Racquets, Equipment, and the sort.

A tennis player's closest ally is his/her racquet, which allows them to actually play the game in a efficient way.

Another difference between the two eras were the availability of modern aged racquet technology and other equipment.  In the past the top pros used string made from cows intestines and wooden racquets that weighed almost a pound.  They played with a very flat style, trying to outhit the other opponent and go for winners.  Looking at the present game the idea is still the same, but with the more conservative playing styles, i.e. topspin.  Topspin is generated from brushing the racquet strings up the ball, which is done in order to put spin the ball causing a force to be applied to the ball and bring it down back into court, i.e. Magnus Force.  The past pros used topspin as well, but could not produce the amount the present top pros are able to put onto their balls.  This is due to the evolution of racquet technology and other equipment. The introduction to almost full graphite constructions has put wooden racquets away from the game.  With the torsional stability, along with the added stiffness on the racquet, pros can hit as hard as they want without over hitting the ball, as long as they use proper technique.  In order to add more control to their strokes they use new polyester and mixed polyester blended strings in their racquets, allowing them to brush up the ball more.
