Diving is the sport of jumping or falling into water from a platform or
springboard, usually while performing acrobatics. Diving is an internationally
recognised sport that is part of the Olympic Games. In addition, unstructured
and non-competitive diving is a recreational pastime.

Competitors possess many of the same characteristics as gymnasts and dancers,
including strength, flexibility, kinaesthetic judgement and air awareness. Some
professional divers were originally gymnasts or dancers as both the sports have
similar characteristics to diving. Dmitri Sautin holds the record for most
Olympic diving medals won, by winning eight medals in total between 1992 and
2008.[1]

HISTORY

[edit]


ANTIQUITY

[edit]

In the Tomb of Hunting and Fishing there is a wall painting from around 530 -
500 BCE[2][3] [4][5] that shows a person climbing rocks towards a cliff face and
a second person diving down the cliff face towards water.[6]

The Tomb of the Diver in Paestum, contains a fresco dating to around 500 to 475
BCE[7] that also shows a scene of a person diving into a pool or stream of
water[7][8] from a structure.

PLUNGING

[edit]
Plunging, the first competitive diving sport

Although diving has been a popular pastime across the world since ancient times,
the first modern diving competitions were held in England in the 1880s. The
exact origins of the sport are unclear, though it likely derives from the act of
diving at the start of swimming races.[9][10]

In the seventeenth century gymnasts moved their equipment to the beaches and
"performed acrobatics over the water."[11]

The 1904 book Swimming by Ralph Thomas notes English reports of plunging records
dating back to at least 1865.[12] The 1877 edition to British Rural Sports by
John Henry Walsh makes note of a "Mr. Young" plunging 56 feet (17 m) in 1870,
and also states that 25 years prior, a swimmer named Drake could cover 53 feet
(16 m).[13]

The English Amateur Swimming Association (at the time called the Swimming
Association of Great Britain) first started a "plunging championship" in
1883.[14][15] The Plunging Championship was discontinued in 1937.


FANCY DIVING

[edit]
A man dives into the Great South Bay of Long Island.

Diving into a body of water had also been a method used by gymnasts in Germany
and Sweden since the early 19th century. The soft landing allowed for more
elaborate gymnastic feats in midair as the jump could be made from a greater
height. This tradition evolved into 'fancy diving', while diving as a
preliminary to swimming became known as 'Plain diving'.

In England, the practice of high diving – diving from a great height – gained
popularity; the first diving stages were erected at the Highgate Ponds at a
height of 15 feet (4.6 m) in 1893 and the first world championship event, the
National Graceful Diving Competition, was held there by the Royal Life Saving
Society in 1895. The event consisted of standing and running dives from either
15 or 30 feet (4.6 or 9.1 m).

It was at this event that the Swedish tradition of fancy diving was introduced
to the sport by the athletes Otto Hagborg and C F Mauritzi. They demonstrated
their acrobatic techniques from the 10 m diving board at Highgate Pond and
stimulated the establishment of the Amateur Diving Association in 1901, the
first organisation devoted to diving in the world (later amalgamated with the
Amateur Swimming Association). Fancy diving was formally introduced into the
championship in 1903.[16][17]


OLYMPIC ERA

[edit]

Olympiad

Plain diving was first introduced into the Olympics at the 1904 event.[18] The
1908 Olympics in London added 'fancy diving' and introduced elastic boards
rather than fixed platforms. Women were first allowed to participate in the
diving events for the 1912 Olympics in Stockholm.[16]

In the 1928 Olympics, 'plain' and 'fancy' diving were amalgamated into one event
– 'Highboard Diving'. The diving event was first held indoors in the Empire Pool
for the 1934 British Empire Games and 1948 Summer Olympics in London.


COMPETITIVE DIVING

[edit]

Most diving competitions consist of three disciplines: 1 m and 3 m springboards,
and the platform. Competitive athletes are divided by gender, and often by age
group. In platform events, competitors are allowed to perform their dives on
either the five, seven and a half (generally just called seven), nine, or ten
meter towers. In major diving meets, including the Olympic Games and the World
Championships, platform diving is from the 10 meter height.

Divers have to perform a set number of dives according to established
requirements, including somersaults and twists. Divers are judged on whether and
how well they completed all aspects of the dive, the conformance of their body
to the requirements of the dive, and the amount of splash created by their entry
to the water. A possible score out of ten is broken down into three points for
the takeoff (meaning the hurdle), three for the flight (the actual dive), and
three for the entry (how the diver hits the water), with one more available to
give the judges flexibility.

The raw score is multiplied by a degree of difficulty factor, derived from the
number and combination of movements attempted. The diver with the highest total
score after a sequence of dives is declared the winner.


SYNCHRONIZED DIVING

[edit]
A man and a woman perform synchronised diving in Brazil, 2014.

Synchronized diving was adopted as an Olympic sport in 2000. Two divers form a
team and perform dives simultaneously. The dives are identical. It used to be
possible to dive opposites, also known as a pinwheel, but this is no longer part
of competitive synchronised diving. For example, one diver would perform a
forward dive and the other an inward dive in the same position, or one would do
a reverse and the other a back movement. In these events, the diving would be
judged both on the quality of execution and the synchronicity – in timing of
take-off and entry, height and forward travel.


SCORING THE DIVE

[edit]

There are rules governing the scoring of a dive. Usually a score considers three
elements of the dive: the approach, the flight, and the entry. The primary
factors affecting the scoring are:

 * if a hand-stand is required, the length of time and quality of the hold
 * the height of the diver at the apex of the dive, with extra height resulting
   in a higher score
 * the distance of the diver from the diving apparatus throughout the dive (a
   diver must not be dangerously close, should not be too far away, but should
   ideally be within 2 feet (0.61 m) of the platform)
 * the properly defined body position of the diver according to the dive being
   performed, including pointed toes and feet touching at all times
 * the proper amounts of rotation and revolution upon completion of the dive and
   entry into the water
 * angle of entry – a diver should enter the water straight, without any angle.
 * amount of splash – many judges award divers for the amount of splash created
   by the diver on entry, with less splash resulting in a higher score.

Each dive is assigned a degree of difficulty (DD),[19] which is determined from
a combination of the moves undertaken, position used, and height. The DD value
is multiplied by the scores given by the judges.

To reduce the subjectivity of scoring in major meets, panels of five or seven
judges are assembled; major international events such as the Olympics use
seven-judge panels. For a five-judge panel, the highest and lowest scores are
discarded and the middle three are summed and multiplied by the DD. For
seven-judge panels, as of the 2012 London Olympics, the two highest scores and
two lowest are discarded, leaving three to be summed and multiplied by the DD.
(Prior to the London Olympics, the highest and lowest scores were eliminated,
and the remaining five scores were multiplied by 3⁄5, to allow for comparison to
five-judge panels.) The cancelling of scores is used to make it difficult for a
single judge to manipulate scores.

There is a general misconception about scoring and judging. In serious meets,
the absolute score is somewhat meaningless. It is the relative score, not the
absolute score that wins meets. Accordingly, good judging implies consistent
scoring across the dives. Specifically, if a judge consistently gives low scores
for all divers, or consistently gives high scores for the same divers, the
judging will yield fair relative results and will cause divers to place in the
correct order. However, absolute scores have significance to the individual
divers. Besides the obvious instances of setting records, absolute scores are
also used for rankings and qualifications for higher level meets.

In synchronised diving events, there is a panel of seven, nine, or eleven
judges; two or three to mark the execution of one diver, two or three to mark
the execution of the other, and the remaining three or five to judge the
synchronisation. The execution judges are positioned two on each side of the
pool, and they score the diver which is nearer to them. The 2012 London Olympics
saw the first use of eleven judges.

The score is computed similarly to the scores from other diving events, but has
been modified starting with the 2012 London Olympics for the use of the larger
judging panels. Each group of judges will have the highest and lowest scores
dropped, leaving the middle score for each diver's execution and the three
middle scores for synchronisation. The total is then weighted by 3⁄5 and
multiplied by the DD. The result is that the emphasis is on the synchronisation
of the divers.

The synchronisation scores are based on:

 * time of take-off
 * height attained
 * synchronisation of rotations and twists
 * time of entry to the water
 * forward travel from the board

The judges may also disqualify the diver for certain violations during the dive,
including:

 * receiving a score of 0 on all dives performed in the event
 * improper equipment usage (e.g., female divers not using hair ties)


COMPETITIVE STRATEGY

[edit]
Mixed gender participants of synchronised swimming performing a dive

To win dive meets, divers create a dive list in advance of the meet. To win the
meet the diver must accumulate more points than other divers. Often, simple
dives with low DDs will look good to spectators but will not win meets. The
competitive diver will attempt the highest DD dives possible with which they can
achieve consistent, high scores. If divers are scoring 8 or 9 on most dives, it
may be a sign of their extreme skill, or it may be a sign that their dive list
is not competitive, and they may lose the meet to a diver with higher DDs and
lower scores.

In competition, divers must submit their lists beforehand, and once past a
deadline (usually when the event is announced or shortly before it begins) they
cannot change their dives. If they fail to perform the dive announced, even if
they physically cannot execute the dive announced or if they perform a more
difficult dive, they will receive a score of zero. Under exceptional
circumstances, a redive may be granted, but these are exceedingly rare (usually
for very young divers just learning how to compete, or if some event outside the
diver's control has caused them to be unable to perform-such as a loud noise).

In the Olympics or other highly competitive meets, many divers will have nearly
the same list of dives as their competitors. The importance for divers competing
at this level is not so much the DD, but how they arrange their list. Once the
more difficult rounds of dives begin it is important to lead off with a
confident dive to build momentum. They also tend to put a very confident dive in
front of a very difficult dive to ensure that they will have a good mentality
for the difficult dive. Most divers have pre-dive and post-dive rituals that
help them either maintain or regain focus. Coaches also play a role in this
aspect of the sport. Many divers rely on their coaches to help keep their
composure during the meet. In a large meet coaches are rarely allowed on the
deck to talk to their athlete so it is common to see coaches using hand gestures
or body movements to communicate.

There are some American meets which will allow changes of the position of the
dive even after the dive has been announced immediately before execution, but
these are an exception to the rules generally observed internationally.

Generally, NCAA rules allow for dives to be changed while the diver is on the
board, but the diver must request the change directly after the dive is
announced. This applies especially in cases where the wrong dive is announced.
If the diver pauses during his or her hurdle to ask for a change of dive, it
will be declared a ulk (when the diver stops mid-hurdle) and the change of dive
will not be permitted.

Under FINA law, no dive may be changed after the deadline for the dive-sheet to
be submitted (generally a period ranging from one hour to 24 hours, depending on
the rulings made by the event organiser).

It is the diver's responsibility to ensure that the dive-sheet is filled in
correctly, and also to correct the referee or announcer before the dive if they
describe it incorrectly. If a dive is performed which is as submitted but not as
(incorrectly) announced, it is declared failed and scores zero according to a
strict reading of the FINA law. But in practice, a re-dive would usually be
granted in these circumstances.


GOVERNANCE

[edit]

swimming, waves to the crowd before diving into water.

The global governing body of diving is FINA, which also governs swimming,
synchronised swimming, water polo and open water swimming. Almost invariably, at
national level, diving shares a governing body with the other aquatic sports.

This is frequently a source of political friction as the committees are
naturally dominated by swimming officials who do not necessarily share or
understand the concerns of the diving community. Divers often feel, for example,
that they do not get adequate support over issues like the provision of
facilities. Other areas of concern are the selection of personnel for the
specialised Diving committees and for coaching and officiating at events, and
the team selection for international competitions.

There are sometimes attempts to separate the governing body as a means to
resolve these frustrations, but they are rarely successful. For example, in the
UK the Great Britain Diving Federation was formed in 1992 with the intention of
taking over the governance of Diving from the ASA (Amateur Swimming
Association). Although it initially received widespread support from the diving
community, the FINA requirement that international competitors had to be
registered with their National Governing Body was a major factor in the
abandonment of this ambition a few years later.

Since FINA refused to rescind recognition of the ASA as the British governing
body for all aquatic sports including diving, this meant that the elite divers
had to belong to ASA-affiliated clubs to be eligible for selection to
international competition.

In the United States scholastic diving is almost always part of the school's
swim team. Diving is a separate sport in Olympic and Club Diving. The NCAA will
separate diving from swimming in special diving competitions after the swim
season is completed.


SAFETY

RECREATIONAL DIVING

[edit]

After an incident in Washington in 1993, most US and other pool builders are
reluctant to equip a residential swimming pool with a diving springboard so home
diving pools are much less common these days. In the incident, 14-year-old Shawn
Meneely made a "suicide dive" (holding his hands at his sides, so that his head
hit the bottom first) in a private swimming pool and became a tetraplegic. The
lawyers for the family, Jan Eric Peterson and Fred Zeder, successfully sued the
diving board manufacturer, the pool builder, and the National Spa and Pool
Institute over the inappropriate depth of the pool.[20][21] The NSPI had
specified a minimum depth of 7 ft 6 in (2.29 m) which proved to be insufficient
in the above case. The pool into which Meneely dived was not constructed to the
published standards. The standards had changed after the diving board was
installed on the non-compliant pool by the homeowner. But the courts held that
the pool "was close enough" to the standards to hold NSPI liable. The
multimillion-dollar lawsuit was eventually resolved in 2001 for US$6.6 million
($8 million after interest was added) in favour of the plaintiff.[22] The NSPI
was held to be liable, and was financially strained by the case. It filed twice
for Chapter 11 bankruptcy protection and was successfully reorganised into a new
swimming pool industry association.[20]


SPINAL CORD INJURIES

[edit]
Further information: Spinal cord injury, Paraplegia, and Quadriplegia

It has been commented that for spinal cord injuries related to diving board use
in the United States[23] that "For the purposes of obtaining rough estimates of
diving board-related injury risks," the estimated "...rate of SCI [Spinal Cord
Injury] due to diving into swimming pools from diving boards to be on the order
of 0.028 per 100,000 swimmers..."[23][24]


SUBMERGED OBJECTS

[edit]
See also: Cliff jumping § Dangers

Many diving accidents occur when divers do not account for submerged objects in
the water such as rocks and logs.[25] Because of this many beaches and pools
prohibit diving in shallow waters or when a lifeguard is not on duty.[26] It was
commetend that "...shallow dives can end up in death or permanent injury."[27]
and that in 1988 on lake powell a person "...was left a quadriplegic after
diving just 5 feet off a houseboat into the murky lake."[27]


IMPACT WITH WATER

[edit]

Water resistance increases with the speed of entry, so entering the water at
high-velocity induces rapid deceleration.[28][27] Jumping into water from a
height of 20 feet (6.1 m) results in a person impacting with the water surface
at 25 mph (40 km/h).[28] Impacting with the water surface at this velocity is
capable of giving a person temporary paralysis of the diaphragm,[27] a
compressed spine, broken bones, or concussion.[29][28]

The speed that a diver is travelling at the water surface when they dive from a
ten-metre platform is around 35 mph[29] and when a diver hits the water flat
from 10 metres they are brought to rest in about 1 ft. The extreme deceleration
when hitting the water flat at around 35 mph can cause severe bruising both
internal and external, strains to connective tissue securing the organs,
possible minor haemorrhaging to lungs and other tissues possibly resulting in a
person coughing up blood,[30] a compressed spine, broken bones, or
concussion.[29][28] This is very painful and distressing, but not
life-threatening.

Tom Daley has described one concussion that occurred to him "I missed my hands
before the Beijing World Series and smashed my head at 35mph on to the
water...".[29] The concussion resulted in him receiving "headaches, nausea,
dizziness...".[29] It also resulted in Daley being "...out of action for six
days and left him unable to dive off his competition height of 10m for three
weeks."[29]

It was commented that in 1989 a 22-year-old, who was a "...diver and a member of
the Salt Lake Country Club diving team... ...climbed up on a set of towering
rocks... ...about 60 feet..."[27] (18.2 metres). He dove into the water doing a
"back flip."[27] He never surfaced from the water and was found several days
later 120 feet below the surface.[27] The 22-year-old was found to have suffered
a broken neck.[27]


COMPETITIVE DIVING

[edit]

In competitive diving, FINA takes regulatory steps to ensure that athletes are
protected from the inherent dangers of the sport. For example, they impose
restrictions according to age on the heights of platforms which divers may
compete on.

 * Group D (11 & under): 5 m
 * Group C (12/13 year): 5 m & 7.5 m
 * Group B (14/15 year): 5 m, 7.5 m & 10 m
 * Group A (16/18 year): 5 m, 7.5 m & 10 m

Group D divers have only recently been allowed to compete on the tower. In the
past, the age group could compete only springboard, to discourage children from
taking on the greater risks of tower diving. Group D tower was introduced to
counteract the phenomenon of coaches pushing young divers to compete in higher
age categories, thus putting them at even greater risk.

However, some divers may safely dive in higher age categories to dive on higher
platforms. Usually this occurs when advanced Group C divers wish to compete on
the 10 m.

Points on pool depths in connection with diving safety:

 * most competition pools are 5 m deep for 10 m platform and 4 m deep for 5 m
   platform or 3 m springboard. These are currently the FINA recommended minimum
   depths, however some pools are deeper. The deepest diving pool in Europe is
   in Ponds Forge International Sports Centre at 5.85 m.
 * diving from 10 m and maintaining a downward streamlined position results in
   gliding to a stop at about 4.5–5 m.
 * high standard competition divers rarely go more than about 2.5m below the
   surface, as they roll in the direction of the dive's rotation. This is a
   technique to produce a clean entry.


COMPETITIVE DIVING INJURIES

[edit]

It has been commented that "Competitive diving poses unique risks for both
traumatic and overuse injuries in practice and competition."[31] It was
commented further that "Head, cervical spine, shoulder, and lumbar spine
injuries among others are not uncommon, though rates vary significantly in the
literature. Existing data suggest that as the level of competition elevates,
traumatic injuries (including head injury) become relatively less common, while
overuse injuries predominate."[31]

It has also been commented that "The most frequently injured areas are the
wrist, shoulder, and lumbar spine."[32]

When looking at "...(NCAA) swimming and diving injuries from 2009 to 2014...
...[it was found that there was] an injury rate of 1.94 injuries per 1000
athlete exposures (AE) for males and 2.49 injuries per 1000 AE for females, with
more injuries happening during practice over competition."[6] It has also been
found that "...2.1% of divers were injured in the 2008 Olympics... [and] ...8.1%
of divers were injured in the 2012 Olympics."[6] It was further found that
"...during the (FINA) World Championships of 2015, 2013, and 2009... ...older
athletes in the diving, high diving, and water polo groups were in the highest
risk group for injury."[6]

In relation to springboard diving it has been commented that "The
injury-producing forces during the takeoff are related to jumping and
deceleration... ...The most common injuries related to this part of the dive are
patellar tendinitis, patellar tracking problems, quadriceps tendinitis, Jumper’s
knee and patellofemoral compression syndrome commonly caused by repetitive
stress placed on the patellar or quadriceps tendon during jumping. Vertical jump
ability, as well as jumping and landing technique, are believed to influence
tendon loading."[33]

It has also been commented that 10-metre platform diving can also "...cause
repetitive strain injuries from repeatedly pushing off the concrete
platform."[34]

It has further been commented that "Concussions are relatively common, as are
pulmonary contusions in which the force of impact bruises the lungs."[34] Other
injuries that may occur include torn triceps muscles,[34] torn ACL ligaments[34]
and lower back issues.[34]

When entering the water divers spread their arms and somersault "...either
forward or backward underwater...[giving] the illusion of a vertical entry and
pull extra water down that hole with them in a maneuver that stresses lower back
muscles and hip flexors."[34] When divers performs this underwater somersault,
it is extremely inadvisable to attempt to scoop the trajectory underwater
against the rotation as it can cause serious back injuries.

Injuries that diver Tom Daley has received include "...concussions, torn
triceps, broken ribs, [as well as having] coughed up blood."[30] Tom also has a
scar on the top of his head[35] from hitting his head on the diving board.

Tom has also described the deterioration of a knee injury that he received;
"During the first lockdown in 2020 I’d torn some cartilage in my knee, but there
was no pain and I continued to train. Just when the Olympics was only eight
weeks away my knee got tighter and tighter, like a screw being turned. It became
locked in a position and I couldn’t straighten it or bend it... ...We booked a
scan. We thought maybe it just needed an injection to get it moving again. The
doctor also mooted the idea that it might need keyhole surgery. From there I was
sent for an MRI scan. From the scan, we could see that the cartilage had not
only torn, it had also flipped up and the joint had come back down on top of
it... ...It can be flattened and sewn back down, but the surgeon described it as
being a bit like a bent credit card that may snap up again or cause more
problems. The only other way to fix the problem was to take it out. “There is a
recovery time of four to six weeks,” the doctor said... ...A couple of weeks
after surgery, I was back in the pool, building my diving back up again."[36]


COMPETITIVE DIVING DEATHS

[edit]

In 1983, at the World University Games in Edmonton, Canada, diver Sergei
Chalibashvili, aged 21, died when he was attempting a reverse 3 1/2-somersault
and his head collided with the hardwood 10 metre diving platform.[37] After the
accident he was taken to hospital and died a week later.[37]

In 1987 during training diver Nathan Meade, aged 21, died when he struck his
head on a 10 metre concrete platform.[38] The dive he was attempting was a
reverse 2 1/2 somersault.[38]


DIVE GROUPS

[edit]
This section does not cite any sources. Please help improve this section by
adding citations to reliable sources. Unsourced material may be challenged and
removed. (February 2023) (Learn how and when to remove this message)

A male diver performs a reverse in the tuck position from a 3-meter springboard.

There are six "groups" into which dives are classified: Forward, Back, Inward,
Reverse, Twist, and Armstand. The armstand group applies only to Platform
competitions, whereas the other five groups apply to both Springboard and
Platform.

 * in the Forward Group (Group 1), the diver takes off facing forward and
   rotates forward
 * in the Back Group (2), the diver takes off with their back to the water and
   rotates backward
 * in the Reverse Group (3), the diver takes off facing forward and rotates
   backward
 * in the Inward Group (4), the diver takes off with their back to the water and
   rotates forward
 * any dive incorporating an axial twisting movement is in the Twist group (5)
 * any dive commencing from a handstand is in the Armstand group (6) (only on
   platform)




DIVE POSITIONS

[edit]

During the flight of the dive, one of four positions is assumed:

 * straight – with no bend at the knees or hips (the hardest of the four)
 * pike – with knees straight but a tight bend at the hips (the median in
   difficulty of the four). The open pike is a variant where the arms are
   reached to the side, and the legs are brought straight out with a bend in the
   hips.
 * tuck – body folded up in a tight ball, hands holding the shins and toes
   pointed (the easiest of the four)
 * free – indicates a twisting dive, and a combination of other positions. In
   the transition between two positions the diver may for example bend their
   legs or curve at the waist, and points will not be deducted for doing so.

These positions are referred to by the letters A, B, C and D respectively.

Additionally, some dives can be started in a flying position. The body is kept
straight with the arms extended to the side, and the regular dive position is
assumed at about half the dive.

Difficulty is rated according to the Degree of Difficulty of the dives. Some
divers may find pike easier in a flip than tuck, and most find straight the
easiest in a front/back dive, although it is still rated the most difficult
because of the risk of overrotation.

An armstand dive may have a higher degree of difficulty outdoors compared to
indoors as wind can destabilise the equilibrium of the diver.


DIVE NUMBERS

[edit]

In competition, the dives are referred to by a schematic system of three- or
four-digit numbers. The letter to indicate the position is appended to the end
of the number.

The first digit of the number indicates the dive group as defined above.

For groups 1 to 4, the number consists of three digits and a letter of the
alphabet. The third digit represents the number of half-somersaults. The second
digit is either 0 or 1, with 0 representing a normal somersault, and 1
signifying a "flying" variation of the basic movement (i.e. the first half
somersault is performed in the straight position, and then the pike or tuck
shape is assumed). No flying dive has been competed at a high level competition
for many years.

For example:

 * 101A – forward Dive Straight
 * 203C – back one-and-a-half somersaults, tuck
 * 305C – reverse two-and-a-half somersaults, tuck
 * 113B – flying forward one-and-a-half somersaults, pike
 * 104C – front double somersaults, tuck

For Group 5, the dive number has 4 digits. The first digit indicates that it is
a twisting dive. The second digit indicates the group (1–4) of the underlying
movement; the third digit indicates the number of half-somersaults, and the
fourth indicates the number of half-twists.

For example:

 * 5211A – back dive, half twist, straight position.
 * 5337D – reverse one and a half somersaults with three and a half twists, in
   the Free position.

For Group 6 – Armstand – the dive number has either three or four digits: Three
digits for dives without twist and four for dives with twists.

In non-twisting armstand dives, the second digit indicates the direction of
rotation (0 = no rotation, 1 = forward, 2 = backward, 3 = reverse, 4 = inward)
and the third digit indicates the number of half-somersaults. Inward-rotating
armstand dives have never been performed, and are generally regarded as
physically impossible.

For example:

 * 600A – armstand dive straight
 * 612B – armstand forward somersault pike
 * 624C – armstand back double somersault tuck

For twisting Armstand dives, the dive number again has 4 digits, but rather than
beginning with the number 5, the number 6 remains as the first digit, indicating
that the "twister" will be performed from an Armstand. The second digit
indicates the direction of rotation – as above, the third is the number of
half-somersaults, and the fourth is the number of half-twists:

e.g. 6243D – armstand back double-somersault with one and a half twists in the
free position

All of these dives come with DD (degree of difficulty) this is an indication of
how difficult/complex a dive is. The score that the dive receives is multiplied
by the DD (also known as tariff) to give the dive a final score. Before a diver
competes they must decide on a "list" this is a number of optional dives and
compulsory dives. The optionals come with a DD limit. this means that a diver
must select X number of dives and the combined DD limit must be no more than the
limit set by the competition/organisation etc.

Until the mid-1990s the tariff was decided by the FINA diving committee, and
divers could only select from the range of dives in the published tariff table.
Since then, the tariff is calculated by a formula based on various factors such
as the number of twist and somersaults, the height, the group etc., and divers
are free to submit new combinations. This change was implemented because new
dives were being invented too frequently for an annual meeting to accommodate
the progress of the sport.


MECHANICS OF DIVING

[edit]
Fresco. Tomb of the Diver. Paestum, Italy. 470 BCE

At the moment of take-off, two critical aspects of the dive are determined, and
cannot subsequently be altered during the execution. One is the trajectory of
the dive, and the other is the magnitude of the angular momentum.

The speed of rotation – and therefore the total amount of rotation – may be
varied from moment to moment by changing the shape of the body, in accordance
with the law of conservation of angular momentum.

The center of mass of the diver follows a parabolic path in free-fall under the
influence of gravity (ignoring the effects of air resistance, which are
negligible at the speeds involved).[39]


TRAJECTORY

[edit]

Since the parabola is symmetrical, the travel away from the board as the diver
passes it is twice the amount of the forward travel at the peak of the flight.
Excessive forward distance to the entry point is penalised when scoring a dive,
but obviously an adequate clearance from the diving board is essential on safety
grounds.

The greatest possible height that can be achieved is desirable for several
reasons:

 * the height attained is itself one of the factors that the judges will reward.
 * a greater height gives a longer flight time and therefore more time to
   execute manoeuvres.
 * for any given clearance when passing the board, the forward travel distance
   to the entry point will be less for a higher trajectory.


CONTROL OF ROTATION

[edit]

The magnitude of angular momentum remains constant throughout the dive, but
since

angular momentum = rotational velocity × moment of inertia,

and the moment of inertia is larger when the body has an increased radius, the
speed of rotation may be increased by moving the body into a compact shape, and
reduced by opening out into a straight position.

Since the tucked shape is the most compact, it gives the most control over
rotational speed, and dives in this position are easier to perform. Dives in the
straight position are hardest, since there is almost no scope for altering the
speed, so the angular momentum must be created at take-off with a very high
degree of accuracy. (A small amount of control is available by moving the
position of the arms and by a slight hollowing of the back).

The opening of the body for the entry does not stop the rotation, but merely
slows it down. The vertical entry achieved by expert divers is largely an
illusion created by starting the entry slightly short of vertical, so that the
legs are vertical as they disappear beneath the surface. A small amount of
additional tuning is available by 'entry save' techniques, whereby underwater
movements of the upper body and arms against the viscosity of the water affect
the position of the legs.[40]


TWISTING

[edit]
A twisting dive performed from a 10-meter platform

Dives with multiple twists and somersaults are some of the most spectacular
movements, as well as the most challenging to perform.

The rules state that twisting "must not be generated manifestly on take-off".
Consequently, divers must use some of the somersaulting angular momentum to
generate twisting movements. The physics of twisting can be explained by looking
at the components of the angular momentum vector.

As the diver leaves the board, the total angular momentum vector is horizontal,
pointing directly to the left for a forward dive for example. For twisting
rotation to exist, it is necessary to tilt the body sideways after takeoff, so
that there is now a small component of this horizontal angular momentum vector
along the body's long axis. The tilt can be seen in the photo.

The tilting is done by the arms, which are outstretched to the sides just before
the twist. When one arm is moved up and the other is moved down (like turning a
big steering wheel), the body reacts by tilting to the side, which then begins
the twisting rotation. At the completion of the required number of twist
rotations, the arm motion is reversed (the steering wheel is turned back), which
removes the body's tilt and stops the twisting rotation.

An alternative explanation is that the moving arms have precession torque on
them which set the body into twisting rotation. Moving the arms back produces
opposite torque which stops the twisting rotation.


ENTRY

[edit]

The rules state that the body should be vertical, or nearly so, for entry.
Strictly speaking, it is physically impossible to achieve a literally vertical
position throughout the entry as there will inevitably still be some rotational
momentum while the body is entering the water. Divers therefore attempt to
create the illusion of being vertical, especially when performing rapidly
rotating multiple somersault movements. For back entries, one technique is to
allow the upper body to enter slightly short of vertical so that the continuing
rotation leaves the final impression of the legs entering vertically. This is
called "Knee save". Another is to use "Pike save" movements of scooping the
upper body underwater in the direction of rotation so as to counteract the
rotation of the legs. Knee saves are performed for back entries and Pike saves
are performed for front entries.

The arms must be beside the body for feet-first dives, which are typically
competed only on the 1m springboard and only at fairly low levels of 3m
springboard, and extended forwards in line for "head-first" dives, which are
much more common competitively. It used to be common for the hands to be
interlocked with the fingers extended towards the water, but a different
technique has become favoured during the last few decades. Now the usual
practice is for one hand to grasp the other with palms down to strike the water
with a flat surface. This creates a vacuum between the hands, arms and head
which, with a vertical entry, will pull down and under any splash until deep
enough to have minimal effect on the surface of the water (the so-called "rip
entry").

Once a diver is completely under the water they may choose to roll or scoop in
the same direction their dive was rotating to pull their legs into a more
vertical position. Apart from aesthetic considerations, it is important from a
safety point of view that divers reinforce the habit of rolling in the direction
of rotation, especially for forward and inward entries. Back injuries such as
hyperextension are caused by attempting to re-surface in the opposite direction.
Diving from the higher levels increases the danger and likelihood of such
injuries.

CANADA

[edit]
The DPC logo

In Canada, elite competitive diving is regulated by DPC (Diving Plongeon
Canada), although the individual provinces also have organizational bodies. The
main competitive season runs from February to July, although some competitions
may be held in January or December, and many divers (particularly international
level athletes) will train and compete year round.

Most provincial level competitions consist of events for six age groups (Groups
A, B, C, D, E, and Open) for both genders on each of the three board levels.
These age groups roughly correspond to those standardised by FINA, with the
addition of a youngest age group for divers 9 and younger, Group E, which does
not compete nationally and does not have a tower event (although divers of this
age may choose to compete in Group D). The age group Open is so called because
divers of any age, including those over 18, may compete in these events, so long
as their dives meet a minimum standard of difficulty.

Although Canada is internationally a fairly strong country in diving, the vast
majority of Canadian high schools and universities do not have diving teams, and
many Canadian divers accept athletic scholarships from American colleges.

Adult divers who are not competitive at an elite level may compete in masters
diving. Typically, masters are either adults who never practised the sport as
children or teenagers, or former elite athletes who have retired but still seek
a way to be involved in the sport. Many diving clubs have masters teams in
addition to their primary competitive ones, and while some masters dive only for
fun and fitness, there are also masters competitions, which range from the local
to world championship level.

NATIONAL CHAMPIONSHIPS

[edit]

Divers can qualify to compete at the age group national championships, or junior
national championships, in their age groups as assigned by FINA up to the age of
18. This competition is held annually in July. Qualification is based on
achieving minimum scores at earlier competitions in the season, although
athletes who place very highly at a national championship will be automatically
qualified to compete at the next. Divers must qualify at two different
competitions, at least one of which must be a level 1 competition, i.e. a
competition with fairly strict judging patterns. Such competitions include the
Polar Bear Invitational in Winnipeg, the Sting in Victoria, and the Alberta
Provincial Championships in Edmonton or Calgary. The qualifying scores are
determined by DPC according to the results of the preceding year's national
competition, and typically do not have much variation from year to year.

Divers older than 18, or advanced divers of younger ages, can qualify for the
senior national championships, which are held twice each year, once roughly in
March and once in June or July. Once again, qualification is based on achieving
minimum scores at earlier competitions (in this case, within the 12 months
preceding the national championships, and in an Open age group event), or high
placements in previous national championships or international competitions. It
is no longer the case that divers may use results from age group events to
qualify for senior nationals, or results from Open events to qualify for age
group nationals.


REPUBLIC OF IRELAND

[edit]

In the Republic of Ireland facilities are limited to one operational pool at the
National Aquatic Centre in Dublin. Other facilities with diving boards at the
University of Limerick are undergoing staff training in an effort to start
diving programmes.

NATIONAL CHAMPIONSHIPS

[edit]

National championships take place late in the year, usually during November. The
competition is held at the National Aquatic Centre in Dublin and consists of
four events:

 * Irish Open Age Group Championships
 * Irish Open Junior Diving Championships
 * Irish Open Senior Diving Championships
 * Novice Competition (8–18 yrs)


UNITED KINGDOM

[edit]

In the United Kingdom, diving competitions on all boards run throughout the
year. National Masters' Championships are held two or three times per year.


UNITED STATES

[edit]

SUMMER DIVING

[edit]

In the United States, summer diving is usually limited to one meter diving at
community or country club pools. Some pools organise to form intra-pool
competitions. These competitions are usually designed to accommodate all
school-age children.

HIGH SCHOOL DIVING

[edit]

In the United States scholastic diving at the high school level is usually
limited to one meter diving (but some schools use three meter springboards.).
Scores from those one meter dives contribute to the swim team's overall score.
High school diving and swimming concludes their season with a state competition.
Depending on the state and the number of athletes competing in the state,
certain qualifications must be achieved to compete in the state's championship
meet. There are often regional championships and district championships which
are necessary to compete in before reaching the state meet to narrow the field
to only the most competitive athletes. Most state championship meets consist of
eleven dives. The eleven dives are usually split up between two categories: five
required (voluntary) dives and six optional dives.

CLUB DIVING

[edit]

In the United States, pre-college divers interested in learning one and three
meter or platform diving should consider a club sanctioned by either USA Diving
or AAU Diving. In USA Diving, Future Champions is the entry level or novice
diver category with eight levels of competition. From Future Champions, divers
graduate to "Junior Olympic", or JO. JO divers compete in age groups at
inter-club competitions, at invitationals, and if qualified, at regional, zone
and national competitions. Divers over the age of 19 years of age cannot compete
in these events as a JO diver.

USA Diving sanctions the Winter Nationals championship with one, three meter,
and platform events. In the summer USA Diving sanctions the Summer Nationals
including all three events with both Junior and Senior divers. USA Diving is
sanctioned by the United States Olympic Committee to select team representatives
for international diving competitions including the World Championships and
Olympic Games.

AAU Diving sanctions one national event per year in the summer. AAU competes on
the one, three, and tower to determine the All-American team.

COLLEGE DIVING

[edit]
The University of Houston's CRWC Natatorium is home to the United States'
largest collegiate swimming pool.

In the United States scholastic diving at the college level requires one and
three meter diving. Scores from the one and three meter competition contribute
to the swim team's overall meet score. College divers interested in tower diving
may compete in the NCAA separate from swim team events. NCAA Divisions II and
III do not usually compete platform; if a diver wishes to compete platform in
college, he or she must attend a Division I school.

Each division also has rules on the number of dives in each competition.
Division II schools compete with 10 dives in competition whereas Division III
schools compete with 11. Division I schools only compete with 6 dives in
competition. These 6 dives consist of either 5 optionals and 1 voluntary, or 6
optionals. If the meet is a 5 optional meet, then the divers will perform 1
optional from each category (Front, Back, Inward, Reverse, and Twister) and then
1 voluntary from the category of their choice. The voluntary in this type of
meet is always worth a DD (Degree of Difficulty) of 2.0 even if the real DD is
worth more or less on a DD sheet. In a 6 optional meet, the divers will yet
again perform one dive from each category, but this time they will perform a 6th
optional from the category of their choosing, which is worth its actual DD from
the DD sheet.

The highest level of collegiate competition is the NCAA Division 1 Swimming and
Diving Championship. Events at the championship include 1 metre springboard, 3
metre springboard, and platform, as well as various swimming individual and
relay events. The points scored by swimmers and divers are combined to determine
a team swimming & diving champion. To qualify for a diving event at the NCAA
championships, a competitor must first finish in the top three at one of five
zone championships, which are held after the various conference championship
meets. A diver who scores at least 310 points on the 3 metre springboard and 300
points on the 1 metre springboard in a 6 optional meet can participate in the
particular zone championship corresponding to the geographic region in which his
or her school lies.

A number of colleges and universities offer scholarships to men and women who
have competitive diving skills. These scholarships are usually offered to divers
with age-group or club diving experience.

The NCAA limits the number of years a college student can represent any school
in competitions. The limit is four years, but could be less under certain
circumstances.

MASTERS' DIVING

[edit]

Divers who continue diving past their college years can compete in Masters'
Diving programs. Masters' diving programs are frequently offered by college or
club programs.

Masters' Diving events are normally conducted in age-groups separated by five or
ten years, and attract competitors of a wide range of ages and experience (many,
indeed, are newcomers to the sport); the oldest competitor in a Masters' Diving
Championship was Viola Krahn, who at the age of 101 was the first person in any
sport, male or female, anywhere in the world, to compete in an age-group of 100+
years in a nationally organised competition.


NON-COMPETITIVE DIVING

[edit]

Rivers, Glide, Oregon

Diving is also popular as a non-competitive activity. Such diving usually
emphasises the airborne experience, and the height of the dive, but does not
emphasise what goes on once the diver enters the water. The ability to dive
underwater can be a useful emergency skill, and is an important part of
watersport and navy safety training. Entering water from a height is an
enjoyable leisure activity, as is underwater swimming.

Such non-competitive diving can occur indoors and outdoors. Outdoor diving
typically takes place from cliffs or other rock formations either into fresh or
salt water. However, man-made diving platforms are sometimes constructed in
popular swimming destinations. Outdoor diving requires knowledge of the water
depth and currents as conditions can be dangerous. On occasion, the diver will
inadvertently belly flop, entering the water horizontally or nearly so. The
diver typically displaces a larger than usual amount of water.


HIGH DIVING

[edit]
Main article: High diving

A recently developing section of the sport is High Diving (e.g. see 2013 World
Aquatics Championships), conducted in open air locations, usually from
improvised platforms up to 89 feet (27 m) high (as compared with 33 feet (10 m)
as used in Olympic and World Championship events). Entry to the water is
invariably feet-first to avoid the risk of injury that would be involved in
head-first entry from that height. The final half-somersault is almost always
performed backwards, enabling the diver to spot the entry point and control
their rotation.

Competitive high diving is run as the Red Bull Cliff Diving World Series.
