The origins of the 15, 30, and 40 scores are believed to be medieval French. The earliest reference is in a ballad by Charles D'Orleans in 1435 which refers to quarante cinque ("forty-five"), which gave rise to modern 40. In 1522 there is a sentence in Latin "we are winning 30, we are winning 45". The first recorded theories about the origin of 15 were published in 1555 and 1579. However, the origins of this convention remain obscure.
We also slide the non-dominant hand from the throat down to the handle while we’re changing the grip. This somewhat complex move has to be practiced for a while so that it becomes quick and eventually completely subconscious. From there, we again let the racquet drop and fall behind us. Then we pull it through the familiar contact point and follow-through stages that we already mastered.
This tennis racquet from Head is both affordable and very functional. It is an excellent quality entry level tennis racquet that most beginners will really find to their liking. It has a good grip that fits smaller size hands well and it is constructed out of materials that keep it stiff as you hit the ball to help generate extra power on your shots.
In a legal service, the ball travels over the net (without touching it) and into the diagonally opposite service box. If the ball hits the net but lands in the service box, this is a let or net service, which is void, and the server retakes that serve. The player can serve any number of let services in a point and they are always treated as voids and not as faults. A fault is a serve that falls long or wide of the service box, or does not clear the net. There is also a "foot fault", which occurs when a player's foot touches the baseline or an extension of the center mark before the ball is hit. If the second service is also a fault, the server double faults, and the receiver wins the point. However, if the serve is in, it is considered a legal service.
In some tournaments, line judges who would be calling the serve, were assisted by electronic sensors that beeped to indicate the serve was out. This system was called "Cyclops". Cyclops has since largely been replaced by the Hawk-Eye system. In professional tournaments using this system, players are allowed three unsuccessful appeals per set, plus one additional appeal in the tie-break to challenge close line calls by means of an electronic review. The US Open, Miami Masters, US Open Series, and World Team Tennis started using this challenge system in 2006 and the Australian Open and Wimbledon introduced the system in 2007. In clay-court matches, such as at the French Open, a call may be questioned by reference to the mark left by the ball's impact on the court surface.
I was born in Colombia but lived all my life in Venezuela. I got a tennis scholarship at Oklahoma, where I got my bachelor degree in Psychology. I worked as head pro at Club Nautico De Maracaibo in Venezuela for 23 years where I made lots of friends and made a lots of great players! 8 players I have taught played tennis for colleges here in the USA. I am a real friendly person and very serious about tennis. Sincerely yours, Jose

Standard squash rackets are governed by the rules of the game. Traditionally they were made of laminated timber (typically Ash), with a small strung area using natural gut strings. After a rule change in the mid-1980s, they are now almost always made of composite materials such as carbon fiber or metals (graphite, Kevlar, titanium, and/or boron) with synthetic strings. Modern rackets are 70 cm long, with a maximum strung area of 500 square centimetres (approximately 75 square inches) and a mass between 90 and 200 grams (4–7 ounces).
Vibration dampeners (also sometimes known as "gummies") may be interlaced in the proximal part of the string array, to reduce the percussive sound of the ball hitting the strings and/or to reduce perceived vibration. They do not, however, reduce impact shock significantly, so they are of no safety value. Some professionals, such as Andrei Agassi, used rubber bands instead of specialized dampeners. Dampeners come in two main types. The first uses the two central main strings to hold it in place. The second is sometimes called a "worm" and it is woven between many of the main strings. Dampeners are nearly always placed very near the bottom of the racket string bed.
The purpose of the Northwest Louisiana CTA is to make an positive impact on the tennis community by providing support and resources in the development of programs, events, leagues, and facilities promoting tennis as a lifetime healthful sport within North Louisiana to all ages and all skill levels. The NWLACTA will collaborate with the USTA and other associations and programs in the pursuit of these goals.
