By the comparison and the analysis of the different factors during the tennis Top spin serve motion such as the required time per section, the movement displacement of the racket, the velocity of the upper limbs joints, the physical center of gravity, and the angle and the angular velocity of the upper limbs joints between an ace player and a mediocre player, these following results were drawn.
First, the experiment result of the total time required per section in a tennis Top spin serve motion showed that an ace player was faster than a mediocre player by 0.4 seconds. This result suggested that it was required to increase the speed of the racket head by a swift swing to perform an effective flat serve motion.
Second, the velocity of the wrist joints of gravity of an ace player was faster in every phase than that of a mediocre player in a tennis top spin serve motion.
Third, the velocity of the upper limb joints of an ace player was faster in every phase than that of a mediocre player in a tennis Top spin serve motion.
Fourth, at the moment of impact of a tennis Top spin serve, an ace player had greater extenton of the angle of the wrist joints by an 4 degree than a mediocre player. An ace player also had greater extension of the angle of the elbow joint and the shoulder joint respectively by a 2 degree and a 4 degree with a mediocre player.
Fifth, an ace player was shown to have a greater change of the forward and the backward inclination (or the anterior and posterior inclination) of the upper body
