String durability
We usually hope that our tennis line is omnipotent, has a good shot, and is very durable. Unfortunately, there is always a dilemma between desire and reality. Usually durable tennis lines come at the expense of hitting the ball. Thicker tennis balls and harder materials are more durable, but they are not as flexible as thin and flexible nylon strings. If you often break the 16th nylon string, I suggest you use the same style of 15L tennis string, which can improve the durability of the string; in addition, you can also use the same specifications of polyester strings. Finally, if you use any size of tennis thread that is easy to break, the hard Kavila string will be the last choice. Its tough texture makes it the most durable tennis thread today, but the ball feel is different from other tennis balls. The line is poor.
String hitting
It is really difficult to conclude what kind of tennis line is best to play. Some players prefer tennis lines with high hardness and a crisper feel, while others believe that soft and comfortable tennis lines are easier to play. Generally speaking, a good tennis line needs to have good elasticity so that it can bounce back the ball at the moment of contact with the ball. The material, structure, and thickness of the string all affect its impact. The tennis line with the best elasticity (feel to hit) is still a natural cow and sheep bowel string. Although they were the first tennis lines to be used, there is no tennis line of any material that can exceed the feel of hitting the ball.
The strongest string
Kevila, one of the greatest inventions after the invention of relay nylon in the 20th century materials science research, was first marketed in 1971. Kavola is a new type of carbon material, which is made by polymerizing carbon. Its biggest characteristic is that it has a hardness that is higher than that of steel, but its density is comparable to that of glass fiber. This material was originally used to make bullet-proof clothing, and was later used in the production process of tennis rackets, which greatly reduced the weight of tennis rackets in the mid-to-late 1980s, and made hard contributions to the increasing hardness. This kind of material is also used in the production of ball tennis thread, the main feature is the excellent rigidity.
String weight
Among rackets, tennis lines, and string pounds, string pounds are the last factors to consider, but this is usually the least understood part of amateur players. Here are some common sense-within the range of recommended racket pounds, the lower the pound, the greater the power, and the higher the pound, the better the control. These effects are only achieved by players who reach a certain level, especially those players who are good at controlling the ball's landing point. Although beginners need a racket with better ball control, increasing the number of pounds worn by the string is definitely not a wise solution. What they need is not a higher number of pounds worn by the string, but by using a large racket face racket to improve the ball control . The middle-to-advanced players with faster swing speed and fierce batting usually need to give the ball better control. At this time, it is a good choice to increase the number of pounds. Except for individual players, these principles apply to most players.
Each racket has a "recommended string weight range", this range is usually the conclusion that the manufacturer invites professional players to try out, so if there is no special need (such as the need for greater power, suffering from tennis elbow, etc.) , You should start stringing from the middle of this range and make adjustments there.
power
As mentioned above, if a player wants to improve the racket's hitting power, he should try to reduce the number of pounds he wears. In this way, the elastic deformation of the tennis line will increase when the ball is hit (the elastic deformation of the ball will decrease), thereby transferring more elastic potential energy to the hit ball.
Controllability
An increase in the number of piercing strings will cause the elastic deformation of the ball to increase at the moment of hitting, so that the elastic potential energy transferred to the ball is less than the tennis line with a lower pound. This means that the flying distance of the ball will be shortened. Beginners who have not yet mastered the direction of hitting the ball will be more unable to control the line of the ball if they increase the string-pounding point. For middle-to-advanced players who are used to swinging heavily, a higher string-pounding point can keep them unchanged. The original hitting method also shortens the flying distance of the ball, so it is not easy to go out of bounds. In addition, most players believe that increasing the number of pounds on the string helps to improve the spin of the ball.
Arm injury
A lower string-pounding pound will reduce the vibration that is transmitted to the arm when hitting the ball, and can increase the dessert, thereby reducing the chance of arm injury.
Change racket
Many players are used to a certain number of pounds (for example, some people say "My string only wears 60 pounds."), and they will not adjust this when they change the racket. Whether the racket is replaced with a different head size, brand, or material, it is necessary to adjust the pounds of the string. If 60 pounds is the middle value of your recommended racket weight in the past, and the recommended racket weight for new rackets is 50-60 pounds, then you should start playing your new racket from 55 pounds.
Change tennis line
If you used nylon strings or bowel strings in the past, but now replace them with Kevlar strings or complex strings, it is recommended that you reduce the original weight of the string to reduce the hardness of the two materials to hit the ball. The impact. If you are changing to a double string, you can adjust the pounds downward by 5%; and when you change to the Cavalra string, you can adjust the downward by 10%. This adjustment can make your new tennis line hit the ball closer to the original tennis ball. line. On the other hand, when players replace nylon strings with polyester strings, they need to increase the pounds by 5-10% to compensate for the elastic fatigue caused by the polyester strings.
Strong string
The natural bowel string allows the racket's line bed to perform excellently in every game. It provides an excellent feel when touching the ball, and can hold the ball with good elasticity. The natural bowel string also has an unfamiliar characteristic. The tighter it is, the better its elasticity. Of course, this range is between 55-70 pounds. After being stretched out at higher pounds, the natural bowel string itself tends to continue to stretch, while other artificial strings begin to lose their elasticity when the pulling force continues to increase. In addition, if you unfortunately suffer from tennis elbow, natural gut will undoubtedly provide unexpected contributions to your game and arms.
"Australian Cannon" Philipsis can transform his thunderous power into a serve of more than 210 kilometers per hour, and the ball string he uses is completely natural. In the past, more than 60% of professional players have chosen natural bowels as their first choice for professional games. Although more than 80% of professional players now use other material strings, natural bowel strings have not completely withdrawn from history. In addition to players like Philipssis who continue to insist on the use of natural bowel strings, there are quite a few professions. Players will mix strings with natural bowel strings and other material strings.
