With the objective of clarifying which performance indices are correlated with the outcome of the game for attacks following serve-reception in international men's volleyball tournaments, this study analyzed the 2015 Volleyball Men's World Cup. The results obtained are as follows. (1) Considering all attacks when in-system, and using each team's percentage of winning the set as the variable, very strong positive correlations were confirmed for the attack efficiency (r =0.948, p <.001) and kill attack percentage (r =0.902, p <.001). (2) Considering quick attacks when in-system, and using each team's percentage of winning the set as the variable, a very strong positive correlation was confirmed for the attack efficiency (r =0.787, p <.01) and kill attack percentage (r =0.711, p <.01), and a relatively strong negative correlation was confirmed for the percentage of losing points from an attack (r =-0.582, p <.05). (3) Considering pipe attacks when in-system, and using each team's percentage of winning the set as the variable, very strong positive correlations were confirmed for the kill attack percentage (r =0.876, p <.001) and attack efficiency (r =0.784, p <.01), and a relatively strong positive correlation was confirmed for the attack attempt percentage (r =0.629, p <.05). (4) Considering front side attacks when out-of-system, and using each team's percentage of winning the set as the variable, a relatively strong negative correlation was confirmed for the blocked attack percentage (r =-0.606, p <.05).From the above, it became clear that in terms of attacks following serve-reception at the 2015 Volleyball Men's World Cup, in-system attacks are correlated with the outcome of the game, especially with correlations found in the potency and accuracy of quick attacks, and the potency and frequency of pipe attacks. In addition, it was confirmed that for out-of-system front side attacks, the points lost due to being blocked by the opponent had a correlation with the outcome of the game.
