Sažetak
This study aimed to evaluate a specific model of evaluation of cadet players’ performance in water polo. The participants in this study were 61 young water polo players, members of Croatian and Montenegrin teams (15-16 years of age). Variables included six indicators of specific water polo performance. Three water-polo experts independently evaluated each subject on all performance-indicators using a scale from 1 to 5. Coefficient of variation (CV) and intra- class- coefficient (ICC) were calculated for reliability of the evaluation for performance- score. Discriminative analysis and t-test were used to determine discriminative validity of the applied system of evaluation of specific water polo performance. The reliability of the offensive and defensive performance-indicators showed appropriate ICC values from 0.71 for agility- offense up to 0.81 for agility-defence and CV values showed relatively small within- subject variations. Independent- sample t-test, and discriminative canonical analysis showed significant differences between qualitative groups of players (starters vs. nonstarters) for observed performance-indicators. Investigation confirmed appropriate reliability and applicability of proposed method aimed at evaluation of water polo performance in offensive and defensive tasks.
