Altitude Experiment: Journalist Runs 5km in Mexico City to Test

A journalist has conducted a crude experiment in Mexico City to assess the impact of high altitude on athletic performance, running 5 kilometers to simulate the conditions England's national football team will face. The results, described as significant, highlight the physiological challenges of competing at elevation.

The Experiment

Miguel Delaney, a reporter covering Thomas Tuchel's England squad, undertook the run in Mexico City, which sits at approximately 2,250 meters (7,382 feet) above sea level. He reported feeling a marked difficulty in breathing, stating, "You feel you can’t get oxygen to the bottom of your lungs." The run was intended as a rough gauge of the altitude's effect on performance.

Implications for England

England is preparing to face Mexico in a friendly match in Mexico City. The altitude is expected to be a significant factor, as players unaccustomed to such conditions often experience reduced stamina and oxygen intake. Delaney's experiment underscores the potential challenges Tuchel's side may encounter.

Background on Altitude and Sports

High-altitude environments have long been known to affect athletic performance. The lower oxygen pressure can lead to decreased aerobic capacity, with effects varying among individuals. Teams often employ acclimatization strategies, such as arriving early or using altitude training masks, to mitigate these effects. The England squad's preparation will likely include similar measures.

The video of the experiment, shared on YouTube, provides a firsthand account of the physical strain. Delaney's run serves as a practical demonstration of the conditions awaiting the team.
