. Li Jiaming was ready to hit the door, but unfortunately he didn’t score. At this time, the whistle blew and we achieved our goal.

This wonderful match tested our skills and made the cooperation between teammates more tacit.

Football is really a passionate sport!

Score: 101-93! Shandong women’s basketball team won again and won the third place in the CBA Summer League in Yumin Division, Xinjiang.

In the second quarter of the game, Shandong narrowed the score to only 3 points by 4-0. Qingdao is very powerful and has always been in the leading position.

Italy’s 17-year-old striker has attracted the attention of many giants, but he was given up early in AC Milan.

Born in 2006, Caprini, a young Italian striker, has performed well in various competitions this season and has scored nearly 20 goals so far. His rich potential and excellent finishing ability have attracted the attention of many European giants such as Juventus, Atlanta, Paris Saint-Germain and Barcelona, and he intends to throw an olive branch to them this summer.

Caprini, who is currently playing for the Fiorentina Youth Team, joined the youth training system of AC Milan in 2015. Unfortunately, it was not long before the attacker with Italian, French and Guinean ancestry was considered unable to gain a stable foothold in the team, and was officially abandoned by the Rossoneri in 2017.

However, the player didn’t give up his efforts. Later, he moved to Novara, Entella and other teams to prove his strength. Last summer, he was able to join the well-qualified Fiorentina youth team, becoming the top scorer in the U17 youth team, and once again realized his football dream. With his excellent performance, he has also been called up by the Italian youth team, and his development prospects are promising.

Perhaps AC Milan will feel a little regret after seeing the development of Caprini. However, at that time, the Rossoneri were in the most turbulent time of the team, not only the record of the first team was erratic, but also the club did not have much energy to invest in the training and construction of the youth echelon. With the entry of Elliott Group and Hong Niao Capital, they have paid more attention to finding outstanding young players, and many outstanding young talents have emerged in the past few years.

Colombaud and Nasti are the best young shooters trained by AC Milan at present. The former is being loaned out to Maleche, which is promoted to Serie B, for exercise, while the latter has officially entered the stage of the adult team in Serie B team cosenza this season, both of which have played well. The younger Kalmada is also growing steadily, and they are expected to wear the first-team shirts of the Rossoneri in the future and go into battle at the San Siro Stadium.

Great 2-3! Although Zhang Linyan was defeated, she scored three consecutive goals, which was praised by China fans: Messi Corridor.

A great score of 2-3 was born in the first leg of the semi-final of the Swiss Women’s Super Playoff which ended on the 21st. China teenager Zhang Linyan’s Cao Meng women’s football team narrowly lost to the defending champion Zurich women’s football team. In this campaign, although Zhang Linyan, a teenager from China, suffered a glorious defeat, she started to play and scored a full moon machete goal, and scored three consecutive goals. In this regard, China fans praised and commented: Messi Corridor!

When it comes to talented teenager Zhang Linyan, it can be described as a blockbuster. In the women’s Asian Cup final at the beginning of last year, Zhang Linyan came off the bench in the second half like a god. At that time, the China women’s football team was 0-2 behind the South Korean women’s football team and was in a dilemma. With the help of Zhang Linyan’s miraculous feat of making a point and scoring a header, the China women’s football team finally achieved a 3-2 turnaround and won the championship!

Since then, Zhang Linyan has continued to climb to the peak of her career and joined the Swiss giant Grasshopper Football Club on loan. Seeing that a season is coming, Zhang Linyan’s overseas performance is too amazing, and her goals and assists in various events have been in double figures or close to double figures. This is undoubtedly a mythical existence for a rookie studying abroad!

What’s more, at the previous overseas awards ceremony, Zhang Linyan, as a China player, won the Swiss Super Golden Globe Award and the Golden 11 Best Team Award, which is really a envy of others.

In the two key rounds of the Swiss women’s super-playoff final, Zhang Linyan continued to break out, and scored twice in a row, bypassing the goalkeeper and pushing the empty goal, and finally successfully helped the Cao Meng women’s football team win 3-0 and 1-0 in a row, and advanced to the semi-finals with a total score of 4-0.

Zhang Linyan’s performance in Switzerland is like an elf, especially her erratic dribbling skills at her feet, which is unpredictable and often makes her opponents unpredictable. Even in the face of burly Swiss defenders, Zhang Linyan can still find ways to get out of the way and score long-range shots. In addition to using the technical dribbling at the foot to score, Zhang Linyan scored two world waves in the Swiss Women’s Super League before, and was also successfully elected as the best goal in two rounds of the league.

Cao Meng’s women’s soccer team lost 2-3 at home to defending champion Zurich in the first leg of the Swiss women’s super playoff semi-final in the early morning of 21st. In this campaign, although Zhang Linyan, a teenager from China, was defeated, she made her debut and played the whole game. In the 67th minute of the second half, she made a long-range arc with the lateral cut of the dribble under her feet. It’s amazing!

After this campaign, Zhang Linyan created another miracle, and made her debut in three consecutive Swiss women’s super playoffs+played the whole game+scored goals, which was incredible! It can also be explained that the Swiss Women’s Super Golden Globe Award previously awarded is not a talented teenager Zhang Linyan!

After the game, Swiss Grasshopper Football Club issued a document praising Zhang Lin Yan, saying: Zhang Linyan scored again! In the first leg of the semi-final of the league playoffs on Saturday night, Zhang Linyan scored a wonderful long-range shot with her left foot in the second half. Unfortunately, Cao Meng women’s football team lost 2-3 to Zurich women’s football team. Come on in the second round next weekend!

The comment area below also attracted many comments from China fans. One fan from Zhejiang praised Zhang Lin, saying: Wonderful, this is Messi Corridor, and I would like to call it Pippi Corridor in the future!

How do you evaluate Zhang Linyan’s crazy and amazing performance overseas?

Asia-Africa World Cup competition: the group advanced and the number of semi-finals tied, and Africa won by one advantage.

In the history of the World Cup, the bipolar status of Europe and South America is unshakable. At present, all the World Cup champions come from these two regions, while teams from other continents, not to mention winning the championship, have not even stepped on the final venue yet. Relatively speaking, Asia and Africa are relatively close. There are more countries in both continents, and the number of World Cup places is similar. Africa has five and Asia has 4.5. That is to say, if Asian teams are lucky, winning the transcontinental play-offs will make the number of Asian and African teams in the World Cup the same.

So, who has the better World Cup performance in Asia and Africa in history?

Of course, we don’t need to calculate the total score or total goal data of all Asian teams and African teams in history, just look at the results of key nodes. Specifically, look at the teams on two continents, the number of times the group advanced, and the best results.

In these two aspects, Asia and Africa actually tied.

Historically, both Asian teams and African teams have been promoted 11 times. Of course, it needs to be said here that Asia in football refers to the AFC, so Australia is also counted as an Asian team.

Let’s list the specific situation below. In the history of the World Cup, African teams promoted by the group included Morocco in 1986, Cameroon in 1990, Nigeria in 1994, Nigeria in 1998, Senegal in 2002, Ghana in 2006, Ghana in 10 years, Nigeria and Algeria in 14 years and Senegal and Morocco in 22 years. A total of 11 times.

As for Asian teams, Japan has four times, South Korea has three times, North Korea and Saudi Arabia each once, and Australia twice. It happened to be 11 times. I am ashamed to say that this data, if Australia did not join the AFC from Oceania, then Asian teams actually lagged behind African teams.

Let’s look at the best results. Originally, South Korea reached the semi-finals in the 2002 World Cup and won the fourth place, which was once the unattainable achievement of second-rate teams such as Asia and Africa. But FIFA World Cup Qatar 2022 and Morocco have also achieved this. And to tell the truth, Morocco, the fourth place, is more convincing than South Korea in those days. Everyone knows this, and there is no need to start talking about it.

Therefore, in terms of the best results of the World Cup, Asia and Africa also tied.

So, which side of the world cup is better? There is a data that Africa is dominant, and with this data, we can say that African teams have higher ceilings and stronger ability to work miracles than Asian teams.

In fact, the data of the previous group promotion times is very general. After all, reaching the top 16 and reaching the top four are both group qualifying, but the gap between these two results is not small. So we might as well break it down again-the number of times we scored in the top eight.

In this regard, Africa is far better than Asia. Because Cameroon in 1990, Senegal in 2002 and Ghana in 10 years all reached the quarterfinals of the World Cup, and the number of quarterfinals was three times. What about Asia? It is still zero.

It should be noted that in the 1966 World Cup, North Korea reached the quarter-finals, but at that time, the World Cup was only 16 teams. Therefore, the quarter-finals of North Korea should be strictly called the first round of the knockout round, but it is actually the same level as the next sixteen. You know, Cameroon, Senegal and Ghana reached the second round of the knockout round, so North Korea, the quarter-finals, is not included in this data.

In today’s scale, reaching the quarter-finals means that the group will go further than the group. If it’s a miracle to beat the Asian and African teams into the knockout stage, then the miracle of the quarter-finals is certainly higher than the miracle of the quarter-finals. In fact, if we take away the controversial semi-final result of South Korea in 2002, we will find that the upper limit of Asian teams in the World Cup is not high, and the best result so far is the first round of elimination. So at this point, there is still a gap between Asian teams and African teams.

Of course, judging from FIFA World Cup Qatar 2022’s performance, Asian teams seem to be better than African teams. I hope there will be an Asian team in the future that can break through the long-standing ceiling.

Fabiano suggested that Rishalison consider a strong Serie A team, and Cristiano Ronaldo faded out of the mainstream.

Rishalisson complained that he had too few chances to play at Tottenham Hotspur. Although the Brazilian star apologized to Kong Di, people felt that his personality was not suitable for the top teams in the Premier League. Fabiano, a former Brazilian star, also wants his younger generation to consider other leagues. Apennine football is suitable for players with this personality. Fabiano suggested that Rishalison should consider the strong teams in Serie A, both Milan and Rome need strikers. As Serie A is developing, the arrogant players can choose Italian football. Of course, fabiano also advised Risalesson to lower his salary standard. Although the Brazilian star has a strong personal ability, his career is in a state of "no progress".

Can Cristiano Ronaldo consider the mainstream league? The goal efficiency of Portuguese superstars in Saudi Arabia is still very high. Many people expect Cristiano Ronaldo to return to the five major leagues in Europe, and fabiano also discussed this topic-Cristiano Ronaldo has faded out of the mainstream. Although the Portuguese superstar is still in excellent condition and his influence is still the same, it is almost impossible for him to return to the mainstream teams in European football. At the beginning of Ronaldo’s victory in Riyadh, mainstream sports channels were still paying attention to his movements. However, judging from the mainstream media such as Team Newspaper and Kicker in March, there is less and less content about Cristiano Ronaldo in sports, which is a sign that he has faded out of mainstream sight.

When Rishalison came to Tottenham, people had high expectations for him, because he could play on the wing or in the middle, taking into account the roles of Sun Xingyu and Kane. Fans who have seen FIFA World Cup Qatar 2022 know that Rishalison has a strong personal ability, and his goals are usually ornamental. He also praised the younger generation for combining the advantages of South American players and European players. However, Risalesson did not show his comprehensive quality in the top teams in the Premier League. Fabiano felt that there were two reasons that prevented Risalesson from developing his potential under Kong Di. The first one was injury. His injury on the eve of the World Cup disrupted his development plan in this club.

Most players will increase the probability of injury in the Premier League. After all, the big clubs in English football have high competition density and fierce confrontation. If Risalesson can choose a strong Serie A team, the schedule of Apennine Club will be less intensive, which will effectively alleviate his injury. Furthermore, although the thickness of Tottenham’s lineup is not very good, there is no shortage of wingers in Kong Di, and Sun Xingyu and Kulusevski are still ahead of Rishalison. Although Rishalison is still qualified for the front waist, after Lucas Jr. returned from injury, Rishalison’s playing opportunities will be reduced.

Others talked about Rishalison as Kane’s replacement, and fabiano also told the truth-in Brazil’s tactical mode, Rishalison has no problem as a center. However, Kong Di’s system needs a No.9 player with strong fulcrum and a strong sense of grabbing points. Obviously, Lisa Song’s style can’t be rotated with Kane, so it is better for him to change teams. Judging from the overall situation, the requirements of top teams in Serie A for strikers are not so complicated, and Risalesson can give full play to his potential. Moreover, fabiano said that the strong Italian football teams have a rising trend in the Champions League, AC Milan has entered the quarter-finals, and Inter Milan has a high probability of advancing to the next round.

Serie A has gradually separated from the category of "pension league", which is also something that Risalesson needs to consider. After the ball, the author thinks that Lisa Song is very similar to Anthony in some aspects. They both like to show off their skills and show off their skills. The platform of the Premier League is more rigorous, especially the strict manager like Kong Di, who can’t tolerate the mistakes of his players. It can be seen that fabiano suggested that Risalesson consider the top teams in Serie A, and this suggestion has some truth. Regarding whether Cristiano Ronaldo can return to the mainstream, some time ago, Chelsea’s striker couldn’t score, and some people suggested that Burleigh reconsider the Portuguese superstar. After all, Cristiano Ronaldo’s ability to seize opportunities is ok.

As the Blues gradually recovered in these games, no one suggested that Burleigh and winstanley consider Cristiano Ronaldo. As for other strong teams, they have no financial resources to introduce Cristiano Ronaldo. After all, his salary requirements are too high, and no big club is willing to face so many locker room storms. Therefore, C Ronaldo faded out of the mainstream. In fabiano’s view, the cooperation between Cristiano Ronaldo and Mendes ended, which also led to the end of the Portuguese superstar’s career in the mainstream league. After all, Mendes has a good relationship with the major teams, and Cristiano Ronaldo has lost his interpersonal relationship in the mainstream football.
