AI Article Synopsis
- Home advantage (HA) in volleyball is significant, showing a winning probability of 57.01% for men and 55.39% for women when playing at home, indicating a strong influence of location on match outcomes.
- Research focused on small female sample sizes has overlooked the effect of spectators, prompting this study which analyzed 25 seasons of professional German volleyball, totaling 6,833 matches for both genders.
- The presence of more spectators had a minimal impact on winning chances, and unlike other sports, HA has not shown significant development over the years.
Article Abstract
Home advantage (HA) regularly occurs in volleyball (Pollard et al., 2017: men: 56.62%, women: 55.26%). Research to date has investigated primarily small samples of mostly female matches and not looked into the potential impact of spectators on HA. This archival analysis uses multilevel modelling to examine HA in professional German volleyball (men & women) over 25 seasons in all regular and play-off matches (N = 6,833). We analyze how spectators drive HA and whether this projects to the COVID-19 season 2020/21. When intercepts varied between teams (2-level model, ICC = 27%), the winning probability increased when playing at home (men: 57.01%, OR = 2.39, d = 0.48; women: 55.39%, OR = 2.19, d = 0.43), while controlling for team strength, interaction with gender, and travelling distance. More spectators had a negligible effect on the men's and women's chances (|d| < 0.07). Similar trends were observed for the probability of winning sets. Contrary to other team sports (e.g., soccer), there is no HA-development over the last decades.
