(ES = 0.59, _moderate effect_; \(\Delta\) = 5.9%); defenders vs. midfielders in CMJ (ES = 0.28, _small effect_; \(\Delta\) = 4.4%) and SJ (ES = 0.36, _small effect_; \(\Delta\) = 3.4%), vs. forwards in CMJ (ES = 0.64, _moderate effect_; \(\Delta\) = 9.11%) and SJ (ES = 0.32, _small effect_; \(\Delta\) = 3.0%); and midfielders vs. forwards in CMJ (ES = 0.33, _small effect_; \(\Delta\) = 4.9%) and SJ (ES = 0.88, _large effect_; \(\Delta\) = 6.2%). However, in DJ, there were statistically significant differences between groups (F\({}_{(3,96)}\) = 20.8; \(p\) = 0.000): comparing midfielders vs. goalkeepers (\(p\) = 0.00; ES = 1.59, _large effect_; \(\Delta\) = 9.2%), vs. defenders (\(p\) = 0.00; ES = 1.21, _large effect_; \(\Delta\) = 25.1%); and vs. forwards (\(p\) = 0.00; ES = 1.73, _large effect_; \(\Delta\) = 16.3%), showing a greater jump height in favor of midfielders, but no significant differences were recorded when comparing goalkeepers vs. defenders (ES = 0.41, _small effect_; \(\Delta\) = 5.1%), goalkeepers vs. forwards (ES = 0.39, _small effect_; \(\Delta\) = 4.6%), or defenders vs. forwards (ES = 0.04; \(\Delta\) = 0.4%). Similarly, in the 10 m, 20 m, and 30 m sprints, there were no significant differences in 10 m (F\({}_{(3,96)}\) = 2.94; \(p\) = 0.30), 20 m (F\({}_{(3,96)}\) = 1.50; \(p\) = 0.21), or 30 m (F\({}_{(3,96)}\) = 0.21; \(p\) = 0.88): comparing goalkeepers vs. defenders in the 10 m sprint (ES = 0.06; \(\Delta\) = 1.1%), 20 m sprint (ES = 0.18; \(\Delta\) = 2.1%), and 30 m sprint (ES = 0.04; \(\Delta\) = 0.5%), vs. midfielders in the 10 m sprint (ES = 0.54, _moderate effect_; \(\Delta\) = 9.1%), 20 m sprint (ES = 0.32, _small effect_; \(\Delta\) = 3.6%), and 30 m sprint (ES = 0.67, _moderate effect_; \(\Delta\) = 9.7%), vs. forwards in the 10 m sprint (ES = 0.35, _small effect_; \(\Delta\) = 6.5%), 20 m sprint (ES = 1.75, _large effect_; \(\Delta\) = 2.5%), and 30 m sprint (ES = 0.56, _moderate effect_; \(\Delta\) = 8.4%); defenders vs. midfielders in the 10 m sprint (ES = 0.48, _moderate effect_; \(\Delta\) = 8.1%), 20 m sprint (ES = 0.08; \(\Delta\) = 1.4%), and 30 m sprint (ES = 0.62, _moderate effect_; \(\Delta\) = 8.2%), 20 m sprint (ES = 0.03; \(\Delta\) = 0.3%), and 30 m sprint (ES = 0.52, _moderate effect_; \(\Delta\) = 7.8%); and midfielders vs. forwards in the 10 m sprint (ES = 0.15; \(\Delta\) = 2.9%), 20 m sprint (ES = 0.09; \(\Delta\) = 1.1%), and 30 m sprint (ES = 0.08; \(\Delta\) = 1.4%). In ball-kicking speed with the dominant foot, significant differences were observed between the groups (F\({}_{(3,96)}\) = 5.84; \(p\) = 0.001): comparing goalkeepers vs. defenders (\(p\) = 0.02; ES = 0.99, _large effect_; \(\Delta\) = 8.8%), vs. midfielders (\(p\) = 0.00; ES = 1.21, _large effect_; \(\Delta\) = 11.8%); and vs. forwards (\(p\) = 0.04; ES = 0.40, _small effect_; \(\Delta\) = 7.8%), with goalkeepers showing a lower ball-kicking speed with their dominant foot compared to the other positions. In contrast, no significant differences were reported when comparing defenders vs. midfielders (ES = 0.44, _small effect_; \(\Delta\) = 2.7%), vs. forwards (ES = 0.05; \(\Delta\) = 0.8%); or midfielders vs. forwards (ES = 0.48, _small effect_; \(\Delta\) = 3.5%). Significant differences were recorded in ball-kicking speed with the non-dominant foot between groups (F\({}_{(3,96)}\) = 3.29; \(p\) = 0.02). Comparing goalkeepers vs. midfielders (\(p\) = 0.01; ES = 0.81, _large effect_; \(\Delta\) = 7.6%), goalkeepers showed a lower ball-kicking speed in their non-dominant foot. Meanwhile, no significant differences
