If you are a lady, or an elderly person, or a teenager, you should never use a racket over 320g. Too heavy a racket will slow you down when you swing, and the more serious consequence is that you will get tennis elbow one day. On the other hand, you have good strength and quality, but you use a very light racket. In a fierce confrontation, you are likely to be defeated by a powerful ball.
So, what is the most correct concept to choose the weight of the racket? Remember this principle: you should choose the heaviest racket that is comfortable within your arm strength. This requires you to find several rackets with different weights to test before buying them to determine the most suitable weight.
Generally speaking, the racket string used by young and strong boys can weigh more than 320 grams, which is suitable for middle-aged and elderly people with poor strength and between 280 and 320 grams. It is best not to exceed 300 grams for ladies.
If you already have a racket, but it is too light, you can try sticking 1 g of lead on both sides of the racket frame, which is not enough. This kind of lead can be found in some special counters selling tennis supplies. This magical little lead block will surprise you.
Front dimension
There are different sizes of racket faces sold in the market, which can be basically divided into five types: small racket face, medium racket face, large racket face and super-large racket face.
The racket face is designed for people who have a strong desire to attack. The racket face of this kind of ball is 90 or 85 square inches, the sweet area is very small, and the ball is particularly hard. Because tennis rackets were all made of wood nearly twenty years ago, this material decided that the size of the racket face could not be very large, so some nostalgic people still like to use rackets with small racket faces.
Professional players like to use a 95-square-inch racket face. This kind of racket is not only aggressive, but also dull when hitting the ball because of its small sweet area, which can maximize the speed and accuracy of professional players. Therefore, amateur players with higher level prefer this kind of racket.
A racket with a racket face of 95- 100 square inch belongs to a large racket face. This racket made of high-tech new materials increases the area of the sweet zone without weakening its strength, so that it can still be uncontrolled in high-speed confrontation. Especially suitable for professional and amateur players with good control skills, quick response and dexterity.
The best horror racket sold in the market is 100- 1 15 square inch racket, especially 1 10 racket is the most popular. This kind of racket has a large sweet area and good elasticity. Ordinary people feel good when using it, and beginners, women, the elderly and skilled people can use it, so it has the widest application range. Many stable professional players also use this racket.
A racquet face with an area greater than 1 15 square inch is called a super racquet face. At present, the largest racquet surface is close to 140 square inch, which is simply a fishing net. You can hit the ball easily by raising your hand. Needless to say, this racket is specially prepared for the elderly, whose legs and feet are not very flexible, their swing is short and their strength is poor, so it will naturally be easier to use this racket.
Racket material
At present, carbon fiber rackets account for the vast majority in the market. Although advertisements are constantly promoting the "titanium series" rackets, only a small amount of titanium materials are added to the rackets. Just like Kefle materials were added to all-carbon fiber rackets a few years ago, the new slogan of the manufacturer is "We used aerospace materials". There are some rackets with boron or glass fiber added, but no matter what they are added, they are only a few ingredients. For a considerable period of time, carbon fiber made it impossible for the racket to have a greater change in material.
Adding glass fiber: low cost, low hardness and weight;
Boron addition: l hardness ↑, price ↑;
Kefle: toughness ↑, price ↑;
Titanium alloy: weight ↓, hardness ↑;
Plus the latest ultra-hard carbon fiber: the weight is left, the empty shot only weighs 220 grams, the swing speed is faster, the internet is more comfortable, and the price is high.

When purchasing rackets, we should first understand whether there is a "double complementary" system in the design of materials and shock absorption performance. Fans and young players who are new to tennis should choose rackets with moderate hardness and shockproof design.
Product name hardness elasticity adaptation
Graphite is hard, usually of medium strength.
Enamel is very hard and strong.
Type of boron extremely hard difference technology
Glass fiber is not hard, it is better to be comprehensive.
Hard, Medium and Full Sizes of Titanium Alloys
It should be noted that the hardness of the material is the goal of making a racket. However, only a racket with hard material, moderate swimming form and well-designed shock absorption system is a successful racket to adapt to the development of tennis. If it is a racket with weak shock absorption ability, a shock absorber can also be installed at the lower end of the racket face.
Is titanium good or not?
Of course, titanium molecules are smaller than other substances. It can fully fill the gap in the racket, minimize the air in the racket, and make the racket firm and long in service life. But there is another problem here: at present, various brands on the market have different treatment methods and different effects. There are two common types: the first is to make titanium powder from titanium powder and immerse it in carbon fiber to obtain the above benefits. The second is to use titanium rings to make titanium into fibers, and then mix them with other substances to weave them into a piece and put them on the racket. Because the racket is composed of two layers of substances, the two layers of substances may loosen or even crack after playing for a long time, which is not helpful to the durability of the racket. In this shop, due to my limited position, I can't tell you which brand of titanium powder and titanium ring are. If you really want to buy a titanium racket, you'd better ask the salesman or supplier. The racket with titanium is "deliberately" lightened and strengthened in weight and elasticity. Suitable for beginners and people with weak constitution. However, this kind of "deliberate" makes the existence value of the titanium racket questioned, and whether it is worth it or not is up to consumers to decide.
In fact, the tennis racket has developed from the original wooden racket, stainless steel and aluminum alloy to the present carbon fiber, which can be regarded as the stage of finding the best material, and tennis lovers can use it with peace of mind. In order to develop properly, it is enough to strengthen the control of carbon precision, hardness and elasticity.
Racket shape
Our most common racket face is oval, but also slightly square and the latest fan shape.
Each racket face has its own sweet zone design, and the size and position of the sweet zone of different brands of rackets are different. Generally speaking, the shape of the sweet area is similar to that of the racket face. When buying a racket, you must pay attention to the instructions on the tag attached to the racket, and make clear the location, shape and size of the sweet spot, so that you should try to hit the sweet spot when hitting the ball, otherwise you will complain that the racket is not easy to use.
The thickness of the racket also affects the performance of the racket. The thickness of the racket is between 22 and 22-34 mm, and the thicker the racket, the greater the hardness and the stronger the explosive force. The ball hit is powerful, but it is poorly controlled and easy to go out of bounds. If you have enough arm strength, you'd better use a soft thin racket. In addition, the thickness of some rackets is different, such as making the head of the racket thicker to increase the weight of the bottom line to the racket; Thickening the neck of the racket is to increase the stability of the racket at the moment of hitting the ball.
Racket balance point
What is the balance point of the racket? Ask those who are swinging vigorously on the court. I'm afraid more than half will shake their heads at you.
First, you measure your racket, which is the balance point of 1/2. Then, put the racket horizontally on the back of the chair, and the back of the chair is facing the balance point. At this time, the racket hangs down in the direction of the racket head, indicating that the racket head is heavy, and the racket hangs down in the direction of the racket handle, indicating that the racket head is light. If the racket can keep level, it means balance.
The standard length of the racket is 27 inches, and the center point should be 13.5 inches. If the balance point of the racket is between the center point and the neck frame, it is called (head weight), and if the balance point is between the center point and the grip, it is called (head weight). Generally speaking, the balance point is measured upward from the bottom of the racket in centimeters or inches.
The heavy racket is suitable for baseline play, which is convenient for singles; The light header is suitable for volley in front of the net, which is often used by tennis players and doubles players. All-around players with both offensive and defensive skills generally use more balanced rackets.
After understanding the balance of your racket, if you find that your racket doesn't match the style of the ball, you can still adjust it with the little lead mentioned above; Lead on both sides of the racket frame will make the racket head heavier. Add lead to the handle or the racket head, and the racket head will become lighter.
Handle size
When I play ball, I often hear people complain that my hands are weak and I can't hold the racket. Then his racket is either too heavy or the grip is too thick. When you play ball, the only contact point between you and the racket is the grip. What if this place is not suitable? Too thick grip will not only make people tired, but also make the ball and volley ball difficult to handle; Similarly, too thin grip is not desirable, which will make your grip not tight, and it is easy to loose when playing hard ball, which will lead to instability of the racket.
What size grip is best for you? That depends on the size of your palm. Pay attention to the label on the racket. Ordinary men generally choose the 43/8 grip, and those with big hands use the 4 1/2 grip. Ordinary women generally choose between 4 1/4-4 3/8, and those with extremely small hands use 4 1/8.
But I suggest you choose a slightly thinner grip, because the grip of the racket-commonly known as the winding handle-needs to be replaced frequently. After you buy a new racket, you'd better add a thin winding handle to it, which not only protects the grip of the racket itself, but also updates the thin winding handle in time.
If the thickness of the racket you have used is not suitable, it is easier to make it thinner and add a thin winding handle. If it is thicker, you have to peel off the thicker layer of the racket itself and replace it with a thin one. If it is too thick, it will not be easy.
With the above knowledge, choose a tennis racket that suits you, and you will find that your skills have advanced by leaps and bounds overnight!
