Abstract

The purpose of this study is to analyze the kinematic analysis of the last three strides and take-off motion in the actual competition of the men`s long jump. Five long jumpers who has been registered in the Korea Athletic Federation were involved in this study as subjects. The conclusions were as follows: 1) For the skilled long jumpers, it took shorter time than the less-skilled long jumper during the take-off motion and from the last three strides to the take-off motion. 2) The better record players began to low CM at the last three step before take-off, showed the lower CM in 1-2 step phases before touch down the board and increased the CM at take-off the board. 3) The better record players showed the shorter stride length and horizontal distance at last three step. 4) The horizontal velocity in the approach deaccelerated at the take-off phase. 5) For effective take-off motion, the player should decrease the last step at touch-down the board and the hip and knee angle as small as possible, and lean the body to backward, decrease. And to increase the impact on touch down board, the player should decrease the touch down angle of foot as small as possible, and touch down the board with whole sole of foot. 6) The thigh should quickly increased the angular velocity of hip joint which plays in increasing propellent toward CM at touch down and take off the board. Esp eciaiiy, the large angular velocity caused by the fast flexion and extention should lead the effective airborne motion with having the high CM due to the fast extended propelling leg to forward.
