The first reason that affects the feel of a badminton racket is the pressure of the racket, which is the tightness of the badminton strings. Generally, 1 pound is used as the unit. Different machines have different tightness. Based on YY (abbreviation of Japanese YONEX) machines, 18 to 21 pounds is a kind of feel, 22 to 24 pounds is a kind of feel, 25 to 27 pounds is a kind of feel, and 28 to 30 pounds or more is a kind of feel. The lower the racquet pressure, the more obvious the slingshot effect will be (too low will not work), and you can easily pull back the court. Due to the long control time of the ball, the arc and landing point of the ball are better controlled, and the sweet spot is large (the sweet spot is the best hitting area on the racket surface. When the hitting point is in the sweet spot, it can give you enough impact The ball has little power, control, and vibration, and you will feel very comfortable. The size of the sweet spot is very important to players. It makes it easier for players to hit high-quality balls. It also has good tolerance for movements. Very suitable for pull-up play. But when pressing the ball down (most obvious for sudden smashes), if the movement is relatively small, it will be difficult for the ball to be pressed down and run straight to the baseline. Due to the slow take-off speed, the ball seems to stick to the racket, making it difficult to control the landing point. If you want to hit the ball closer to the net and deeper into the net, you have to lower the net. Therefore, people who use a lot of pressing techniques generally prefer higher shooting pressures. The advantages of high pressure are sharp ball control, fast release speed, and good placement of downward pressure. A small movement can hit the ball at a large angle, at the cost of strength and ball control. High pressure is just suitable for the fast characteristics of current professional badminton, so the average weight of professional players regardless of men and women is generally 30 pounds, and doubles is higher. Like Zhang Jun, it is 35 pounds. Most people should not use more than 27 pounds of pressure. Even if the action is correct, it will be very tiring to grab the backcourt well. There is no speed in killing the ball, and his hand becomes soft after a few hits. What's more, there are basically no amateurs who can grab points by exerting force in front of the body. And it’s good if a good badminton racket can always bear 26 pounds. The high-voltage line breaks quickly. The last few times the high-voltage frame hit the ball, it was basically broken. The most common method of pulling the thread through to the bottom is called the two-point threading method. It is easy to draw the thread with a hook and break it quickly. And it’s easy to lose weight and route cables. YY uses the 4-point threading method, which has 4 knots and is threaded separately horizontally and vertically. Without a hook, the life of the line is significantly longer. And it’s not easy to lose weight and route cables. The horizontal line pressure is 10 points higher than the vertical line, usually two pounds, starting from the 6th line. The vertical line is 5.5 meters and the horizontal line is 4.5 meters.

The second reason that affects the feel of a badminton racket is the hardness of the middle tube of the racket. A soft racket has the same effect as a low racket pressure, but has less impact on smashing the ball. The hard pole has a better press-down point and is faster to release the shot, but it is more laborious. It is suitable for professionals and players who use more press-downs. Today's rackets are much softer than before, and soft racket shafts are the development trend. The racket shaft and frame of good rackets are made separately, while low-end rackets have an integrated frame and racket, with a hook on the racket shaft forming the racket frame. Whether it is made of high-hard carbon, ordinary carbon, unidirectionally arranged "wood grain carbon" or vertically and horizontally arranged braided carbon, the racket shaft can be soft or hard. In addition to longitudinal fibers (which make the racket elastic and powerful), there are also horizontally wrapped fibers (which reduce the torque of the racket, improve the stability of the racket surface when hitting the ball, and improve the control ability of the racket). They are generally not in one layer. In order to reduce the torque of the racket, some add TI (titanium) net (such as Japan's GOSEN5000TI) or TI line (such as all YY rods plus titanium racket) to the racket shaft. The thickness of the racket shaft is divided into different thicknesses. It is said that the thin shaft accelerates faster. I don't think there is any difference. When choosing a shot, the closer the bending point of the shot is to the handle, the better.

The third reason that affects the feel of a badminton racket is the length of the racket. The standard length of the racket is 665MM, and the length of the extended racket is generally 675MM, but the maximum length cannot exceed 680MM. Extended rackets include those with an extended shaft and those with an extended handle. Extending the racket shaft can take care of a wider range and increase the offensive power. This is the current development direction. All the rackets released by YY now are lengthened. However, the longer the racket arm, the longer the ball control will be affected. The main function of the racket handle is shock absorption. Its material is wood, so the racket handle is also called a wooden handle.

The quality is relatively good, and the harder wooden handle not only has better shock absorption effect, but also is not easy to break. Its circumference is G3 (circumference 89mm), G4 (circumference 86mm), G5 (circumference 83mm), and the handle and racket are The part connected to the rod is the handle taper, which is used to prevent the wooden handle from cracking. It is actually a plastic cap. In order to absorb shock, the handle cone is now thickened, hardened and shortened. As for the shock-absorbing pad, I think it’s a gimmick. I’ve never seen it used on YY and GOSEN’s top-end models. Open the bottom cover of the wooden handle, and you can see a hole in the wooden handle with glue inside, which is the counterweight (the hollow handle can effectively absorb shock, and this design has long been widely used in table tennis rackets). When it comes to counterweight, we have to talk about the balance point of the racket. Counting from the bottom of the handle to the head of the racket, the balance point of the racket is generally between 280MM and 300MM. The smaller the balance point value, the more flexible the beat will be. Suitable for control style. The larger the balance point value, the greater the power of hitting the ball. Powerful hitting can not only produce upward force, but also have a stable landing point that is easy to control. It’s best not to switch between long and short racquets. I always can’t hit the ball after using the longer one and then the shorter one.

The last thing is the racket frame, racket surface and weight. The cross-sectional shape of the racket frame was originally round (especially the part connected to the racket shaft). For example, the most common aluminum alloy racket is a pair of two. This design is no longer used in full-carbon rackets. Instead, there is a square box-shaped frame. It had much less torque, and later had a flat, wide, oval-shaped airfoil frame. It has less swing resistance than a box-shaped frame, but has greater torque than a box-shaped frame, so it is generally a structure with an upper wing and a lower box. YY's wavy grooves appeared for a while, but then YY stopped using them. The current racket surface shapes include the traditional oval racket surface and the most commonly used square head racket frame (the length of the racket head becomes square, which has 8 wire holes and is commonly known as "big square head", and has 6 wire holes and is commonly known as "small square head". ]). The advantage of the square head is that the sweet spot is large. The larger the square head, the more obvious it is, but it also increases the torque. In fact, the difference between the relatively low-pressure square-head racquets and the oval-shaped racquets is not very obvious. The medium-pressure square-head racquets are obviously easier to use than the oval-shaped racquets. At high pressure, the sweet spot of the square-head racquets becomes larger. But it's not as crisp as the oval type. Taking everything into account, square-head shooting works best and is the direction of development. The racket frame is also equipped with TI, which is said to reduce the vibration of the racket surface. Improve batting stability. The weight of badminton rackets is divided into 2U (90-94 grams), 3U (85-89 grams) and 4U (80-84 grams). The light one is more flexible, while the heavy one is more powerful in attack. For the same balance point, choose the heavy one, at least the material is strong enough.

When purchasing a badminton racket: first look at the brand. Most badminton rackets are made of gold and jade on the outside, but are broken inside. It can be seen from the X-ray (see picture). YY deserves to be the world's number one brand, from the cheapest CAB-010 (generally 180-200 yuan) to the best CP version (China National Team version, before 2000, the Chinese National Team version was usually the CN version) MP100, carbon They are all so even, there is no counterweight in the frame, the connectors are at the bottom, and they all have patented TI connectors. Therefore, no matter whether it is soft or hard, expensive or cheap, the shooting torque of YY is very small. YY's rackets have relatively low standard shooting pressures. In fact, high pressure is no problem. The first-generation all-carbon racket (not high-hard carbon) CAB-20 2U has no problem pulling 28 pounds. The reason why the racket is broken is usually because there is a problem with the fixing clip of the string drawing machine, or because the string drawing technique is not good. So it’s best to go to YY which specializes in pulling strings. In fact, it saves money. YY is a brand that has been around since the 1940s. It has old and new brands. Nowadays, they are generally divided into CAB series. The oval racket type has good workmanship and high cost performance. ISO series, square head type, without titanium, there are several high-quality models. The titanium series has TI added to the 3 o'clock and 9 o'clock positions of the ISO frame (both sides of the frame). MP series, the racket frame is equipped with MP wavy groove technology. In the AT series, the upper part of the racket head is made of titanium armor alloy. NS series, nano shot. . Japan's GOSEN is the second-largest brand in the world and is the designated racket for the Malaysian national badminton team. Its reputation is second only to YONEX. It has famous players such as Wang Youfu, Zhong Tengfu, Wei Renfang, Wang Lianxiang, and Wang Chen. The racket has high technological content and has unique ROOTS (double T-shaped joint), GAVUN SHAFT and other patents. Judging from the X-ray of its representative model 5000TI, the workmanship is better than that of YY.

However, its shortcomings are that some factory products have raised doubts about its Japanese origin. The frame is relatively soft, the paint is easy to peel off, it is relatively light, and the price is relatively high. But it is indeed a classic shot. 5000TI is divided into three versions: red, blue and purple. The red version is a soft version, the blue version is a hard version (actually quite soft), and the purple version is unknown. KENNEX in Taiwan was the first company to produce carbon rackets. It has 85 patents on the production of carbon rackets. It once produced one of the four rackets in the world. It was a diversified enterprise that later collapsed due to investment mistakes. The old Kenneth 787 is one of the most famous classic badminton rackets. It is chosen by many professionals. Its appearance and performance are very similar to Yonex's CAB-20. There are several other good badminton rackets that can be said to be the same. There is not much difference in quality between YONEX, but due to YONEX's excellent marketing, KENNX has basically been suppressed, and now KENNX is no longer good. But a classic is always a classic. KINETIC ULX (100 ultra-high coefficient carbon fiber material and KENNEX's unique "Kinetic system technology" 85-90 grams standard ISO ultra-hard) and TITANIUMULX (70 ultra-high coefficient carbon fiber material, 30 glass fiber titanium mesh Material. 90-95g standard ISO is very hard) It is a relatively technical and distinctive racket. But it is not as famous as the old 787. There are many other famous brands such as the British Carlton badminton racket and the German OLIVER. However, you cannot buy genuine products in China. They are all domestic imitations (the agent sued me). So there is no reason not to buy YY if it costs more than 200 yuan.

The second is to pick shots. No matter how advanced the camera is, there will still be problems. First, like a carpenter, look at the four directions of the wooden handle to see whether the racket shaft and the wooden handle are in a straight line, and whether the ridges of the racket frame and the wooden handle are twisted. Since non-degreased and pressed wood will deform when it gets wet or dry, crooked handles are common. The second is to reshoot and remove things like hanging tags. Hold the balance point or lower position of the racket with your hand and quickly rotate the racket handle. If the racket does not shake at all, it means that the racket frame and racket handle are correct, the racket frame is not deformed, and the racket shaft is straight. The third is to check whether the distance between the threading holes is the same, and whether there are any crooked holes, especially near the racket head. First, check whether the threading mark is on the extension line of the racket shaft (the 787 has two threading marks that are asymmetrical), and then look at them in turn. The distance between the threading holes on both sides of it. If the threading hole is drilled crookedly and the string is asymmetrically strung, the racket will be deformed, especially when the force is uneven under high pressure, the frame will easily break. The fourth is to twist the racket shaft and bend it again to feel if there is any looseness, and listen for the sounds of seams cracking and fibers breaking. The fifth is to grab both sides of the racket frame and push it toward the middle to feel the hardness of the racket frame and listen for the sound of fiber breakage. The last thing is to see how the paint goes. When the string is on well and the racket shakes, it means that the string is not on the string properly and the racket frame is deformed. It’s up to you what to do.
