This final paper investigates the relationship between the quality of volleyball service and performance in the Women's Italian Volleyball Superleague. A total of 1929 matches played over 12 seasons were analyzed, spanning from the 2010/11 season to the 2022/23 season. The 2019/20 season was excluded due to the COVID-19 pandemic. The subjects of the study were clubs categorized based on their placement at the end of each season. The analysis involved four variables related to the quality of service: the total number of serves per set (SU/set), the total number of points scored through serves per set (S#/set), the total number of service errors per set (S=/set), and the total number of serves that led to continued play per set (SO/set). The results indicated statistically significant differences in service quality between different placements, with the top-ranked teams exhibiting higher-quality volleyball serves. Furthermore, a statistically significant correlation between service quality and placement was established, with better serves being associated with higher placements. Although differences in service quality fluctuated throughout the seasons, no statistically significant difference in the overall trend was identified. However, certain seasons showed significant variations in specific variables. These findings suggest that the quality of volleyball service is important for achieving better placement in the Italian Volleyball Superleague. This final paper provides valuable insights to clubs and coaches regarding the significance of developing service skills to enhance their league standings.
