Like most sports, there are various pieces of tennis equipment needed to play the game. It is important for players to choose the right tennis equipment, particularly when it comes to rackets, in order to play the game effectively. The main pieces of tennis equipment are rackets, balls and shoes. Other pieces of equipment such as shirts and shorts/skirts are needed but these do not particularly affect the performance of players as much as rackets, balls and shoes.


The racket is the most important piece of equipment in tennis for obvious reasons. It should be comfortable to hold and feel like an extension of the arm. There are any amount of rackets out there of varying weights and lengths. Normally, there are 4 groups of tennis rackets. These are the beginner, intermediate, advanced and junior rackets. Anyway, here are the top 10 intermediate racquets if you still can't decide what you will get. It is down to individual choice as to which weight and length best suits each player. The standard length of an adult size racket is around 27 inches and around 15 inches for a junior player. There are restrictions however on length and width of rackets. They must be no longer than 29 inches (73.66cms) including the handle and 12.5 inches (31.75cms) in width. The playing surface of the racket head should be no more than 15.5 inches long (39.37cms) or 11.5 inches wide (29.21cms). There are no restrictions on the weight of rackets but all modern rackets are made to be as light as possible. Most modern rackets are made from lightweight materials such as fiberglass and graphite. Laminated wood frames were used before these, up until the 1970s. The lightweight materials allowed racket heads to become bigger and enabled players to have more control of the ball and generate more power and accuracy. The strings are a crucial part of the equipment of a racket. Generally, the tighter they are strung the better it is for generating control and spin. If there is slightly less tension in the strings, this tends to allow for more power to be generated. Traditionally, strings have been made from animal gut, which is seen as the best material to maintain a high level of tension. The majority of professional players use animal gut but it can be expensive so most players at lower levels of the game use strings made from synthetic materials such as nylon. Attention should also be paid to tennis grips. They should not be too big as this will cause a strain or too small as this can lead to damaging the hand, wrists or elbows. A good way to find out the correct grip size is to measure the distance from the middle crease of the hand to the top of the ring finger.


The next piece of equipment is, of course, tennis balls. The core of the ball is made from rubber with a wool or nylon shell on the outside known as the nap. The ball must be between 2.5 inches (6.25cms) and 2.63 inches (6.57cms) in diameter and must weigh at least 56 grams, but no more than 59.4 grams. It is often the case that balls are changed a number of times during a tennis match. The reason for this is that official rules stipulate that they have to bounce between 53 and 58 inches after being dropped on to concrete from a height of 100 inches. As they are being used, tennis balls tend to lose pressure and this affects bounce. It is also the case that the fluffier and tattered a ball becomes the slower it flies through the air so players prefer using balls that are smoother.


In general, any type of trainer or shoe can be used to play tennis. However, if it is possible it best to try and use trainers designed specifically for the game. The sole grip is a crucial part of tennis equipment as players need traction to move in different directions on various types of surface. A herring-bone tread is regarded as the best type of grip to use. Players need to slide a lot too, so specially designed trainers allow them to slide safely by having extra ankle and side supports.


So, that's the basic equipment in order to play tennis comfortably. As you gained more experience,  you can customize your racquet to your liking and choose other types of string if you want to.

  ti-nspire review The Texas Instruments TI-Nspire is a graphing calculator that is designed exclusively for students of any math class. Its technology allows students to see and make connections with up to four problems at a time on one screen. Bonus: Get the best graphing calculator from, if you are not interested in Ti-Nspire. The CAS version is better and newer. These four representations of a problem include algebraic, numeric, graphical and written formats. All these can be viewed and studied in real time. This is an ideal choice for students struggling in math class. They can learn different types of equations and expressions by watching the practice problems being produced. They can also get an idea about how various concepts are linked. These functions help students sharpen their critical thinking skills because they will be able to actually see mathematical patterns and relationships. ti-nspire-cx-games The TI-NSpire graphing calculator contains functionality similar to that of a computer. Students can even create, save, and edit documents. This means that if a user runs out of time when inputting an equation, he/she can save the progress and resume later. For instance, students can study the relationships of rise, run and slopes by using a graph on the TI-NSpire. This handheld device can be used on all the important high school exams, such as the ACT, PSAT and SAT.  Corresponding software can be attained online, along with other applications and packages. Studies show that the use of apps makes students feel more excited and interested in math! Even students who normally claim to hate math class find that learning can be easy with the TI-NSpire graphing calculator. What’s more, this hand held device can be used for scientific purposes as well as mathematical! Here are some details about the TI-NSpire: PROS
  • It’s ideal for Geometry, Trigonometry, Pre-Calculus & Calculus, Pre-Algebra and Algebra 1 & 2.
  • Dynamic, instant linking from one representation to another in real time.
  • Multiple representations of the same problem or representations on different problems, all at once.
  • Computer interface and cursor controls.
  • Easy navigation between various functions and screens.
  • Rechargeable battery
  • Snap-in, TI-84 keypad.
  • Can be hooked up to the PC for downloading programs and even games!
  • Can be used to solve any type of math problem for any math class.
CONS As with all graphing calculators, there are unfortunately a few cons of the TI-NSpire, including:
  • The high cost.
  • Lack of speed.
  • Large, bulky size.
  • The snap-in keyboard may be a con for some rather than a pro.
  • Those who always seem to lose or drop everything need to be extra careful.
CONCLUSION Obviously, the pros outweigh the cons, making the TI-NSpire a great Texas Instruments calculator. New TI-NSpires can be ordered on the internet for $129.99 or so, depending on the store. The average price for a used one is about $85.  Usually, a warranty is provided for new purchases.
