What is var? Learn about VAR Technology in football (Part 3)

VAR is most used in the area of ​​the penalty area. The decision to blow a penalty may be maintained or canceled by the referee after reviewing the video of the situation provided by VAR.

Using Var in direct red card situation

Violent acts will be prevented by VAR. However, VAR is only applied for direct red card situations, not the second yellow card.

Using Var to identify mistakes

In fact, there are many situations on the field that the referee also makes mistakes. Specifically, in the match between Arsenal and Chelsea in 2014. Oxlade Chamberlain of Arsenal was the one who made the mistake but the referee suddenly chased Kieran Gibs, another player who also owns the same head as Chamberlain. Using VAR technology, the mistakes of the referees can be corrected. However, VAR also has certain restrictions to ensure not to interrupt the game.

Application of Var technology in situations: 11m free kick, identify errors, goals and red cards directly.

Is VAR restricted to use?

Not at all, but VAR will not be used in case the game has been continued. If VAR does not detect errors, a free kick, a throw-in is automatically continued.

Goals are not determined by the VAR in the event the offensive team commits a foul in the situation leading to the goal. In general, using VAR, the referee can cool the player even though the foul situation has happened before.

Why is FIFA using VAR at Worldcup 2018?

The world’s most powerful football authority wants to improve the accuracy of decisions on the field. “I will tell football fans that this technology has a positive impact,” FIFA Infantino President said. According to the head of FIFA, VAR has been used in about 1,000 matches with an accuracy of 93-99%.

FIFA scrutinizes all the potential that this technology can bring. Infantino also said that VAR needs to improve the pace of the game analysis and communicate to the referees.

The arbitrator may consult the VAR referee team through a headset without having to review the screen.

Where to use Var?

The referee will signal using the Var technology by drawing a rectangle. The central control room will recreate two video streams and stream them to the game field, where the match is taking place with the following content.

The first video will cover every angle reviewed and analyzed by a team.

The second video from the central control room shows the team’s work here to ensure transparency.

Based on two videos provided by the central control room, the referee refuses to review them with a screen placed close to the football field, from which the referee will make the most accurate decisions in sensitive and easy situations. causing controversy in all matches that took place during the 2018 World Cup.

The central control room will always monitor each situation and developments on the pitch, not just when asked by the referees to support a given situation. The central control room will even contact the referee when a clear situation or serious error occurs.

Var technology in football has also been tested in the UK and some matches in Germany and Italy before being officially applied at Worldcup 2018. This is also the first time VAR is used in a Worldcup. Previously, FiFa also applied the goal line technology for the first time at Worldcup 2014.

In football, when is VAR used?

In a football match VAR is only used in certain situations that are: penalty kick 11m, identify errors, goals and red cards directly. Details are as follows.

Use Var to determine goals

When a team claims a goal, the referee will ask to use VAR to detect offside, pull shirts and other errors during the scoring process. And goals will not be accepted when the culprit offside offside a few centimeters.

On the pitch, there were a lot of unclear ball situations: situations that the spectator or player saw but the referee didn’t see or the situations the referee saw but the player and the audience were confused. It’s a mistake or just an accident, causing a controversial situation. To overcome this, VAR technology was born to ensure transparency in competition.

So what is VAR? How to apply Var technology in football? Invite readers to find out the most complete way about Var technology in the article below of Kienthucbongda.com


VAR stands for Video Assistant Referee, a technology that helps referees in football to help the referee make the most accurate decisions.

What does football VAR technology include?

VAR technology includes a system with multiple cameras from different angles to monitor each movement around the ball.

In addition, support for VAR technology also has a central control room (located at IBC International Broadcasting Center located in Moscow), which has a professional team to help analyze each frame and every action. of the player.

VAR information system

In the video observation room, in addition to the referee and the assistants will have a FIFA expert join. This expert is given maximum access to information exchanged between the arbitration and the VAR team, from which this person will be tasked with coordinating technology application situations through a dedicated tablet device. . The system also transmits information to TV tuners who are on live broadcast so that sports commentators can get instant updates from the match.

With the ability to access all cameras placed throughout the yard. The VAR system will give notice to the umpire in case an error is found. The referee on the field receives a signal from the video referee through a headset. He will then signal a pause in the match and let the players know that a decision is being considered. If the referee determines that a situation is free of errors, the referee will allow the match to resume.










How are sports and technology good to work together?

Sports including a lot of subjects like football, including golfing, started to be caught up in the development and “invasion” of technology. It can be seen that in every aspect of life, technology can penetrate, not just sports.

But what is the beauty of sport? It is the admiration for the ability to handle, technical players. Strong opposition or strong agreement with the arbitration’s judgment or tingling stories about a situation where a shooting angle on television cannot express clearly.

For example, golf is also applied virtual golf room or equipment mounted on the sticks to analyze the shot of the player has created many objections. Those who disagree that technology will destroy the inherent nature of sport.

For more comments on this issue, I contacted a long-time golfer, to ask him if technology would change the nature of sport.

He shared with the general idea as follows: Technology or technology equipment, obviously they are very useful for sports players. If football has equipment for analyzing player scores, so does golf. Smart cameras, intelligent measuring devices have been developed and have been added to golf.

But they only stop at analyzing the swing or other factors during training. While playing, according to the expert, all must be removed from the game so that the true nature of golf is not affected.

“Using technology to serve during training is good, but used during competition, I do not support and do not want to bring them into golf”.


Thus, we can see, technology and sports and life can work together. But should only stop at a certain level. What happens when playing football, the decisions made by the machine to 100% accurate and we have no emotional moments in an argument?

Or like golf, thanks to the technology, the story goes exactly 1 stick and the ball will enter the hole will be easy because the equipment has analyzed it all to get this. Thereby the sport becomes more calculated and also loses the surprise and joy because in the past, not everyone had the opportunity to do this.








MU starts using the facial recognition technology instead of tickets

Man City experimented with facial recognition technology instead of tickets to the Etihad stadium.

Man City is experimenting with face recognition technology to replace tickets for the field to watch Pep Guardiola’s team play at Etihad. In a pilot plan, Etihad will set up a super-fast entrance to the pitch for NHM. This project will be implemented by Blink Identity, based in Texas, USA.

According to the design team in charge of the project, the technology they applied can scan 50 faces within a minute, can identify whether fans are allowed to enter the yard and the notification signal is displayed by the indicator light system.

The system of Blink Identity will not have the familiar turnstile but will display green if the access is valid, and a yellow display means that the fans cannot enter the field.

To be able to enter the pitch through Man City’s facial recognition system, fans need to access an app via phone, take a selfie and register. Man City’s use of this technology is to prevent ticket sales and transfers all season long.

Man City experimented with facial recognition technology instead of tickets to the Etihad stadium. Face recognition technology will be applied by Man City instead of traditional tickets

This is not the first time Man City has applied new technology. Last season, Pep Guardiola introduced Artificial Intelligence (Al) technology during training with the SAP Challenger Insights application, which allowed him to keep track of the players’ data.

Etihad Stadium has also used 360-degree rotating cameras, Intel’s 3D True View technology can bring a better experience for NHM to watch through television. Outside the Etihad Stadium, Man City also built “CityPulse Wall,” a large interactive screen that gives NHM the opportunity to analyze data and data.

Man City is also the first English Premier League team to broadcast the match using Virtual Reality (VR) technology.

Also, there are other steps you need to take to make sure everything is being tracked.

Certainly, there are lots of useful information you can get from wearing smart shirts, in which heat maps are a favorite part of many players. What to consider when wearing a shirt is the time you start and stop (to be as accurate as possible) plus that you need the internet to notify the system exactly where you are playing on the field.

However, in addition to the positive points like shirts that wrap around the chest, monitor important performance data, allowing comparison of personal data with professional players, providing feedback to help you can improve, the drawback of smart shirt is that the wearer only feels more comfortable with a T-shirt underneath, needs a phone to upload the application, the shirt does not work because SmartPod has problems.







Technological and scientific trends applied in modern sports

Athletes are the most healthy people in the world. However, they also pushed their bodies to the limit on a regular basis. Whether athletes are trying to be faster or stronger, or they just keep playing and exercising despite fatigue, they are muscular, joints and the whole body is overworked.

Outstanding sports science trends over the past few years include the use of analytics to prevent injuries, the use of new injury recovery systems, analyzing sweat and wearable technology.

Analysis to prevent injury

The risks of injury during exercise or sports are common. Many athletes suffered serious injuries that caused them to take a break for three months or longer. In fact, it is rare to see a professional athlete who does not have at least one or two serious injuries in his career.

An example of such technology has VU of Pivot. VU is a device that uses Pivot sensors to understand the body and performance in real-time. This technology is capable of analyzing athletes ‘grounding, cutting, sprinting and other movements to understand athletes’ performances and techniques.

VU can also be used to help athletes recover muscle or bone injuries when their movements are monitored and analyzed during each recovery step. By using such technology, teams and individuals can understand whether specific techniques cause injury or if they are only suffering from excessive fatigue or stress.

Injuries not only rob the athletes of time but also cost the team. Estimated player injury costs in four major European football leagues – Premier League, Bundesliga, La Liga and Serie A – amounted to $ 100 million in 2015.

Therefore, sports teams and athletes want to use technology and data to help understand why athletes suffer from specific injuries and prevention.

Injury recovery system

Cryotherapy is an extremely popular method in sports and it is gaining a lot of attention in the past few years. The concept of cryotherapy is to expose parts of the body to freezing or near freezing temperatures. Although it is not the most interesting experience, especially for those who hate colds, it is said to help recover in the sports season.

Recovery from injury is not only about the body, but also the mind. Athletes with severe injuries, such as complete muscle tearing or fractures, may face mental obstacles when they prepare to return to training. Many teams begin to understand the mental and psychological impact of injury on athletes.
