Long Jump
The long jump is a track and field event in which athletes combine speed, strength and agility in an attempt to leap as far as possible from a takeoff point. Along with the triple jump, the two events that measure jumping for distance as a group are referred to as the "horizontal jumps". This event has a history in the ancient Olympic Games and has been a modern Olympic event for men since the first Olympics in 1896 and for women since 1948. Rules At the elite level, competitors run down a runway (usually coated with the same All-weather running track, rubberized surface as running tracks, crumb rubber or vulcanized rubber, known generally as an all-weather track) and jump as far as they can from a wooden or synthetic board, 20 centimetres or 8 inches wide, that is built flush with the runway, into a pit filled with soft damp sand. If the competitor starts the leap with any part of the foot past the foul line, the jump is declared a foul and no distance is recorded. ...

Para-athletics Classification
Para-athletics classification is a system to determine which athletes with disabilities may compete against each other in para-athletics events. Classification is intended to group together athletes with similar levels of physical ability to allow fair competition. Classification was created and is managed by the International Paralympic Committee (IPC), which is regularly published via its ''IPC Athletics Classification Handbook''. People with physical, vision and intellectual disabilities are eligible to compete in this sport at the Summer Paralympics. The classification for this sport was created during the 1940s and for much of its early history was a medical condition based classification system. The classification system has subsequently become a functional mobility based one, and is moving towards an evidence-based classification system. Each class has a code consisting of a letter and two digits, with the letter being either "T" or "F" (indicating track or field events) and ...

All-weather 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 1954, 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 Tartan trac ...

Halteres (ancient Greece)
Halteres (; , from "ἅλλομαι" - ''hallomai'', "leap, spring"; cf. "ἅλμα" - ''halma'', "leaping") were a type of kettlebells used in ancient Greece. In ancient Greek sports, halteres were used as lifting weights,Norman Gardiner, ''Athletics in the Ancient World'', Dover, 2002, oGoogle books/ref> and also as weights in their version of the long jump. Halteres were held in both hands to allow an athlete to jump a greater distance; they may have been dropped after the first or second jump. The athlete would swing the weights backwards and forwards just before take-off, thrust them forwards during take-off, and swing them backwards just before releasing them and landing. Halteres were made of stone or metal and weighed between . They added about to a long jump. History Recognized as the Greek equivalent of modern-day kettlebells, the halteres served multiple uses from training to competition. Ancient Greek records show evidence of the halteres dating to as far back ... [...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 ...

Halteres From Ancient Greece
''Halteres'' (; singular ''halter'' or ''haltere'') (from , hand-held weights to give an impetus in leaping) are a pair of small club-shaped organs on the body of two orders of flying insects that provide information about body rotations during flight. Insects of the large order Diptera (flies) have halteres which evolved from a pair of ancestral hindwings, while males of the much smaller order Strepsiptera (stylops)Merriam-Webster: stylops broadly: an insect of the order Strepsiptera/ref> have halteres which evolved from a pair of ancestral forewings. Halteres oscillate rapidly along with the wings and operate like vibrating structure gyroscopes: any rotation of the plane of oscillation causes a force on the vibrating halteres by the Coriolis effect. The insect detects this force with sensory organs called campaniform sensilla and chordotonal organs located at the base of the halteres and uses this information to interpret and correct its position in space. Halteres provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wind Assistance
In track and field, wind assistance is the benefit that an athlete receives during a race or event as registered by a wind gauge. Wind is one of many forms of weather that can affect sport. Due to a tailwind helping to enhance the speed of the athlete in events like certain sprint races ( 100 and 200 metres), 100/110 metres hurdles, the triple jump and the long jump, there is a limit to how much wind assistance the athlete may compete under if the performance is to establish a record. If a tail wind exceeds the result cannot be registered as a record on any level. However, the results within that competition are still valid because all athletes in said race would receive similar assistance, and in field events it is just random circumstance at the moment of the attempt. The wind assistance maximums are only in regard to the validation of a record. The exceptions are the combined events like heptathlon and decathlon. Here, the total score may be accepted even though some of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IAAF World Championships In Athletics
The World Athletics Championships, known as the IAAF World Championships in Athletics until 2019, are a biennial athletics competition organized by World Athletics, formerly International Association of Athletics Federations. Alongside Olympic Games, the championships represents the highest level of senior international outdoor athletics competition for track and field athletics globally, including marathon running and race walking. Separate World Championships are held by World Athletics for certain other outdoor events, including cross-country running and half-marathon, as well as indoor and age-group championship. The World Championships were started in 1976 in response to the International Olympic Committee dropping the men's 50 km walk from the Olympic programme for the 1976 Montreal Olympics, despite its constant presence at the games since 1932. The IAAF chose to host its own world championship event, a month and a half after the Olympics. It was the first World Ch ...

Diamond League
The Diamond League is an annual series of elite track and field athletic competitions comprising fifteen invitational athletics meetings. The series sits in the top tier of the World Athletics one-day meet competitions. The inaugural season was in 2010. It was designed to replace the IAAF Golden League, which had been held annually since 1998. The full sponsorship name is the Wanda Diamond League, the result of an agreement with Wanda Group that was announced in December 2019. While the Golden League was formed to increase the profile of the leading European athletics competitions, the Diamond League's aim is to "enhance the worldwide appeal of athletics by going outside Europe for the first time." In addition to the original Golden League members (except Berlin) and other traditional European competitions, the series now includes events in China, Qatar, Morocco, and the United States. Beginning in March 2022, after the 2022 Russian invasion of Ukraine, the Diamond League exclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
High-speed Camera
A high-speed camera is a device capable of capturing moving images with exposures of less than second or frame rates in excess of 250 frames per second. It is used for recording fast-moving objects as photographic images onto a storage medium. After recording, the images stored on the medium can be played back in slow motion. Early high-speed cameras used photographic film to record the high-speed events, but have been superseded by entirely electronic devices using an image sensor (e.g. a charge-coupled device (CCD) or a MOS active pixel sensor (APS)), typically recording over 1 000 frames per second onto DRAM, to be played back slowly to study the motion for scientific study of transient phenomena. Overview A high-speed camera can be classified as: # A high-speed film camera which records to film, # A high-speed video camera which records to electronic memory, # A high-speed framing camera which records images on multiple image planes or multiple locations on the same im ...
