    Abstract

    Recently, video footage has been used for motion observation of primary players for sports instruction. In this paper, we analyze motion observation of an expert javelin thrower at several frame rates of attempt movie. We obtained an interview with an expert javelin instructor to investigate the effectiveness of high speed movies on motion observation with frame rates of 30, 60, 120, and 240 fps. As a result, (1) playback times, (2) pause times, (3) fast-forward or rewind times, and (4) playback order were measured. In addition, 57 of the meaningful units for instruction were obtained from the interview analysis. The results also show that the high speed movie is effective for figuring out a player's conscious of bodymotion and setting an agenda to adjust motion in dynamic postures for motor learning. The differences of the tendency of motion observation between each frame rate were also discussed.
