100meter

100meter is a sprint event in track and field run outdoors on a standard 400-meter oval. The race covers a straight 100 meters from the starting blocks to the finish line, with athletes exploding from rest, accelerating through the early phase, and attempting to sustain top speed through the final meters. Times are recorded with automatic timing systems, and wind speed is measured; for record eligibility, wind assistance must not exceed 2.0 meters per second.

The 100meter is one of the premier events in athletics, featured at major competitions such as the Olympic Games and the World Athletics Championships. It is known for extreme speed, precise starting technique, and highly analyzed phases of acceleration, maximum velocity, and late control. The current men’s world record is 9.58 seconds, set by Usain Bolt in 2009 at the World Championships in Berlin. The women’s world record stands at 10.49 seconds, set by Florence Griffith Joyner in 1988 at the Seoul Olympics.

Race dynamics depend on several factors, including reaction time to the starting signal, starting block technique, sprint mechanics, and the ability to maintain form while fatigue and crowding influence performance in the final meters. False starts—caused by reacting to the start signal too quickly—lead to disqualification under standard rules. Modern competitions rely on electronic timing, photo finish technology, and wind measurement to ensure fair comparisons and record recognition.
