Officials are like athletes in that they have to perform at their best in every event. Staying focused, making correct decisions, and managing equipment and personnel are essential. To perform these tasks consistently and reliably, officials must be refresh and well organised. This is especially so for officials who have demanding physical roles, such as football referees and hockey umpires, and for officials who need to make precise decisions about high-speed movements over a long period of time, such as judges in artistic or combat sports. Monitoring fatigue and stress levels, and learning how to minimise their effects are things that both athletes and officials have in common. This helps officials to be reliable and consistent in their roles.
