As subjects of university soccer players, to examine kinetic variables of body segments on impact in impact shoot from the goal forward to the right corner in soccer, the result of analysis by using three dimensional cinematographic equipment and force-platform is as follows. 1. The taking time to the impact point in shoot motion represented 0.09 second. 2. The distance between the support foot and the ball in impact for the X and Y axes presented 0.445m and 0.140m, respectively. 3. The degree of angle for the shoulder rotation, upper back and forth slope, trunk side slope, hip rotation, hip slope, hip-,joint, and knee-joint in impact were 29.22。 , 5.15。 , 5.73。 , 9.74。 , 14.32。 , 126.63。 and 135.80。 , respectively. 4. The velocity for the C.O.G, hip-joint, knee-joint, and ankle-joint in impact were 3.83m/s. 3.llm/s. 6.16m/s and 13.34m/s, respectively. Immediately after the impact, the maximum ball velocity was 24.03m/s. 5. The C.O.G displacement for the X, Y, and Z axis in impact represented 1.44m, 1.56m and 0.89m, respectively. 6. The absolute angular momentum of all over the body in impact was 8.99 kg m^2 /s. 7. The ground reaction force in impact for the left side ( Fx ) , back side ( Fy ) , and vertical side(Fz) acted -198.16N,-552.48N, and 1,581.76N, respectively.
