Swimming and Aquatic Sports: Pool, Strokes and Indian Swimmers — GK24 title card

Swimming is one of the oldest competitive sports and the largest single discipline at the Olympic Games after athletics. In general knowledge papers it never appears as a vague chapter on fitness; it appears as a set of fixed numbers and names. How long is an Olympic pool, how many lanes does it have, in what order are the four strokes swum in a medley, how many players does a water polo team put in the water, who was the first Indian to cross the English Channel. This chapter collects those facts, together with the aquatic disciplines that sit beside swimming and the Indian names that papers return to again and again.

What counts as an aquatic sport

The world body for aquatic sports recognises six disciplines: swimming (in a pool), diving, water polo, artistic swimming (earlier called synchronised swimming), open water swimming and high diving. Five of the six are on the Olympic programme; high diving is contested at the World Aquatics Championships but not at the Olympics. Rowing, canoeing, kayaking, sailing and surfing are also played on water but are not aquatic sports in this sense: rowing is run by World Rowing, canoeing and kayaking by the International Canoe Federation, and sailing by World Sailing. Examiners build distractors out of exactly this confusion, so keep the list of six in mind.

The pool, the lanes and the strokes

A long-course or Olympic-size pool is 50 metres long and 25 metres wide. It is marked into 10 lanes, each 2.5 metres wide, of which the eight middle lanes are used for racing while the two outside lanes absorb the wash. The minimum depth for Olympic competition is 2 metres, and 3 metres is recommended. A short-course pool is 25 metres long, and world records are kept separately for long course and short course. Water temperature is held between 25 and 28 degrees Celsius. Touchpads at each end record the finish to a hundredth of a second, and a swimmer who leaves the starting block before the signal is disqualified for a false start.

Competitive swimming uses four strokes. Freestyle is unrestricted, so swimmers choose the front crawl, the fastest of all. Backstroke is the only stroke started in the water rather than from the block. Breaststroke is the slowest of the four and the most tightly regulated. Butterfly was separated from breaststroke in the early 1950s and became a separate Olympic event at the 1956 Melbourne Games. The order of the strokes is itself a favourite question, because it differs between the two medley events.

EventOrder of strokes
Individual medley (200 m and 400 m)Butterfly, backstroke, breaststroke, freestyle
Medley relay (4 x 100 m)Backstroke, breaststroke, butterfly, freestyle

The Olympic swimming programme

Freestyle is raced over 50, 100, 200, 400, 800 and 1500 metres. Backstroke, breaststroke and butterfly are each raced over 100 and 200 metres. The individual medley is swum over 200 and 400 metres, and the relays are the 4 x 100 metres freestyle, the 4 x 200 metres freestyle and the 4 x 100 metres medley. The longest race inside the pool is the 1500 metres freestyle, nicknamed the metric mile. Outside the pool, the 10 kilometre open water marathon swim was added to the Olympic programme at the 2008 Beijing Games.

Swimming has been on the programme of every modern Olympic Games since the first in Athens in 1896, where the races were held in the Bay of Zea; women's swimming was added at Stockholm in 1912. The American swimmer Michael Phelps is the most decorated Olympian in history with 28 medals, 23 of them gold, and his eight gold medals at Beijing in 2008 remain the most won by any athlete at a single Games, beating Mark Spitz's seven at Munich in 1972.

Diving, water polo and artistic swimming

Diving is contested from the 3 metre springboard and the 10 metre platform, with synchronised diving for pairs added at Sydney in 2000. A dive is judged on the approach, the take-off, the flight and the entry, and the positions are straight, pike, tuck and free. Water polo puts seven players from each side in the water, six field players and a goalkeeper, and a match runs for four quarters of eight minutes of actual play; it was introduced for men at the 1900 Paris Olympics, making it the first team sport at the modern Games, and a women's event was added at Sydney in 2000. Players stay upright using the eggbeater kick. Artistic swimming, an Olympic event since Los Angeles in 1984, is judged on execution and artistic impression, and swimmers may not touch the bottom of the pool.

Governing bodies and Indian swimmers

The international federation was founded in 1908 in London during the Olympic Games as the Federation Internationale de Natation, known by its initials FINA, and renamed World Aquatics in 2023. Its headquarters are in Lausanne, Switzerland. The national body is the Swimming Federation of India, formed in 1948, which governs swimming, diving and water polo in the country.

SwimmerWhy the papers ask
Mihir SenFirst Indian to swim across the English Channel, in 1958; later crossed five seas in one year
Arati SahaFirst Asian woman to swim across the English Channel, in 1959; first sportswoman awarded the Padma Shri
Bula ChoudhuryFirst woman to swim across the seven seas
Sachin NagWon the 100 m freestyle at the first Asian Games, Delhi 1951
Murlikant PetkarGold in the 50 m freestyle at the 1972 Heidelberg Paralympics, India's first Paralympic gold
Khazan Singh TokasSilver in the 200 m butterfly at the 1986 Seoul Asian Games

Terms worth memorising

  • Tumble turn or flip turn: the somersault turn used in freestyle and backstroke.
  • Eggbeater kick: the alternating circular leg action that keeps a water polo player upright.
  • Pike, tuck and straight: the body positions of a dive.
  • Metric mile: the 1500 metres freestyle.
  • False start: leaving the block before the starting signal, punished by disqualification.

Revise this chapter as a set of pairs rather than as prose: stroke and its order, event and its distance, swimmer and the first he or she achieved, discipline and its governing body. Almost every question set from aquatic sports is one of those pairs turned into four options.

Exam Point of View

Questions come as fixed pairs. Pool and lane measurements, the two medley orders (the commonest trap is giving the relay order for the individual medley), which stroke starts in the water, the longest pool event against the open water marathon, the number of players in water polo, the founding year and headquarters of World Aquatics, and the firsts of Indian swimmers. Sports-body questions mix in rowing, canoeing and sailing as false aquatic disciplines. Michael Phelps questions ask for either eight golds at one Games or twenty-eight medals in all, with Mark Spitz's seven as the distractor.

Practice MCQs on this topic

Q1.Sports GKEasy

What is the length of an Olympic-size (long course) swimming pool?

  1. A.25 metres
  2. B.33 metres
  3. C.50 metres
  4. D.100 metres
Show answer
Correct answer: C. 50 metres

Explanation

The correct answer is C, 50 metres. An Olympic-size or long course pool measures 50 metres in length and 25 metres in width, and all Olympic pool races are swum in it, so a 100 metre race means two lengths and the 1500 metre freestyle means thirty. Option A is wrong because 25 metres is the short course pool used for the World Short Course Championships and for most club meets; records set in it are listed separately from long course records. Option B is wrong because 33 metres matches no recognised standard, though pools of that rough size were used at some very early Olympic Games before the distance was fixed. Option D is wrong because no competition pool is 100 metres long; the 100 metre race is covered in two lengths of a long course pool. The width of 25 metres holds ten lanes of 2.5 metres each.

Q2.Sports GKMedium

How many lanes are marked in a pool used for Olympic swimming competition?

  1. A.Six
  2. B.Eight
  3. C.Ten
  4. D.Twelve
Show answer
Correct answer: C. Ten

Explanation

The correct answer is C, ten. A pool built to the long course standard is marked into ten lanes of 2.5 metres each across its 25 metre width. Only the eight middle lanes are used for racing; the two outside lanes are left empty so that the wash thrown up by the swimmers is absorbed rather than reflected back across the field. This is why a final has eight swimmers although the pool shows ten lanes, and why option B, eight, is the trap in this question: eight is the number of competitors and of racing lanes, not of lanes marked in the pool. Option A is wrong because six lane pools are common in schools and small clubs but not at this level. Option D is wrong because twelve lanes are not part of any aquatic standard. Lane ropes carry coloured floats to mark the last five metres before the wall.

Q3.Sports GKMedium

In the individual medley, in which order are the four strokes swum?

  1. A.Backstroke, breaststroke, butterfly, freestyle
  2. B.Butterfly, backstroke, breaststroke, freestyle
  3. C.Freestyle, butterfly, backstroke, breaststroke
  4. D.Breaststroke, butterfly, backstroke, freestyle
Show answer
Correct answer: B. Butterfly, backstroke, breaststroke, freestyle

Explanation

The correct answer is B, butterfly, backstroke, breaststroke, freestyle. One swimmer covers all four strokes in that fixed sequence over 200 or 400 metres, and freestyle is always last. Option A is the order of the medley relay, not of the individual medley, and it is the commonest mistake on this question: in a relay the backstroke leg must come first because backstroke is the only stroke started in the water, so the first swimmer can begin from the wall while the others take flying starts. Option C is wrong because freestyle, the fastest stroke, is deliberately placed at the end of both medleys to make the finish the quickest part of the race. Option D is wrong because breaststroke, the slowest stroke, is swum third in the individual medley and second in the relay, never first. Remember the pair of orders together, since papers often ask them in the same set.

Q4.Sports GKMedium

Which stroke is swum by the first swimmer in a 4 x 100 metre medley relay?

  1. A.Butterfly
  2. B.Breaststroke
  3. C.Backstroke
  4. D.Freestyle
Show answer
Correct answer: C. Backstroke

Explanation

The correct answer is C, backstroke. The medley relay order is backstroke, breaststroke, butterfly and freestyle, and the reason the sequence differs from the individual medley is practical. Backstroke is the only competitive stroke that begins in the water, with the swimmer holding the wall and the feet against it, so it must be given the first leg; the other three swimmers dive in as flying starts once their teammate touches. Option A is wrong because butterfly leads the individual medley but swims third in the relay. Option B is wrong because breaststroke takes the second leg of the relay and the third leg of the individual medley. Option D is wrong because freestyle is the anchor leg in both the medley relay and the individual medley, so that the fastest stroke decides the finish. Each of the four swimmers in a medley relay must swim a different stroke.

Q5.Sports GKEasy

Who was the first Asian woman to swim across the English Channel?

  1. A.Bula Choudhury
  2. B.Arati Saha
  3. C.Shikha Tandon
  4. D.Nisha Millet
Show answer
Correct answer: B. Arati Saha

Explanation

The correct answer is B, Arati Saha. The Bengali swimmer crossed the English Channel in September 1959, becoming the first woman from Asia to do so, and in 1960 she became the first Indian sportswoman to be awarded the Padma Shri. Option A is wrong but close enough to be the standard distractor: Bula Choudhury, also from Bengal, crossed the Channel three decades later and is remembered as the first woman to swim across the seven seas, a different record. Option C is wrong because Shikha Tandon is a pool swimmer, known for representing India at the 2004 Athens Olympics, not a Channel swimmer. Option D is wrong because Nisha Millet is likewise a pool and multi-national-medal swimmer of the same era. The male counterpart of this question is Mihir Sen, who crossed the Channel in 1958, a year before Arati Saha.

Q6.Sports GKMedium

Who was the first Indian to swim across the English Channel?

  1. A.Mihir Sen
  2. B.Taranath Shenoy
  3. C.Sachin Nag
  4. D.Khazan Singh Tokas
Show answer
Correct answer: A. Mihir Sen

Explanation

The correct answer is A, Mihir Sen. A lawyer from Bengal, he swam the English Channel in 1958 and went on to cross five major seas and straits in a single year, 1966, including the Palk Strait between India and Sri Lanka, the Strait of Gibraltar, the Dardanelles, the Bosphorus and the Panama Canal. He was honoured with the Padma Shri and later the Padma Bhushan. Option B is wrong because Taranath Shenoy was a celebrated deaf long-distance swimmer who crossed the Channel later and received the Padma Shri, but he was not the first Indian across. Option C is wrong because Sachin Nag was a pool sprinter who won the 100 metre freestyle at the first Asian Games in Delhi in 1951. Option D is wrong because Khazan Singh Tokas won a silver in the 200 metre butterfly at the 1986 Seoul Asian Games. The first person of any nationality to swim the Channel was Captain Matthew Webb in 1875.

Q7.Sports GKMedium

Which is the longest swimming race held inside the pool at the Olympic Games?

  1. A.800 metre freestyle
  2. B.1500 metre freestyle
  3. C.400 metre individual medley
  4. D.10 kilometre marathon swim
Show answer
Correct answer: B. 1500 metre freestyle

Explanation

The correct answer is B, the 1500 metre freestyle, often called the metric mile, which covers thirty lengths of a 50 metre pool and is the longest event on the Olympic pool programme. Option A is wrong because the 800 metre freestyle is shorter, though it is now held for both men and women; for many Games it was the women-only distance while 1500 metres was men-only. Option C is wrong because the 400 metre individual medley, demanding as it is, covers only eight lengths. Option D is a deliberate trap: the 10 kilometre marathon swim, added to the Olympic programme at Beijing in 2008, is indeed the longest Olympic swimming race of all, but it belongs to the open water discipline and is contested in a river, lake or sea, not in a pool. Read such questions for the words "in the pool" before answering.

Q8.Sports GKEasy

How many players of a water polo team are in the water at one time?

  1. A.Five
  2. B.Six
  3. C.Seven
  4. D.Eleven
Show answer
Correct answer: C. Seven

Explanation

The correct answer is C, seven: six field players and one goalkeeper, who is distinguished by a red cap while the two teams wear white and dark caps. Option A is wrong because five is the field strength in basketball, not water polo. Option B is wrong but is the standard trap, since six is the number of field players alone; the question asks for the whole side in the water, so the goalkeeper must be counted. Option D is wrong because eleven belongs to football, cricket and hockey, not to water polo. A match is played in four quarters of eight minutes of actual playing time, a team must shoot within a fixed possession period, and players use the eggbeater kick to stay upright with their hands free. Water polo was introduced for men at the Paris Olympics of 1900, making it the first team sport of the modern Games, and the women entered at Sydney in 2000.

Q9.Sports GKEasy

How many gold medals did Michael Phelps win at a single Olympic Games, the most by any athlete?

  1. A.Six
  2. B.Seven
  3. C.Eight
  4. D.Nine
Show answer
Correct answer: C. Eight

Explanation

The correct answer is C, eight. The American swimmer won eight gold medals at the Beijing Olympics of 2008, the most won by any athlete at one Games, and he closed his career as the most decorated Olympian in history with 28 medals, 23 of them gold. Option A is wrong because six is not associated with this record. Option B, seven, is the classic distractor: Mark Spitz of the United States won seven golds at Munich in 1972, a mark that stood for thirty-six years until Phelps passed it by one in Beijing. Option D is wrong because nine golds at a single Games has never been achieved; Phelps did, however, win nine individual Olympic golds over his whole career. Papers often pair this question with the number of medals Phelps won in total, so remember twenty-eight medals and twenty-three golds together.

Q10.Sports GKHard

Where is the headquarters of World Aquatics, the international federation for swimming formerly called FINA?

  1. A.Monaco
  2. B.Lausanne, Switzerland
  3. C.Paris, France
  4. D.London, United Kingdom
Show answer
Correct answer: B. Lausanne, Switzerland

Explanation

The correct answer is B, Lausanne in Switzerland, the city that also hosts the International Olympic Committee and many other world federations. The body was founded in 1908 in London during that year's Olympic Games, as the Federation Internationale de Natation, and the shortened form FINA stayed in use until it was renamed World Aquatics in 2023. Option A is wrong because Monaco houses World Athletics, a frequent source of confusion in this question. Option C is wrong because Paris, although the home of several sports bodies in the past, is not the seat of the aquatic federation. Option D is wrong but tempting, since London is where the federation was founded; the founding city and the present headquarters are different, and papers test precisely that gap. World Aquatics governs swimming, diving, water polo, artistic swimming, open water swimming and high diving.

Q11.Sports GKMedium

Which of the following is NOT one of the aquatic disciplines governed by World Aquatics?

  1. A.Water polo
  2. B.Artistic swimming
  3. C.Rowing
  4. D.High diving
Show answer
Correct answer: C. Rowing

Explanation

The correct answer is C, rowing. World Aquatics recognises six disciplines, namely swimming, diving, water polo, artistic swimming, open water swimming and high diving. Rowing is played on water but is governed by a separate international body, World Rowing, long known as FISA, and its Olympic events are listed under rowing, not aquatics. Option A is wrong as a choice because water polo is one of the six and was in fact the first team sport at the modern Olympic Games, in Paris in 1900. Option B is wrong because artistic swimming, called synchronised swimming until a recent change of name, has been an Olympic aquatic event since Los Angeles in 1984. Option D is wrong because high diving, from platforms far higher than the Olympic ten metres, is a World Aquatics discipline contested at the World Championships although not at the Olympics. Canoeing, kayaking and sailing are likewise outside aquatics.

Q12.Sports GKMedium

India's first Paralympic gold medal was won in which sport?

  1. A.Athletics
  2. B.Swimming
  3. C.Shooting
  4. D.Badminton
Show answer
Correct answer: B. Swimming

Explanation

The correct answer is B, swimming. Murlikant Petkar won the 50 metre freestyle at the 1972 Heidelberg Paralympic Games, and that remained India's only Paralympic gold for thirty-two years. Petkar, a former soldier disabled by bullet wounds in the 1965 war, also set a world record in the event. Option A is wrong but is the natural guess, because athletics has since given India several Paralympic golds, beginning with Devendra Jhajharia in the javelin at Athens in 2004; those came later. Option C is wrong because shooting brought India its first Paralympic shooting gold much later, at Tokyo in 2021. Option D is wrong because badminton entered the Paralympic programme only at the Tokyo Games. The question is often set beside its Olympic counterpart, where India's first individual gold came in shooting, through Abhinav Bindra at Beijing in 2008.

Frequently Asked Questions

Which is the fastest swimming stroke?

The front crawl, used in freestyle events because freestyle places no restriction on the stroke. Breaststroke is the slowest of the four competitive strokes, which is why freestyle is placed last and breaststroke in the middle of a medley.

Why does an Olympic pool have ten lanes when only eight swimmers race?

The two outside lanes are left empty so that the waves thrown up by the swimmers are absorbed instead of bouncing back across the racing lanes. A final therefore has eight competitors in lanes two to nine of a ten-lane pool.

Who was India's first Asian Games gold medallist in swimming?

Sachin Nag, who won the 100 metre freestyle at the first Asian Games held in Delhi in 1951. He is remembered as one of the gold medallists of India's very first Asian Games campaign.

Is rowing an aquatic sport?

Not in the technical sense used by exams. World Aquatics governs only swimming, diving, water polo, artistic swimming, open water swimming and high diving. Rowing has its own world body, World Rowing, and canoeing and kayaking have the International Canoe Federation.

What is the eggbeater kick?

An alternating circular movement of the legs that lets a water polo player stay high in the water with both hands free to pass, catch or shoot. It is also used by artistic swimmers, who may not touch the bottom of the pool.
