Biomechanical Analysis On The Reverse Rotating Serving Technique Of Table Tennis

The purpose of this study is through the means of sports biomechanics methods, analyze the kinematic parameters of the collected of Table tennis serve technology of inverse rotation movement, make the motion trajectory of body segments and the racket more clearly on serve,The significance is to establish the theoretical basis for related scientific research, provide guidance to the technical action teaching and training.The study employs the method of literature and interview which lay a solid theoretical foundation for this research. It carried out by means of sports biological research projects and experimental method to test athletes for data acquisition. In the process, two Nissan Panasonic NV-MD9000 cameras are used as the filming equipment, 8 level-two athletes from sports training professional of Beijing Sport University as experimental objects, shooting the inverse rotation serve technical action by Three dimensional. Finally, ARIEL/APAS 3D image analysis system of USA and DLT measurement method are adopted to analyze the initial video and experimental data. Conclusions Results include:The experimental results and the data clearly show the whole process of table tennis reverse spin serve skill. From the analysis of experimental data, we can get that how to swing to achieve the highest efficiency of power conversion which makes power through the racket on the sphere, eventually to spin serve the ball more. From the experimental data, we can also see that the impact of the level of change in body weight when serving on the ball rotation and reverse rotation speed. Experimental data and images can be further deduced that not only large joint but also small joint plays important part when serving. Take wrist joints and so on.In order to better promote the reverse rotation of the ball, make up table tennis reversal limitations and deficiencies that exist in training and being short of scientific guidance for the majority of coaches, these experimental data are particularly important when making training programs, which will make training programs more scientific and reasonable and the training improve rapidly. Learning all the major aspects in the process of reverse rotation, the action and the principle of each characteristic change in muscles and joints is of great practical significance for the efficiency in training. And this is one of the important significances of this study.
