The tools used for exercising will not only grow over time, to maintain accuracy and improve ease of use, but their development almost always tells a story. The same can be said about the missile sites. Not only tells the story, but the game of tennis determines the physics at work.
A tennis racket consists of a cozy a frame with wide open rim through which extends a network of strings or katguta (animal intestines). The main part of the rocket is the head, rings, face, neck, back, cover and the strings. In the case of several missiles in a modern style, some of katgutów have been replaced by synthetic fibers such as nylon or other polymers that provide added strength. Tennis rackets have a length of from 21 to 29 inches, depending on age and skill level of the intended player, and the longest rocket used by professionals. The size of the head of the missile is directly proportional to the level of power that is transferred to the ball during impact during intense combat. The more head, the more fussy, the error becomes when striking the ball close to the rocket.
But wait. Or just need the hit the ball in the net? The easiest way, Yes. However, the story is much more. Effective kick the ball a good rocket includes trójskładnikowy system between the ball , the frame of the rocket and its strings . The missile itself does not have to be absolutely rigid. In fact, all three components are to some extent flexible. This is intentional so that the ball has transferred some of its kinetic energy to the frame of the racket, its strings, while the remaining energy is then used to send the ball back to the other side of the tennis court.
Level the string tension is adjustable to provide the player different power levels. For example, when the rope becomes more and more dense, also increasing the degree of accuracy after hitting the ball. This means less deformation of the strings, which makes the angle and power of hitting the ball, are more dependent on the hand movements and skills. In contrast, if the design of the lace is free and open, increasing the deformation of the ligaments, which means they have a direct impact on the power and spin of the ball. Line low voltage still require skills, because you need time to figure out where the weak spot of the rocket and how best to use it.
Regardless of whether the frame is made of wood, metal or composite material, more rigid than strings or a bullet, so has less flexibility. However, a certain amount of kinetic energy is lost on impact of the frame in the ball. Because of this, some believe that rigid boundaries, the less the loss of energy.
Rackets to choose from
For the novice tennis elbow large sweet spot and comfortable, non-slip handle, it is very important that you feel the game atmosphere and energy. Some missiles also offer heads with colored filling that evenly distributes the shock load on the entire frame, which provides better control.
If you are sensitive to shocks buses, finding the missiles from the integrated vibration reduction / cushioning of the shocks may make it so that the game would be better and less awesome.
Lightweight and durable materials (e.g., Graphite , titanium ) is specified, because the last thing you want is ridiculous heavy rocket, which is difficult to hold or to swing. The most important is the ability to check the rocket before buying it, to make sure that the game is as convenient and efficient as possible.
From monks to modern times
Tennis has a long history Dating back to the XI century, when French monks used their rockets to play in first game. Since then, much has changed.
The first real tennis racket is made of solid wood in 1874, in London, major Walter C. Wingfielda .
A lot of the early rockets that have occurred in the forties of the last century, built of laminated veneer lumber glued laminated timber (i.e. Ash, maple, and okume) to improve strength changes of wood.
In 1968. The company Wilson Sporting Goods has developed a rocket T2000, which was made of steel. In the same year, Spalding released the first aluminum racket called the Smasher. In 1975 the first wonderful aluminum rocket was made for Weed. Although aluminum was still less accurate than the earlier wooden models, it ponadwymiarowa rocket paved the way for the development of more custom sizes of missiles for extra diversity.
In the early eighties, thanks to companies like Dunlop and Prince, wooden design was the protagonist in the use of composites of carbon fiber. The composite design has the advantage that it is very easy and still this is the current standard for modern tennis rackets. Today the emphasis is on adaptation of rockets, such as racket Prince O3, which has a large hole for the filament that improves aerodynamics and speed.
