Abstract

With the general development of sports in the world, people began to pay more and more attention to the tennis service technology. However, there is no better way to effectively analyze the techniques and actions of tennis teeing. In order to effectively analyze the tennis teeing technique, this paper uses fuzzy mathematics method to construct a fuzzy evaluation model to evaluate and analyze, which provides a lot of theoretical basis for training. Through research, we found that the athletes adopt the FB station technology, adopting the back pendulum upwards, and the flexion and extension of the lower limbs are sufficient, increasing the distance between the head and the ball, and obtaining a better posture for the body; the tossing is too high, throwing the ball direction is better. Whether the domestic or foreign offensive athletes are the first choice in the first serve, the outside corner is the first choice, the foreign player's outer corner selection rate is 53.6%, while the foreign player's outer corner selection is 51.2%, in which the domestic player's outer corner success rate is reached 71%, foreign players reached 76%.
