| Abstract: | With document information,high speed camera and computerized film analyses,comparative analysis,etc.for Liu Xiang in the 110m hurdle twice the match the analysis of the 5th attack into the hurdle technology to analyse,and with its same site sports the hurdle player some technical parameter of 110m compare comparatively.It has been shown that:From Liu Xiang's the 5th of 110m hurdle,the takeoff and attack into the hurdle consciousness,is strong;the landing angle,is larger;the support time,is short;the takeoff angle,is less to attack into the hurdle speed,is rapid;the takeoff angle of bady's center of gravity,is little.It accords with this event kinematic feature and the present world technical development of the 110m hurdle race tendency. |
