A kick serve becomes less effective when the returner can predict when it is coming. Because of the greater spin, a kick serve travels less slowly. If the returner can position himself to strike the ball before the kick takes effect, he can punish the return severely. Many servers use the kick serve as their second serve; however, they must still occasionally throw in a slice second serve to prevent returners from getting grooved on their returns.
Almost all of your joints are used in tennis, but the main ones in a tennis serve are the knee joints, and elbow joints.
You can hit an underhand serve in tennis; however, the overhand serve is more effective because it is more powerful. That is why you don't see the underhand serve used much.
Badly.
a serve
Tennis players learn several different serves as they are learning the game. There is the hard, flat serve that usually goes down the middle of the court. There is the spinning slice serve that usually kicks out wide by the time it gets to the returner. There is also a topspin, or kick serve that bounces high at the returner. Players often have a favorite but learn to use them all to gain an advantage over their opponent.
