As the United States continues in the World Cup, the team will strive to capitalize on the home-field advantage that comes with serving as the host country.
While fans often think of home-field advantage as simply having a supportive crowd, a Virginia Tech researcher says the phenomenon is much more complex.
“I think people appreciate that being at home can offer many advantages but might not be aware of the multitude of reasons why,” said , assistant professor of industrial-organizational psychology at Virginia Tech, who has done research related to sports analysis and methodology.
The U.S. opened the World Cup with a convincing victory over Paraguay in California and remains on the West Coast for its next match, avoiding the cross-country travel challenges many teams face. Hernandez said advantages such as familiarity, rest, crowd support, officiating dynamics, and even environmental conditions can all influence performance.
Hernandez said sports with denser attendance and greater crowd intensity tend to produce larger advantages for home teams. Soccer has some of the highest home winning percentages across professional leagues worldwide. Across 10 sports examined, soccer has the largest average home advantage across leagues, with a high of 69.1 percent in Major League Soccer, the highest professional soccer league in the United States.
Hernandez groups home-field advantages into three broad categories:
Motivational advantages include the psychological boost players receive from supportive crowds.
Physiological advantages include factors such as reduced travel, better rest, and familiar surroundings.
Structural advantages can come from stadium conditions, crowd influence, and even subtle effects on officiating.
Altitude can have a major impact. Hernandez points to Mexico City’s elevation and summer conditions as examples of how environmental factors can create challenges for visiting teams through fatigue and dehydration.
Research also suggests that home-field advantage is not always about the players. Evidence across major team sports indicates that crowds can influence officiating, with referees sometimes making close calls that favor home teams.
