Figure 4: The average POMS scores across the 16 matches for non-injured (n = 15) and injured players (n = 6). Figure 5 shows that the injured group has greater mood variability in all POMS factors except depression. Notably, the TMD index shows greater stability in players without injuries. In Table 8, the coefficient of variation scores across the 16 matches and the analysis of mean differences using the Mann-Whitney U test for the CSAI-2 factors according to injury presence or absence are shown. It is observed that the mean coefficient of variation values are similar between injured and non-injured players, with a slightly higher variability in self-confidence for the injured group. However, statistical analyses indicate that the occurrence of injury was not significantly influenced by the stability of these psychological variables. \begin{table}

Table 7: Differences in the coefficient of variation scores of the POMS over the average of 16 matches between non-injured (n = 15) and injured (n = 6) players. Figure 5: POMS variability scores over the average of the 16 matches between non-injured players (n = 15) and injured players (n = 6). Additionally, Figure 6 shows greater dispersion in the total CSAI score in the group with injured players compared to the non-injured group. Concerning the relationship between the two constructs (POMS and CSAI-2), Table 9 shows high to moderate correlations among the five POMS factors, with rho coefficients ranging from \(-\)435 (\(p<0.05\)) to 0.940 (\(p<0.001\)). The Total Mood Disturbance (TMD) index exhibits very strong or strong positive correlations with four of these factors, namely tension (rho = 0.668; \(p<0.001\)), depression (rho = 0.920; \(p<0.001\)), anger (rho = 0.655; \(p<0.001\)), and fatigue (rho = 0.937; \(p<0.001\)), and a significant negative correlation with vigor (rho = -.624; \(p<0.01\)). \begin{table}
