The Kinematics Research For The Domestic And Foreign Professional Basketball Player Of Shaanxi By Stop-shot

In this paper, through experimental and image analysis method, we used high-speed camera film lithium power to simulate real combat situations of Shaanxi liyuan basketball players and foreign players in the same team .The technical movements that teammates cover off moving step up, stop and rush shoot ball by using APAS (Ariel performance analysis system) on the images collection parse. We can get the raw data of the technical movements in all phrases for statistical analysis from the original image by a scientific and reasonable clip and other locations, smooth. Analyzing the raw data by the use of mathematical statistics and comparing the original data of Chinese players and foreign players, then all the advantages and disadvantages are found. Through quantitative analysis to identify the root causes of the differences, advantages and disadvantages between the various players and trace the points of the law and potential action for the trip to catch passes jumper. This may provide reference and basis for future training to improve my basketball training and technology.Final results show that throughout the course of step in the trip to catch passes, the Chinese players do better than the foreign players in the speed and height of jumping off ; But completed action spends more time than foreign players do and the velocity of last shot is smaller than foreign players'; The process of moving at foot brake to catch the instantaneous center on foot, vertical velocity and low gravity for takeoff effect has greater impact; In the ground buffer stage, the Chinese players are faster than foreign players in knee buffer and squat focus is faster than foreign players too; In kicking off phase, the time used by the Chinese players is shorter than foreign players'; The arms of Chinese players at takeoff play a larger role than foreign players'. Lower extremity hip and ankle joint angular velocity is smaller than the foreign players' while ankle angular velocity is larger than foreign players'; During vacated shot phase, the shot time of Chinese players is later than the foreign players' and the speed is slower.
