100 m (one hundred metres) is the shortest outdoor sprint race distance in athletics. The reigning 100m Olympic champion is often named "the fastest man/woman in the world".

On an outdoor 400m running track, the 100m is run on the home straight, the start being set on an extension to make it a straight-line race. Illegal drug use has been seen by some people as a means to gain a competitive edge; in particular, the scandal at the 1988 Summer Olympics when the winner, Ben Johnson, was stripped of his medal.

Record performances

Major 100m races, such as at the Olympic Games, attract much attention, particularly when the world record is thought to be within reach.

The men's world record has been improved upon eleven times since the introduction of electronic timing in 1968, never being surpassed by more than 0.05s at a time. The current men's world record of 9.58s is held by Usain Bolt of Jamaica, set in Berlin on August 16, 2009. The current women's world record of 10.49s belongs to Florence Griffith-Joyner, set in Indianapolis, Indiana, on July 16, 1988.

Due to the progression of record times compared to longer distances, the downward march of the 100m record has been criticized as more a measure of technological advances than athletic greatness.[1]

Start

At the start, some athletes play psychological games such as trying to be last to the starting blocks, although direct intimidation would be considered unsporting. The starter will keep the sprinters in the set position for an unpredictable time of around two seconds and then fire the starting gun.

The time between the gun and first kick against the starting block is measured electronically, via sensors built in the gun and the blocks. A reaction time less than 0.1s is considered a false start. The 0.1-second interval accounts for the sum of the time it takes for the sound of the starter's pistol to reach the runners' ears, and the time it takes for a human to react to it.

For many years a sprinter was disqualified if responsible for two false starts individually. However, this rule was allowing some major races to be restarted so many times that the sprinters started to lose focus. The new rule is that, after one false start, anyone responsible for a subsequent false start is disqualified immediately. This rule has led to some sprinters deliberately false-starting to gain a psychological advantage: an individual with a slower reaction time might false-start, forcing the faster starters to wait and be sure of hearing the gun for the subsequent start, thereby losing some of their advantage.

Climatic conditions

Climatic conditions are a crucial factor for good performances in the 100 m. Air resistance is the primary climatic factor in sprint performances. A strong head wind is very detrimental to performance, while a tail wind can improve performances significantly. For this reason, a maximum tail wind of 2.0m/s is allowed for a 100m performance to be considered eligible for records, or "wind legal". Furthermore, sprint athletes perform better at high altitudes because of the thinner air, which provides less air resistance. While there are no limitations on altitude, performances made at altitudes greater than 1000 m above sea level are marked with an "A".[2]

2 9.69 +2.0 Tyson Gay United States September 20, 2009 Shanghai
−0.1 Yohan Blake Jamaica August 23, 2012 Lausanne
4 9.72 +0.2 Asafa Powell Jamaica September 2, 2008 Lausanne

9 9.80 +1.3 Steve Mullings Jamaica June 4, 2011 Eugene
10 9.82 +1.7 Richard Thompson Trinidad and Tobago June 21, 2014 Port of Spain


Notes

  • Usain Bolt's 9.63 in London on August 5, 2012 is currently the Olympic record.
  • Justin Gatlin ran 9.77 in Doha on May 12, 2006, which was at the time ratified as a world record. However, the performance was annulled in 2007 after he failed a doping test in April 2006.
  • Ben Johnson ran 9.79 at Seoul on September 24, 1988, but he was disqualified after he tested positive for stanozolol after the race. He subsequently admitted to drug use between 1981 and 1988, and his time of 9.83 in Rome on August 30, 1987 was invalidated. Carl Lewis's 9.92 in the Seoul race was therefore recognized as the world record, and his two prior runs of 9.93 were seen as having equalled the previous world record.
  • Tim Montgomery's time (9.78 in Paris on September 14, 2002) was invalidated following his indictment in the BALCO scandal on drug use and drug trafficking charges. The time had stood as the world record until Asafa Powell first ran 9.77.
