The altitude effect of the World Cup in Mexico, how altitude affects football matches

The 1986 Mexico World Cup was held in Mexico City and other plateau cities at an altitude of 2,240 meters. Players from Germany, France, and Spain, who are from sea-level European countries, felt difficulty breathing as soon as they got off the plane, and their physical energy consumption during the game was twice as fast as on flat ground. Maradona's Argentina relied on the advantages of South American players' relative adaptability to the plateau and his personal genius to win the championship all the way. This is the most typical plateau effect in the history of the World Cup.

The altitude effect is a long-discussed topic in the football world. The oxygen content of the air decreases by about 10% for every 1,000 meters of altitude increase, which has a huge impact on athletes' physical fitness. La Paz, Bolivia, where Mexico City is nearly 3,000 meters above sea level, has even banned competition. Understanding the plateau effect is also key to understanding the geography of football.

Scientific principles of plateau effect

The human body has thin oxygen in a high-altitude environment, and the ability of red blood cells to carry oxygen decreases. The oxygen content in the air above 2,000 meters above sea level is about 15% lower than at sea level. The oxygen content is about 30% lower at altitudes above 3,000 meters. Athletes need more breaths to get the same amount of oxygen. The heart rate increases and muscles tire prematurely. Athletes from sea-level countries who compete at high altitudes usually need an adaptation period of 2 to 3 weeks to return to normal conditions. There is no time to adapt in a short game.

The plateau of the 1970 World Cup in Mexico

The World Cup was held in Mexico for the first time in 1970. Mexico City (2240 ​​meters), Guadalajara (1566 meters) and Toluca (2680 meters) with higher altitudes are all competition venues. European teams reacted significantly. Italy's 4-3 overtime victory in the match of the century against Germany was called the Battle of the Plateau. The 120-minute long game consumes a lot of physical energy, and many players are exhausted after the game. However, Brazil finally defeated Italy 4-1 to win the championship. South American players are obviously better at adapting to the plateau than European players.

The plateau of the 1986 World Cup in Mexico

Sixteen years later, the 1986 World Cup was held again in Mexico, making Mexico the only country to host the World Cup twice. Argentina won this World Cup and Maradona led the team single-handedly. Before the Belgian semi-finals, the coach admitted that the altitude had severely depleted the players' physical strength and that they were unable to compete with Argentina for 90 minutes. Germany's physical fitness declined significantly in the 120 minutes against Argentina in the final. Part of the reason for Maradona's goal of the century, which surpassed five players in a row, was that the English players could not catch up with him on the plateau.

Plateau War in La Paz, Bolivia

La Paz, the capital of Bolivia, is one of the highest football stadiums in the world at an altitude of 3,640 meters. The Bolivian national team's winning percentage at home is therefore much higher than away. The visiting team came to La Paz and almost all lost. Argentina's 2-1 loss to Bolivia in La Paz in 1993 was one of the biggest upsets in the history of the Argentine national team. FIFA considered banning games above 2,750 meters, but Bolivia protested and ultimately retained its traditional home ground. This geographical advantage makes Bolivia a special presence in the South American qualifiers.

The plateau advantages of Quito, Ecuador

Quito, the capital of Ecuador, is located at an altitude of 2,850 meters, and the national team’s home stadium is also on a plateau. In the 2002 World Cup qualifiers, Quito, Ecuador, had a home record of 9 wins and 1 loss, sweeping almost all the strong teams. Finally entered the World Cup for the first time in history. It is difficult for the visiting team to win in Quito. This is the key to Ecuador's multiple World Cup tickets. Bogotá, Colombia, at an altitude of 2,640 meters, has a similar situation. The plateau battle in the South American qualifiers is the most interesting case of football geography.

Scientific training for plateau adaptation

Modern professional teams have specialized scientific training for plateau competitions. One is to adapt to the plateau 2 to 3 weeks before the competition. The second is to return to sea level for training before returning to the plateau. The third is to use a hypoxic tent to simulate a plateau environment. The fourth is to supplement iron to help produce red blood cells. Altitude training has become standard for Olympic marathon and long-distance runners. However, it is still difficult for the football team to fully adapt to short-term games, and it mainly relies on the players' own physical reserves.

The Counter-Plateau of the 1994 World Cup in the United States

Some of the venues of the 1994 World Cup in the United States were located in hot, low-altitude environments, which made teams accustomed to the temperate zones of Europe uncomfortable. The 30-degree high temperature at the Rose Bowl Stadium in California at noon in the United States caused the physical fitness of European players to decline. This anti-plateau effect is also a type of geographical factor. From a scientific point of view, high temperature and high altitude both increase athletes' physical consumption, but the mechanisms are different. The environmental differences among the places where the World Cup is held make each tournament have its own geographical battles.

Qatar 2022 out-of-season

The summer temperature in Qatar is 50 degrees and it is impossible to hold games. FIFA has moved the World Cup to the winter period of November and December for the first time. This is another geographical factor. The European leagues were forced to interrupt to make time. Players go from the middle of a club season straight into the World Cup without the normal offseason preparation. This kind of out-of-season competition complicates the physical condition of all strong team players. Argentina's final victory in the Middle East winter showed the ultimate realization of Messi's dream.

Controversy over geographical advantages

Whether the plateau advantage is fair or not is a long-standing controversy. Some advocates abolishing the plateau advantage and believe that football should be played under fair geographical conditions. Others advocate preserving traditions, believing that the plateau is a natural resource for these countries. FIFA ultimately chose to retain diversity, rotating World Cup match locations into different geographical environments. The environment of each World Cup venue affects some of the team's strengths and some of its weaknesses. This geographical diversity is part of the World Cup's charm.

Geographic differences in hosting the three countries in 2026

The 2026 World Cup will be co-hosted by the United States, Canada and Mexico. The competition venues include the Mexico City plateau, the temperate zone of Toronto, Canada, the humid and hot Florida of the United States, and the dry climate of California. The biggest difference in geographical environment in the same World Cup. The team needs to adapt to a variety of environments. Mexico City's Estadio Azteca will once again witness high altitude competition, the third World Cup hosted by the stadium. Understanding the plateau effect is also the key to understanding tactical preparations for the 2026 World Cup.
