| Men's hockey program is the traditional advantages of the project in Gansu Province, has been established since 1987, has repeatedly made in the excellent results in national competitions, but there is a certain gap from the impact of Champions. Asia Plateau is located in Gansu Province, has certain advantages in physical, as the technical, physical sports-oriented classes, lack of technology also will hinder the overall level. Hockey short corner as a modern means of the main points, the extent of their technology skills to some extent determine the outcome of the game, Gansu Province hockey short corner in the scoring rate of 30%, while world-class competition short corner goals 50%, Gansu Province, hockey short corner men, the lower success rate may affect the overall strength of the main reasons. Hit category as sports, field goal is the main purpose was shot accuracy is particularly important in the short corner, the pull-shot injection technology as the most important ways, the problems may restrict the overall development of the main bottleneck. This study attempts to use kinematic means, starting from the sports techniques to explore the men's field hockey players of Gansu Province sports techniques and sports performance relationship, seeking the reasons behind the leading sports performance. Gansu province is therefore necessary to pull men's field hockey short corner shot technical analysis, provide theoretical support for scientific training. In addition, the domestic research scholars Hockey little less on technology research, and research on technology is only the principle of the technology, the lack of in-depth systematic research study in Gansu Province has not been on the hockey.In this study biomechanics ways and means, using three-dimensional high-speed camera technology to the level of Gansu Province, the highest men's field hockey team four players short corner as the research object (in the hockey game, pull radio technology is a specialized technical training , a dedicated athlete), through literature, expert interviews, a large number of high-speed camera law to collect relevant data and experimental data, the use of moving image analysis and mathematical statistics on the players pull a short corner shot action parameter analysis technique, combined with athlete, physical indicators and training arrangements, from the overall diagnosis of technical movements of athletes, athletes technology to identify problems and their causes, the corresponding improvements. The main conclusions are as follows:1. Gansu Province, the average male hockey players training in a shorter period (5 years), initial training older (16.3 years).2. Gansu Province, strong men's field hockey players body, muscle symmetry, shoulder width, the overall hockey program in line with the body shape specifications.3. Men's hockey players in Gansu Province in early speed of the ball an instant a small, behind the foreign athletes, is the success rate of the main reasons for the short corner.4. Men's hockey players in Gansu Province after the tread on the step phase angle is too large, cross-stage on the step angle was too small to affect the horizontal velocity is the direct cause of the initial velocity of the ball also contributed to the slow indirect causes. Anaerobic Power shortage and the weakness of the ankle is caused by a large angle of the ground after kicking the reasons for the small angle.5. Men's hockey players in Gansu Province joint angle, flip angle is too small shoulder caused by inadequate equipment beyond the impact to the final out of the ball speed. Waist joint angle of force is the main reason for the size of his right shoulder too early have the shoulder angle is caused by a small flip technical reasons.6. Support of Gansu Province technological gap hockey players left, right shoulder forced prematurely, affect the final force, and quality aspects of lower limb explosive power and strength of the core area of less than all affect the final out of the ball speed. |
