Ahead of their June 22nd match, the Argentinian national football team has been observed training with refrigerated vests and insulated boots. Sports physician Jorge Franchela explained the reasoning behind this equipment to LN+, citing concerns about the heat. The devices are designed to help players regulate their body temperature during intense training sessions and prepare for potentially challenging weather conditions during the 2026 World Cup. Franchela indicated the team is proactively addressing the impact of heat on performance. This strategy aims to mitigate risks associated with heat exhaustion and maintain optimal player condition. The use of this technology highlights the increasing importance of physiological preparation in modern professional football.
