Costa Rican soccer coach Jorge Luis Pinto said he doesn’t want girlfriends and wives flying around Brazil to be with the team during the World Cup, and noted that players will need to stay isolated and focused. Added Pinto: “I can assure, with no doubts, they will be able to ‘enjoy themselves’ just as soon as they qualify for the next round.”
Although it’s often said that sex can be a distraction and exhaust players, no scientific studies support either claim. Still, teams like Mexico, Chile, Spain and Bosnia and Herzegovina have banned players from having sex during the tournament, according to this handy guide from Deadspin. Mexico coach Miguel Herrera justified the decision with this simple explanation: “Forty days of sexual abstinence is not going to hurt anyone.”
Italy reversed previous policies banning sex at the World Cup, while the French have said sex is fine as long as it’s not the only thing the team does to prepare for matches. The United States coaching staff said they have more
important issues to worry about than whether their players are "knocking cleats" with their chicas.
