How European teams are trying to beat the World Cup heat
How European teams are trying to beat the World Cup heat focuses on the physical impact of tournament conditions and the testing meant to prepare players. Using a specially built lab on the south coast of England, Precision Fuel and Hydration recreates heat environments expected at World Cup venues in North America. During a simulated 50-minute session—30 minutes running plus 20 minutes uphill—exercise led to a 0.64% body-weight drop and a 1.55°C rise in core temperature, with estimated performance capacity falling by about 10% in under an hour. The article uses Wet Bulb Globe Temperature (WBGT) as a benchmark, citing FIFA recommendations that games be postponed at 28°C WBGT, while modeling suggests around a quarter of matches could exceed 26°C. It also notes an expert May warning letter and explains how heat reduces high-intensity running and repeated sprints.
