Performance Impact

ALTITUDE (EXTREME): At 2200m, oxygen density is reduced by approximately 20%. Research shows VO₂max decreases ~7-8% per 1,000m of altitude (Esh et al. 2026, Sports Medicine). This means unacclimatized players will experience:

• ◆~17% reduction in aerobic capacity
• ◆Faster onset of fatigue, especially in the second half
• ◆Reduced sprint recovery between high-intensity efforts
• ◆Altered ball flight: shots travel faster and curve differently in thinner air
• ◆Equivalent to approximately 1.1 goals advantage for altitude-adapted teams

Teams adapted: Mexico (home), Ecuador (trains at 2,850m in Quito), Colombia (Bogotá at 2,640m), Iran (Tehran at 1,200m) Teams most vulnerable: All European sea-level nations, Japan, South Korea, Australia, most African teams

Stadium Characteristics

• ◆Type: Open-air
• ◆Air Conditioning: No
• ◆Roof: No
• ◆Key concern: EXTREME ALTITUDE (2200m): VO₂max reduced ~17% for unacclimatized teams. Ball travels faster in thinner air. ~1.1 goal equivalent advantage for adapted teams.
