Abstract: Analysis of the gap of tennis service skill between China’s players and the world’s top players indicates that the opinion that tennis service is under the server’s absolute control is not true. The author puts forward for the first time the systematic service skill, namely, the service skill is a complete system and excellent players should pursue the synthetic and coordinated effect in their service. The effect includes: (1) synthesis and coordination from static to dynamic; (2) synthesis and coordination of various elements (subjects) involved in service; (3) synthesis and coordination from external to internal. Based on the above opinion, the author proposes a synthetic and coordinated tennis service training system which contains: (1) prioritizing coordination in the service training and make it play a dominant role in the service process; (2) attaching importance to the coherence between service and the following action; (3) integrating the body movements along the vertical line and use the overall strength; (4) improving the synthetic and coordinated effect through maximizing the efficiency and minimizing the energy consumption; (5) developing individual’s best service rhythm. The paper also points out the 6 special abilities that athletes should have if they want to achieve the above effect.
