100-metre Dash
The 100 metres, or 100-meter dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, the dash is one of the most popular and prestigious events in the sport of athletics. It has been contested at the Summer Olympics since 1896 for men and since 1928 for women. The inaugural World Championships were in 1983. The reigning 100 m Olympic or world champion is often named "the fastest man or woman in the world". 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. 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. 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. The runners move to the start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athletics At The 2012 Summer Olympics – Men's 100 Metres
The men's 100 metres competition at the 2012 Summer Olympics in London, United Kingdom was held at the Olympic Stadium on 4–5 August 2012. Seventy-four athletes from 61 nations competed. Each nation was limited to 3 athletes per rules in force since the 1930 Olympic Congress. The competition comprised four rounds: a preliminary round for entrants without the minimum qualifying standard, a heats round, followed by three semi-finals of eight athletes each, which then reduced to eight athletes for the final. Just before the start of the final, a spectator threw a plastic bottle into Tyson Gay's lane, intended to hit Usain Bolt who was three lanes outside in Lane 7. The race was unaffected, and Bolt became the second man in history to defend a 100m Olympic title. The spectator, later identified as Ashley Gill-Webb, was soon arrested after he was struck on the head by Dutch judoka and bronze medalist Edith Bosch, whom he happened to be sitting next to.

Fred Kerley
Fredrick Lee Kerley (born May 7, 1995) is an American track and field sprinter known primarily for competing in the 400 meters distance but more recently the 100 meters and 200 meters. He has earned several medals at the World Championships in the 400 m and 4 × 400 m relay including an individual bronze and a relay gold at the 2019 edition. Kerley claimed 100m gold in the 2022 edition. Kerley's personal best time of 43.64 seconds makes him the eighth fastest man in history over 400 m. During the pandemic, Kerley chose to focus on the 100 meters during the Olympic cycle to improve his basic speed for future attempts at a sub-43 400 m. The decision to move down paid off as he won the silver medal in the 100 m at the 2020 Tokyo Olympics with a 9.84 performance; His personal best time of 9.76 makes him the sixth fastest man in history over the straightaway sprint. Kerley is one of only 3 men along with Michael Norman and Wayde van Niekerk to go sub 10 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
False Start
In sports, a false start is a disallowed start, usually due to a movement by a participant before (or in some cases after) being signaled or otherwise permitted by the rules to start. Depending on the sport and the event, a false start can result in a penalty against the athlete's or team's field position, a warning that a subsequent false start will result in disqualification, or immediate disqualification of the athlete from further competition. False starts are common in racing sports (such as swimming, track, sprinting, and motor sports), where differences are made by fractions of a second and where anxiety to get the best start plays a role in the athletes' behavior. A race that is started without a false start is referred to as a ''fair start'' or ''clean start''. In sports Association Football (soccer) Football games cannot be restarted unless certain conditions are met. For example, both teams need to be in their own half of the field for the start of the game or res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

7 (seven) is the natural number following 6 and preceding 8. It is the only prime number preceding a cube. As an early prime number in the series of positive integers, the number seven has greatly symbolic associations in religion, mythology, superstition and philosophy. The seven Classical planets resulted in seven being the number of days in a week. It is often considered lucky in Western culture and is often seen as highly symbolic. Unlike Western culture, in Vietnamese culture, the number seven is sometimes considered unlucky. It is the first natural number whose pronunciation contains more than one syllable. Evolution of the Arabic digit In the beginning, Indians wrote 7 more or less in one stroke as a curve that looks like an uppercase vertically inverted. The western Ghubar Arabs' main contribution was to make the longer line diagonal rather than straight, though they showed some tendencies to making the digit more rectilinear. The eastern Arabs developed the digit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of World Records In Athletics
World records in athletics are ratified by World Athletics. Athletics records comprise the best performances in the sports of track and field, road running and racewalking. Records are kept for all events contested at the Olympic Games and some others. Unofficial records for some other events are kept by track and field statisticians. The only non-metric track distance for which official records are kept is the mile run. Criteria The criteria which must be satisfied for ratification of a world record are defined by World Athletics in Part III of the Competition Rules. These criteria also apply to national or other restricted records and also to performances submitted as qualifying marks for eligibility to compete in major events such as the Olympic Games. The criteria include: * The dimensions of the track and equipment used must conform to standards. In road events, the course must be accurately measured, by a certified measurer. * Except in road events (road running and race ...

10-second Barrier
The 10-second barrier is the physical and psychological barrier of completing the 100 metres sprint in under ten seconds. The achievement is traditionally regarded as the hallmark of a world-class male sprinter. Its significance has become less important since the late 1990s, as an increasing number of runners have surpassed the ten seconds mark. The current men's world record holder is Usain Bolt, who ran a 9.58 at the 2009 IAAF World Championship competition. History For sprints, World Athletics maintains that world records and other recognised performances require: a wind assistance of not more than two metres per second () in the direction of travel; fully automatic timing (FAT) to one hundredth of a second; and no use of performance-enhancing substances. Wind gauge malfunctions or infractions may invalidate a sprinter's time. Hand timing Prior to 1977, FAT was not required for IAAF official timings. Times were recorded manually to one tenth of a second; three official ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isometric Exercise
An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint. The term "isometric" combines the Greek words ''isos'' (equal) and ''-metria'' (measuring), meaning that in these exercises the length of the muscle and the angle of the joint do not change, though contraction strength may be varied. This is in contrast to ''isotonic contractions'', in which the contraction strength does not change, though the muscle length and joint angle do. The three main types of isometric exercise are isometric presses, pulls, and holds. They may be included in a strength training regime in order to improve the body’s ability to apply power from a static position or, in the case of isometric holds, improve the body’s ability to maintain a position for a period of time. Considered as an action, isometric presses are also of fundamental importance to the body’s ability to prepare itself to perform immediately s ...

Starting Blocks
Starting blocks are a device used in the sport of track and field by sprint athletes to brace their feet against at the start of a race so they do not slip as they stride forward at the sound of the starter's pistol. The blocks also enable the sprinters to adopt a more efficient starting posture and isometrically preload their muscles in an enhanced manner. This allows them to start more powerfully and increases their overall sprint speed capability. For most levels of competition, including the whole of high-level international competition, starting blocks are mandatory equipment for the start of sprint races. IAAF Rule 161 Their invention is credited to Australian Charlie Booth and his father in 1929. Prior to this, runners would dig holes in the dirt track. Trowels were provided at the start of races. This was not the most consistent or stable system. It also was destructive to the track surface with the holes having to be filled for subsequent runners. When George Simpson be ...

Starter's Pistol
A starting pistol or starter pistol is a blank handgun that is fired to start track and field races, as well as competitive swimming races at some meets. Starter guns cannot fire real ammunition without first being extensively modified: Blank shells or caps are used to prevent expelling projectiles, and only a small amount of smoke can be seen when shot. In most places, trying to modify the replica is illegal. Starting pistols may also include modified versions of standard pistols incapable of firing bullets, most commonly achieved by welding an obstruction into the barrel. This is less common nowadays, especially in Western countries. When electronic timing is used, a sensor is often affixed to the gun, which sends an electronic signal to the timing system upon firing. For deaf competitors or for modern electronic systems, a light may be used instead. Use in races The sound of the gun going off serves as the signal for the athletes to begin the event. An issue with the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Straight
{{about, the element of a track, , Straight (other) In many forms of racing, a straight or stretch is a part of the race track in which the competitors travel in a straight line for any significant time, as opposed to a bend or curve. The term is used in horse racing, motor racing and track and field athletics. In athletics, a typical 400 m track features two straights and two bends. The final straight before the finish line is known as the home straight, or the pit straight in Formula One, while the other is known as the back straight. In motor racing, both the pit lane and finish line are often located on the longest straight on the circuit. A notable exception is the 6 km Mulsanne Straight The Mulsanne Straight (''Ligne Droite des Hunaudières'' in French) is the name used in English for a formerly long straight of the Circuit de la Sarthe around which the 24 Hours of Le Mans auto race takes place. Since 1990, the straight is int ... at Le Mans, which is at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Track
An all-weather running track is a rubberized, artificial running surface for track and field athletics. It provides a consistent surface for competitors to test their athletic ability unencumbered by adverse weather conditions. Historically, various forms of dirt, Rocks, sand, and crushed cinders were used. Many examples of these varieties of track still exist worldwide. Surfaces Starting in the late 1950s, artificial surfaces using a combination of rubber and asphalt began to appear. An artificial warm-up track was constructed for the 1956 Summer Olympics in Melbourne, Australia. During the 1960s many of these tracks were constructed; examples still exist today. In the mid-1960s Tartan tracks were developed, surfaced with a product by 3M. The name ''Tartan'' is a trademark, but it is sometimes used as a genericized trademark. This process was the first to commercialize a polyurethane surface for running tracks, though it was originally conceived for horse racing. Many T ...

400 Metres
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics (sport), athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete. Like other sprint disciplines, the 400 m involves the use of starting blocks. The runners take up position in the blocks on the 'ready' command, adopt a more efficient starting posture which Isometric exercise#Isometric presses as preparation for explosive power movements, isometrically preloads their muscles on the 'set' command, and stride forwards from the block ...
