A tennis racket is usually rarely bought, once in a few years, for several years, and often for the first time in life. During this time, technologies used in the production of rockets are changing dynamically. Many racket parameters affect the pleasure and progress in the game of tennis. Descriptions of the main parameters of the rocket should be located on its frame (in different places). However, they are often difficult to read, especially for novice players. In order to facilitate the appropriate selection of the racket and understanding its parameters, we present below the main features that you should pay attention to when buying a racket, so that it is most accurately matched to the individual predispositions of the player.
Rackets have different shapes and different sizes of heads. When it comes to the shape of the head, there is no clear assessment of what shape is ideal and recommended for the appropriate group of players. Most of the heads are in the shape of a "classic egg". There are clearer classification rules for the size of the racket head. The size of the racket head is given in centimeters and / or square inches and refers to the surface area. The surface of the racket head is responsible for the force and precision of the strike.
There are three basic sizes of racket heads:
Summarizing, it can be assumed that:
The length of the racket is the distance from the base of the handle to the end of the racket head. The standard adult racket is 68.58 cm (27 inches) long, by far the most on the market. Extended rackets (even by a few centimeters) increase the range and strengthen the force of impacts, as well as provide better service and ball rotation. Instead, they reduce ball control. The lower maneuverability of the extended rackets is especially noticeable when playing at the net. Standard rockets are more dynamic. Shorter lengths than the standard ones are junior rackets. The physical conditions of the child are an important factor in the selection of rackets for children. The height and weight of a child may contribute to the fact that physically grown children should use rackets a little longer than recommended by the manufacturer.
Division of rockets due to length:
This is a very important factor in choosing the right racket. The weight of the racket for an adult player may vary between two hundred and three hundred grams.
The balance of the racket is the center of gravity of the racket. It is measured in centimeters from the shoe to the tip of the head. In this respect, the rackets can be divided into: balanced on the head - HH (head heavy), balanced on the handle - HL (head light), balanced evenly - EB (even balance). Two rackets with the same weight but differently balanced give a completely different feeling when playing. Rockets with a center of gravity shifted towards the handle have a lighter head and are more maneuverable. They are great to play with the net. Head-balance rackets usually belong to the group of light rackets. By shifting the center of gravity towards the head, the player can spend less energy to deliver a strong hit. These types of rackets allow for a dynamic "swing" during the game. Rather, they are intended for beginners. Center-balance rackets have an evenly distributed weight. They offer the player a balanced power and impact control. Handlebar balance rackets are rather heavy rackets. Their head is lighter. This translates into a less dynamic "swing" but better controlled strokes. These types of rackets are most often chosen by advanced players.
Swingweight - weight sensation throughout the entire strike cycle. This parameter depends on the mass of the rocket, balance and aerodynamics (including the size of the head). And the selection in terms of this parameter depends on the physical build and strength of the player:
Racket stiffness, which is how much the frame deforms when it contacts the ball, is measured in RA units. Stiffer rackets allow for a stronger impact, but more shocks are transferred to the wrist. Flexible rackets give you more ball control and put less strain on your wrist.
The division of rackets due to the flexibility of the rocket frames:
Rocket frames have different thicknesses. There are those that have the same thickness along the entire length, while the thickness of others is variable. You can classify the racket frames according to the frame profile into three groups: thin, medium and thick:
Until a few decades ago, wood was used to produce rockets, with time aluminum. The main disadvantage of these rackets was their weight, which made maneuvering difficult and at the same time easy to play and led to frequent injuries. With time, tennis equipment production technologies were improved.
Currently, the production of tennis rackets is used:
Aluminum rackets are the most flexible, but also heavy and transfer a lot of vibration to the wrist. That is why they are not very popular among players who prefer to choose rackets made of graphite composites, made of graphite only, or with the aforementioned additional materials (boron, kevlar), which make the racket light and durable. Tennis racket manufacturers have their own trade names for the materials and technologies used in racket production.
The most popular arrangement of strings is the arrangement (vertical / horizontal ratio): 18/20 and 16/19. There are also other layouts such as: 18/19, 16/18, 14/18 and others. Due to the density of the string arrangement, there are two basic arrangements: open "open" (a rare arrangement of strings, e.g. 16/19) and closed "close" (dense 18/20 string arrangement)
The string system (tension) is open
Closed string system
Racket manufacturers provide the recommended tension force, measured in kilograms, with which they recommend stringing rackets with a tolerance of +/- 2 kg. Tighter strings in the racket give more control of the ball, but reduce strength, dynamics and rotation. Increasing the string tension also makes the game less comfortable, as more adverse effects from hitting the ball will be transmitted through the racket frame to the player's body generally. Weaker racket string tension reduces ball control (the catapult effect is often cited). However, we will achieve greater dynamics of strokes and rotation, because the ball stays on the strings longer and "bites" more into the racket.
An important detail is the appropriate adjustment of the size (circumference) of the racket handle to the player's hand. There should be markings on the size of the racket handle on the racket. The American method specifies the handle circumference in numbers from 0 to 5 (often the letter L or G is added), while the English method specifies the handle circumference in inches from 4 to 4 and 5/8 inches. Size L (G) 0 is 4 inches, L (G) 1 - 4 (1/8 inch), L (G) 2 - (4 1/4 inch), L (G) 3 - (4 3/8 inch) ), L (G) 4 - (4 1/2 inch), L (G) 5 - (4 5/8). The correct grip is when the index finger of the other hand is between the ball of the thumb and the fingertips of the racket holder. The most popular handle sizes are L (G) 3 and L (G) 4. Small women should choose a handle size - L (G) 1. Teenagers, women and men with medium and short stature (rather short fingers) should choose handle size L (G) 2 and tall people (with long fingers) - L (G) 4 or L (G) 5. When we are not sure whether to choose, for example, handle 3 or 4, remember that it is always safer to buy a racket with a thinner handle and possibly thicken it it with a wrapper, the so-called overgrip. The Head company was the first to use the so-called "interchangeable handles" so that you can thicken or slim down the racket handle depending on your needs.
There are several dozen manufacturers of tennis rackets known on the market, producing several hundred models of tennis rackets. Every year, new rocket models with new technologies and new, fashionable colors appear on store shelves. However, the rules for selecting rockets, especially for beginners, for whom it is often the first rocket in their life, can be simplified. This is an important choice because the selection of the right racket will partly depend on whether you like tennis and become a way of spending your free time. Based on the characteristics of the rocket parameters described above, beginners should be guided by the following guidelines when choosing a rocket:
Rączka to uchwyt, który gracz trzyma w dłoni. Rozmiar rączki określa jej obwód. Rozmiary rączek rakiet tenisowych oznacza się na dwa sposoby:
[cale / ≈ cm]
4 / ≈ 10
4 1/8 / ≈ 10,4
4 1/4 / ≈ 10,8
4 3/8 / ≈ 11
4 1/2 / ≈ 11,4
4 5/8 / ≈ 11,8
[cale / ≈ cm]
Uwaga! Oznaczeń w centymetrach nie znajdziesz na rakietach. Przeliczyliśmy cale na centymetry po to, by ułatwić Ci dobór właściwej rączki, jeśli nie masz możliwości wzięcia rakiety do ręki, np. chcesz kupić ją w sklepie internetowym.
Informacja o rozmiarze rączki znajduje się zazwyczaj na jej stopce. Rozmiar rączki, czyli uchwytu rakiety jest bardzo istotny, jednak, w przeciwieństwie do główki, nie dlatego,że dobierając różne rozmiary rączek osiągnie się różne efekty w grze,
Obwód rączki musi być dokładnie dopasowany do wielkości dłoni gracza, bo tylko wtedy zawodnik może mieć gwarancję,że jego chwyt będzie pewny, rakieta będzie stablilnie leżała w dłoni, a nadgarstek nie będzie obiciązony.
Określenie rozmiaru rączki rakiety
(gdy jest możliwość wzięcia rakiety do ręki)
- należy chwycić rakietę jak pokazano to na powyższym rysunku - jeśli palec wskazujący drugiej dłoni mieści się dokładnie w przestrzeniu między kłębem kciuka a czubkami palców, oznacza to, że rączka ma właściwy rozmiar. - jeśli między kłębem kciuka a czubkami palców jest zbyt dużo miejsca i palec wskazujący nie wypełnia tej przestrzeni oznacza to, że rączka jest za duża i należy wybrać rakietę o mniejszym obwodzie rączki. - jeśli natomiast palec wskazujący nie mieści się oznacza to, że rączka jest za mała i należy wybrać rakietę o większym obwodzie rączki.
(gdy nie ma możliwości wzięcia rakiety do ręki i oceny grubości rączki metodą palca wskazującego)
- należy wyprostować dłoń i zmierzyć odległość od jej środka do czubka palca serdecznego - otrzymany pomiar w centymetrach należy porównać z tabelą rozmiarów, która jest powyżej
