The serving technique we described earlier with a compound rotation of the racket (Loop for various strokes in tennis) is a real chance for boxers to percieve tennis.
If you perform any classic version of the serve with a rigid hand of a boxer, the loop will be poor, and the boxer, who is playing tennis will have to strain greatly all his muscles, especially the abdominal muscles.
And this manner of playing does not give a feeling of flying, in which is the essence of tennis.
Other technics of the game get along well with the boxing hand, but when playing volley it is useful to hold the racket closer to the middle (not by the end of the handle). And this kicker can be useful for players with any type of hand.
But when smashing the ball, a hard hand will protect from performing unnecessary(in this case) loop.
