The purpose of this study was to investigate the tactics of the spike by intemational-class volleyball players. Chinese, Korean, and Japanese male players who participated in the 1994 Asian Games and the 1994 Nippon Volleyball League Final Games held in Hiroshima were filmed at 100 f. p. s. with two 16mm cinecameras and a VTR. 38 successfully perforτned spikings were selected for the analysis. 22 three dimensional coordinates for the segment endpoints and a ball were computed by the Direct Linear Transformation Method.
The results were summarized as follows: The rate of simultaneous attacking by three to four spikers was much larger (84.3%) than that of attacking a outside high set from backcourt (12.9%). The left frontcourt spike was often used simultaneously with the backcourt spike-from right-side area. The average maximum height of each set was 4.18, 4.34m respectively. Besides being broadjumpping, quick spiker hit the set whose average length was 1.15m.
