The purpose of this study was to analyze and compare with the kinematic characteristics of the skilled and unskilled players on heading shooting in soccer. with the three-dimensional cinematography. The subjects of this study were six high school football players as a skilled player and five high school students as a unskilled player who didn't have any experience in football. They were asked to head the ball which was hanged from the ceiling and moving like a pendulum. They were asked to head the ball to the direction of front and ninety degree. To analyze heading movement, an image data, called Arial Performance Analysis System(APAS), produces the value of coordinates, then finally the data were analyzed by LabView 6i. It was performed by independent t-test to identify the significant differences between the skilled and unskilled players.The result of this study were as follows:1. The time parameter for the total phases didn't show the significant difference between the skilled and unskilled players but, the time of the phase of impact was showed the significant difference.2. As heading to the direction of front, the angle of the head was showed the significant difference in the maximum extension angle, flexion angle and the impact point3. As heading to the direction of ninety degree for the anterior and posterior, the angle of the head was showed the significant difference in the range of motion.4. As heading to the direction of front, the angle of the trunk was showed the significant difference in the maximum extension angle, flexion angle and the impact point5. As heading to the direction of ninety degree for the anterior and posterior, the angle of the trunk was showed the significant difference in maximum extension, maximum flexion angle and impact point, for the left-right flexion the angle of the trunk was showed the significant difference in the maximum left flexion angle and impact point, for the outward rotation the angle of the trunk didn't show the significant difference in the angle of outward rotation, range of motion and impact point.
