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 ...

Track And Field
Track and field is a sport that includes athletic contests based on running, jumping, and throwing skills. The name 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. The foot racing events, which include sprints, middle- and long-distance events, racewalking, and hurdling, are won by the athlete who completes it in the least time. The jumping and throwing events are won by those who achieve the greatest distance or height. Regular jumping events include long jump, triple jump, high jump, and pole vault, while the most common throwing events are shot put, javelin, discus, and hammer. There are also "combined events" or "multi events", such as the pentathlon consisting of five events, heptathlon consisting of seven events, and decathlon cons ...

Running
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where 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 mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting. Running in humans is associated with improved health and life expectancy. It is assumed that the ancestors of humanki ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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 th ...

Stadion Race
''Stadion'' or ''stade'' ( grc, στάδιον) was an ancient running event, part of the Ancient Olympic Games and the other Panhellenic Games. It was one of the five major Pentathlon events. It was the premier event of the ''gymnikos agon'' (γυμνικὸς ἀγών "nude competition"). History From the years 776 to 724 BC, the ''stadion'' was the only event that took place at the Olympic Games. The victor gave his name to the entire four-year Olympiad, which has allowed scholars to know the names of nearly every ancient Olympic stadion winner. The ''stadion'' was named after the building in which it took place, also called the ''stadion''. This word became ''stadium'' in Latin, which became the English word 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 ''sta ...

Diaulos (running Race)
Diaulos ( Greek: Δίαυλος, English translation: "double pipe") was a double- stadion race, , introduced in the 14th Olympiad of the ancient Olympic Games (724BC). The length of each foot race varied depending on the length of the stadium. This was because the Greek foot varied widely from one locality to another, for example the stadium at Olympia was but at Delphi it was long. Scholars debate whether or not the runners had individual "turning" posts for the return leg of the race, or whether all the runners approached a common post, turned, and then raced back to the starting line. Although at Delphi an inscription referenced "turning-posts" as opposed to "turning-post", which suggests each runner had their own turning post, to prevent an outside runner from losing . These were called ''kampteres''. Archaeological evidence at Nemea Nemea (; grc, Νεμέα; grc-x-ionic, Νεμέη) is an ancient site in the northeastern part of the Peloponnese, in Greece. Formerl ...

Olympiad
An olympiad ( el, Ὀλυμπιάς, ''Olympiás'') is a period of four years, particularly those associated with the ancient and modern Olympic Games. Although the ancient Olympics were established during Greece's Archaic Era, it was not until Hippias that a consistent list was established and not until Ephorus in the Hellenistic period that the first recorded Olympic contest was used as a calendar epoch. Ancient authors agreed that other Olympics had been held before the race won by Coroebus but disagreed on how many; the convention was established to place Coroebus's victory at a time equivalent to the summer of 776 in the Gregorian calendar and to treat it as Year 1 of Olympiad 1. Olympiad 2 began with the next games in the summer of 772 . Thus, for N less than 195, Olympiad N is reckoned as starting in the year 780-(4\times N) and ending four years later. For N greater than or equal to 195, Olympiad N started in (4\times N)-779 and ended four yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Olympic Games
The ancient Olympic Games (Ὀλυμπιακοὶ ἀγῶνες; la, Olympia, neuter plural: "the Olympics") were a series of athletic competitions among representatives of city-states and were one of the Panhellenic Games of Ancient Greece. They were held in honor of Zeus, and the Greeks gave them a 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. They continued to be celebrated when Greece came under Roman rule, 2nd century BC. Their last recorded celebration was in AD 393, under the emperor Theodosius I, but archeological evidence indicates that some games were still held after this date.Hamlet, Ingomar. "Theodosius I. And The Olympic Games". Nikephoros 17 (2004): pp. 53-75. The games likely came to an end under Theodosius II, possibly in connection with a fire that burned down the temple of the Olympian Zeus during his rei ...

1896 Summer Olympics
The 1896 Summer Olympics ( el, Θερινοί Ολυμπιακοί Αγώνες 1896, Therinoí Olympiakoí Agónes 1896), officially known as the Games of the I Olympiad ( el, Αγώνες της 1ης Ολυμπιάδας, Agónes tis 1is Olympiádas) and commonly known as Athens 1896 ( el, Αθήνα 1896), was 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, it 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. 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 converted these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1928 Summer Olympics
The 1928 Summer Olympics ( nl, Olympische Zomerspelen 1928), officially known as the Games of the IX Olympiad ( nl, Spelen van de IXe Olympiade) and commonly known as Amsterdam 1928, 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, but was obliged to give way to war-torn Antwerp in Belgium for the 1920 Games and Pierre de Coubertin's Paris for the 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 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.

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 Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
