The "AMSSEFCSL" standard is very popular internationally. Here are the 9 major elements of the "AMSSEFCSL" standard:
Too heavy a racket will make the player slow in swinging, and a too light tempo will not be easy to cope with a strong shot and easy to remake.
Normal selection: Generally speaking, the range of application for young men is 320-330g, for middle-aged and older women, the racket is between 300-320g, and the range for young women is 280-300g.
M——measure (grip size)
As with weight, the size of the grip should be comfortable.
Normal selection: The average male player is suitable for 4 3/8. If the ability allows, it can also be used for larger ones such as 4 1/2; for women, 4 1/4—4 3/8.
S——skin (grip outer skin)
The outer skin on the grip is the part of the racket that comes into contact with the human body. When the skin is not good, the tempo will not catch well. In this case, even if you have a good racket and no good ball skills, you can't play it.
Normal selection: the grip skin needs to be noticed and replaced frequently, which is a good way to keep the grip outer skin in the best condition.
S——sweet spot (sweet spot of the face)
Deviate from the center of the racket and click on the ball. You can also hit the area where the ball is shot. English is called sweet spot (Chinese translation is "dessert" or "sweet spot"). Normal selection: the racket of the big shot is easy to learn, and it can hit the ball slightly from the center. The disadvantage is the lack of speed and poor control. It is suitable for women, beginners and older people. It is suitable to use about 110-115 square inches. . The small face is suitable for middle and senior players. It is characterized by fast ball speed and good control, but the sweet spot is small.
E——equipoise (balance point)
The balance point is related to the weight of the racket surface. Its central topic is the problem of "head weight" or "head light". This is also a topic that is "suitable for people."
Normal choice: the first weight is suitable for long shots, the bottom line is the right to hit the ball; the head light is suitable for tennis interception, and the players with both hands are often used.
The shape of each face has its own unique design concept, and the position of the sweet spot is different. Generally speaking, the shape of the face is mainly elliptical or egg-shaped, and the sweet spot of the oval face is at the center of the face, and the sweet spot of the egg-shaped face is in the center of the face after the face, the distance handshake Closer. Those who are better at steadily shooting can use the former, and vice versa.
Normal selection: This can be seen from the tempo profile or tag.
In terms of the construction of the tennis racket, the entire racket will have different hardness. Of course, those who have a large swing and strong strength are suitable for a tempo with a small hardness. (If a person with a large swing and a large strength uses a racket with a large hardness, the handle of the racket, the surface of the racket, and the frame of the racket are all Easy to damage).
Normal selection: There will also be a display in the tag, most of which is represented by a number. The larger the number, the smaller the hardness.
S - the number of pounds in the scales
The higher the pound size of the racket, the lower the elasticity, but the player with fast swing speed can get better ball control effect. The low number of pounds will produce the spring bed effect and increase the rebound force, and the relative ball control will be reduced.
Normal selection: The most commonly used pounds for tennis rackets are between 55 and 60 pounds. Professional players often wear them. ("Wearing" is a professional player who asks the manufacturer to wear a thicker cable when producing a racket. Because the cable is thicker, The pounds are larger) to around 70 pounds. L——linear (line selection)
The mainstream of the tennis line is the nylon thread. This kind of thread is popular because it is not afraid of moisture, abrasion resistance, mass production and reasonable price. However, the nylon thread also has disadvantages, that is, the pound size changes due to easy slack.
Normal selection: The line that is both durable and good to play is too small, because the line is thicker and more durable, and the finer the better, so the person who will be disconnected in three or two days is best to wear a diameter of 1.35mm to 1.45mm. The line, but the thick line feels not good; and the thin line is generally between 1.20mm and 1.30mm, the ball is sharper and the elasticity is better.
