What to buy for football: a professional guide helps you find the best choice.

Football is the most popular sport in the world, and it has a broad mass base, whether as a leisure or professional competition. If you are a football fan, or you just want to play football in your spare time, it is very important to choose a good football. This article will provide you with some professional guides to help you find the best football.

1. Material: The material of football is mainly divided into leather and synthetic materials. Leather football is usually more durable and feels better, but the price is also higher. Synthetic football is cheaper, but it may not be as durable as leather football. You need to choose the right material according to your budget and frequency of use.

2. Size: The size of a football is usually marked by its diameter. Generally speaking, the diameter of a standard match ball is 21.5 cm. However, for beginners, it may be better to choose a bigger football because it can help them control the ball better. If you are an adult or a teenager, you can choose a smaller football.

3. Weight: The weight of football is also very important, because it will affect your performance in the game. Generally speaking, the standard football weighs about 410 grams. If you often train for a long time, then you may need to choose a heavier football.

4. Brand: There are many well-known football brands in the market, such as Adidas, Nike and Puma. These brands of football have certain quality assurance, but also have their own characteristics in design. You can choose a brand according to your personal preference and budget.

5. Price: The price of football varies greatly, ranging from tens of yuan to hundreds of yuan. Although the higher the price, the better the quality of football, but you don’t need to spend a lot of money to buy a good football. Generally speaking, 100-200 yuan football is enough to meet the needs of most people.

6. Test: Before you buy a football, you’d better try it yourself. You can try a few kicks on different courts to see how the ball feels. In addition, you can also ask your friends to try it and listen to their feedback.

Generally speaking, it is not difficult to choose a good football. The key is to choose according to your own needs and budget. I hope the above suggestions can help you.

What’s the difference between aerobic exercise and anaerobic exercise? Which is easier to lose weight?

Hello, this is China. Now everyone attaches great importance to physical health, and exercise has also been put on the agenda. There are two words in exercise, whether you understand them or not, but they will not be unfamiliar, that is, aerobic exercise and anaerobic exercise.

What is the difference between aerobic exercise and anaerobic exercise?

I don’t know how you understand these two words. Many people think that aerobic exercise is exercise with less oxygen consumption. Some people even think that aerobic exercise is mainly responsible for reducing fat and anaerobic exercise is responsible for gaining muscle. Is that really the case? What is the relationship between them?

In fact,The difference between these two exercise modes is that the metabolic mode of providing energy is different.Aerobic exercise mainly provides the energy needed for exercise through aerobic metabolism. Correspondingly, anaerobic exercise naturally refers to the exercise mode that provides energy through anaerobic metabolism.

It sounds like a clear line, but in fact, aerobic energy supply and anaerobic energy supply rarely exist independently. Often, a variety of energy supply methods work at the same time, so what we call aerobic or anaerobic exercise is only differentiated according to the main energy supply methods.

Aerobic vs anaerobic, which is easier to lose fat?

In fact, anaerobic exercise, like aerobic exercise, has a good fat-reducing effect. Fat is the energy reserve in our body. As long as we consume energy, we naturally consume fat. Just,Aerobic exercise and anaerobic exercise consume different periods of energy.

Aerobic exercise mainly consumes energy during exercise, while anaerobic exercise will continue to consume energy after exercise and reduce the possibility of energy being converted into fat.Therefore, from the perspective of energy consumption, anaerobic exercise and aerobic exercise actually consume the same amount of fat.

From the point of view of shaping, anaerobic exercise also has many benefits. Many people are afraid of anaerobic exercise to train themselves into thick legs and shoulders, which is completely worrying. Although anaerobic exercise has the effect of strengthening muscles, it is by no means possible to build a big size by lifting iron casually in your spare time. Moreover, with the increase of muscle content, our own basal metabolism will also rise, and the body consumes more energy, which is more conducive to our fat loss.

Exercise can really lower blood pressure, and the research has been hammered! 3 kinds of exercise, especially suitable for patients with hypertension.

Hypertension is one of the most common metabolic diseases, and most patients suffer from it. On the one hand, it means taking medicine for a long time or even for life. On the other hand, in life, they need to regulate their own lives and adjust their daily behavior, and then they are subject to many restrictions.

However, in order to control blood pressure and stabilize the disease, these things have to be done, and they must be adhered to in order to get healthy. As for the methods of lowering blood pressure in daily life, most people will think of exercise, but few people know whether exercise can lower blood pressure and how to lower it.

Can exercise lower blood pressure? Look at the answers given by scientific research.

Here’s one for everyone first."reassuring":

Getting into the habit of exercise does have a stable antihypertensive effect.

according toAberdeen Thai university of dundee, UKThe comparative experiment conducted by the research group shows that conveningMore than 6000 elderly people with hypertension were treated.People, after a series of moderate and high-intensity exercises such as pedaling bicycles and jogging,Blood pressure dropped by about 9% on average..

According to the researchers’ further discovery, the tension of the autonomic nervous system is reduced due to the acceleration of metabolism during the exercise of the elderly.catecholamineThe amount of release is reduced, soBlood vessels will also expand reasonably.With the increase of vascular capacity, blood pressure naturally decreases.

Not only that, exercise can also make the bodyMuscle fibers thicken, which in turn makes blood vessels more elastic., can withstand the negative effects of hypertension and reduce the risk of complications.

It can be seen that exercise does have the effect of lowering blood pressure, but although exercise is good, it is not appropriate to take the wrong method, such asExcessive exercise, the choice is not suitable for their own physical fitness.Sports events, etc., on the contrary, it is easy for your bones and muscles to be consumed and worn, increasing injuries and hidden dangers of diseases.

Therefore, for friends who want to rely on exercise to lower their blood pressure, it is very important to choose their own exercise methods. Here are three kinds of exercises recommended, which are especially in line with the physiology and condition of patients with hypertension.

Want to lower blood pressure through exercise? Try these three kinds of exercise.

The first kind: running or jogging.

Running should be the simplest and most obvious exercise mode, as the mostClassic aerobic exerciseExercise intensity is moderate, and it can effectively enhance the body’s blood oxygen content, further improve blood quality, and play a better role in lowering blood pressure.

Of course, running also needs to pay attention to "degree". Generally speaking, patients with hypertensionRun about 1 km to 3 km every day.That is, greed is easy to burden knees and muscles.

The second type: light and moderate resistance exercise.

What is resistance movement? Simply put, it is a way of exercise that will impose a certain burden or oppression on the body, such asDumbbells, sandbags, push-ups, etc, all belong to the typical resistance movement mode.

However, some studies have found that proper resistance exercise canReduce the activity of vagus nerve in patients with hypertension,Down-regulating the sensitivity of peripheral sympathetic nerveTo reduce vascular resistance.Therefore, proper circulatory resistance training has also been written into the guidelines of the European Heart Association in 2020.

The third kind: cycling

Simply put, cycling is one of the typical endurance sports methods.Adjust the leg shape, strengthen the muscles and body shape., has a very good effect.

At the same time, cycling can also play a good role in lowering blood pressure. While riding a bicycle,Because of breathing and wind pressure,The frequency of oxygen we breathe will increase,Increased blood oxygen content. Therefore, the blood circulation in the heart will also be accelerated, which will strengthen the heart and maintain blood pressure.

Not only that, according to research, riding a bike often, justPrevent nerve aging and osteoporosisIt can also help.

To sum up, for patients with hypertension, it is absolutely right to exercise regularly. Choosing the exercise method that suits them best, arranging life plans scientifically and reasonably, controlling blood pressure and stabilizing their condition are actually things that are easy to grasp.

English League Cup: Manchester United vs Newcastle United! If you don’t rotate, you will collapse? Newcastle are afraid to give up the cup

Let’s have our first chat today.United Cup: Manchester United vs Newcastle!

However, Manchester United has been very poor recently, and the Internet is full of posts about Teng Hager. Last season’s "Teng Sheng" and "Da Ming" have become "Teng Hi" and "Incompetence".

But Newcastle’s crisis may be even bigger. If Eddie Howe doesn’t handle it well, it may become the next Berlin League.

The Berlin United we talked about yesterday was overwhelmed by two-track operations, causing a lot of injuries, and then both strength and morale collapsed.

Newcastle haven’t collapsed yet, and it’s still the sixth place in the Premier League, but it may be soon.

Now they have a lot of injuries, Xiao wine made a simple picture, Isaac, Boatman and other six main or semi-main players will come back at the end of the month as soon as possible.

With so many injuries, what has caused a situation?

Last time they played Wolves, there was no striker on the bench.

There are 9 people on the bench, but they are almost all goalkeepers and defenders, with only two midfielders and none strikers.

Moreover, the two midfielders, Willock and Ritchie, are in poor condition. On the one hand, they are weak. On the other hand, they have only played 53 minutes in the Premier League this season, and they are very lacking in competition.

This is actually a terrible thing-A team that plays on two fronts in the Champions League and Premier League has no reliable strikers and midfielders on the bench.

So we can see that against Wolves, Newcastle only changed one person … There is really no one to change.

This is very dangerous.

You know, playing Dortmund on the 26th is a tough battle, and it costs a lot. And the number 29 wolvesIt rained heavily.,The physical consumption of rain fighting is greater.

Newcastle played two high-intensity games in these four days, and the starting lineup actually changed only one injured Isaac! Wolves have only changed one substitute to play!

You know, their starting lineupThe average age is 29.2 years.! Very old! Their game style is still fierce and easy to get hurt.

Today’s game against Manchester United is the third game in eight days. If Eddie Howe dares to fight again, if one or two people are injured again, I’m afraid it will become Berlin United.

Of course, even if they want to fight,I’m afraid these main players can’t fight any more.

In the last game against wolves, their performance was very poor.

Yes, I did get two, but how did these two get in?

The first one was that armand traore, the Wolves’ midfielder, knocked over his goalkeeper, selling half and giving one to Newcastle.

The second was to give Newcastle a controversial penalty.

Although Taylor gave the penalty the first time, from the VAR replay, Schell was suspected of diving, maybe not a penalty, but also to Newcastle Huang Ka.

On the contrary, wolves have more opportunities here, such asNeto has unlimited military training on the side, Bourne.

Bowen is not weak, of course, but you should know that as the tallest giant defender in the Premier League, the full-back who played this season is very physically exhausted. The third consecutive game is still a rainy battle. How can he get the physical strength to defend Neto?

If Neto hadn’t been injured by accident, I’m afraid Wolves would have entered.

On the other side, Trippier is also terrible-only two of the 11 confrontations were successful, with a success rate of 18.2%.

Trippier, a first-class defender, was beaten so badly, mainly because he was too tired. After all, a 33-year-old man played the whole game twice in four days, which one can hold up?

If Newcastle can’t stand the wolves’ strong flank, then why play Manchester United today?

Manchester United and Rachford, these wingers, are better than Neto Huang Xican, right?

The pressure on Manchester United is too great, and it has been sprayed all the time. The last Manchester derby made people hang easily, and it was even worse.

Tenghage is different from Eddie Howe.

Eddie Howe can bring Newcastle to this height, and there is no need to worry about prestige, class crisis and so on.

But Tenghage should consider these. If he loses again, can he still convince the public? Will class be over? These are really hard to say.

Therefore, Newcastle can not fight, just stay and play the League and the precious Champions League. Even if you want to play the domestic cup, there will be a more important FA Cup. What is the British Cup? Tottenham Hotspur, which fights on a single line, rotates greatly.

But Manchester United really have no retreat. For them, victory will be more important than rotation.

Therefore, although the recent situation is worse for Manchester United, Manchester United really needs a victory.

On the Newcastle side, what Eddie Howe needs most is the health of the players. As for the British League Cup, the priority may not be too high.

Although the strength of the two sides is close, the gap in fighting spirit may be huge, and in the chicken rib cup, fighting spirit may be more important than strength, for example, Wolfsburg played Leipzig yesterday.

All things considered, can Manchester United satisfy the fans? What do you think? The cocktail party will look forward to their victory.

Well, in other competitions today, Xiaojiu will still send you text analysis in the evening. If you have anything unclear, you can ask me, "Look at the ball and see clearly", and we will be there or not!

If you like it, move your fingers and pay attention to it!

Do you know all the cold knowledge about World Football Day?

World Football Day

These world cup cold knowledge

Do you know all about it?

Although the cold winter is coming, the football enthusiasm has not diminished. Tonight we will have a wonderful match between Croatia and Brazil, and today is the World Football Day recognized by the United Nations. Come and learn about the cold knowledge about the World Cup with Xiaobian and feel the charm of football!

Why is this year’s World Cup in winter?

In the past memory, the World Cup is always associated with summer, full of sweat, passion, beer and cheers. This time, however, FIFA World Cup Qatar 2022 was held in winter, which was mainly due to the Qatari climate.

Qatar is located in the desert area of the Middle East, with a tropical desert climate. In summer, the temperature is generally 25-46 degrees Celsius, and the highest temperature can soar above 50 degrees Celsius. This is really too hot for a player who wants to run for 90 minutes, and there is even the danger of heatstroke.

Of course, even in winter, the highest temperature in Qatar at the end of November can exceed 30℃, but the stadiums in Qatar are basically equipped with cooling systems to ensure that football players can play at a suitable temperature.

Why do players spit water?

This scene often occurs in football matches. Players take a sip of water and then spit it out immediately like gargling. Many friends will misunderstand when watching the ball. "Why do they spit everywhere?"

In fact, this is a way for players to drink water. The professional name is "carbohydrate gargle", which can effectively improve sports performance and relieve sports fatigue. It is a "scientific plug-in" for athletes on the field. They need to cheat their brains in this way without affecting their state, in order to quickly restore their physical functions and continue to play.

Why is there no British team in the World Cup?

There is no British team in the World Cup because there is no only football association in Britain.

In 1863, Britain, as the birthplace of modern football, established the world’s first football association: the English Football Association. In 1886, the football associations of England, Scotland, Wales and Northern Ireland jointly established the World Football Council and made unified rules. Later, FIFA generally joined football associations everywhere, so four football teams in Britain were invited to participate in the World Cup, namely, England, Scotland, Wales and Northern Ireland.

What is offside?

FIFA World Cup Qatar 2022 is in full swing, attracting countless fans to watch. In the first half of Argentina’s game against Saudi Arabia, it was blown offside six times, which made people confused. Many new fans will ask a question, what is offside?

Offside refers to the moment when the attacker passes the ball, the receiver stands closer to the goal than the penultimate defender, and at the same time closer to the opponent’s goal than the ball, and tries to prepare for the attack from this position. In other words, offside is an act that has a clear purpose, produces intentions quickly and puts them into practice. On the court, it is often seen that players are sentenced to offside because they start too fast and fall into the offside trap of their opponents.

The offside rule was formulated by the British Football Association in 1870. In the football match at that time, the audience often saw such a scene: when one side launched an attack, most of the attacking players had gathered in front of the other side, ready to start shooting when they received the ball, so the game between the two teams was mainly concentrated in front of the goal, and there was little wonderful cooperation. The offside rule is precisely to adjust this excessively unbalanced offensive and defensive relationship and make the game more exciting.

Cloud giant Salesforce is introducing ChatGPT function.

KlipC reports: With the global explosion of ChatGPT, American cloud service giant Salesforce has also set foot on the last bus of this storm. It is reported that Salesforce, the world’s largest CRM software service provider, launched a $250 million (about 1.74 billion yuan) venture capital investment fund on Tuesday local time, aiming at generative artificial intelligence start-ups.

According to Salesforce, the company will integrate artificial intelligence technology into the new version of software products to help enterprise personnel complete their jobs efficiently. The target customers are startups that are developing technologies similar to ChatGPT, which can be used with their commercial software applications.

According to informed sources, Salesforce began to cooperate with OpenAI’s language model team more than a year ago, but the recent popularity of this technology in the industry has prompted the company to advance its timetable and let customers enjoy some black technology as soon as possible.

Andi Duan, a partner of KlipC, said: "Since the advent of ChatGPT, there has been a storm in the technology industry. Many top technology companies have used people’s interest in generative artificial intelligence technology to launch new products. This trace once again shows that AI assistants will become ubiquitous in daily life."

However, the text generated by OpenAI’s generative artificial intelligence technology may contain wrong information. For solving such problems, Salesforce has taken several measures to avoid misleading users. For example, users still need to edit and modify answers, and Salesforce also limits the range of inventory information used to generate answers.

Wall Street analysts said in an interview with KlipC: "ChatGPT’s AI competition has recently been launched all over the world, including many top technology companies such as Microsoft, Google and Meta. With the upsurge of people’s interest in generative AI technology, the issue of moral safety has also caused controversy, and the current chat bots and language models are not mature, which has also made many related manufacturers and enterprises adopt a more cautious attitude."

Reporter: Newcastle and West Ham are potential suitors of Maguire, and they may rent first and then buy.

Live broadcast on March 11th In an interview with British media TEAMtalk, reporter Graeme Bailey revealed that Newcastle and West Ham are potential suitors of Maguire, and they may rent and buy the central defender first.

Since Tenghahe took office, Maguire has lost the main position of Manchester United. The central defender is still an important member of the English team. Therefore, in order to ensure his position in the Three Lions, it is helpful for him and the club to leave Manchester United in the summer.

Reporter Graeme Bailey revealed that Maguire is indeed a player that Manchester United can sell, Newcastle and West Ham are potential suitors of the central defender, and the two teams may sign Maguire by loan-enhanced buyout or choose buyout. This has something to do with Maguire’s salary, which is about 200,000 pounds a week at Manchester United.

Although renting Maguire out can eliminate part of Manchester United’s salary account, it will also lead to the Red Devils not receiving his transfer fee this summer, which will hardly help Tenghahe who wants to introduce center.

AIGC exploded, and the demand for AI servers in Ningchang was soaring.

With the countdown to the release of Baidu Wenxin, AIGC is bound to detonate the technology circle again. Li Yanhong, founder and chairman of Baidu, said in an internal letter after the release of the financial report: "AI technology has developed to a critical point, and all walks of life are inevitably changed. The China AI market is about to usher in explosive demand growth."

If 2022 is the first year of AIGC, then 2023 will usher in the outbreak of AIGC, and the enthusiasm for AI applications such as ChatGPT of OpenAI, Wen Xinyi of Baidu, and Yuyan of Netease Fuxi’s Chinese pre-training model will inevitably lead to a new round of fanatical demand for AI computing power.

Zhao Lei, vice president and CTO of domestic server manufacturer Ning Chang, pointed out that as far as ChatGPT is concerned, TB-level computing training library or even P-Flops computing power is needed. "There is no such thing as ChatGPT, and artificial intelligence computing power is never enough." Zhao Lei admits that the AI industry will need at least 100 times more computing power in the next 5 to 10 years.

At present, under the trend of digital transformation, enterprises’ demand for computing power is increasing, and there are many uncertainties in the development of the industry. What enterprises need more is computing power that can face increasingly complex application scenarios and balance the current business needs and future development needs.

As an AI computing expert, Ningchang provides computing solutions for users through its own technical capabilities and product solutions. Ningchang product series has covered all products such as artificial intelligence server, general server, edge server and multi-node server, meeting the needs of different scenarios and realizing flexible customized configuration. In addition, based on the existing industry energy-saving pain points, Ningchang provides traditional air cooling, cold plate liquid cooling and immersion liquid cooling and other multi-scenario cooling methods.
