England’s preparations for their FIFA World Cup Round of 16 meeting with Mexico have taken an unusual medical turn, with reports suggesting players have been given the option of using Viagra to help combat the effects of playing at high altitude. The knockout fixture will be held at the iconic Estadio Azteca in Mexico City, which stands around 7,350 feet (2,240 metres) above sea level. At that elevation, the thinner air contains less oxygen, making it harder for players to sustain high-intensity efforts, recover between sprints and maintain peak physical performance. According to reports, England’s medical team has explored several methods to help players adapt to the demanding conditions, with Viagra emerging as one of the approved options. Although the medication is best known for treating erectile dysfunction, it also works by widening blood vessels, which can improve blood circulation. Medical experts have long studied whether that effect can help athletes cope with reduced oxygen levels encountered at high-altitude venues. The drug is not prohibited by the World Anti-Doping Agency (WADA), meaning athletes are permitted to use it both during competition and outside it. WADA has examined Viagra’s potential impact on sporting performance over the years because of its influence on blood flow. However, studies have not produced conclusive evidence that it offers a significant performance-enhancing benefit at or near sea level. Its possible advantage is believed to lie specifically in high-altitude environments, where improved circulation may help reduce some of the physiological challenges caused by lower oxygen availability. For England, any use of the medication would therefore be aimed at helping players adapt to Mexico City’s conditions rather than gaining an unfair sporting advantage. The challenge awaiting the Three Lions is considerable. Mexico have built a formidable reputation at Estadio Azteca, losing only two of their 89 matches at the famous venue. Their last defeat there came in 2013, and they have carried that dominance into this World Cup by winning all four of their matches so far. England, by contrast, have had to battle through difficult moments during the tournament. Their Round of 32 encounter against DR Congo required a dramatic comeback, with captain Harry Kane scoring twice late on to seal a 2-1 victory and book a place in the last 16. Mexico secured their knockout berth with a convincing 2-0 win over Ecuador, setting up a fascinating Round of 16 contest in one of world football’s most demanding venues, where England’s preparations have included every possible measure to cope with the unique challenges posed by altitude.
