BADMINTON & DISABLEDS

Two associations of El Salvador, the Badminton Association of Salamá and the school of special education and rehabilitation center (Edecri) , work together in badminton classes wich it's purpose is improve the motor ability of children with disabilities.

According to the coach of badminton and active promoter, Wiliam Cabrera, they believe that many disabled children can learn this sport. All young people interested in playing badminton and shown that they want do it, they can go at a school in the Association where this sport is will be taught them to the point that can. Also they can participate in the competitions of the category for special children.

Already satisfactory results in their behavior, according to the Director of the Edecri that they have been checked since. In addition to improving their sport abilities, they relate to more people  and companions.

STRENGHT IN BADMINTON

The low weight of modern badminton racquets and low inertia of the wheel mean that badminton has a relatively low demand for absolute force. However, the badminton players will benefit from increasing their speed strength.

To improve this strength we can do diferents exercices in:

Lower body:

Calf Raises                                                                                         Lunges

                                                         

Crunches                                                                                            Squat
                                                               

Deadlift

      

Upper body:

Barbell Wrist Extension                                                              Shoulder Rotation
                                                                    

Shoulder Press                                                                             Single Rows                                                   

MUSCLES USED IN BADMINTON

Badminton is almost all-body sport and the scapular region of the upper limb, upper arm, forearm, abdomen and back. But there are some muscles that play more important roles than others like triceps brachii for hit the shuttlecock.

How do our muscle groups move when...
... we attack at the net?

We first bend our elbow a suitable amount as we prepare to hit the shuttlecock. For this bending movement, the biceps brachii is the agonist muscle; the contraction of the biceps brachii pulls the forearm close to the body; the triceps brachii plays the role of antagonist muscle, adjusting the speed the elbow bends, the agonist muscle and antagonist muscles acting simultaneously to maintain balance.

Then, when we are taking an attacking opportunity, we will straighten the elbow to hit the shuttlecock powerfully. At this time, the triceps brachii is the agonist muscles, the contraction of the muscle taking the forearm far away from the body to complete the arm-straightening movement; the biceps brachii is the antagonist muscle, acting in unison with the agonist muscle. 

... when we jump up to deliver a smash?

When we squat, the tibialis anterior is the agonist. The contraction of the tibialis anterior, moves the front-side of the lower leg and tiptoes together, while at this time the gastrocnemius is the antagonist muscle, responsible for relaxing and supporting the tibialis anterior. Then, the gastrocnemius is the agonist muscle; its contraction moves the front of the lower leg and tiptoes apart, in doing so completing the jumping movement. 

STRENGTH`S INTRODUCTRION

In sport, the definition of strength is the ability to move or lift a maximum weight. The extent to which a maximum force can be exerted ,changes depending on training goals and how it is used in a study.

Types of strength:

Maximal Strength

Maximal strength is the amount of force that can be generated from one, all out effort, regardless of time or bodyweight.

Explosive Strength

Explosive strength is strength per unit of time. This type of time-specific force depends on the amount of force you can generate in the shortest amount of time. In terms of strength calculation, it means how fast your body can move from one point to another.

Strength Endurance

Strength endurance is the amount of force you can generate for an extended period of time. This is the ability to be as strong as possible, as long as possible. Two different forms of strength endurance are there; Dynamic and Static.

• Dynamic Strength - This type of endurance is normally related with repeated movements in which sizeable strain is recurring devoid of any disruption during each cycle of movement.

  

• Static Strength - This type of endurance implies isometric tension of varying magnitude and duration on the body. It can also imply to the strain in holding a certain posture. 

Speed Strength

Speed strength is defined as the ability to quickly execute an unloaded movement or a movement against a relatively small external resistance

Limit Strength

It is the amount of force that you can generate from one all-out effort. This is the actual foundation for all your other strength gains. Limit strength can be of three types:

• Eccentric limit strength is the amount of weight you can lower with control.

                                                     

• Concentric limit Strength is the amount of weight you can lift at once, if you put in all your efforts.

                                                     

• Isometric limit strength is the amount of weight you can hold up without losing control.

Stabilization Strength

Stabilization strength involves improving the stability and strength of body’s core. Without core strength, force production, force transference, and force reduction will not occur properly.

BADMINTON VS SQUASH

The objective of badminton and squash is different, in badminton you have to try to pass the shuttlecock above the network by tapping it with the racket to get falling on the floor of the opposite field whenever you get it, you score a point. However in squash, the players have to hit the ball against a front wall (also the ball may strike the side or back walls at any time), between two out lines, then the ball is allowed to bounce once on the floor before a player must return it, if the player don't return it, the player who has served will get a point. In both sports you can´t hit the shuttlecock or ball twice consecutive.



In badminton matches are disputed of three types: singles doubles, and mixed doubles. It is played in two fields of 13.30m x 5,18m separated by a network of 2.28m of height. The network cannot touch. While, in squash, there are two kind of matches: two players (singles) or four players (doubles). The squash court is 9.75m x 4,26m.

The serving and the scoring in squash are more simple than in badminton. The current official scoring system for squash is called point-a-rally scoring (PARS). In PARS, the winner of a rally always receives a point. Games are played to 11, players must win by two clear points. Competition matches are usually played to "best-of-five"

CREATE YOUR OWN BADMINTON RACKET

Hello everyone!  In this post, we are going to help create your own badminton racket "homemade", made with economic materials and easy to find in our day to day. Without further preambles, we started:

MATERIALS

•  
•  FLEXIBLE WOOD STICK 
•  WOOD STICK
•   DUCK TAPE
•  NYLON THREAD
• SANPAPER

INSTRUCTIONS

1. Find a stick that is roughly the same length and diameter as a regulation badminton racket. This will form the handle and shaft of your racket. 
2.  Find a flexible stick or tree branch that can be bent into a circle. This will form the head of your racket and will be used to return the shuttlecock. You need a stick that won't split or crack when you bend it.
3. Bend your stick into a full circle with your hands until each end meets the stick that you are using for your handle. Make it as symmetrical as possible. Use duct tape to attach the flexible stick to your handle. Use enough duct tape to ensure the racket holds together during a game of badminton.
4. Cut the nylon with scissors into strips slightly longer than the horizontal and vertical length of your racket head. Line up the nylon going vertically and horizontally across the racket head at approximately one cm intervals. Tie the nylon around the bendy stick of your racket head.
5. Wrap duct tape around the base of the stick used for your handle to improve your grip on the racket. Sand the head of the racket to remove any imperfections.

BADMINTON VS PADDLE

The objective of badminton and paddle is to pass the shuttlecock above the network by tapping it with the racket to get falling on the floor of the opposite field whenever you get it, you score a point. You can´t hit the shuttlecock or paddle ball twice consecutive or touch it with your body.

Matches are disputed of three types: singles doubles, and mixed doubles. It is played in two fields of 13.30m x 5,18m separated by a network of 2.28m of height. The network cannot touch. While, in paddle, the matches are disputes of two types: singles or doubles. The paddle court is 20m x 10m. In both sports, if the shuttlecock or the paddle ball falls on the ground outside the exterior lines of the field, or touch the roof or side walls, the last player commits a lack.

 In badminton, if the player has an even score of (0-2-4 - 6 points...) effected the throw-in from the right to the area diagonally. If the score is odd (1 3 5 7 points...) it gets out of the left side. All the kickoffs are made from the lower part of the body. Nevertheless, in paddle, the kickoffs are made from different places depending from the points (when you score one point you change the position) and it is carry on by the two or more players. Also, it’s made in diagonal.

Court	13.30m x 5.18m	10m x 20m
Net	2.284m high	0.85m high
Ball	4.75g	56.7g
Racquet	68cm long	45.5cm long

Regulation	3 sets 15 points each	3 set with 6 games and 4 points each game

BADMINTON´S CURIOSITIES

Speed: Badminton is racquet sport the world's fastest since the shuttlecock can reach the incredible speed of about 300 Kmph.

Physical condition: the high speed that takes the shuttlecock requires professional player to have great reflexes. But this is not all, a player must have, in addition, great physical condition through an average distance of 1, 5 Km.

Shuttlecock:: A shuttlecock weighs between 4.74 and 5.50 g. and is composed of 16 feathers.

The speed of the shuttlecock varies in different regions of the planet. Environmental factors such as humidity and temperature make the shuttlecock to fly faster or slow. If fold inwards, the shuttlecock will fly faster while doing outward, it will fly more slowly.

The greater shuttlecock of the world is located in the gardens of the Kansas City Museum. It is 48 times larger than normal!

Injuries: Badminton is a little dangerous sport. However players can suffer serious visual injuries because of the speed which takes the shuttlecock. In this sense, the use of protective goggles is recommended.

147 countries, including Spain, are members of the I.B.F. (International Badminton Federation).

Competitions: The "Thomas Cup" is the men's World Championship. It has been won only by 3 countries since it began in 1948: Malaysia, Indonesia and China.The "Uber Cup" is the women's .

  

The best countries: the best countries in the world in badminton are Indonesia and China. Indonesia is the first country in the ranking of the IBF and Indonesian players lead the world ranking in all categories.

BADMINTON VS TENNIS

The objective of Badminton is to pass the shuttlecock  above the network by tapping it with the racket to get falling on the floor of the opposite field whenever you get it, you notaries a point . You can´t hit the shuttlecock twice consecutive and touch it with your body. This is the same that in tennis but the only main difference is, instead of the shuttlecock, we use a tennis ball.

Matches are disputed of three types: singles, doubles, and mixed doubles .It is played in two fields of 13.30m x 5,18m separated by a network of 2.28m of height. The network can not touch. While, in tennis, the matches are disputes of two types: singles or doubles. The tennis court is 23,77m x 8,23m. In both sports, if the shuttlecock or the tennis ball  falls on the ground outside the exterior lines of the field, or touch the roof or side walls, the last player commits a fault.

In badminton, if the player has a even score  ( 0-2-4 - 6 points...)  effected the throw-in from the right to the area diagonally. If the score is odd (1 3 5 7 points...) hes/she serves of the left side. All the kickoffs, are made from the lower part of the body. Nevertheless, in tennis, the kickoffs are made from different places depending from the points (when you score one point you change the position) and it is carry on by the two or more players. Also, it’s made                                                            in diagonal.
