Study On The Application Of Video Panorama Technique In Women's Pole Vault Project

Pole vault is a very complicated field event in track and field.It has a strong technical skill and good technical action plays a decisive role in achieving excellent results.Taken the 13 th national games qualifier and the 13 th national games,women's final scores highest successful jump technical features as the research object,adopting the method of shooting video analysis,mathematical statistics,from the perspective of special technology to explore our country outstanding female pole vaulter run-up,take-off techniques and support phase time rhythm,analysis and contrast technical characteristics between China's international elite level and master sportsman athletes group,providing a theoretical basis for optimizing the pole vault project and improve the training.Research purposes: Using video panorama technology acquisition and analysis of domestic and international level pole vault athletes,analysis and discuss the relationship between the indexes,in order to improve women's pole vault project sports technical ability and the level of development to provide advice.Research method: Camera photography;Video panorama analysis method;Comparative analysis;Mathematical statistics.Conclusions:In terms of width of grip distance parameters,the international elite group is much longer than the master sportsman group and has a significant positive correlation with the results.Step length,the gap between our country athlete penultimate and last step is not obvious,but the step length difference of elite group is longer than sub-elite group and exist significant difference.In terms of time parameters,there was no significant difference in the starting time between the two group,and the time difference between the jump time and the jump time was significantly positive.During the supporting stage,the time difference and change of Chinese athletes in the supporting stage are not big,and the total time of achievement and supporting stage is not significantly correlated.There was a significant negative correlation between the long pendulum stage and the short pendulum stage,both in terms of time and percentage of time.The international athletes are better than the athletes in the time allocation of the push rod stage.In terms of the speed parameters,the three steps of the elite group were all greater than that of the sub-elite group,and the difference of the mean of the walking speed of the two groups are significant.In addition,the loss of the final step of the elite group is less than sub-elite group.In terms of Angle parameters,there is difference between two groups in takeoff time,can also be appropriate reduce takeoff Angle,better use of horizontal velocity and improve the results of the competition.It is the main reason for the difference between the Angle of the grip and the Angle of the jump moment.In China,the overall average of athletes' trunk Angle is better,but the difference is more obvious.The elite group is better than thesub-elite group,but the stability is poor.
