What if there are players in the World Cup who need to urinate during a match?

Players consume a lot of water when running, so they usually don't feel the urge to pee.

Can't help it, players can apply for a special timeout.

Faint spoof you.

How many times do you go to the toilet in class, can't you adjust it reasonably?

Players should live a reasonable life to maintain good physical condition.

If it happens, the football player is not a qualified person.

It's better not to.

It's a sharp question.。。 Actually, this is not a problem at all.

Before going on the field, you must control the amount of water you drink, and this kind of problem generally can't happen.

More obviously, people who exercise are aware. That's running, a lot of exercise, not enough sweat, where does the urine come from? In fact, there is a halftime break in football, which is one hour at most. When you're basketball, you're going to be sharp if you run the locker room for that reason.

Yes, LZ's perspective on the problem is indeed very powerful

I'm afraid 45 minutes is fine, unless the kidneys are weak, hehe.

Hold it back, and you can urinate directly when it rains heavily.

Sweating more, urinating less.

Uh, it's so boring, you can wait until halftime.

When you sweat all over your body after strenuous exercise, the water is dissipated, where do you get the excess water to urinate, even if there is, endure it for a while and be absorbed by the body for a second time because of thirst

Solve personal problems before you go on the field.

The referee will be the referee, don't worry, generally this kind of thing rarely happens, but there is always a possibility!

The general fourth** is the referee's substitute, and the other substitutes are the assistant referee's substitutes.

The fourth referee is dedicated to this situation, and the referee blows the whistle for the fourth time when the referee leaves the field. Every cup tournament will prepare a fourth referee to deal with emergencies.

There are substitute referees, and the only referee selected in China this year was the substitute referee in the opening ceremony.

Blown by the fourth**, when Tottenham Hotspur played with Portsmouth last year, the referee suffered a muscle strain, and the fourth** blew the ball I watched.

The referee is the referee.

Generally, the main strikers are around 20,000 meters, and Messi only ran about 13,000 meters in the Champions League this year, and he was scolded for not running actively. 20,000 meters in the World Cup is normal.

It's generally about 12 kilometers, and it's also divided into people, the central defender has a large range of activities, and he should run more, and the goalkeeper is needless to say, there should be a quarter of the central defender!

A player's physical exertion is related to the distance they run on the field. Two researchers at Liverpool's John Moores University have measured that midfielders are the most tired in football, running an average of 13 kilometres per game; Forwards and defenders are second, running kilometers and kilometers respectively; The centre-back has to run kilometers. The goalkeeper is the most "relaxed", with a distance of only one kilometer.

Most of it is in English, because more or less in the club, of course, North Korea... Gestures are everything.

Generally speaking, players and referees cannot communicate in detail on foreign courts, but general teams require players to know general football rules in English, as well as gestures, and referees are more strict than players, so if you see a bunch of players surrounding the referee, the players generally repeat a few simple words or scold in their own language.

There will be some professional gestures to accompany the instructions.

Gestures, colored signs!

A total of 7 group stage matches, three round of 16, round of 8, round of 4 championship round.

It depends on whether it is a single cycle or a multiple cycle.

Measuring this data is not as complicated as it seems, and the main way to measure it is to use a video camera and a high-tech software product. ”

Eight cameras are placed in various corners of the pitch, all of which have thermal imaging capabilities, which are able to record the situation on the pitch and the performance of all the players throughout the game. All the information captured by the camera is broken down by a set of ultra-sophisticated analysis software that can count the distance a player has traveled during a match at any given time.

For example, if the operator locks on the No. 7 individually, the software will be able to find the No. 7 player in the video and make a series of analyses of his performance on the field, and the distance he has traveled will be immediately determined. ”

"The France-based data company SUP (Sport Universal Process) is a leader in measuring the data of players in matches. The company has been hired for analysis for a number of European clubs. In the data sampling competition, 8 advanced cameras with thermal imaging functions are installed in the stadium and used to record the whole process of the game.

The information captured by the camera is broken down by a set of ultra-sophisticated analysis software, and the end result is what the customer sees, and the data is categorized in such detail.

Here are the features and benefits:

Functions: 1. Present the 2-dimensional running of the team players;

2. Synchronize with the game video;

3. Integrated graphical tools: offside, module, line;

4. Complete individual and team statistics;

5. Charts, **, data in the form of lists;

6. Measure physical activity and physical fitness report;

7. Personalization rules;

8. Data can be output to third-party applications;

Advantages: 1. Full view of the game (you can see the whole game);

2. Observe the game with or without the ball;

3. Measure efficiency individually or as a whole;

4. Confirm the tactical system;

5. Innovation in support of individual players;

6. Support for physical training programs.

Deciphering the running distance method: 8 advanced cameras with thermal imaging functions are installed in the stadium to record the whole process of the race, and the captured information is broken down by a set of ultra-sophisticated analysis software, and the end result is that the extremely detailed data is counted in different categories. According to FIFA statistics, the cumulative distance traveled by professional football players on the whole field is 1w meters on average.

The average running distance of players in the Chinese Super League is only about 7km.

In fact, this is a professional problem, in fact, it is counted with an infrared tracking system, the system will scan everyone on the field, automatic statistics, it seems simple, the equipment is placed above the stadium with an instrument, and it is OK.

It's easy to take advantage of modern high technology.

Specifically, it seems that a small chip is added to the shoe (very small, which will not affect the normal game), and it is easy to draw conclusions using the statistics of TV media.

The number of starters is: 11.

Number of team members:

1；A match shall be played by two teams with no more than 11 players per team, one of whom must be a goalkeeper. If any team has less than 7 players, the match cannot start.

2；In official matches hosted by FIFA, continental federations or national associations, a maximum of 3 substitutes can be used per match.

3；The rules of the competition shall state that several substitutes may be nominated, ranging from 3 to a maximum of 7.

The starters, that is, the ones who could play at the beginning, were 11 and there were seven on the bench. Call the list of 18 people, 23 people are the number of people who can be brought, in a single game, as long as the 18 people who have signed up are eligible to play this game.

There have been a few players that I know of who died on the spot or after being sent to the hospital because of the pressure, the intensity of the game, and the intensity!

No, ... There are several who died of overwork. But not at the World Cup either.

High-level, very accurate.

Not unless you deliberately kill the other person. Task.

I heard that there was a man who had a donkey kicked in the head, and I don't know if he died or not. Do the task.
