BIOMECHANICAL RESEARCHES ON TAKE-OFF OF LONG JUMP (REVIEW)
AbstractPURPOSE AND METHODS Biomechanical research on the takeoff of the long jump were classified and summarized in the view of kinematics and dynamics. The indexes of kinematics included angle stepping on the board, stride Length of the three or four steps before stepping on the board, time of takeoff. The indexes of dynamics mainly included the vertical force obtained on the platform dynamometer. The kinetic characteristics in buffering, driving and other phases in the process of takeoff were summed up in detail. The indicator of the center of pressure was used in examining different takeoff skills.
