## 3 Results  
The ANOVA revealed significant differences (\(p\) < 0.05; ES > 0.5) between periods for Player 4, Player 5, Player 8, Player 10, and Player 11 in the A\({}_{0}\) averages (Table 1) and for the Player 3, Player 6, Player 8, Player 11, Player 13, and Player 14 in the S\({}_{0}\) averages (Table 2) (all parameters per player and team analysis derived from ANOVA are added as Supplementary Material--Table S1). [PERSON]'s test showed significant differences (\(p\) < 0.05) in A\({}_{0}\) and S\({}_{0}\) averages between In 2 and other periods for Player 4 (Pre 1, In 1, In 3 and Pre 2) and Player 8 (In 1 and In 3) (Table 1) and for Player 6 (In 1 and Pre 2) and Player 8 (In 3) (Table 2), respectively. Additionally, SD showed small to moderate intra-player variability for all players (SD range from \(\pm\)0.22 to \(\pm\)0.69) in the A\({}_{0}\) averages (Table 1) and for most players (SD range from \(\pm\)0.27 to \(\pm\)0.90) in the S\({}_{0}\) averages (Table 2). Inter-player variability was higher in Pre 1 and In 2 (SD = \(\pm\)0.58 and \(\pm\)0.61, respectively) for A\({}_{0}\) (Table 1) while it remained stable (SD range from \(\pm\)0.53 to \(\pm\)0.61) during all periods for S\({}_{0}\). Players out of SD ranges for A\({}_{0}\) and S\({}_{0}\) for all periods are shown in Figure 3.
