Background: Volleyball is a team sport that requires a lot of movement and explosive movement. Volleyball players have different roles depending on their position. The reason is that the spiker or center is tall and the libero or setter is relatively small compared to other positions. Objectives: To investigate a difference in basic physical fitness according to the positions of volleyball players and to examine the correlation between basic physical fitness items. Design: Correlational research designs. Methods: A total of 33 male professional volleyball players were recruited for each position by position: 15 spikers, 7 centers, 5 setters, and 6 liberos. Muscle endurance, power, agility, and balance ability were measured as basic physical fitness items. Results: There was a statistically significant difference in agility according to each position (P<.05), and a positive correlation was indicated in muscle endurance and power (P<.05). Conclusion: A training program can be developed based on the correlation between training and basic physical fitness according to the positions of volleyball players.
