The purpose of this study was to analyze the motion of standing long jump performance of elementary school children. The 82 boys of school children (6-11yrs) performed standing long jump, and was measured the distance. The motion of the body segments were recorded and analyzed the shoulder, hip and knee joints using a 2-D video analysis system. As a result, values of the range of joint angle, the average angular velocity of the shoulder were increased with aging. A coefficient of correlation with the jump performance was higher in the shoulder joint of angle, range motion and the average angular velocity than those of the hip and knee joints. The hip and knee joint angle at the landing moment, the range of the hip and knee joints in diving down stage decreases from the first grade to the third grade. The average angular velocity on the hip and knee joints increases from the first grade to the third grade both in bent-down and take-off stages. Depending on the various developments, we should introduce suitable methods to teach elementary school children the standing long jump movement.
