The term "false start" in athletics refers to when an athlete begins their race before the starting gun has been fired. This infraction can lead to disqualification in some events, especially in sprinting competitions. False starts disrupt the fairness of the race, as they provide an undue advantage to the athlete who jumps the gun. To maintain a level playing field, strict regulations are enforced; competitors are often given only one chance before facing penalties, emphasizing the importance of focus and discipline in track and field events.
