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. [1]

Contents

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 upright position as the race progresses and momentum is gained. The set position differs depending on the start. The use of starting blocks allows the sprinter to perform an enhanced isometric preload; this generates muscular pre-tension which is channelled into the subsequent forward drive, making it more powerful. Body alignment is of key importance in producing the optimal amount of force. Ideally the athlete should begin in a 4-point stance and drive forwards, pushing off using both legs for maximum force production. [2] Athletes remain in the same lane on the running track throughout all sprinting events, [1] with the sole exception of the 400 metre indoors. Races up to 100 metre are largely focused upon acceleration to an athlete's maximum speed. [2] All sprints beyond this distance increasingly incorporate an element of endurance. [3]

History

The stadion of ancient Nemea, Greece.

The first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, which was a sprinting race from one end of the stadium to the other. [4] The Diaulos (Δίαυλος, "double pipe") was a double-stadion race, c.400 metres (1,300 feet), introduced in the 14th Olympiad of the ancient Olympic Games (724 BC).

Sprint races were part of the original Olympic games in the 7th century B.C. as well as the first modern Olympic games which started in the late 19th century (Athens 1896) [5] featured the 100 meter and 400 meter. Athletes started both races from a crouched start (4 point stance). In both the original Olympics and the modern Olympics, only men were allowed to participate in track and field until the 1928 games in Amsterdam, Netherlands. [6] The 1928 games were the also the first games to use a 400 meter track, which became the standard for track and field.

The modern sprinting events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100-yard dash, [7] the 200 m distance came from the furlong (or 18 mile), [8] and the 400 m was the successor to the 440-yard dash or quarter-mile race. [1]

Technological advances have always improved sprint performances( i.e. starting blocks, synthetic track material, and shoe technology). In 1924, athletes used a small shovel to dig holes to start the race from. The world record in the 100 meter dash in 1924 was 10.4 seconds, while in 1948, (the first use of starting blocks) was 10.2 seconds, and was 10.1 seconds in 1956. The constant drive for faster athletes with better technology has brought man from 10.4 seconds to 9.58 seconds in less than 100 years.

Track events were measured with the metric system except for the United Kingdom and the United States until 1965 and 1974 respectively. The Amateur Athletic Association (AAU) [9] decided to switch track and field in the U.S. to the metric system to finally make track and field internationally equivalent. Before this, American athletes could only qualify for world records at international events and Olympic games.  

Biological factors for runners

Biological factors that determine a sprinter's potential include:

Common contemporary distances

60 meters [11]

  • Normally run indoors, on a straight section of an indoor athletic track.
  • Some of the fastest humans reach their maximum speed around the 60-metre mark.
  • 60-meters is often used as an outdoor distance by younger athletes when starting sprint racing.

Note: Indoor distances are less standardized as many facilities run shorter or occasionally longer distances depending on available space. 60m is the championship distance

100 meters [12]

  • Takes place on the straight of a standard outdoor 400 m track.
  • Often, the world-record holder in this race is considered "the world's fastest man/woman."
  • Primarily an outdoor race.

200 meters [13]

  • Begins on the curve of a standard track (where the runners are staggered in their starting position, to ensure that they all run the same distance), and ends on the home straight.
  • Competed both indoors and outdoors, with only slightly slower times than outdoors.

400 meters [14]

  • Runners are staggered in their starting positions to ensure that everyone runs the same distance.
  • Competed both indoors and outdoors, with only slightly slower times than outdoors.

4x400 meter relay [16]

  • Runners are staggered in their starting positions to ensure that everyone runs the same distance.
  • Runners use exchange zones to pass a baton.
  • Typically the final race at track meets.

Historical and uncommon distances

50 yards (45.72 m)

50 m

The 50 metres is an uncommon event and alternative to the 60 metres. Donovan Bailey holds the men's world record with a time of 5.56 seconds and Irina Privalova holds the women's world record with a time of 5.96 seconds.

60 yards (54.864 m)

  • A rarely run sprinting event that was once more commonplace. The world record time of 5.99 is held by Lee McRae, and was set in 1987. The time is often used for American Football speed training.

55 m

The 55 metres is an uncommon event that resulted from the metrication of the 60 yards, and is an alternative to the 60 metres.

70 Yards

  • An extremely rare sprinting event, that was occasionally run in the 1960s. The world record of 6.90 is held by Bob Hayes.

100 yards (91.44 m)

  • The outdoor standard in the English (imperial measured) speaking world. It was part of the Commonwealth Games up until 1966 and was the premier event in American high school sprinting until the NFHS changed to metric in 1980, now only a secondary distance to the 100 metres.
  • The unofficial World Record Holder is Jamaican Asafa Powell with a time of 9.07 seconds.

150 m

  • The informal distance of 150 metres (164.042 yards) can be used to work on a 100 m runner's stamina, or a 200 m runner's speed, and has been used as an exhibition distance. The distance was used in a race between 1996 Olympic champions, the 100 m gold medalist Donovan Bailey (Canada) and 200 m gold medalist Michael Johnson (USA). It was to decide which of the two was really the 'fastest man on earth' (see Bailey–Johnson 150-metre race).
  • The informal distance was used for an exhibition race during the Manchester Great CityGames in as part of the 2009 Great Manchester Run (UK). Stars included Triple Olympic Champion Usain Bolt (Jamaica) alongside Ivory Williams (USA), Simeon Williamson (UK) and other international track stars. The female race included 400 m Olympic Champion, Christine Ohuruogu of Great Britain alongside Debbie Ferguson-McKenzie (Bahamas). Bolt ran the distance in a record time of 14.35 seconds. [18] [19]

Stadion

The stadion, also known as the stade, was the standard short distance sprint in ancient Greece and ran the length of a stadium. However, stadiums could vary in size and there was apparently no definite standard length for them e.g. the stadium at Delphi measures 177 m and the one at Pergamon 210 m. [20]

300 m

  • The 300 metres is another informal distance, which could be used to aid a 200m runner's stamina, or a 400m runner's speed. Currently the world's best for this event is 30.81 seconds, set by Wayde van Niekerk in Ostrava, Czech Republic in 2017. [21] The women's record is 35.30 seconds, set by Ana Guevara at altitude in Mexico City in 2003. Junior girls in several countries run this distance instead of the 400 metres.

Diaulos

The diaulos was an event contested in the Ancient Greek Olympia that was double the length of a stadion.

4x200 meter relay [15]

  • Runners are staggered in their starting positions to ensure that everyone runs the same distance.
  • Runners use acceleration zones and exchange zones to pass a baton

Equipment

Shoes

Typically, a sprinter would only need 2 types of shoes, training shoes and sprinting spikes. [22]

Sprinting spikes are typically designed to be lightweight with minimal cushion on the heels and a plate on the forefoot to keep the runner on the toes of each foot. The spike plate will typically have the maximum number of holes for metal spikes be inserted in order to keep a proper grip on the track surface. These metal removable spikes also come in varying sizes. The spikes typically range from 4mm to 15mm, and come in different styles. Most facilities have specific requirements for what size and style spikes can be used. [23]

Starting Blocks [24]

Starting blocks are not a necessity, but are highly suggested for use in sprinting events. Starting blocks are a piece of equipment that typically consists of foot pads attached to a central rail. The point of using blocks is to help the athlete push themselves further down the track as quickly as possible.

Typical Block Start Set-up [25]

  • Place heel on slightly on the starting line
  • Place the blocks in the center of the track approximately where your toe is.
  • The dominant foot will be in the front block. With the paddle being set at 45 degrees
  • The front block will be about 1 ¾-2 foot lengths from the starting line.
  • The non-dominant foot will be in the back block.  The paddle will be set as high as possible.
  • The back block will be set about 3-3 ½ foot lengths from the starting line.
  • It is important to note that the front block and back block are only about 1 foot length apart.
  • The toes should barely touch the ground.  
  • Hands will be placed about shoulder width apart with the thumb and pointer finger slightly behind the line.
  • Arms should be in a straight position (locked or prepared to be locked at the elbows)
  • The arms will remain straight (if not locked at the elbows)
  • The hips will raise slightly above the shoulders (forcing the front half of the body to lean forward at about 45 degrees (slightly less).
  • A forward lean is optimal because it shifts most of the weight to the hands with minimal bend to the back.
  • The dominant leg should have about a 90 degree bend at the knee, while the non-dominant leg should be about 120 degrees
  • The arm on the dominant foot side will swing forward in an “exaggerated” fashion while the arm on the non-dominant side will swing backwards in the same fashion
  • The non-dominant foot will be the first step.
  • The non-dominant leg should come out with a long (within comfort’s range) stride, bringing the knee to a 90 degree position (separation of the foot and opposite leg’s knee about 2-2 ½ feet), approximately a 45 degree shin angle, and dorsiflexion with each stride.
  • Halfway before the first step lands, the “driving” position should have a straight line through the non-dominant ankle, knee, hips, shoulders, and head.

Baton

The baton is a required element for any relay race. The baton is passed to each athlete through different exchange zones, with different techniques. Typically about 1 foot long and 1.5 inches in diameter.

Timing

Stopwatches

Used typically in training sessions to measure relative times and recovery times. Stopwatches are not always the most accurate way to measure times in a race setting,

Fully Automatic Timing / Gate Systems

Fully Automatic Timing (FAT) and gate systems are used to accurately measure races with results as accurate up to 1/1000th of a second. [26]  

Governing Bodies

As of 2021, World Athletics (WA) [27] is the governing body for track and field around the world. Every country that wishes to participate in WA competitions must become a member. [28]

Rules

Rule differences with each Governing Bodies

Each governing body sets its own rules for how competition is deemed fair.  World Athletics sets the rules for competition internationally.  The World Athletics rulebook [29] is broken into 4 separate books.

The start

Starting blocks are used for all competition sprint (up to and including 400 m) and relay events (first leg only, up to 4x400 m). [30] The starting blocks consist of two adjustable footplates attached to a rigid frame. Races commence with the firing of the starter's gun. [30] The starting commands are "On your marks" and "Set". [30] Once all athletes are in the set position, the starter's gun is fired, officially starting the race. For the 100 m, all competitors are lined up side by side. For the 200 m, 300 m and 400 m, which involve curves, runners are staggered for the start.

In the rare event that there are technical issues with a start, a green card is shown to all the athletes. The green card carries no penalty. If an athlete is unhappy with track conditions after the "on your marks" command is given, the athlete must raise a hand before the "set" command and provide the Start referee with a reason. It is then up to the Start referee to decide if the reason is valid. In the event that the Start referee deems the reason invalid, a yellow card (warning) is issued to that particular athlete. In the event that the athlete is already on a warning the athlete is disqualified.

False starts

According to the World Athletics (WA) rules, "An athlete, after assuming a full and final set position, shall not commence his starting motion until after receiving the report of the gun, or approved starting apparatus. If, in the judgement of the Starter or Recallers, he does so any earlier, it shall be deemed a false start." [30]

The 100 m Olympic gold and silver medallist Linford Christie of Great Britain famously had frequent false starts that were marginally below the legal reaction time of 0.1 seconds. Christie and his coach, Ron Roddan, both claimed that the false starts were due to Christie's exceptional reaction times being under the legal time. His frequent false starting eventually led to his disqualification from the 1996 Summer Olympics 100 m final in Atlanta, US due to a second false start by Christie. Since January 2010, under WA rules, a single false start by an athlete results in disqualification.

In 2012, a new development to the false start rule was added. Because certain athletes could be disqualified for twitching in the starting blocks but some athletes could make a twitch without the starter noticing and disqualifying the athlete, it was decided that twitching in the starting block while being in the 'set' position would only carry a maximum penalty of a yellow card or a warning. In order to instantly be disqualified for a false start, an athlete's hands must leave the track or their feet must leave the starting blocks, while the athlete is in their final 'set' position.

Lanes

The finish of the 1987 East German athletics championships

For all Olympic sprint events, runners must remain within their pre-assigned lanes, which measure 1.22 metres (4 feet) wide, from start to finish. [31] The lanes can be numbered 1 through 8, 9, or rarely 10, starting with the inside lane. Any athlete who runs outside the assigned lane to gain an advantage is subject to disqualification. If the athlete is forced to run outside of his or her lane by another person, and no material advantage is gained, there will be no disqualification. Also, a runner who strays from his or her lane in the straightaway, or crosses the outer line of his or her lane on the bend, and gains no advantage by it, will not be disqualified as long as no other runner is obstructed.

The finish

The first athlete whose torso reaches the vertical plane of the closest edge of the finish line is the winner. To ensure that the sprinter's torso triggers the timing impulse at the finish line rather than an arm, foot, or other body part, a double Photocell is commonly used. Times are only recorded by an electronic timing system when both of these Photocells are simultaneously blocked. Photo finish systems are also used at some track and field events.

Sprint training

While genetics play a large role in one's ability to sprint, [114] [115] [116] athletes must be dedicated to their training to ensure that they can optimize their performances. Sprint training includes various running workouts, targeting acceleration, speed development, speed endurance, special endurance, and tempo endurance. Additionally, athletes perform intense strength training workouts, as well as plyometric or jumping workouts. Collectively, these training methods produce qualities which allow athletes to be stronger, more powerful, in hopes of ultimately running faster. [117]

Hurdling Group of track and field events

Hurdling is the act of jumping over an obstacle at a high speed or in a sprint. In the early 19th century, hurdlers ran at and jumped over each hurdle, landing on both feet and checking their forward motion. Today, the dominant step patterns are the 3-step for high hurdles, 7-step for low hurdles, and 15-step for intermediate hurdles. Hurdling is a highly specialized form of obstacle racing, and is part of the sport of athletics. In hurdling events, barriers known as hurdles are set at precisely measured heights and distances. Each athlete must pass over the hurdles; passing under or intentionally knocking over hurdles will result in disqualification.

Katharine Merry

Katharine Merry is an English former sprinter. She won the bronze medal in the 400 metres at the 2000 Sydney Olympics and was the fastest woman in the world over 400 m in 2001, with her career best of 49.59 seconds. She also represented Great Britain at the 1996 Atlanta Olympics and won the 200 metres at the 1993 European Junior Championships.

800 metres Middle-distance running event

The 800 metres, or meters, is a common track running event. It is the shortest commonly run middle-distance running event. The 800 metres is run over two laps of an outdoor (400-metre) track and has been an Olympic event since the first modern games in 1896. During the winter track season the event is usually run by completing four laps of an indoor 200-metre track.

400 metres hurdles Track and field hurdling event

The 400 metres hurdles is a track and field hurdling event. The event has been on the Olympic athletics programme since 1900 for men and since 1984 for women.

400 metres Sprint running event

The 400 metres, or 400-metre dash, is an endurance race event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440-yard dash (402.336 m)—which is a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete.

100 metres Sprint race

The 100 metres, or 100-metre dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, the 100-metre 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 World Championships 100 metres has been contested since 1983.

200 metres Sprint running event

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

60 metres

60 metres, or 60-meter dash, is a sprint event in track and field. It is a championship event for indoor championships, normally dominated by the best outdoor 100 metres runners. At outdoor venues it is a rare distance, at least for senior athletes. The format of the event is similar to other sprint distances. The sprinters follow three initial instructions: 'ready', instructing them to take up position in the starting blocks; 'set', instructing them to adopt a more efficient starting posture, which also isometrically preloads their muscles. This will enable them to start faster. The final instruction is the firing of the starter's pistol. Upon hearing this the sprinters stride forwards from the blocks.

1500 metres Middle distance running event, "the metric mile"

The 1500 metres or 1,500-metre run is the foremost middle distance track event in athletics. The distance has been contested at the Summer Olympics since 1896 and the World Championships in Athletics since 1983. It is equivalent to 1.5 kilometers or approximately 1516 miles.

10,000 metres Common long distance running event

The 10,000 metres or the 10,000-metre run is a common long-distance track running event. The event is part of the athletics programme at the Olympic Games and the World Athletics Championships, and is common at championship level events. The race consists of 25 laps around an Olympic-sized track. It is less commonly held at track and field meetings, due to its duration. The 10,000-metre track race is usually distinguished from its road running counterpart, the 10K run, by its reference to the distance in metres rather than kilometres.

110 metres hurdles Track and field hurdling event

The 110 metres hurdles, or 110-metre hurdles, is a hurdling track and field event for men. It is included in the athletics programme at the Summer Olympic Games. The female counterpart is the 100 metres hurdles. As part of a racing event, ten hurdles of 1.067 metres in height are evenly spaced along a straight course of 110 metres. They are positioned so that they will fall over if bumped into by the runner. Fallen hurdles do not carry a fixed time penalty for the runners, but they have a significant pull-over weight which slows down the run. Like the 100 metres sprint, the 110 metres hurdles begins in the starting blocks.

100 metres hurdles Track and field event

The 100 metres hurdles, or 100-meter hurdles, is a track and field event run mainly by women. For the race, ten hurdles of a height of 83.8 centimetres (33.0 in) are placed along a straight course of 100 metres (109.36 yd). The first hurdle is placed after a run-up of 13 metres from the starting line. The next 9 hurdles are set at a distance of 8.5 metres from each other, and the home stretch from the last hurdle to the finish line is 10.5 metres long. The hurdles are set up so that they will fall over if bumped into by the runner, but weighted so this is disadvantageous. Fallen hurdles do not count against runners provided that they do not run into them on purpose. Like the 100 metres sprint, the 100 m hurdles begins with athletes in starting blocks.
