![]() The following graph shows Bolt’s sectional speed for every 10 meters when he set the world record. Maintaining maximum middle-stage speeds and reducing deceleration is the key to breaking records When Bolt achieved the world record time of 9.58 seconds, his average step rate was 4.271 steps (40.92 strides) and average stride 244.4cm. Which is more important depends on the physical abilities of the individual athlete. Speed is expressed as the product of step rate and stride. Sustain speed while maintaining stride and posture. Reach maximum sprinting speed with increasing stride. Secondary acceleration: 20 to 50 m section.From a crouching stance, accelerate rapidly while gradually raising the upper body and quickly increasing the step rate. Initial acceleration: the first 10 to 20 m.The 100-meter dash is generally analyzed in the following four phases: From a sports science perspective, there is yet room for improvement in step rate (number of steps per second), stride (step length), and power distribution. While the world record for the 100-meter dash is likely approaching a physical limit, the 9.4-second mark is said to be possible still. Speed is the product of step rate and stride However, with Elaine Thompson-Herah (Jamaica) setting a near-world record of 10.54 seconds in 2021, hopes are high for the next record-breaker. This best record has remained unbroken for over 30 years, with the world’s top athletes hovering around the 10.6-second range since. Since 1977 when Marlies Oelsner-Göhr (East Germany) first broke the 11-second barrier, Evelyn Ashford (USA) recorded 10.76 seconds in 1984, and Florence Griffith-Joyner achieved 10.49 seconds four years later in 1988. The progression of world records for women’s 100-meter dash is shown below (as of March 2022). The women’s 100-meter record of 10.49 seconds by Griffith-Joyner’s still stands The 9.60-second barrier had not been surpassed for more than a decade, signifying how outstanding Bolt’s record of 9.58 seconds is. The progression of world records for men’s 100-meter dash is shown below (as of March 2022). In 2009, Usain Bolt (Jamaica) set a remarkable world record of 9.58 seconds at the 2009 World Athletics Championships in Berlin. Since then, world records have been set almost every few years. The adoption of all-weather tracks, the development of spiked shoes, and improved training methods incorporating sports science are said to have contributed significantly to record-breaking performance. The winning time at the first Athens Olympics (1896) was 12.0 seconds, which means it took about a century to shorten the 100-meter world record by approximately 2 seconds. ![]() The 10-second barrier, which had stood for a long time, was broken by Jim Hines (USA) in 1968 (9.95A, A for high altitude), and again in 1991 by Carl Lewis (USA), who achieved the 9.8-second mark. The first official record for the men’s 100-meter dash was 10.6 seconds, recorded at the 1912 Stockholm Olympics (during the preliminary round recorded manually with a stopwatch at the time). The current men's world record is 9.58 seconds, set by Jamaica's Usain Bolt in 2009, while the women's world record is 10.49 seconds set by American Florence Griffith-Joyner in 1988.100 meters is a track-and-field highlight event that decides the “Fastest Human”Īlong with the ultimate endurance-testing marathon, the 100-meter dash, or 100 meters, is considered a highlight event in track and field that determines the fastest human being. The 10-second barrier has historically been a barometer of fast men's performances, while the best female sprinters take eleven seconds or less to complete the race. Their speed then slows towards the finish line. Sprinters typically reach top speed after somewhere between 50 and 60 m. A race-official then fires the starter's pistol to signal the race beginning and the sprinters stride forwards from the blocks. The following instruction, to adopt the 'set' position, allows them to adopt a more efficient starting posture and isometrically preload their muscles: this will help them to start faster. ![]() The runners move to the starting blocks when they hear the 'on your marks' instruction. There are three instructions given to the runners immediately before and at the beginning of the race: "on your marks," "set," and the firing of the starter's pistol. ![]() On an outdoor 400-metre running track, the 100 m is held on the home straight, with the start usually being set on an extension to make it a straight-line race. Fred Kerley and Shelly-Ann Fraser-Pryce are the reigning world champions Marcell Jacobs and Elaine Thompson-Herah are the men's and women's Olympic champions. The reigning 100 m Olympic or world champion is often named "the fastest man or woman in the world". Start of the men's 100 metres final at theįlorence Griffith-Joyner 10.49 (1988)
