The competition of Gymnastic has a skill called Flic-Flac. This skill starts from errect posture, and by the thrust of the feet from the backward to upward direction, and then touch with the hands on ground and leave with the hands to landing on ground with feet. Flic-Flac is a skill commonly seen in the Floor Exercise from long time ago, but it become a skill of the Balance Beam was quite resently after the Mexico Olympic 1968. Today the Flic-Flac is a basic part of series movements in Balance Beam. For the purpose of instruction, we used 16mm cinecamera to filming the movement Flic-Flac, and compared it with one which was done on the Floor and the other was on Balance Beam ten healthy subjects (two Elementary School girls, three Junior High School girls, three High School girls, and two University girls included) were voluntary perticipated in this study. Some interesting findings from comparing both performed on Floor and on Balance Beam can summarized as follows ; (1) The horizontal distance from start to the finish was different. (2) The movement of limbs and frunk diffly were found. (3) The locus of movement were different. (4) The toe toward Balance Beam quicker. (5) The way to carry out this movement were differ from one to another from the subjects. (6) The less variation of movement found in some subjects have better posture achievement in performing Flic-Flac. As the height and width of the Balance Beam is limited, so from the time of start down to the time of take off is better exerted by the use of knee and waist. From the view point of instruction its thought to begin from Floor, and then gradually raisen the height of Balance Beam from low up to the normal height for achieving better sooner.
