    Brief Analysis concerning the relationship between Designing Racket with Various Badminton Shots



    The racket is the only medium between the player and the shuttlecock; in the process of a player hitting the shuttlecock, the racket is the only thing that comes into contact with it; every aspect of the structural design of a racket will affect the quality of return shots. Today, let’s talk about the effect of various shots on racket design.

    Badminton shots can be divided into several dozen types according to front face/back face, straight line, opposite angle , the racket face change, horizontal angle difference, shuttlecock landing point and other factors.

    Below, we will introduce the nine main shots : clear,slow drop shot, drive,net shot, net lift,smash, cross-court net shot, passive shot and backstop.



    1. Clear





    The clear is the longest shot in terms of horizontal distance and quite a lot of power is used when this shot is played, which means the torque resistance of the racket must be increased, otherwise, the instant the shuttlecock is hit, the racket will not be able to bear the impact caused by the speed of the swing and will turn, with the result that the player cannot place the shuttlecock accurately.

    This means, for this shot, racket “power” and “stability” are the most important racket characteristics.



    2. Net Lift





    For the defensive net lift, height and depth are most important;a high quality net lift will make the shuttlecock climb quickly in the early stages of flight, then slow down at the high point and fall down.

    To make the shuttlecock climb quickly the speed the racket is swung has to increase in a short space of time and this makes racket speed the most important racket feature for net lifts.



    3. Net Shot





    The net shot, often used by attacking players, requires a really deft touch. The most important part of the net shot is the “rubbing ” movement; the racket travels only a short distance in the swing and impact is relatively small;

    the shot requires that the player has good feel so the racket needs to be “agile”.



    4. Slow Drop Shot





    Slow drop shots are a stern test of a racket’s stability. In the process of playing the slow drop shot, at the instant that the shuttlecock hits the face of the racket the direction of the swing has to be changed, causing the shuttlecock to quickly decelerate and drop at the front of the court because it is subject to component force in another direction.

    The racket hits the shuttlecock at a non-vertical angle, greatly increasing the chance that the face will turn!

    This means that racket stability is the main requirement for this shot.



    5. Smash





    The smash is the fastest, most aggressive and destructive badminton shot and requires quite a lot of racket swinging power, which means that the racket’s torque resistance must be increased.

    High speed hitting of the shuttlecock also causes substantial vibration; at this time the role played by the sweet spot is not just as the “effective hitting area,” it also “reduces the strength of the vibration caused by the impact of the shuttlecock.

    The most important racket features for the smash shot are power, stability and sweet spot.

    6. Drive





    The drive is an attacking shot. The drive is often a response to the opponent’s smash and has a counterattacking flavor; the distance and time the racket accelerates are also very short so, when designing a racket, racket speed must be considered.

    Also, to reduce the burden on the wrist caused by rapidly turning the racket and the impact of hitting the shuttlecock during fierce exchanges, the agility of the racket is also very important.



    7. Cross-Court Net Shot





    The cross-court net shot is a shot that requires a player to have excellent feel and is often used in a series of attacking shots or as a counter attack shot; delaying the time the shuttlecock is shot and disguising the striking movement can also make it hard for the opponent to start moving or keep their balance.

    This delicate shot, requiring rapid changes in the angle of the face and direction of swing, needs a racket that is agile.



    8. Backstop Shot





    The backstop is a relatively passive defensive shot and is often used in response to fast shots from the opponent when there is no time to take a proper swing; it uses the power of the incoming shot to send the shuttlecock in a flat trajectory over the net to the front of the court.

    The speed of the incoming has a large impact on the racket and, to allow the angle of the return to be precise, it is important that the racket has good torque resistance; the incoming shuttlecock is also travelling quickly so the player needs to also be able to turn the racket rapidly and smoothly.

    For the backstop shot, stability and agility are the two main characteristics required of a racket.



    9. Passive Shot





    The passive shot is a shot often used by control-type players. The landing spot of the shuttlecock and its speed aren’t most important, what is most important is making sure the shuttlecock flies low over the net.

    Because the shot is made from the back line more power is required than would be from in front of the net, so the torque resistance of the racket must be increased; the position of the shuttlecock is also below shoulder height or even below waste height and, when the shot is played the racket must be swung smoothly and with dexterity.

    “Stability” and “agility” are the main considerations with regards to racket characteristics.

    Victor Tips - Choosing the Right Racket for You




    【Q】I am a beginner and I am worried that, after only swinging a racket a few times in the shop, when I actually play with it I will find it doesn’t suit me.
    How do I choose a racket that suits me?


    【A】VICTOR recommends that, because when you begin to play you are technically immature in every respect, you should choose a racket with a shaft of medium stiffness or one that is slightly soft, and should avoid choosing excessively stiff or soft rackets.

    If you are an aggressive player who smashes a lot, after playing for a while you can change to a racket with a shaft that is quite stiff.

    If you are a skillful player who likes to use drop shots and has less power than the aggressive type of player, choosing a racket with a shaft that is quite soft will help raise your skill level.




    【Q】How can I find out the string tension that suits me best?
    Does the higher the tension mean the better I will play?


    【A】In general, beginners should use string tension of 18-22 pounds.

    Basically, the higher the tension the better a player is able to control the shuttlecock,

    however, the power required also increases, making greater demands in terms of wrist strength;

    the lower the tension is the greater the power of string rebound, however, the shuttlecock is harder to control.




    【Q】How are racket weight and balance point compared?


    【A】Weight and balance point are the two main factors that affect racket feel. If you choose a racket with weight and balance point that match , you will get used to using it more easily.

    (1) Weight:
    The label shows that the Victor 2U weighs 90.1-95g, the 3U 85.1-90 and the 4U 80.1-85g (this is the unstrung weight). Professionals have weight error of around ±0.5g

    (2) Balance point:
    The balance point of a racket is usually 295mm.

    How is the balance point measured?
    It’s simple, the index finger or a pen can be used to measure it. Place the racket across the index finger and move it side to side to find the balance point, then measure from the bottom end of the racket to the balance point to find the length of the balance point.

    Heavier rackets give more attacking power but are unwieldy, however, if the balance point is moved forward (towards the head), a “head-heavy” effect can be increased, achieving a relatively good balance between swing agility and attacking capability.




    【Q】What is the shaft principle? Why is the shaft so important?
    How large an effect does shaft stiffness and width have on a racket?

    【A】The shaft is the central nervous system of a racket and how good it is decides the stability and feel of a racket.


    (1) Shaft material:
    Most rackets are made of graphite and the better the quality of the material the stiffer the shaft will be and the longer its life.

    Victor’s top-end rackets are made of Ultra high modulus graphite, greatly increasing their lifespan

    (2) Shaft width
    Generally speaking, the thicker a shaft is, the greater the torque and the power of the return shot; thinner shafts are softer , however, generally speaking, the thickness of the shaft has a relatively small impact on a racket.

    (3) Shaft stiffness
    The average player cares about racket stiffness and this also a key factor affecting the shuttlecock strike.

    The stiffer a shaft is, the greater the striking power, however, the burden on the player’s arm is also increased.

    A shaft that is quite soft spreads power but, striking precisely is harder. Most professional players use rackets that have stiff-very stiff shafts because they have the arm strength to swing such a racket and can create relatively large striking power, however, the average player should take into account their own capability because stiffer is not necessarily better.
