England are preparing to face Mexico at the Azteca Stadium, situated 7,220 feet above sea level, in a World Cup round-of-16 match. The high altitude means players will breathe more heavily and fatigue more quickly, posing a significant challenge for Thomas Tuchel's side.
What Is Altitude and How Does It Affect Players?
At higher elevations, atmospheric pressure is lower, so the air contains less oxygen. With each breath, players take in less oxygen, leading to faster fatigue and longer recovery times between intense bursts. Cooler, drier air also increases dehydration risk during exercise.
Tuchel admitted his team will be at a 'huge' disadvantage, as ideal acclimatization requires weeks, but England only arrived in Mexico City 48 hours before kick-off.
Strategies to Aid Performance
Former athlete Steve Magness outlined several methods to help players cope. The first four are straightforward: maintain hydration, fuel with carbohydrates, use sodium bicarbonate ('bicarb') loading to buffer acid build-up, and protect sleep. Bicarb-rich foods include spinach, kale, carrots, and beans.
Tactics and pacing are key—reserving energy and timing runs can prevent early fatigue. A well-timed dose of caffeine, ideally at half-time, can also boost second-half performance.
Beetroot Juice and Pickle Juice
Beetroot juice, packed with nitrates that boost nitric oxide, widens blood vessels to improve blood flow and muscle efficiency. Pickle juice, the 'magic potion' from Euro 2024, is rich in electrolytes to support muscle function and hydration, reducing cramp risk.
Sleep and Recovery Aids
The FA have researched altitude effects and consulted other sports teams. They decided against oxygen therapy but are using high-tech palm-cooling devices to combat heat. Players and staff are offered natural sleep remedies or white noise audio machines to ensure quality rest, according to the BBC.
England have been in the US for weeks, so they are accustomed to heat, which affects the body differently than altitude. While full adaptation is unlikely, these measures aim to minimize the impact.
