AN INTRODUCTION TO BADMINTON

Presented byJERRYLYN L. CLARITO

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.

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.

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

Sport Overview

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

and decelerate

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..

• 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.

• 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.

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.

• 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").

– 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.

– 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.

BADMINTON 14

StrategiesDoubles

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

SinglesThe 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

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

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

Techniques

• Forehands• Backhands• Smash• Lob• Push• Drop-shot• Drive• Net-shots• Clear shot• Others

Techniques – Forehand grip / backhand grip

Techniques - Lob

Techniques - Smash

The smash is an aggressive overhead stroke, which if used at the right moment, instantly weakens an opponent´s.

Techniques – Net Drop

These are the blows played close and very close the net.

Techniques - Drive

Techniques – Drop Shot• Set up and back-swing as you would for an overhead clear.• Turning your non racquet shoulder to face your target. • Hold your racket arm high with the racket's head behind you, at about shoulder height. • Position yourself behind and beneath the shuttle.

Techniques – Clear Shots

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.

• 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!

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):

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!
