Significant small correlations were found between session-RPE and sleep duration after matches (r = 0.233, 95% CI (0.039;0.411); \(p\) = 0.020), total distance and quality of sleep after training (r = 0.198, 95% CI (0.001;0.379); \(p\) = 0.049), distance at Z1 and quality of sleep after training (r = 0.220, 95% CI (0.025;0.400); \(p\) = 0.028), distance covered at Z5 and quality of sleep after training (r = 0.286, 95% CI (0.095;0.456); \(p\) = 0.004), session duration and rested feeling after training (r = 0.227, 95% CI (0.032;0.405); \(p\) = 0.023), total distance and rested feeling after training (r = 0.202, 95% CI (0.006;0.383); \(p\) = 0.044), distance covered at Z3 and rested feeling after training (r = 0.222, 95% CI (0.026;0.401); \(p\) = 0.027) and distance covered at Z5 and rested feeling after training (r = 0.214, 95%CI (0.018;0.394); \(p\) = 0.032). \begin{table}
