The kinematic variables of the squash backhand drop shot were analyzed through a three-dimensional cinematography. The displacements and velocities of trunk and racket, and the angular displacements and velocities of elbow and shoulder joints were compared between the expert and novice groups. The results were follows. First, The lap time of the expert group was longer than that of the novice group. Second, X(anterior-posterior), Y(vertical), and Z(lateral)-axis racket displacements of the expert group were significantly higher than those of the novice group during the DS(down swing) period. X(anterior-posterior)-axis racket displacements of the expert group during the FT(follow through) period was shown to be maintained longer in forward direction. Third, Racket speed of expert group was significantly lower than that of the novice group. Forth, the elbow joint angle of the expert group was maintained longer after the impact than the novice group. Fifth, the expert group showed elbow extension just prior to the impact while the novice group showed impact with pre-extended elbow joint. As a final conclusion, the racket should move fast during the down-swing period and move slowly during the follow-through period, and the shoulder joint should extend prior to the elbow joint extention for the efficient squash backhand dropshot motion.
