Aim: The main aim of the study was to analyze the differences in Home Advantage (HA) and Win Percentage at Home (HW). A secondary objective was to analyze how team ability might modify the HA effect by comparing the interaction between the HA effect and the team ability effect in both fans games and games played without fans. Methods: Data was collected from first Spanish female Basketball Divisions. Linear mixed model (LMM) for repeated measures was used to identify differences between period (fans vs without fans) for HA and HW. Results: When comparing games with and without fans, no significant differences were found in both HA and HW (p = .283 and p = .872, respectively). Interestingly, higher values were observed when fans were absent from the stadiums. Additionally, during the pandemic stage, HA increased, but it returned to pre-pandemic levels afterward, with no significant differences (p = .482). Similarly, HW increased during the COVID period and seems to continue improving in the post-pandemic phase, but again, no significant differences were found (p = .772). Conclusions: Higher HA and HW were shown without fans during the pandemic compared to pre-pandemic games with fans in women’s professional basketball. Additionally, During Post-pandemic period, HA decreased upon fans’ return, while HW continued increasing.
