The goal of the present study was to understand the effects of the block positions on the various aspects of score performance. Each game was videotaped, and analyzed by statistics in terms of the block position 2, 3, and 4. The investigated performance included single or combinational attacks, scores, and loss. This helped to understand the factors associated with block position that affects score performance. The information can be used for future training. The results are as follows. (1) ANOVAs using F-tests showed that there were no significant differences among positions in the individual scores/losses, combinational scores/losses, and total scores/losses. (2) Pearson’s correlation tests showed that, the times of blocks in the position 2, 3 and 4 were correlated with the total scores. (3) Regression analysis showed that, the total score was fully predicted by the combinational scores of position 2 and 4. 83.1% of the total score can be explained by the regression model. In particular, the combinational score at position 4 contributed 55.1% of the explainability. The results suggest that good cooperation and teamwork plays an important role in the total score, which can be improved by clear judgment, prediction, and proper anchor takeoff. Position 3 is relatively weak at blocking, which may be improved by specific training in the future. In addition, if the times of block can be increased at the position 2 and 4, it may also result in better performance in the games.
