This study investigated the relationship between performance and height, body composition, reaction time,
and executive ability (Design fluency test: DFT) in elite female players of 9-player volleyball. Furthermore, we
compared the aforementioned elements among different player positions (i.e., attackers, setters, and receivers). A total of sixteen female volleyball players (with an average age of 24.2±1.97 years) from the V9 Champ League 2023 participated in this study. We measured the height, body composition (weight, body fat, and muscle score), reaction time, and DFT of each player. We calculated the Individual ratio (IR) as a performance score based on their performance during scrimmages. Our results revealed a negative relationship between individual ratio and body fat. A comparison between the positions revealed that attackers and setters were significantly taller than receivers, attackers were significantly heavier than setters and receivers, the muscle score in receivers was significantly higher than that in setters, and the IR in setters was significantly higher than that in receivers. Although the difference was not significant, we observed a marked effect size in body fat-related differences. Setters had lower body fat content than attackers and receivers, and the DFT-T score, which is the total number of correct answers across all three tests of the DFT, was lower in attackers than in setters and receivers. In conclusion, body fat should be monitored to maintain high performance, particularly in setters. Finally, higher muscle quality would be beneficial for improving the performance of receivers.
