| Through the methods of document consultation, laser speed test, video recording, kinematic analysis and comparison analysis, the authors monitored the run-up speed velocity of Yang Quan at the different phases of training and competition. The characteristics of his run-up speed are analyzed so as to find out the most satisfactory run-up mode, which will bring his jumping skill into full play. The result shows that the outstanding run-up speed is the foundation for Yang Quan to improve constantly his technical level and the guarantee for future high performance. The strong point of his run-up speed should be improved steadily and effectively. The technical level of the other links should be raised correspondingly. The specific jumping ability which matches the run-up speed should be strengthened and the performance and perfectness of the clearing movement should be further improved. |
