Tennis equipment : 

Tennis equipment Tennis equipment is simple in terms of how much you need – the only tennis equipment that you really need to play a good game is a racket and a ball. http://www.e-tennis.org/tennisequipment.html

Rackets and Balls : 

Rackets and Balls Rackets. A major part of your game is dependent on how powerful and how fit your racket is for your game. Power and shock absorption are two things that you must consider in choosing a racket. Check the material and stiffness of the racket strings to see whether it is the racket for you. The store attendant can help you in deciding on your racket. Check the balance and the weight, as they can affect the way you control your racket and how you maneuver on the court. Balls. There are different types of balls, and those differences can affect your performance. http://www.howtodothings.com/sports-recreation/equipment-required-to-play-tennis http://upload.wikimedia.org/wikipedia/commons/d/d7/Real-tennis-rackets-balls.jpg

How has the tennis racket changed over years? : 

How has the tennis racket changed over years? Although aristocracy played variations of the sport of tennis for centuries, modern-day tennis (called lawn tennis at the time) was introduced in the 1870s. The rackets were made from wood that was formed into various shapes that were similar to today's keyhole rackets. Wooden rackets were generally heavy and had small sweet spots for hitting and delivery. The steel frames had a huge sweet spot, were lighter and increased the player's power. They were used by advanced players and also attracted generations of new players to the game. Graphite rackets provided stiffness, but were still a bit heavy. They were later injected with foam to reduce the weight. The ultra-light racket, made from aluminum, proved a mixture of power and control. Graphite technology kept improving, so bigger and lighter rackets could be also produced. Titanium technology, introduced in 1998, made rackets ultra light and powerful and added vibration dampening to help absorb impacts and keep the racket in top shape. http://www.livestrong.com/article/15683-tennis-rackets-have-changed-throughout/

How polymers improved tennis rackets? : 

How polymers improved tennis rackets? Due to good durability and good resistance to moisture, a variety of synthetic polymers have been formed into strings for use in tennis rackets. These synthetic strings have not proved entirely satisfactory, however, because they generally lack the low damping of gut and sometimes elongate when exposed to higher temperatures, thus losing the necessary tension in the stringed racket. http://www.freepatentsonline.com/4395458.html

How did the balls change over years? : 

How did the balls change over years? Historically, balls were either black or white in colour, depending on the background colour of the courts. In 1972 the ITF introduced yellow tennis balls into the rules of tennis, as research had shown these balls to be more visible to television viewers. Until high altitude balls were introduced into the rules in 1989, only one type of tennis ball was allowed. The Type 1 and Type 3 balls were introduced into the rules in 2002. The range of forward and return deformations - the change in the ball's diameter under an increasing and decreasing load of 8.165 kg - have varied over the years, reaching their current values in 1996. http://www.itftennis.com/technical/equipment/balls/history.asp

How polymers improved tennis balls? : 

How polymers improved tennis balls? Examples of natural polymers employed in tennis are not hard to find. Leather (essentially woven collagen) was the first material used to make comfortable, high friction grips, although now it has largely been replaced by PU. Natural gut string is made from the outer skin of cows’ intestines, known as serosa (also made up of collagen) and natural rubber (polyisoprene) is used in tennis ball cores. http://www.itftennis.com/technical/questions/glossary.asp
