SALT LAKE CITY — Korea’s national football team is turning to advanced sports science as it prepares for what could be one of its toughest challenges at the 2026 FIFA World Cup: adapting to the high-altitude conditions of Mexico.

Led by manager Hong Myung-bo, the Taeguk Warriors will play their first two group stage matches next month in Guadalajara, Mexico, which sits at an elevation of 1,571 meters (5,157 feet) above sea level.
