Purpose: The purpose of this study was to explore the critical skills required for volleyball to win in World League Volleyball Game. Methods: The 212 games of the World League Volleyball in the year 2007 and 2008 were used in this study. In each game, the Federation Internationale de Volleyball provided official match statistics that include the result of the game (win or lose), attack, block, serve, dig, set and receive. Data were analyzed using description statistics to know percentage of volleyball skills performance successful. Pearson's correlation analysis was used to analyze relationship between percentage of volleyball skills performance successful and scores. Discriminate analysis was used to find critical volleyball skills. Results: The results are as follows: 1. Successful percentage of volleyball skills in attack, block, serve, dig, set and receive were 0.84, 0.58, 0.83, 0.68, 0.99 and 0.94. The winners performed successful percentage of attack, block, serve, dig and receive better than losers in games. 2. Performance successful percentage of dig and receive had positive correlation with spike scores. The skills of attack, serve and block had positive correlation performance successful percentage and scores. The skill of loss scores had negative correlation with performance successful percentage of the skill of spike and serve. 3. Performance successful percentage of attack, block, serve, dig, set and receive were significant impact to win volleyball game in World League. Conclusion: Consequently, performance successful percentage of spike, block, serve, dig, set and reception were critical factors to win volleyball game in World League.
