Sprinting
Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of phosphocreatine stores in muscles, and perhaps secondarily to excessive metabolic acidosis as a result of anaerobic glycolysis. In athletics and track and field, sprints (or dashes) are races over short distances. They are among the oldest running competitions, being recorded at the Ancient Olympic Games. Three sprints are currently held at the modern Summer Olympics and outdoor World Championships: the 100 metres, 200 metres, and 400 metres. At the professional level, sprinters begin the race by assuming a crouching position in the starting blocks before driving forward and gradually moving into an u ...

Track And Field
Track and field (or athletics in British English) is a sport that includes Competition#Sports, athletic contests based on running, jumping, and throwing skills. The name used in North America is derived from where the sport takes place, a running track and a grass field for the throwing and some of the jumping events. Track and field is categorized under the umbrella sport of athletics, which also includes road running, cross country running and racewalking. Though the sense of "athletics" as a broader sport is not used in American English, outside of the United States the term ''athletics'' can either be used to mean just its track and field component or the entirety of the sport (adding road racing and cross country) based on context. The foot racing events, which include sprint (running), sprints, middle-distance running, middle- and long-distance running, long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time.

Usain Bolt 2012 Olympics 1
Usain St. Leo Bolt (; born 21 August 1986) is a Jamaican retired sprinter who is widely regarded as the greatest sprinter of all time. He is an eight-time Olympic gold medalist and the world record holder in the 100 metres, 200 metres, and 4 × 100 metres relay. Bolt is the only sprinter to win Olympic 100 m and 200 m titles at three consecutive Olympics (2008, 2012, and 2016). He also won two 4 × 100 relay gold medals. He gained worldwide fame for his double sprint victory in world record times at the 2008 Beijing Olympics, which made him the first person to hold both records since fully automatic time became mandatory. An eleven-time World Champion, he won consecutive World Championship 100 m, 200 m and 4 × 100 metres relay gold medals from 2009 to 2015, with the exception of a 100 m false start in 2011. He is the most successful male athlete of the World Championships. Bolt is the first athlete to win four World Championship titles in ...

Running
Running is a method of terrestrial locomotion by which humans and other animals move quickly on foot. Running is a gait with an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, a slower form of movement where at least one foot is always in contact with the ground, the legs are kept mostly straight, and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of Spring mass system, spring-mass mechanics is that changes in Kinetic energy, kinetic and potential energy within a stride co-occur, with energy storage accomplished by springy tendons and passive muscle elasticity. The term "running" can refer to a variety of speeds ranging from jogging to Sprint (running), sprinting. Running in humans is associated with improved health and life expect ...

100 Metres
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. 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 starting blocks when they hear the 'on your marks' instruction. 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. A race-official then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Stadion Race
''Stadion'' or ''stade'' () was an ancient running event and also the faciliity in which it took place, as part of Panhellenic Games including the Ancient Olympic Games. The event was one of the five major Pentathlon events and the premier event of the ''gymnikos agon'' (γυμνικὸς ἀγών "nude competition"). From the years 776 to 724 BC, the ''stadion'' was the only event at the Olympic Games. The victor (the first of whom was Coroebus of Elis) gave his name to the entire four-year Olympiad, allowing modern knowledge of nearly all of them. The ''stadion'' was named after the facility in which it took place. This word became ''stadium'' in Latin, which became the English "stadium". The race also gave its name to the unit of length, the stadion. There were other types of running events, but the ''stadion'' was the most prestigious; the winner was often considered to be the winner of an entire Games. Though a separate event, the ''stadion'' was also part of the ancie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Diaulos (running Race)
The ''diaulos'' (, meaning "double pipe") was a double- stadion footrace of approximately , introduced in the 14th Olympiad of the ancient Olympic Games in 724 BC. The exact length of the race varied by venue due to the lack of standardized Greek measurements. For instance, the Stadium at Olympia measured , whereas the Stadium of Delphi was long. Scholars debate whether runners turned around a single post or used individual turning posts (''kampteres'') on the return leg. A single turning post could have disadvantaged runners in outer lanes, potentially adding to their distance. In contrast, inscriptions from Delphi mention "turning-posts" in the plural, and archaeological findings at Nemea also support the use of individual posts. Functionally, the diaulos resembled the modern 400-metre race. However, distinguishing it from the stadion race in ancient vase paintings is difficult due to visual similarities. One notable exception is a fragment of a Panathenaic amp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Olympiad
An olympiad (, ''Olympiás'') is a period of four years, particularly those associated with the Ancient Olympic Games, ancient and Olympic Games, modern Olympic Games. Although the ancient Olympics were established during Archaic Greece, Greece's Archaic Era, it was not until Hippias of Elis, Hippias that a consistent list was established and not until Ephorus of Cyme, Ephorus in the Hellenistic period that the first recorded Olympic contest was used as a Epoch (reference date), calendar epoch. Ancient authors agreed that other Olympics had been held before the race won by Coroebus of Elis, Coroebus but disagreed on how many; the convention was established to place Coroebus's victory at a time equivalent to the summer of 776 BC, 776 BC in the Proleptic Julian calendar, and to treat it as Year 1 of Olympiad 1. Olympiad 2 began with the next games in the summer of 772 BC. Thus, for N less than 195, Olympiad N is reckoned as having started in the year 780-(4\times N) ...

Ancient Olympic Games
The ancient Olympic Games (, ''ta Olympia''.), or the ancient Olympics, were a series of Athletics (sport), athletic competitions among representatives of polis, city-states and one of the Panhellenic Games of ancient Greece. They were held at the Panhellenic sanctuary, Panhellenic religious sanctuary of Olympia, Greece, Olympia, in honor of Zeus, and the Greeks gave them a aition, mythological origin. The originating Olympic Games are traditionally dated to 776 BC. The games were held every four years, or Olympiad, which became a unit of time in historical chronologies. These Olympiads were referred to based on the winner of their ''Stadion (running race), stadion'' sprint, e.g., "the third year of the eighteenth Olympiad when Ladas of Argos won the ''stadion''". They continued to be celebrated when Greece came under Greece in the Roman era, Roman rule in the 2nd century BC. Their last recorded celebration was in AD 393, under the emperor Theodosius I, but archaeological evidenc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
1896 Summer Olympics
The 1896 Summer Olympics (), officially known as the Games of the I Olympiad () and commonly known as Athens 1896 (), were the first international Olympic Games held in modern history. Organised by the International Olympic Committee (IOC), which had been created by French aristocrat Pierre de Coubertin, the event was held in Athens, Greece, from 6 to 15 April 1896. Fourteen nations (according to the IOC, though the number is subject to interpretation) and 241 athletes (all males; this number is also disputed) took part in the games. Participants were all European or living in Europe, with the exception of the United States team, and over 65% of the competing athletes were Greek. Winners were given a silver medal, while runners-up received a copper medal. Retroactively, the IOC has designated the top three finishers in each event as gold, silver, and bronze medalists. Ten of the 14 participating nations earned medals. On April 6, 1896, American James Connolly became the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
1928 Summer Olympics
The 1928 Summer Olympics (), officially the Games of the IX Olympiad (), was an international multi-sport event that was celebrated from 28 July to 12 August 1928 in Amsterdam, Netherlands. The city of Amsterdam had previously bid for the 1920 and 1924 Olympic Games. Still, it was obliged to give way to war-torn Antwerp in Belgium for the 1920 Summer Olympics, 1920 Games and Pierre de Coubertin's Paris for the 1924 Summer Olympics, 1924 Games. The only other candidate city for the 1928 Olympics was Los Angeles, which would eventually be selected to host the Olympics four years later. In preparation for the 1932 Summer Olympics, the United States Olympic Committee reviewed the costs and revenue of the 1928 Games. The committee reported a total cost of United States dollar, US$1.183 million with receipts of US$1.165 million, giving a negligible loss of US$18,000, which was a considerable improvement over the 1924 Games. The United States won the most gold and medals over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Imperial Measurement
The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial system developed from earlier English units as did the related but differing system of customary units of the United States. The imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but imperial units are still used alongside metric units in the United Kingdom and in some other parts of the former empire, notably Canada. The modern UK legislation defining the imperial system of units is given in the Weights and Measures A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
