An unusual practice took place in a recent qualifying match for the 2026 World Cup between the national teams of Bolivia and Uruguay (0:0), held in El Alto.
The "Estadio Municipal de El Alto," where this match took place, is located at an altitude of 4.1 km, the air there is significantly thin and people who are not adapted to such weather conditions find it difficult to breathe. Especially under physical loads.
For this reason, the Uruguayan football players used portable oxygen masks.
