The Qatar World Cup has crossed the 100-day countdown, and as the first World Cup to be held in the northern hemisphere in the winter, this international football feast has received more and more attention, when it will present more "new meanings" to fans.
The air-conditioned course is unique
It will be an unconventional World Cup, as the World Cup is mostly held in June and July, the mid-summer World Cup that fans are accustomed to. Brazil and South Africa have both hosted the World Cup in the winter, but they are both southern hemisphere countries, and it is still in June and July. Qatar's weather is extremely hot, and it is completely impossible to host the World Cup in June and July, so this World Cup will be held from November to December, which will directly affect the European club competitions in the New Year's Day.
Although Qatar will enter winter by then, the average temperature is still very high. In order to create a comfortable playing environment for players, the air-conditioned stadium came into being, and the Qatar World Cup stadium will use cooling technology.
The design of the cooling technology on the pitch was inspired by the study of car air conditioning. The cooling of the stadium is like the cooling principle of the motor vehicle, and the technicians use similar tools and principles in the cooling technology, and the scale of the cooling is undoubtedly greater. This cooling technology combines thermal insulation with the concept of "directional cooling", which means that cooling will act on the area where the human body really appears, making the stadium like a barrier, containing a "cold bubble".
The "dumpling skin" mascot is super cute
The World Cup has come to Asia again after 20 years, the last time it was jointly organized by South Korea and Japan, and this time by the Gulf state of Qatar. After entering the 100-day countdown to the opening, Qatar's World Cup mascot La'eeb (alias "Ra'ib") will be pre-sold on the domestic sales platform.
Inspired by the traditional Arab headdress, Ra'ib is mischievous and cute, with a cute expression and a length and width of about 33 centimeters. As soon as the mascot was released, it was loved by many fans and fringe fans, because of the cute and exquisite dynamic shape, Raib was named "dumpling skin".
Ra'ib is an Arabic word that stands for skilled players. Raib means eternal youth, comes from the "mascot universe" and is at the same time full of vitality. Raieb encourages everyone to believe in themselves that the World Cup in Qatar is about to begin and will bring the joy of football to everyone.
A company in Hangzhou, China, became the official licensor of the 2022 Qatar World Cup in Greater China, and before that, the company had been continuously operating the production and sale of licensed goods for the 2014 Fifaccia World Cup in Brazil and the 2018 FIFA World Cup in Russia.
The roster is the longest in history
FIFA officially announced as early as June that the final roster for the 2022 World Cup has been expanded from the traditional 23 to a maximum of 26. In the World Cup group stage matches, each team can make up to five substitutions; Because knockout rounds may require extra time, each team can make up to six substitutions. The Expansion Plan of the World Cup should be more beneficial to the overall stronger team.
The reason for the introduction of this expansion measure is that FIFA has given the coaches of various teams more room for maneuver in order to prevent the international football team from being infected with new crown pneumonia during the World Cup. The squads for the World Cup primaries have been significantly expanded, from a maximum of 35 players to a maximum of 55 players.
In order to prepare for the World Cup, the players on the final squad of each participating team must finish their last match at the club by 13 November at the latest. During world cup matches, each team can seat up to 26 people on the bench, including up to 15 substitute players, as well as 11 team staff (including at least one team doctor).
Artificial intelligence assists referees
Modern technology is changing with each passing day, and the appropriate application of new technologies to football games to minimize misjudgment and missed judgments is the gospel for fans and football. For the first time, the Qatar World Cup will officially use semi-automatic offside penalty technology, which will use artificial intelligence to assist referees and referees to make more accurate offside penalties and minimize offside misjudgments.
The AI technology will use 12 dedicated cameras to track each player's exact position on the pitch at 29 data points, including the limbs and torso involved in determining offside.
This technology also requires the tacit cooperation of the game ball, and an inertial measurement unit sensor will be placed in each game ball. Located in the center of the ball, the sensor sends data to the VAR operating room at a frequency of 500 times per second, helping the referee to accurately detect whether a player on the field is offside.
The Journey flies the fastest with a ball
FIFA recently wrote in a statement: "The 'journey' we show you is the official match ball for the 2022 World Cup. ”
The Qatar World Cup match ball "journey" will be the fastest flying football in any World Cup, and it is also the 14th consecutive football made specifically for the World Cup by Adidas. At the Qatar World Cup, fans can expect the fastest-flying football to make goals faster and more produced, which can be a boon for free-kick experts such as Cristiano Ronaldo, Messi, Neymar, or a nightmare for goalkeepers.
In addition to the particularly fast ball speed, the "journey" of the World Cup ball has other characteristics: for example, the surface of the football is composed of 20 textured PU skins, thereby improving the movement stability of the ball; The center design of the ball provides speed, accuracy, motion consistency, and aerial stability support for fast-paced movements.
The transfer has never been easier
Paris Saint-Germain has been funded by the Qatar National Fund, and in the transfer market over the years, fans have already learned the strength of oil capital. Hosting the World Cup in Qatar, an arrogant country, will naturally cost no small amount. Qatar has a budget of about $220 billion to prepare for the 2022 World Cup, far more than the record $14 billion invested at the World Cup in Russia four years ago, making it the most expensive World Cup in history.
Of all the budgets, about $10 billion will be spent on the construction of new stadiums needed for the World Cup, while the remaining $210 billion is not entirely for the World Cup, which is a long-term investment in Qatar's 2030 plan and will be used to build an innovation center in the local area that includes hotels, underground transportation, stadiums and airports, and will continue to be used for a long time after the World Cup.
It's also special that Qatar World Cup teams don't have to travel long distances from one venue to another in order to compete in the next match, which is very different from the previous World Cups in Russia, Brazil and South Africa. All 8 World Cup stadiums in Qatar are within an hour's drive and are easily accessible.
