Purpose: Analysis of short game kinematics of low and high-handicap golf lovers. Methods: Golfzon has been adopted to capture data of 100, 80, 60 and 40 yard ball distances, flight and running distances, emission angles, sin 2α, ball speed, theoretical horizontal distances, surplus distances, directions, golf club loft angles and left or right distances to the hole to discuss kinesiological differences of low and high-handicap golf lovers. Result: Data of low and high-handicap groups obtained from Golfzon indicated that the control of average surplus distance and distance of the low-handicap group is better than the high group. No matter the distance after golf balls hit out, the running distance is about 5-8 yards. That is, to be closer to the hole, balls should land about 5-8 yards before the pole. As to hit for a shorter range, ball speed becomes slower. Comparing calculated data from projectile movement formula, data of theoretical horizontal distance is smaller than actual flight horizontal distance. It is because of the loft is not zero as the club head hit the ball. Conclusion: As there is a good match of ball speed and emission angle, the low-handicap group easily reached the goal with less effort to strike a ball, whereas the high-handicap group is opposite.
