### Effect of Refreeing Technique and Competition Sex in Workload Demands by Game Quarter  
Figure 3 shows the internal and external workload demands by game quarter based on the refereeing technique and sex of players in basketball games. Q1 showed significant differences between groups in most external variables. Total distance revealed significant differences (\(F\) = 27.30, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.48 large), with high-intensity distance (>16 km/h) also showing notable variations (\(F\) = 23.60, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.44 large), mainly between 2-referee teams and 3-referee teams, with a very-large-to-large effect size. For acceleration metrics, \(\text{Acc}_{\text{MAX}}\) displayed differences (\(F\) = 4.08, \(p\) = 0.009, \(\omega_{p}\)\({}^{2}\) = 0.10 moderate) between 2 Refs-female and 3 Refs-male and between 3 Refs-male with moderate effect, while \(\text{Dec}_{\text{MAX}}\) showed variations (\(F\) = 6.53, \(p\) = 0.001, \(\omega^{2}\) = 0.16 large) between 3 Refs-male and other groups with a moderate effect size. Both \(\text{Speed}_{\text{AVG}}\) (\(F\) = 17.40, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.36 large) and \(\text{Speed}_{\text{MAX}}\) (\(F\) = 4.55, \(p\) = 0.005, \(\omega_{p}\)\({}^{2}\) = 0.11 moderate) demonstrated differences, with Player Load also showing significant variations (\(F\) = 8.31, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.20 large) primarily between 2-referee teams and 3 Refs-male teams with large-to-moderate effect sizes. Q2 maintained similar patterns but with generally lower effect sizes. Total distance continued showing significant differences (\(F\) = 15.60, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.34 large), as did high-intensity distance (\(F\) = 15.90, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.34 large). \(\text{Acc}_{\text{MAX}}\) and \(\text{Dec}_{\text{MAX}}\) showed no significant differences during this quarter. \(\text{Speed}_{\text{AVG}}\) maintained significant differences (\(F\) = 7.90, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.19 moderate), while \(\text{Speed}_{\text{MAX}}\) showed limited differences (\(F\) = 2.93, \(p\) = 0.039, \(\omega_{p}\)\({}^{2}\) = 0.06 moderate) only between 2 Refs-male and 3 Refs-female (moderate effect). Player Load showed moderate differences (\(F\) = 4.20, \(p\) = 0.008, \(\omega_{p}\)\({}^{2}\) = 0.10 moderate) between 2-referee teams and 3 Refs-male teams. Q3 presented the highest effect sizes in several variables. Total distance showed the largest effect size (\(F\) = 39.30, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.57 large), with significant differences between all groups, and high-intensity distance maintained significant differences (\(F\) = 22.10, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.42 large). While acceleration variables showed limited differences, \(\text{Dec}_{\text{MAX}}\) presented some variation (\(F\) = 3.25, \(p\) = 0.026, \(\omega_{p}\)\({}^{2}\) = 0.07 moderate) between 2 Refs-female and 3 Refs-male (moderate effect). \(\text{Speed}_{\text{AVG}}\) showed strong differences (\(F\) = 23.40, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.44 large), and Player Load displayed significant variations (\(F\) = 14.10, \(p\) < 0.001, \(\omega_{p}\)\({}^{2}\) = 0.31 large) between 2-referee teams and 3-referee teams. Figure 3: Internal and external workload dynamics throughout the game quarters based on the refereeing technique and the sex of the competition. Q4 maintained significant differences but with generally lower effect sizes compared to previous quarters. Total distance (\(F^{2}\) = 13.40, \(p\) < 0.001, \({\omega_{p}}^{2}\) = 0.30 large) and high-intensity distance (\(F\) = 17.70, \(p\) < 0.001, \({\omega_{p}}^{2}\) = 0.37 large) continued showing differences between groups. Acceleration metrics showed no significant differences, while Speed\({}_{\text{AVG}}\) maintained strong differences (\(F\) = 14.70, \(p\) < 0.001, \({\omega_{p}}^{2}\) = 0.32 large).
