Young Blonde Girl Reveals On The Court With A Tennis Racquet

Longer racquets were introduced by Dunlop in order to give additional reach for shots such as the serve and volley where shorter players may be at a disadvantage. Midsize or mid-plus racquets are the general standard for professional players.
Stringing (material, pattern, tension) is an important factor in the performance of a tennis racquet. A few elite players use natural gut, but the vast majority of strings are a nylon or polyester synthetic. Some (American champion Pete Sampras is a prominent example) consider the natural string to be more responsive, providing a better "feel", but synthetic is favored for its much superior durability, consistency, as well as much lower cost. String pattern (the vertical/horizontal grid) is a function of the racquet head size and design. A tighter pattern is considered to deliver more precise control; a more "open" pattern to offer greater potential for power and spin. Modern racquets are marked with a recommended string tension range. The basic rule is that a lower tension creates more power (from a "trampoline" effect) and a higher string tension creates more control (the less 'trampoline effect' the more predictable the power and angle of the departure from the string bed.)
Double strung tennis racquets were introduced in 1977 and then banned because they permitted excessive spin. A modern version of a legal double strung racquet has been introduced.
