Scientists have measured that an average human takes one-tenth of a second to react to a stimulus, such as the starting gun. In the Olympics, the clock stops if an athlete begins sooner than a tenth of a second after the signal is given, as a result of this means she or he began to “react” earlier than the gun was fired. For the lengthy-distance skiing occasions, such as cross-nation and Nordic, RFID tags connected to every skier’s boot send particular person alerts to antennas buried beneath the snow at the beginning line, end line and factors in between. In this way, a skier’s beginning time, finishing time and progress are all tracked, recorded and broadcast, taking any time penalties into consideration. GPS satellites are also used for the Nordic competitions to measure distances between opponents throughout the race. The course of works the same for the person events such as breaststroke, freestyle and backstroke, during which the swimmer registers his or her time by urgent on the contact plate on the finish of the run.
