Color of soccer goalkeepers’ uniforms influences the outcome of penalty kicks

This study examined the proposition that competing against red-clad opponents hinders the performance of soccer (football) athletes. 40 experienced players took 10 penalty kicks against a goalkeeper wearing a black jersey and, 1 week later, took 10 penalty kicks against a goalkeeper wearing either a red, green, blue, or yellow jersey. Prior to each set of kicks, participants reported their expectancy of success. Players facing red-clad goalkeepers scored on fewer penalty kicks than those facing either blue- or green-clad goalkeepers, but no differences in expectancy of success emerged. The findings indicate that athletes wearing red may have an advantage over their opponents.
