| Popis: | This study aimed to evaluate the validity and reliability of a water polo video-based test to assess decision making. Ninety-five female and male elite/tier 4 (T4) or highly trained/tier 3 (T3) athletes participated using their smartphones. Males repeated the test one week later for reliability analyses. Coaches assessed males’ in-water decision making and females were noted as selected or nonselected for the national team. Although response accuracy was significantly different between T3 and T4 athletes ( p s(88) = 0.43), sex-specific analyses identified that the only significant differences in accuracy were between T3 females and the other three groups (T4 females, T3 males, and T4 males). There was no correlation between males’ accuracy and coach-rated decision making skill, and no difference in accuracy between selected and nonselected females. Reliability analyses comparing performance between weeks revealed an ICC of 0.75, a standard error of measurement of 3.41%, and a significant improvement from week 1 to week 2 among T4 males ( p = .018). Despite associations between accuracy and age, the test was not able to distinguish between more similar groups of athletes. Considering the nonrepresentative design of the test, the construct assessed was declarative game knowledge rather than decision making skill, with the results suggesting that the former is not critical for evaluating elite players. The performance improvement between weeks among T4 males reinforces that video-based designs should be used cautiously in high-performance sport. However, there may still be practical applications for video-based designs, such as in video review sessions or as a pedagogical tool. |
