Track and field athletics

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 consisting of ten events. In these, athletes participate in a combination of track and field events. Most track and field events are individual sports with a single victor; the most prominent team events are relay races, which typically feature teams of four. Events are almost exclusively divided by gender, although both the men's and women's competitions are usually held at the same venue. Recently, “mixed” relay events have been introduced into meets, whereby two men and two women make up the four-person team. If a race has too many people to run all at once, preliminary heats will be run to narrow down the field of participants.

Track and field is one of the oldest sports. In ancient times, it was an event held in conjunction with festivals and sports meets such as the Ancient Olympic Games in Greece. In modern times, the two most prestigious international track and field competitions are the athletics competition at the Olympic Games and the World Athletics Championships. World Athletics, formerly known as the ''International Association of Athletics Federations'' (''IAAF''), is the international governing body for the sport of athletics.

Records are kept of the best performances in specific events, at world, continental, and national levels, right down to a personal level. However, if athletes are deemed to have violated the event's rules or regulations, they are disqualified from the competition and their marks are erased.

In the United States, the term track and field may refer to other athletics events, such as cross country, the marathon, and road running, rather than strictly track-based events.

History

The sport of track and field has its roots in human prehistory. Track and field style events are among the oldest of all sporting competitions, as running, jumping and throwing are natural and universal forms of human physical expression. The first recorded examples of organized track and field events at a sports festival are the Ancient Olympic Games. At the first Games in 776 BC in Olympia, Greece, only one event was contested: the stadion footrace.Instone, Stephen (15 November 2009)
The Olympics: Ancient versus Modern
BBC. Retrieved on 23 March 2010. The scope of the Games expanded in later years to include further running competitions, but the introduction of the Ancient Olympic pentathlon marked a step towards track and field as it is recognized today—it comprised a five-event competition of the long jump, javelin throw, discus throw, stadion footrace, and wrestling.

Track and field events were also present at the Panhellenic Games in Greece around this period, and they spread to Rome in Italy around 201 BC. After the period of Classical antiquity (in which the sport was largely Greco-Roman influenced) new track and field events began developing in parts of Northern Europe in the Middle Ages. The stone put and weight throw competitions popular among Celtic societies in Ireland and Scotland were precursors to the modern shot put and hammer throw events. One of the last track and field events to develop was the pole vault, which stemmed from competitions such as the Fierljeppen contests in the Northern European Lowlands in the 18th century.

Discrete modern track and field competitions, separate from general sporting festivals, were first recorded in the 19th century. These were typically organised by educational institutions, military organisations and sports clubs as competitions between rival establishments.History – Introduction
. IAAF. Retrieved 25 March 2010. Competitions in the English public schools were conceived as human equivalents of horse racing, fox hunting and hare coursing, influenced by a Classics-rich curriculum. The Royal Shrewsbury School Hunt is the oldest running club in the world, with written records going back to 1831 and evidence that it was established by 1819. The school organised Paper Chase races in which runners followed a trail of paper shreds left by two "foxes"; even today RSSH runners are called "hounds" and a race victory is a "kill". The first definite record of Shrewsbury's (cross-country) Annual Steeplechase is in 1834, making it the oldest running race of the modern era. The school also lays claim to the oldest track and field meeting still in existence, originating in the Second Spring Meeting first documented in 1840. This featured a series of throwing and jumping events with mock horse races including the Derby Stakes, the Hurdle Race and the Trial Stakes. Runners were entered by "owners" and named as though they were horses. away and a decade later, the first Wenlock Olympian Games were held at Much Wenlock racecourse. Events at the 1851 Wenlock Games included a "half-mile foot race" (805 m) and a "leaping in distance" competition.

In 1865, Dr William Penny Brookes of Wenlock helped set up the National Olympian Association, which held their first Olympian Games in 1866 at The Crystal Palace in London. This national event was a great success, attracting a crowd of over ten thousand people. In response, that same year the Amateur Athletic Club was formed and held a championship for "gentlemen amateurs" in an attempt to reclaim the sport for the educated elite. Ultimately the "allcomers" ethos of the NOA won through and the AAC was reconstituted as the Amateur Athletic Association in 1880, the first national body for the sport of athletics. The AAA Championships, the ''de facto'' British national championships despite being for England only, have been held annually since 3 July 1880 with breaks only during two world wars and 2006–2008. The AAA was effectively a global governing body in the early years of the sport, codifying its rules for the first time.

Meanwhile, the United States began holding an annual national competition—the USA Outdoor Track and Field Championships—first held in 1876 by the New York Athletic Club. The establishment of general sports governing bodies for the United States (the Amateur Athletic Union in 1888) and France (the Union des sociétés françaises de sports athlétiques in 1889) put the sport on a formal footing and meant that international competitions became possible.

The establishment of the modern Olympic Games at the end of the 19th century marked a new high for track and field. The Olympic athletics programme, comprising track and field events plus a marathon race, contained many of the foremost sporting competitions of the 1896 Summer Olympics. The Olympics also consolidated the use of metric measurements in international track and field events, both for race distances and for measuring jumps and throws. The Olympic athletics programme greatly expanded over the next decades, and track and field contests remained among the Games' most prominent. The Olympics was the elite competition for track and field, and only amateur sportsmen could compete. Track and field continued to be a largely amateur sport, as this rule was strictly enforced: Jim Thorpe was stripped of his track and field medals from the 1912 Olympics after it was revealed that he had taken expense money for playing baseball, violating Olympic amateurism rules, before the 1912 Games. His medals were reinstated 29 years after his death.

That same year, the International Amateur Athletic Federation (IAAF) was established, becoming the international governing body for track and field, and it enshrined amateurism as one of its founding principles for the sport. The National Collegiate Athletic Association held their first Men's Outdoor Track and Field Championship in 1921, making it one of the most prestigious competitions for students, and this was soon followed by the introduction of track and field at the inaugural World Student Games in 1923. The first continental track and field competition was the 1919 South American Championships, which was followed by the European Athletics Championships in 1934.

Up until the early 1920s, track and field had been almost exclusively a male-only pursuit. Alice Milliat argued for the inclusion of women at the Olympics, but the International Olympic Committee refused. She founded the International Women's Sports Federation in 1921 and, alongside a growing women's sports movement in Europe and North America, the group initiated of the Women's Olympiad (held annually from 1921 to 1923). Working in conjunction with the English Women's Amateur Athletic Association (WAAA), the Women's World Games was held four times between 1922 and 1934, as well as a Women's International and British Games in London in 1924. These events ultimately led to the introduction of five track and field events for women in the athletics at the 1928 Summer Olympics. In China, women's track and field events were being held in the 1920s, but were subject to criticism and disrespect from audiences. National women's events were established in this period, with 1923 seeing the First British Track & Field championships for women and the Amateur Athletic Union (AAU) sponsoring the First American Track & Field championships for women. Also in 1923, physical education advocate Zhang Ruizhen called for greater equality and participation of women in Chinese track and field. The rise of Kinue Hitomi and her 1928 Olympic medal for Japan signified the growth of women's track and field in East Asia. More women's events were gradually introduced as years progressed (although it was only towards the end of the century that the men's and women's programmes approached parity of events). Marking an increasingly inclusive approach to the sport, major track and field competitions for disabled athletes were first introduced at the 1960 Summer Paralympics.

With the rise of numerous regional championships, as well as the growth in Olympic-style multi-sport events (such as the Commonwealth Games and the Pan-American Games), competitions between international track and field athletes became widespread. From the 1960s onwards, the sport gained more exposure and commercial appeal through television coverage and the increasing wealth of nations. After over half a century of amateurism, the amateur status of the sport began to be displaced by growing professionalism in the late 1970s. As a result, the Amateur Athletic Union was dissolved in the United States and it was replaced with a non-amateur body solely focused on the sport of athletics: The Athletics Congress (later USA Track and Field). The IAAF abandoned amateurism in 1982 and later removed all references to it from its name by rebranding itself as the International Association of Athletics Federations. While Western countries were limited to amateurs until the early 1980s, Soviet Bloc countries always fielded state-funded athletes who trained full-time, putting American and Western European athletes at a significant disadvantage. 1983 saw the establishment of the IAAF World Championships in Athletics—the first-ever global competition just for athletics—which, with the Olympics, became one of track and field's most prestigious competitions.

The profile of the sport reached a new high in the 1980s, with a number of athletes becoming household names (such as Carl Lewis, Sergey Bubka, Sebastian Coe, Zola Budd and Florence Griffith Joyner). Many world records were broken in this period, and the added political element between competitors of the United States, East Germany, and the Soviet Union, in reaction to the Cold War, only served to stoke the sport's popularity. The increase in the commercial capacity of track and field was also met with developments in the application of sports science, and there were many changes to coaching methods, athlete's diet regimes, training facilities, and sports equipment. This was also accompanied by an increase in the use of performance-enhancing drugs. State-sponsored doping in 1970s and 1980s East Germany, China, the Soviet Union, and early 21st century Russia, as well as prominent individual cases such as those of Olympic gold medallists Ben Johnson and Marion Jones, damaged the public image and marketability of the sport.

From the 1990s onwards, track and field became increasingly more professional and international, as the IAAF gained over two hundred member nations. The IAAF World Championships in Athletics became a fully professional competition with the introduction of prize money in 1997, and in 1998 the IAAF Golden League—an annual series of major track and field meetings in Europe—provided a higher level of economic incentive in the form of a US$1 million jackpot. In 2010, the series was replaced by the more lucrative Diamond League, a fourteen-meeting series held in Europe, Asia, North America, and the Middle East—the first-ever worldwide annual series of track and field meetings.

Events

Track and field events are divided into three broad categories: track events, field events, and combined events. The majority of athletes tend to specialize in just one event (or event type) with the aim of perfecting their performances, although the aim of combined events athletes is to become proficient in a number of disciplines. Track events involve running on a track over specified distances, and—in the case of the hurdling and steeplechase events—obstacles may be placed on the track. There are also relay races in which teams of athletes run and pass on a baton to their team members at the end of a certain distance.

There are two types of field events: jumps and throws. In jumping competitions, athletes are judged on either the length or height of their jumps. The performances of jumping events for distance are measured from a board or marker, and any athlete overstepping this mark is judged to have fouled. In the jumps for height, an athlete must clear their body over a crossbar without knocking the bar off the supporting standards. The majority of jumping events are unaided, although athletes propel themselves vertically with purpose-built sticks in the pole vault.

The throwing events involve hurling an implement (such as a heavyweight, javelin, or discus) from a set point, with athletes being judged on the distance that the object is thrown. Combined events involve the same group of athletes contesting a number of different track and field events. Points are given for their performance in each event and the athlete and/or team with the greatest points total at the end of all events is the winner.

Track

Sprints

Races over short distances, or sprints, are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event, the stadion race, which was a race from one end of the stadium to the other. Sprinting events are focused on athletes reaching and sustaining their quickest possible running speed. Three sprinting events are currently held at the Olympics and outdoor World Championships: the 100 metres, 200 metres, and 400 metres. These events have their roots in races of imperial measurements that later changed to metric: the 100 m evolved from the 100-yard dash, the 200 m distances came from the furlong (or 1/8 of a mile), and the 400 m was the successor to the 440 yard dash or quarter-mile race.

At the professional level, sprinters begin the race by assuming a crouching position in the starting blocks before leaning forward and gradually moving into an upright position as the race progresses and momentum is gained.100 m – For the Expert

IAAF. Retrieved on 26 March 2010. with the sole exception of the 400 m indoors. Races up to 100 m are largely focused upon acceleration to an athlete's maximum speed. All sprints beyond this distance increasingly incorporate an element of endurance. Human physiology dictates that a runner's near-top speed cannot be maintained for more than thirty seconds or so because lactic acid builds up once leg muscles begin to suffer oxygen deprivation. Top speed can only be maintained for up to 20 metres.

The 60 metres is a common indoor event and indoor world championship event. Less-common events include the 50 metres, 55 metres, 300 metres, and 500 metres, which are run in some high school and collegiate competitions in the United States. The 150 metres, though rarely competed, has a star-studded history: Pietro Mennea set a world best in 1983,Superb Bolt storms to 150m record
BBC Sport (17 May 2009). Retrieved on 26 March 2010. Olympic champions Michael Johnson and Donovan Bailey went head-to-head over the distance in 1997, and Usain Bolt improved Mennea's record in 2009.

Middle distance

The most common middle-distance track events are the 800 metres, 1500 metres and mile run, although the 3000 metres may also be classified as a middle-distance event. The 880 yard run, or half mile, was the forebear of the 800 m distance and it has its roots in competitions in the United Kingdom in the 1830s. The 1500 m came about as a result of running three laps of a 500 m track, which was commonplace in continental Europe in the 20th century.

Runners start the race from a standing position along a curved starting line and after hearing the starting pistol they head towards the innermost track to follow the quickest route to the finish. In 800 m races athletes begin at a staggered starting point before the turn in the track and they must remain in their lanes for the first 100 m of the race. This rule was introduced to reduce the amount of physical jostling between runners in the early stages of the race. Physiologically, these middle-distance events demand that athletes have good aerobic and anaerobic energy producing systems, and also that they have strong endurance.

The 1500 m and mile run events have historically been some of the most prestigious track and field events. Swedish rivals Gunder Hägg and Arne Andersson broke each other's 1500 m and mile world records on a number of occasions in the 1940s. The prominence of the distances were maintained by Roger Bannister, who (in 1954) was the first to run the long-elusive four-minute mile, and Jim Ryun's exploits served to popularise interval training. Races between British rivals Sebastian Coe, Steve Ovett and Steve Cram characterised middle-distance running in the 1980s. From the 1990s onwards, North Africans such as Noureddine Morceli of Algeria and Hicham El Guerrouj of Morocco came to dominate the 1500 and mile events.

Beyond the short distances of sprinting events, factors such as an athlete's reactions and top speed becomes less important, while qualities such as pace, race tactics and endurance become more so.800 m – Introduction

Long-distance

There are three common long-distance running events in track and field competitions: 3000 metres, 5000 metres and 10,000 metres. The latter two races are both Olympic and World Championship events outdoors, while the 3000 m is held at the IAAF World Indoor Championships. The 5000 m and 10,000 m events have their historical roots in the 3-mile and 6-mile races. The 3000 m was historically used as a women's long-distance event, entering the World Championship programme in 1983 and Olympic programme in 1984, but this was abandoned in favour of a women's 5000 m event in 1995.5000-10000 m – Introduction
IAAF. Retrieved on 7 April 2010. Marathons, while long-distance races, are typically run on street courses, and often are run separately from other track and field events.

In terms of competition rules and physical demands, long-distance track races have much in common with middle-distance races, except that pacing, stamina, and race tactics become much greater factors in performances.Introduction to Long Distance Events
. About.com. Retrieved on 7 April 2010. However, a number of athletes have achieved success in both middle- and long-distance events, including Saïd Aouita who set world records from 1500 m to 5000 m. The use of pace-setters in long-distance events is very common at the elite level, although they are not present at championship level competitions as all qualified competitors want to win.

The long-distance track events gained popularity in the 1920s by the achievements of the " Flying Finns", such as multiple Olympic champion Paavo Nurmi. The successes of Emil Zátopek in the 1950s promoted intense interval training methods, but Ron Clarke's world record-breaking feats established the importance of natural training and even-paced running. The 1990s saw the rise of North and East African runners in long-distance events. Kenyan and Ethiopian athletes, in particular, have since remained dominant in these events.

Relay races

Relay races are the only track and field event in which a team of runners directly compete against other teams.4 × 100 m Relay – Is it for me?
IAAF. Retrieved on 9 April 2010. Typically, a team is made up of four runners of the same sex. Each runner completes their specified distance (referred to as a leg) before handing over a baton to a teammate, who then begins their leg upon receiving the baton. There is usually a designated area where athletes must exchange the baton. Teams may be disqualified if they fail to complete the change within the area, or if the baton is dropped during the race. A team may also be disqualified if its runners are deemed to have wilfully impeded other competitors.

Relay races emerged in the United States in the 1880s as a variation on charity races between firemen, who would hand a red pennant on to teammates every 300 yards. There are two very common relay events: the 4×100 metres relay and the 4×400 metres relay. Both events entered the Olympic programme at the 1912 Summer Games after a one-off men's medley relay featured in 1908 Olympics.4 × 100 m Relay – Introduction
IAAF. Retrieved on 9 April 2010. The 4 × 100 m event is run strictly within the same lane on the track, meaning that the team collectively runs one complete circuit of the track. Teams in a 4 × 400 m event remain in their own lane until the runner of the second leg passes the first bend, at which point runners can leave their lanes and head towards the inner-most part of the circuit. For the second and third baton change overs, teammates must align themselves in respect of their team position – leading teams take the inner lanes while teammates of the slower teams must await the baton on outer lanes.

The Shuttle Hurdle Relay per Hurdling web page: In a shuttle hurdle relay, each of four hurdlers on a team runs the opposite direction from the preceding runner. No batons are used for this particular relay.

The IAAF keeps world records for five different types of track relays. As with 4×100 m and 4×400 m events, all races comprise teams of four athletes running the same distances, with the less commonly contested distances being the 4×200 m, 4×800 m and 4×1500 m relays. Other events include the distance medley relay (comprising legs of 1200 m, 400 m, 800 m, and 1600 m), which is frequently held in the United States, and a sprint relay, known as the Swedish medley relay, which is popular in Scandinavia and was held at the IAAF World Youth Championships in Athletics programme. Relay events have significant participation in the United States, where a number of large meetings (or relay carnivals) are focused almost exclusively on relay events.

Hurdling

Races with hurdles as obstacles were first popularised in the 19th century in England. The first known event, held in 1830, was a variation of the 100-yard dash that included heavy wooden barriers as obstacles. A competition between the Oxford and Cambridge Athletic Clubs in 1864 refined this, holding a 120-yard race (110 m) with ten hurdles of 3-foot and 6 inches (1.06 m) in height (each placed 10 yards (9 m) apart), with the first and final hurdles 15 yards from the start and finish, respectively. French organisers adapted the race into metric (adding 28 cm) and the basics of this race, the men's 110 metres hurdles, has remained largely unchanged.100 m Hurdles – Introduction
IAAF. Retrieved on 9 April 2010. The origin of the 400 metres hurdles also lies in Oxford, where (around 1860) a competition was held over 440 yards and twelve 1.06 m high wooden barriers were placed along the course. The modern regulations stem from the 1900 Summer Olympics: the distance was fixed to 400 m while ten 3-foot (91.44 cm) hurdles were placed 35 m apart on the track, with the first and final hurdles being 45 m and 40 m away from the start and finish, respectively.400 m Hurdles – Introduction
IAAF. Retrieved on 9 April 2010. Women's hurdles are slightly lower at 84 cm (2 ft 9 in) for the 100 m event and 76 cm (2 ft 6 in) for the 400 m event.

By far the most common events are the 100 metres hurdles for women, 110 m hurdles for men and 400 m hurdles for both sexes. The men's 110 m has been featured at every modern Summer Olympics while the men's 400 m was introduced in the second edition of the Games. Women's initially competed in the 80 metres hurdles event, which entered the Olympic programme in 1932. This was extended to the 100 m hurdles at the 1972 Olympics, but it was not until 1984 that a women's 400 m hurdles event took place at the Olympics (having been introduced at the 1983 World Championships in Athletics the previous year). Other distances and heights of hurdles, such as the 200 metres hurdles and low hurdles, were once common but are now held infrequently. The 300 metres hurdles is run in some levels of American competition.

Outside of the hurdles events, the steeplechase race is the other track and field event with obstacles. Just as the hurdling events, the steeplechase finds its origin in student competition in Oxford, England. However, this event was born as a human variation on the original steeplechase competition found in horse racing. A steeplechase event was held on a track for the 1879 English championships and the 1900 Summer Olympics featured men's 2500 m and 4000 m steeplechase races. The event was held over various distances until the 1920 Summer Olympics marked the rise of the 3000 metres steeplechase as the standard event.3000 m Steeplechase – Introduction
IAAF. Retrieved on 9 April 2010. The IAAF set the standards of the event in 1954, and the event is held on a 400 m circuit that includes a water jump on each lap. Despite the long history of men's steeplechase in track and field, the women's steeplechase only gained World Championship status in 2005, with its first Olympic appearance in 2008.

Field

Jumping

Long jump

The long jump is one of the oldest track and field events, having its roots as one of the events within the ancient Greek pentathlon contest. The athletes would take a short run up and jump into an area of dug up earth, with the winner being the one who jumped farthest. Small weights ( Halteres) were held in each hand during the jump then swung back and dropped near the end to gain extra momentum and distance.Miller, Steven G. (2004). ''Ancient Greek Athletics''. Pg. 68. Yale University. . The modern long jump, standardised in England and the United States around 1860, bears resemblance to the ancient event although no weights are used. Athletes sprint along a length of track that leads to a jumping board and a sandpit.Long Jump – Introduction
IAAF. Retrieved on 10 May 2010. The athletes must jump before a marked line and their achieved distance is measured from the nearest point of sand disturbed by the athlete's body.Rosenbaum, Mike
Introduction to the Long Jump
. About. Retrieved on 10 May 2010.

The athletics competition at the first Olympics featured a men's long jump competition and a women's competition was introduced at the 1948 Summer Olympics. Professional long jumpers typically have strong acceleration and sprinting abilities. However, athletes must also have a consistent stride to allow them to take off near the board while still maintaining their maximum speed. In addition to the traditional long jump, a standing long jump contest exists which requires that athletes leap from a static position without a run-up. A men's version of this event featured on the Olympic programme from 1900 to 1912.

Triple jump

Similar to the long jump, the triple jump takes place on a track heading towards a sandpit. Originally, athletes would hop on the same leg twice before jumping into the pit, but this was changed to the current "hop, step and jump" pattern from 1900 onwards.Triple Jump – Introduction
IAAF. Retrieved on 10 May 2010. There is some dispute over whether the triple jump was contested in ancient Greece: while some historians claim that a contest of three jumps occurred at Ancient Games, others such as Stephen G. Miller believe this is incorrect, suggesting that the belief stems from a mythologised account of Phayllus of Croton having jumped 55 ancient feet (around 16.3 m). The Book of Leinster, a 12th-century Irish manuscript, records the existence of ''geal-ruith'' (triple jump) contests at the Tailteann Games.

The men's triple jump competition has been ever-present at the modern Olympics, but it was not until 1993 that a women's version gained World Championship status and went on to have its first Olympic appearance three years later. The men's standing triple jump event featured at the Olympics in 1900 and 1904, but such competitions have since become very uncommon, although it is still used as a non-competitive exercise drill. The Current world record for the Men's triple jump is 18.29 meter (60 ft 0in) held by Jonathan Edwards. The current women's world record is 15.67 meters (51 ft 4 3/4in) held by Yulimar Rojas.

High jump

The first recorded instances of high jumping competitions were in Scotland in the 19th century. Further competitions were organised in 1840 in England and in 1865 the basic rules of the modern event were standardised there.High Jump - Introduction
IAAF. Retrieved on 10 May 2010. Athletes have a short run up and then take off from one foot to jump over a horizontal bar and fall back onto a cushioned landing area. The men's high jump was included in the 1896 Olympics and a women's competition followed in 1928.

Jumping technique has played a significant part in the history of the event. High jumpers typically cleared the bar feet first in the late 19th century, using either the Scissors, Eastern cut-off or Western roll technique. The straddle technique became prominent in the mid-20th century, but Dick Fosbury overturned tradition by pioneering a backwards and head-first technique in the late 1960s – the Fosbury Flop – which won him the gold at the 1968 Olympics. This technique has become the overwhelming standard for the sport from the 1980s onwards. The standing high jump was contested at the Olympics from 1900 to 1912, but is now relatively uncommon outside of its use as an exercise drill.

Pole vault

In terms of sport, the use of poles for vaulting distances was recorded in Fierljeppen contests in the Frisian area of Europe, and vaulting for height was seen at gymnastics competitions in Germany in the 1770s.Pole Vault – Introduction
IAAF. Retrieved on 10 May 2010. One of the earliest recorded pole vault competitions was in Cumbria, England in 1843. The basic rules and technique of the event originated in the United States. The rules required that athletes do not move their hands along the pole and athletes began clearing the bar with their feet first and twisting so that the stomach faces the bar. Bamboo poles were introduced in the 20th century and a metal box in the runway for planting the pole became standard. Landing mattresses were introduced in the mid-20th century to protect the athletes who were clearing increasingly greater heights.

The modern event sees athletes run down a strip of track, plant the pole in the metal box, and vault over the horizontal bar before letting go of the pole and falling backwards onto the landing mattress. While earlier versions used wooden, metal or bamboo, modern poles are generally made from artificial materials such as fibreglass or carbon fibre. The pole vault has been an Olympic event since 1896 for men, but it was over 100 years later that the first women's world championship competition was held at the 1997 IAAF World Indoor Championships. The first women's Olympic pole vaulting competition occurred in 2000.

Throwing

Track and field contains some of the foremost kinds of throwing sports, and the four major disciplines are the only pure throwing events to feature at the Olympic Games.

Shot put

The genesis of the shot put can be traced to pre-historic competitions with rocks: in the Middle ages the stone put was known in Scotland and the steinstossen was recorded in Switzerland. In the 17th century, cannonball throwing competitions within the English military provided a precursor to the modern sport.Shot Put - Introduction
IAAF. Retrieved on 11 May 2010. The term "shot" originates from the use of round shot-style ammunition for the sport. The modern rules were first laid out in 1860 and required that competitors take legal throws within a square throwing area of seven feet (2.13 m) on each side. This was amended to a circle area with a seven-foot diameter in 1906, and the weight of the shot was standardised to 16 pounds (7.26 kg). Throwing technique was also refined over this period, with bent arm throws being banned as they were deemed too dangerous and the side-step and throw technique arising in the United States in 1876.

The shot put has been an Olympic sport for men since 1896 and a women's competition using a 4 kg (8.82 lb) shot was added in 1948. Further throwing techniques have arisen since the post-war era: in the 1950s Parry O'Brien popularised the 180 degree turn and throw technique commonly known as the "glide", breaking the world record 17 times along the way, while Aleksandr Baryshnikov and Brian Oldfield introduced the "spin" or rotational technique in 1976.

Discus throw

In the discus throw, athletes compete to throw a heavy disc the farthest. In standard competitions, athletes throw the disc from a set circular arc and take turns in a series of throw, with the singular best effort deciding the victor. As one of the events within the ancient pentathlon, the history of the discus throw dates back to 708 BC.Miller, Steven G. (2004). ''Ancient Greek Athletics''. Pg. 61. Yale University. . In ancient times a heavy circular disc was thrown from a set standing position on a small pedestal, and it was this style that was revived for the 1896 Olympics.Discus Throw – Introduction
IAAF. Retrieved on 11 May 2010. This continued until the 1906 Intercalated Games in Athens, which featured both the ancient style and the increasingly popular modern style of turning and throwing. By the 1912 Olympics, the ancient standing throw style had fallen into disuse and contests starting within a 2.5 m squared throwing area became the standard. The discus implement was standardised to 2 kg (4.4 pounds) in weight and 22 cm (8 inches) in diameter in 1907. The women's discus was among the first women's events on the Olympic programme, being introduced in 1928. The first modern athlete to throw the discus while rotating the whole body was Czech athlete František Janda-Suk, who invented the technique when studying the position of the famous statue of Discobolus and won the 1900 Olympic silver medal.

Javelin throw

As an implement of war and hunting, javelin throwing began in prehistoric times.Rosenbaum, Mike
An Illustrated History of Javelin – The early days of Javelin throwing
About. Retrieved on 11 May 2010. Along with the discus, the javelin was the second throwing event in the ancient Olympic pentathlon. Records from 708 BC show two javelin competition types co-existing: throwing at a target and throwing the javelin for distance. It was the latter type from which the modern event derives.
IAAF. Retrieved on 11 May 2010. In ancient competitions, athletes would wrap an ''ankyle'' (thin leather strip) around the javelin that acted as a sling to facilitate extra distance.Miller, Steven G. (2004). ''Ancient Greek Athletics''. Pg. 69. Yale University. . The javelin throw gained much popularity in Scandinavia in the late 19th century and athletes from the region are still among the most dominant throwers in men's competitions. The modern event features a short run up on a track and then the thrower releases the javelin before the foul line. The runway measures at a minimum of 30m in length, and is covered with the same surface as the track.

The first Olympic men's javelin throw contest was held in 1908 and a women's competition was introduced in 1932. The first javelins were made of various types of wood, but in the 1950s, former athlete Bud Held introduced a hollow javelin, then a metal javelin, both of which increased throwers performances. Another former athlete, Miklós Németh invented the rough-tailed javelin and throws reached in excess of 100 m – edging towards the limits of stadia. The distances and the increasing number of horizontal landings led the IAAF to redesign the men's javelin to reduce distance and increase the implement's downward pitching moment to allow for easier measurement. Rough-tailed designs were banned in 1991 and all marks achieved with such javelins were removed from the record books. The women's javelin underwent a similar redesign in 1999. The current javelin specifications are 2.6 to 2.7 m in length and 800 grams in weight for men, and 2.2 to 2.3 m and 600 g for women.

Hammer throw

The earliest recorded precursors to the modern hammer throw stem from the Tailteann Games of ancient Ireland, which featured events such as throwing either a weight attached to a rope, a large rock on a wooden handle, or even a chariot wheel on a wooden axle.Rosenbaum, Mike
An Illustrated History of the Hammer Throw – The early days of the hammer throw
About. Retrieved on 11 May 2010. Other ancient competitions included throwing a cast iron ball attached to a wooden handle – the root of the term "hammer throw" due to their resemblance to the tools.
IAAF. Retrieved on 11 May 2010. In 16th century England, contests involving the throwing of actual blacksmith's Sledgehammers were recorded. The hammer implement was standardised in 1887 and the competitions began to resemble the modern event. The weight of the metal ball was set at 16 pounds (7.26 kg) while the attached wire had to measure between 1.175 m and 1.215 m.

The men's hammer throw became an Olympic event in 1900 but the women's event – using a 4 kg (8.82 lb) weight – was not widely competed until much later, finally featuring on the women's Olympic programme in 2000. The distances thrown by male athletes became greater from the 1950s onwards as a result of improved equipment using the denser metals, a switch to concrete throwing areas, and more advanced training techniques. Professional hammer throwers were historically large, strong, sturdy athletes. However, qualities such as refined technique, speed and flexibility have become increasingly important in the modern era as the legal throwing area has been reduced from 90 to 34.92 degrees and throwing technique involves three to four controlled rotations.

Combined events

Combined (or multi-discipline) events are competitions in which athletes participate in a number of track and field events, earning points for their performance in each event, which adds to a total points score. Outdoors, the most common combined events are the men's decathlon (ten events) and the women's heptathlon (seven events). Due to stadium limitations, indoor combined events competition have a reduced number of events, resulting in the men's heptathlon and the women's pentathlon. Athletes are allocated points based on an international-standard points scoring system, such as the decathlon scoring table.

The Ancient Olympic pentathlon (comprising long jump, javelin, discus, the '' stadion'' race and wrestling) was a precursor to the track and field combined events and this ancient event was restored at the 1906 Summer Olympics ( Intercalated Games). A men's all-around was held at the 1904 Summer Olympics, contested between five American and two British athletes.

Stadiums

Outdoor

The term ''track and field'' is intertwined with the stadiums that first hosted such competitions. The two basic features of a track and field stadium are the outer oval-shaped running track and an area of turf within this track—the field. In earlier competitions, track lengths varied: the Panathinaiko Stadium measured 333.33 metres at the 1896 Summer Olympics, while at the 1904 Olympics the distance was a third of a mile (536.45 m) at Francis Field. As the sport developed, the IAAF standardised the length to 400 m and stated that the tracks must be split into six to eight running lanes. Precise widths for the lanes were established, as were regulations regarding the curvature of the track. Tracks made of flattened cinders were popular in the early 20th century but synthetic tracks became standard in the late 1960s. 3M's Tartan track (an all-weather running track of polyurethane) gained popularity after its use at the 1968 US Olympic Trials and the 1968 Summer Olympics and it began the process in which synthetic tracks became the standard for the sport. Many track and field stadiums are multi-purpose stadiums, with the running track surrounding a field built for other sports, such as the various types of football.

The field of the stadium combines a number of elements for use in the jumping and throwing events. The long jump and triple jump areas comprise a straight, narrow 40-metre running track with a sandpit at one or both ends. Jumps are measured from a take off board—typically a small strip of wood with a plasticine marker attached—which ensures athletes jump from behind the measurement line. The pole vault area is also a 40-metre running track and has an indentation in the ground (the box) where vaulters plant their poles to propel themselves over a crossbar before falling onto cushioned landing mats. The high jump is a stripped-down version of this, with an open area of track or field that leads to a crossbar with a square area of landing mats behind it.

The four throwing events generally all begin on one side of the stadium. The javelin throw typically takes place on a piece of track that is central and parallel to the straights of the main running track. The javelin throwing area is a sector shape frequently across the Pitch (sports field) in the middle of the stadium, ensuring that the javelin has a minimal chance of causing damage or injury. The discus throw and hammer throw contests begin in a tall metal cage usually situated in one of the corners of the field. The cage reduces the danger of implements being thrown out of the field of play and throws travel diagonally across the field in the centre of the stadium. The shot put features a circular throwing area with a toe board at one end. The throwing area is a sector. Some stadia also have a water jump area on one side of the field specifically for steeplechase races.

Indoor

Basic indoor venues may be adapted gymnasiums, which can easily accommodate high jump competitions and short track events. Full-size indoor arenas (i.e. those fully equipped to host all events for the World Indoor Championships) bear similarities with their outdoor equivalents. Typically, a central area is surrounded by a 200-metre oval track with four to eight lanes. The track can be banked at the turns to allow athletes to run around the radius more comfortably. Some have a second running track going straight across the field area, parallel to the straights of the main circuit. This track is used for the 60 metres and 60 metres hurdles events, which are held almost exclusively indoors.

Another common adaptation in the United States is a 160-yard track (11 laps to a mile) that fits into a common basketball court-sized arena. This was quite popular when races were held at imperial distances, which gradually was phased out by different organizations in the 1970s and 1980s. Examples of this configuration include the Millrose Games at Madison Square Garden, and the Sunkist Invitational formerly held in the Los Angeles Sports Arena.

All four of the common jumping events are held at indoor venues. The long and triple jump areas run alongside the central 60 m track and are mostly identical in form to their outdoor counterparts. The pole vault track and landing area are also alongside the central running track. Shot put and weight throw are the only throwing events held indoors due to size restrictions. The throwing area is similar to the outdoor event, but the landing sector is a rectangular section surrounded by netting or a stop barrier.

In addition to hosting the World Indoor Championships, the IAAF has hosted the IAAF World Indoor Tour since 2016.

Starts use in race

Track rules

The rules of track events in athletics as observed in most international athletics competitions are set by the Competition Rules of the International Association of Athletics Federations (IAAF). The most recent complete set of rules is the 2009 rules that relate only to competitions in 2009.Incorporating changes approved by the IAAF Council throughout 2008- p5, 2009 Rule book
Key rules of track events are those regarding starting, running and finishing. Current World Athletics (WA) Rules are available on WA's websit

Current USATF (USA) Competition Rules booklet is available on the USATF websit

Prior USATF Competition Rules booklets are also available (2002, 2006 to 2020

Starting

The start of a race is marked by a white line 5 cm wide. In all races that are not run in lanes the start line must be curved, so that all the athletes start the same distance from the finish.
Starting blocks may be used for all races up to and including 400 m (including the first leg of the 4 × 100 m relay, 4 × 100 m and 4 × 400 m) and may not be used for any other race. No part of the starting block may overlap the start line or extend into another lane.

All races must be started by the report of the starter's gun or approved starting apparatus fired upwards after they have ascertained that athletes are steady and in the correct starting position.IAAF Rule 161.2 An athlete may not touch either the start line or the ground in front of it with their hands or feet when on their marks.IAAF Rule 161.3

For sprint races up to 400 m, the starter gives two commands: "on your marks" to instruct athletes to approach the start line, followed by "set" to advise the athletes that the start of the race is imminent. The commands of the starter are typically given in the native language in national competitions, or in English or French in international competitions. Once all athletes are set in their starting position, the gun or an approved starting apparatus must be fired or activated. If the starter is not satisfied that all are ready to proceed, the athletes may be called out of the blocks and the process started over.

There are different types of starts for races of different distances. Middle- and long-distance races mainly use the waterfall start. This is when all athletes begin on a curved line that moves farther out at the outer edge of the track. Competitors are allowed to move towards the inside lane right away, as long as it is safe to do so. For some middle-distance races, such as 800 m, each athlete starts in their own lane. Once the gun fires, they must run in the lane they began in until markers on the track notify them it is time to move towards the inside lane. For sprint races, athletes begin in start blocks and must stay in their own lane for the entire race.

An athlete, after assuming a final set position, may not commence his starting motion until after receiving the report of the gun, or approved starting apparatus. If, in the judgment of the starter or recallers, he does so any earlier, it is considered a false start. It is deemed a false start if, in the judgment of the starter an athlete fails to comply with the commands "on your marks" or "set" as appropriate after a reasonable time; or an athlete after the command "on your marks" disturbs other athletes in the race through sound or otherwise. If the runner is in the "set" position and moves, then the runner is also disqualified. , any athlete making a false start is disqualified.

In International elite competition, electronically tethered starting blocks sense the reaction time of the athletes. If the athlete reacts in less than 0.1 second, an alert sounds for a recall starter and the offending athlete is guilty of a false start. Since 2009, the offending athletes are immediately disqualified.

Running the race

For sprinting events (bar the 4 × 400 m relay and the indoor 400 metres), each athlete must run the race within their allocated lane from start to finish. If an athlete leaves their lane or steps on the line demarking each lane the athlete will be disqualified. Lane rules also apply for initial periods of other track races, for example, the beginning of the 800 m. Similar rules apply for longer distance races when a large field of athletes is present and separate starting points are designated, with the field merging into one group shortly after the starting phase.IAAF Rule 163.2IAAF Rule 163.3

Any athlete who jostles or obstructs another athlete, in a way that impedes his progress, should be disqualified from that event. However, if an athlete is pushed or forced by another person to run outside his lane, and if no material advantage is gained, the athlete should not be disqualified.

The finish

The finish of a race is marked by a white line 5 cm wide. The finishing position of athletes is determined by the order in which any part of their torso (as distinguished from the head, neck, arms, legs, hands or feet) reaches the vertical plane of the nearer edge of the finish line. Fully automatic timing systems (photo timing) are becoming more and more common at increasingly lower levels of track meets, improving the accuracy, while eliminating the need for eagle-eyed officials on the finish line. Fully automatic timing (FAT) is required for high level meets and any time a sprint record is set (though distance records can be accepted if timed by three independent stopwatches).

With the accuracy of the timing systems, ties are rare. Ties between different athletes are resolved as follows: In determining whether there has been a tie in any round for a qualifying position for the next round based on time, a judge (called the chief photo finish judge) must consider the actual time recorded by the athletes to one thousandth of a second. If the judge decides that there has been a tie, the tying athletes must be placed in the next round or, if that is not practicable, lots must be drawn to determine who must be placed in the next round. In the case of a tie for first place in any final, the referee decides whether it is practicable to arrange for the athletes so tying to compete again. If he decides it is not, the result stands. Ties in other placings remain.

Field rules

In general, most field events allow a competitor to take their attempt individually, under theoretically the same conditions as the other competitors in the competition. Each attempt is measured to determine who achieved the greatest distance.

Vertical Jumps

Vertical jumps (high jump and pole vault) set a bar at a particular height. The competitor must clear the bar without knocking it off the standards that are holding the bar (flat). Three failures in a row ends the competitor's participation in the event. The competitor has the option to PASS their attempt, which can be used to strategic advantage (of course that advantage is lost if the competitor misses). A pass could be used to save energy and avoid taking a jump that would not improve their position in the standings. After all competitors have either cleared, passed or failed their attempts at a height, the bar goes up. The amount the bar goes up is predetermined before the competition, though when one competitor remains, that competitor may choose their own heights for the remaining attempts. A record is kept of each attempt by each competitor. After all competitors have taken their attempts, the one jumping the highest is the winner, and so on down the other competitors in the event. Ties are broken by first, the number of attempts taken at the highest height (fewest wins), and then if still tied, by the total number of misses in the competition as a whole. The bar does not go back to a lower height except to break a tie for first place or a qualifying position. If those critical positions are still tied after applying the tiebreakers, all tied competitors take a fourth jump at the last height. If they still miss, the bar goes down one increment where they again jump. This process continues until the tie is broken.

Horizontal Jumps

Horizontal jumps (long jump and triple jump) and all throws must be initiated behind a line. In the case of horizontal jumps, that line is a straight line perpendicular to the runway. In the case of throws, that line is an arc or a circle. Crossing the line while initiating the attempt invalidates the attempt—it becomes a foul. All landings must occur in a sector. For the jumps, that is a sand filled pit, for throws it is a defined sector. A throw landing on the line on the edge of sector is a foul (the inside edge of the line is the outside edge of the sector). Assuming a proper attempt, officials measure the distance from the closest landing point back to the line. The measuring tape is carefully straightened to the shortest distance between the point and the line. To accomplish this, the tape must be perfectly perpendicular to the take off line in jumps, or is pulled through the center point of the arc for throws. The officials at the landing end of the tape have the zero, while the officials at the point of initiation measure and record the length. Whenever a record (or potential record) occurs, that measurement is taken (again) with a steel tape, and observed by at least three officials (plus usually the meet referee). Steel tapes are easily bent and damaged, so are not used to measure everyday competitions. For major competitions, each competitor gets three tries. The top competitors (usually 8 or 9 depending on that competition's rules or the number of lanes on the track) gets three more tries. At that level of competition, the order of competitors for those final three attempts are set—so the competitor in first place at the end of the third round is last, while the last competitor to qualify goes first. Some meets rearrange the competition order again for the final round, so the final attempt is taken by the leader at that point. At other competitions, meet management may choose to limit all competitors to four or three attempts. Whatever the format, all competitors get an equal number of attempts.

Equipment

Men and women have different weights for their throwing implements – men's javelin is 800 grams compared to 600 for women, men's weight throw is 35 pounds compared to 20 for women, men's discus is 2 kilograms to women's 1, men's shot put is 16 pounds compared to 8 pounds for women, and men's hammer throw is also 16 pounds to the women's 8. Additionally, men's high hurdles are at height of 42 inches compared to women's hurdles which are 33 inches. For the intermediate hurdles (400 meter hurdles), the men's hurdle height is 36 inches compared to 30 inches for women.

Organizations

The international governance of track and field falls under the jurisdiction of athletics organisations. World Athletics is the global governing body for track and field, and athletics as a whole. The governance of track and field at continental and national level is also done by athletics bodies. Some national federations are named after the sport, including USA Track & Field and the Philippine Amateur Track & Field Association, but these organisations govern more than just track and field and are in fact athletics governing bodies. These national federations regulate sub-national and local track and field clubs, as well as other types of running clubs.IAAF Member Federation Manual – Chapter 2

Competitions

Olympics, Paralympics and world championships

The major global track and field competitions are both held under the scope of athletics. Track and field contests make up the majority of events on the Olympic and Paralympic athletics programmes, which occur every four years. Track and field events have held a prominent position at the Summer Olympics since its inception in 1896, and the events are typically held in the main stadium of the Olympic and Paralympic Games. Events such as the 100 metres receive some of the highest levels of media coverage of any Olympic or Paralympic sporting event.

The other two major international competition for track and field are organised by the IAAF. The IAAF had selected the Olympic competition as its world championship event in 1913, but a separate world championships for athletics alone was first held in 1983 – the IAAF World Championships in Athletics. The championships comprised track and field competitions plus the marathon and racewalking competitions. Initially, this worked on a quadrennial basis but, after 1991, it changed to a biennial format. In terms of indoor track and field, the IAAF World Indoor Championships has been held every two years since 1985 and this is the only world championships that consists of solely track and field events.

Other championships

Similar to the event programmes at the Olympics, Paralympics and World Championships, track and field forms a significant part of continental championships. The South American Championships in Athletics, created in 1919, was the first continental championships and the European Athletics Championships became the second championships of this type in 1934. The Asian Athletics Championships and African Championships in Athletics were created in the 1970s and Oceania started its championships in 1990.

There are also indoor continental competitions in Europe ( European Athletics Indoor Championships) and Asia (Asian Indoor Athletics Championships
