No, England did not use hypoxic training for the 2026 World Cup. Instead, the team relied on specialists from Team GB and global experts to help players adapt to the tournament's high humidity and heat.

Key preparation methods included:

Thermal Monitoring: Players took capsules during a warm-weather training camp in Florida to measure internal body temperature and cooling rates.
Acclimatization: The squad spent time in the humidity of Florida and played warm-up matches in hot conditions to get used to the environment.
Hydration Strategy: The team treated hydration breaks, introduced due to the heat, as a practice opportunity to manage fluid intake.
Head coach Thomas Tuchel explicitly stated that they had planned for the conditions using these adaptive solutions rather than hypoxic methods.
