England’s preparations fifa world cup The Round of 16 match against Mexico took an unusual medical turn, with reports that players may have the option of taking Viagra to help combat the effects of playing at high altitude. The knockout games will be held at Mexico City’s iconic Estadio Azteca, which is approximately 7,350 feet (2,240 meters) above sea level. At this altitude, the thinner air contains less oxygen, making it more difficult for athletes to sustain high-intensity efforts, recover between sprints, and maintain peak physical performance. It is reported that England’s medical team has explored a variety of methods to help players adapt to the harsh conditions, with Viagra becoming one of the approved options. While this drug is best known for treating erectile dysfunction, it can also improve circulation by dilating blood vessels. Medical experts have long studied whether this effect could help athletes cope with the reduced oxygen levels experienced at high-altitude venues. The drug is not banned by the World Anti-Doping Agency (WADA), meaning athletes can use it during and outside competition. For years, WADA has been studying Viagra’s effects on blood flow and thus its potential impact on athletic performance. However, research has not produced conclusive evidence that it provides significant performance-enhancing benefits at or near sea level. It is believed that possible advantages lie particularly in high-altitude environments, where improved circulation may help reduce some of the physiological challenges caused by lower oxygen utilization. Therefore, for England, any use of drugs is to help players adapt to the conditions in Mexico City, rather than to gain an unfair sporting advantage. The challenges that await the Three Lions are huge. Mexico has built a formidable reputation at the Estadio Azteca, losing just two of 89 games played at the famed venue. They last lost there in 2013 and they have continued that dominance into the World Cup by winning all four of their games. England, by contrast, had to go through tough times during the World Cup. They faced the Democratic Republic of Congo in the last 32 and needed a dramatic comeback, with captain Harry Kane scoring a late brace to secure a 2-1 victory and a place in the last 16. Mexico sealed a knockout spot with a convincing 2-0 victory over Ecuador, setting up an exciting last-16 tie at one of the most demanding venues in world football, with England’s preparations including taking every possible step to deal with the unique challenges posed by the altitude.
