Abstract
According to the actual situation of volleyball training in China, a set of statistical information collection and analysis system for volleyball games is developed. The system collects and processes all kinds of technical and tactical information intelligently and interactively, so that competition data and technical and tactical data can be interrelated. This system can retrieve and process related videos according to technical and tactical indexes, so that the technical statistics and video display of athletes in training can be unified. Then the dynamics models of gravity, buoyancy, additional mass, motion resistance and Magnus lift in volleyball movement are established, and their motion trajectories are numerically simulated. An accurate calculating model of volleyball motion trajectory is established based on the analysis of initial velocity, angular velocity and vertical displacement. The correctness of the model is verified by numerical simulation.
