Tennis terminology is an integral part of the theoretical training of a tennis player. This article contains the most common terms related to the parameters of rackets, strings, other equipment and the game as a whole.
Actual tension. This is the tension of a stretched racket, which will be almost always lower than that installed on the machine. This occurs in most cases due to the weakening of the strings or their crawling. As a result, a racquet stretched with a pulling force of 60 pounds can actually have a stretch of 50-55 pounds. It depends on the size of the head, the type of string and the machine used to stretch.
Balance. A static measure of the distribution of weight in a racket, measured from the end in inches or centimeters. The gaming characteristics significantly depend on the balance. Usually referred to in paragraphs. Each item is 1/8 inch. Usually heavy racquets have a light head to maintain maneuverability. At the same time, most of today’s super-lightweight models have a balance in the head to provide enough mass (which translates into power of punches) in the area where contact with the ball occurs.
Transverse section. This is the diameter of the rim of a racket or string. Usually measured in millimeters. Frames with a large cross-sectional width are stiffer than narrow frames. As for strings, thicker ones will be more durable and reliable than thin ones. Rubber vibration dampers reduce only string vibration.
Damping. Usually refers to vibration or shock damping. The technologies used in the handles are designed to dampen the vibration before it reaches the tennis player’s hands during contact with the ball. Weight is also effective in reducing the effects of vibration and shock.
Elasticity. This term in tennis is used quite often. It is used to describe string stretching and convenience. Elasticity is the ability of a string net to return to its initial position after contact with a tennis ball. The following factors influence this: the material of the string, its structure, size and tension. Over time, the strings lose their tension and elasticity, making them play unproductive and requiring great effort from a tennis player.
Starting point. Sometimes it is also called the moment of weight lifting. This is an indicator that gives an idea of how the racket feels when it rises beyond the end of the handle. This is a tough static measure of maneuverability, based on weight and balance. The formula by which you can calculate the initial moment is the mass (measured in grams) multiplied by the balance (measured from the end in centimeters), divided by 100.
Penetration depth. A universal measure of string diameter in the USA. Most tennis strings have a penetration depth of 15-17, and only some specialized ones have 18-20. The higher this parameter, the finer the string, usually measured in millimeters. Half the unit of penetration depth is represented by the letter L. Thus, the inscription 15L means that the penetration depth is between 15 and 16.
Thin strings have better playing characteristics compared to thick ones, but their service life is much shorter.
Thin strings offer a better ball feel, power and potential for rotation than thick strings made of the same material and construction. Although the Tennis Industry Association has standardized the specification of penetration depths, do not assume that all strings with a penetration depth of 16, for example, are the same. One company can measure a penetration depth of 16 equal to 1.28 millimeters, while another will measure it at 1.32.
Pen size. Standard sizes range from 4-1 / 8 to 4-5 / 8 inches. The most common method for measuring the handle is as follows: you need to take a racket with an eastern grip (with this grip, the palm should be on a plane parallel to the plane of the string surface). With the optimal thickness of the handle, you can stick the index finger of your free hand between your palm and ring finger. Obviously, the preferences of tennis players allow you to make exceptions to this rule.
So far, many experts advise using the largest handle that you will be comfortable playing. Keep in mind that it is much easier to increase the handle. If your size is between the standard ones, take a smaller one and wind an overgripe, or use a special sleeve to increase the handle.
The size of the head of a racket. This term refers to the area of the stretched area and is usually measured in square centimeters or square inches. A larger head provides increased power and an increased playing spot, while a smaller one gives more control. Although there is no industry standard for head size, there is an unofficial classification.
