By using three-dimensional video analysis, we made a kinematic analysis on Grigor Dimitrov’s Serve technique, aiming at finding the kinematic characteristics of his serve technique during various stages. The results showed that: (1) During the stage of tossing the ball and lifting the racket, the tossing height of the ball was at minimum appropriately, while the elbow extension of the tossing arm was stright, and the angle of his left knee was 95.4°, which is beneficial to making greater kicking power; (2) At the back-swing stage, Dimitrov’s both feet made a great range of pedal and stretch quickly, and the “scratch-back” posture is obvious, and momentum caused by the kicking and coxae-turning was rather large; (3) When hitting the ball, the contact point was accurate and the speed of the racket head was high, which passed a relatively large initial momentum to the ball; (4) Dimitrov’s entire service action was integral and coordinate, smooth and powerful, which was in accordance relatedly with kinematic characteristics
Key words: Tennis serves / kinematics analysis / 3D video analysis
