Swimming is a sport that involves moving through water using the arms and legs. There are four competitive strokes: freestyle, backstroke, breaststroke, and butterfly. Freestyle allows any stroke, backstroke is done on the back, breaststroke keeps the torso from rotating, and butterfly uses a symmetrical arm motion with a dolphin kick. Individual medleys involve swimming each of the four strokes for one quarter of the race in a set order, while relay races involve teams of four swimmers each swimming one stroke. Officials such as referees, starters, and judges monitor rules compliance and times.

TYPES OF STROKES
* FREESTYLE
* BREAST STROKE
* BACKSTROKE
* BUTTERFLY

6. FREESTYLE
*Freestyle swimming implies the freedom to choose any stroke
style for competitive swimming. This style is generally the
fastest.

7. BACKSTROKE
is one of the four swimming styles used in competitive events
regulated by FINA, and the only one of these styles swum on the back.
This swimming style has the advantage of easy breathing, but the
disadvantage of swimmers not being able to see where they are going.

8. BREASTSTROKE
is a swimming style in which the swimmer is on their chest and
the torso does not rotate. It is the most popular recreational style due to
the swimmer's head being out of the water a large portion of the time,
and that it can be swum comfortably at slow speeds.

9. BUTTERFLY
is a swimming stroke swum on the chest, with both arms moving
symmetrically, accompanied by the butterfly kick (also known as the
"dolphin kick").

10. Individual medley consists of a
single swimmer swimming
equal distances of four
different strokes within one
race.

11.  Individual medley consists of four strokes.
The swimmer will swim one quarter of the
race in each style, in a certain order. The
strokes are swum in this order:
 Butterfly
 Backstroke
 Breaststroke
 Freestyle (this can be any stroke except the
butterfly, backstroke, or breaststroke; most
swimmers use the front crawl)

12. Medley relay consists of four
different swimmers in
one relay race, each
swimming one of the four
strokes.

13. Medley relay is swum by four different swimmers,
each swimming one of the four strokes.
 The order of the strokes is as follows:
 Backstroke
 Breaststroke
 Butterfly
 Freestyle the only limitation being that none
of backstroke, breaststroke, or butterfly
stroke may be used for this leg. Most
swimmers use the front crawl.

assembles swimmers prior to each event, and is
responsible for organizing ("seeding")
swimmers into heats based on their times.

18. Each timekeeper takes the time of the
swimmers in the lane assigned to
him/her.

19. Each inspector of turns ensures that
swimmers comply with the relevant rules
for turning as well as the relevant rules
for start and finish of the race.

20. They follow the swimmers during their swim back and

make sure the swimmers finish in accordance
with the rules (two hands simultaneously for
breaststroke and butterfly, on the back for
backstroke, etc.)
