2. What is “badminton”
Badminton is a racquet sport played by either two
opposing players (singles) or two opposing pairs
(doubles), who take positions on opposite halves of
a rectangular court that is divided by a net. Players
score points by striking a shuttlecock with their
racquet so that it passes over the net and lands in
their opponents' half of the court.

3. WHAT??
Badminton is a racquet sport played by either
two opposing players (singles) or two opposing
pairs (doubles),
 Players take positions on opposite halves of a
rectangular court that is divided by a net.

4. HISTORY OF BADMINTON
• WHEN??
 Badminton dates back to ancient Greece and Egypt
 In Japan, the related game Hanetsuki was played as early as the 16th
century
 In the west, badminton came from a game called battledore and
shuttlecock, in which two or more players keep a feathered shuttlecock in
the air with small racquets
 The game was called "Poona" in India during the 18th century
 The new sport was definitively launched in 1873 at the Badminton House,
Gloucestershire
 The game was referred to as "The Game of Badminton," and, the game's
official name became Badminton
 The Badminton World Federation (BWF) was established in 1934 with
Canada, Denmark, England, France, the Netherlands, Ireland, New
Zealand, Scotland, and Wales as its founding members. India joined as an
affiliate in 1936

5. Sport Overview

6. Badminton is a physically demanding sport,
requiring:
– strength
– endurance
– muscular power
– agility
– speed endurance
– anaerobic power
– capacity to rapidly accelerate
and decelerate

7. Equipment • Racquets
– Badminton racquets are lightweight, with top
quality racquets weighing between 70 and
95 grams (2.4 to 3.3 ounces) not including
grip or strings .They are composed of many
different materials ranging from carbon fibre
composite (graphite reinforced plastic) to
solid steel, which may be augmented by a
variety of materials. Carbon fibre has an
excellent strength to weight ratio, is stiff, and
gives excellent kinetic energy transfer. Before
the adoption of carbon fibre composite,
racquets were made of light metals such as
aluminium. Earlier still, racquets were made
of wood. Cheap racquets are still often made
of metals such as steel, but wooden racquets
are no longer manufactured for the ordinary
market, because of their excessive mass and
cost. Nowadays,nanomaterials such
as fullerene and carbon nanotubes are added
to rackets giving them greater durability..

8. • Shuttlecock
– The shuttlecock (or shuttle) is a feathered projectile
whose unique aerodynamic properties cause it to fly
differently than the balls used in most racquet sports;
in particular, the feathers create much higher drag,
causing the shuttlecock to decelerate more rapidly
than a ball. Shuttlecocks have a much higher top
speed, when compared to other racquet sports. A
shuttlecock (often abbreviated to shuttle; also called
a birdie) is a high-drag projectile, with an open conical
shape: the cone is formed from sixteen
overlapping feathers embedded into a rounded cork
base. The cork is covered with thin leather or
synthetic material. Synthetic shuttles are often used
by recreational players to reduce their costs as
feathered shuttles break easily. These nylon shuttles
may be constructed with either natural cork or
synthetic foam base, and a plastic skirt.

9. • Shoes
– Badminton shoes are lightweight with soles of rubber or similar high-grip, non-marking
materials. Compared to running shoes, badminton shoes have little lateral support. High levels
of lateral support are useful for activities where lateral motion is undesirable and unexpected.
Badminton, however, requires powerful lateral movements. A highly built-up lateral support
will not be able to protect the foot in badminton; instead, it will encourage catastrophic
collapse at the point where the shoe's support fails, and the player's ankles are not ready for
the sudden loading, which can cause sprains.

10. Rules
• Playing court dimensions
– The court is rectangular and divided into halves by a net. Courts are usually marked for both
singles and doubles play, although badminton rules permit a court to be marked for singles
only. The doubles court is wider than the singles court, but both are of same length. The
exception, which often causes confusion to newer players, is that the doubles court has a
shorter serve-length dimension. The full width of the court is 6.1 metres (20 ft), and in
singles this width is reduced to 5.18 metres (17 ft). The full length of the court is
13.4 metres (44 ft). The service courts are marked by a centre line dividing the width of
the court, by a short service line at a distance of 1.98 metres (6 ft 6 inch) from the net,
and by the outer side and back boundaries. In doubles, the service court is also marked
by a long service line, which is 0.76 metres (2 ft 6 inch) from the back boundary. The net
is 1.55 metres (5 ft 1 inch) high at the edges and 1.524 metres (5 ft) high in the centre.
The net posts are placed over the doubles sidelines, even when singles is played.

11. • Scoring system and services
– Basic
• Each game is played to 21 points, with players scoring a point whenever they win a rally
regardless of whether they served(this differs from the old system where players could only
win a point on their serve and each game was played to 15 points). A match is the best of
three games. At the start of the rally, the server and receiver stand in diagonally
opposite service courts (see court dimensions). The server hits the shuttlecock so that it
would land in the receiver's service court. This is similar to tennis, except that a badminton
serve must be hit below waist height and with the racquet shaft pointing downwards, the
shuttlecock is not allowed to bounce and in badminton, the players stand inside their service
courts unlike tennis. When the serving side loses a rally, the serve immediately passes to
their opponent(s) (this differs from the old system where sometimes the serve passes to the
doubles partner for what is known as a "second serve").

12. – Details
• When the server serves, the shuttlecock must pass over the short service line on the opponents' court or it will
count as a fault. If the score reaches 20-all, then the game continues until one side gains a two point lead (such
as 24–22), up to a maximum of 30 points (30–29 is a winning score). At the start of a match, the shuttlecock is
cast and the side towards which the shuttlecock is pointing serves first. Alternatively, a coin may be tossed, with
the winners choosing whether to serve or receive first, or choosing which end of the court to occupy, and their
opponents making the leftover the remaining choice. In subsequent games, the winners of the previous game
serve first. Matches are best out of three: a player or pair must win two games (of 21 points each) to win the
match. For the first rally of any doubles game, the serving pair may decide who serves and the receiving pair
may decide who receives. The players change ends at the start of the second game; if the match reaches a
third game, they change ends both at the start of the game and when the leading player's or pair's score
reaches 11 points.

13. – Lets
• If a let is called, the rally is stopped and replayed with no change to the score. Lets may occur
because of some unexpected disturbance such as a shuttlecock landing on court (having been hit
there by players on an adjacent court) or in small halls the shuttle may touch an overhead rail which
can be classed as a let. If the receiver is not ready when the service is delivered, a let shall be
called; yet, if the receiver attempts to return the shuttlecock, he shall be judged to have been ready.

14. BADMINTON 14
Strategies
Doubles
Both pairs will try to gain and maintain the attack, hitting
downwards as much as possible
 Whenever possible, a pair will adopt an ideal attacking formation
with one player hitting down from the rear-court, and his partner in
the midcourt intercepting all smash returns except the lift
Singles
The singles court is narrower than the doubles court, but the
same length
Since one person needs to cover the entire court, singles tactics
are based on forcing the opponent to move as much as possible;
this means that singles strokes are normally directed to the corners
of the court

15. BADMINTON 15
Mixed doubles
In mixed doubles, both pairs try to maintain
an attacking formation with the woman at the
front and the man at the back
This is because the male players are
substantially stronger, and can therefore
produce more powerful smashes

16. Did You Know??
 Men's doubles player Fu Haifeng of China set the official world smash record of 332
km/h (206 mph) on June 3, 2005 in the Sudirman Cup
The fastest smash recorded in the singles competition is 305 km/h (189 mph) by Taufik
Hidayat of Indonesia
 The shuttlecock is strongly affected by wind, hence all the competitive badminton is
played indoors
 The shuttlecock is very aerodynamically stable. Regardless of initial orientation, the
shuttlecock always fly cork-first and remains in the cork-first orientation

37. Curiosities of Badminton
• Better
– The best countries in the world in badminton are Indonesia
and China, the two together conquered 70% of all of the
events of IBF.
– Other dominant countries in this sport are: Malaysia, Korea
and Denmark.
• Bruises
– In spite of being an inoffensive sport, badminton when
played by professionals, it can, due to speed of the
shuttlecock, offer some danger for the players' eyes. It is
advisable to professionals to use protective glasses.

38. • Popularity
– The popularity of badminton was proven during the premiere as an
Olympic sport in Barcelona in 1992. Around 1.1 billion people
watched the competitions on television.
– Now, more than 130 countries are members of the International
Federation of Badminton.
• Speed
– Badminton is the fastest racket sport of the world demanding fast
reflexes and great physical conditioning. During a professional
match the shuttlecock can reach the speed of ± 260km/h!

39. Tennis vs. Badminton
The statistics don't lie, see this comparison among a tennis game (Boris Becker vs.
Kevin Curren for All England Championship) and a badminton game (Han Jian vs
Morten Frost for the World Badminton Championship):
Tennis Badminton Difference
Time of Game
3 hours and 18
minutes
1 hour and 16
minutes 2 hours
Ball / shuttlecock in
game 18 minutes 37 minutes 49%
Number of Blows 1004 1972 51%
Covered distance 3,2 Km 6,4 Km 50%
Note : That the badminton players compete only half of the tennis players'
time and even so, they run twice as much and they almost hit the double
as many of times!
