400-meter Dash
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the 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 (1,760 yards) 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 isometrically preloads their muscles on the "set" command, and stride forwards from the blocks upon hearing the starter's pistol. The blocks allow the runners to begin more powerf ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Isometric Exercise
An isometric exercise is an 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 subsequent pow ...

Michael Johnson (athlete)
Michael Duane Johnson (born September 13, 1967) is an American sprinter who became Olympic Champion four times, and World Champion eight times in the span of his career. He held the world and Olympic records in the 200 m and 400 m, as well as the world record in the indoor 400 m. He also once held the world's best time in the 300 m.

200 metres
The 200 metres, or 200-meter dash, is a sprint running event. On an outdoor 400-metre racetrack, the race begins on the curve and ends on the home straight, so a combination of techniques is needed to successfully run the race. A slightly shorter race, called the '' stadion'' and run on a straight track, was the first recorded event at the ancient Olympic Games. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes predominantly rely on anaerobic energy system during the 200 m sprint. Similarly to other sprint distances, the 200 m begins from the starting blocks. When the sprinters adopt the 'set' position in the blocks they are able to adopt a more efficient starting posture and isometrically preload their muscles. This enables them to stride forwards more powerfully when the race begins and start faster. In the United States and elsewhere, athletes previously ran the 220-yard dash (201.168 m) instead of the 200 m (2 ...

Oscar Pistorius
Oscar Leonard Carl Pistorius ( , ; born 22 November 1986) is a South African double amputee, former professional sprinter, and convicted murderer. He was the 10th athlete to compete at both the Paralympic Games and Olympic Games. Pistorius ran in both nondisabled sprint events and in sprint events for below-knee amputees. Both of his legs were amputated below the knee when he was 11 months old as a result of a congenital defect; he was born missing the outside of both feet and both fibulas. Pistorius' athletic career ended when he was convicted of murder in 2015. He was first convicted of culpable homicide of his then-girlfriend, Reeva Steenkamp, which was subsequently upgraded to murder upon appeal. After becoming a Paralympic champion, Pistorius attempted to enter nondisabled international competitions, over persistent objections by the International Association of Athletics Federations (IAAF) and arguments that his artificial limbs gave an unfair advantage.
