In order to investigate ways to improve the basic techniques of beginners, the motions of forehand strokes in Table Tennis are analysed by 3 dimensional analysis using the DLT method. 6 male subjects participated in this study. 3 subjects were trained and 3 were untrained. Subjects hit the balls towards a hitting point on the opposite side of the court. The hitting motions were recorded by 2 synchronized video cameras. Stick pictures from views of the X axis, the Y axis, Z axis and other axers were derived by a 3 dimensional method. The results obtained are as follows; Trained players tend to move their wrist more efficiently, with pinching knee and elbow, shoulder and twist movements being quick and keen during the forehand smash stroke than that of untrained players. It is suggested that one way to improve the basic techniques of beginners is to move each parts of the body of forehand strokes gracefully.
