CONFIABILIDAD DE LA EVALUACIÓN POR JUECES DEL VÍDEO DE LOS ELEMENTOS TÉCNICOS DE NADO SINCRONIZADO

ABSTRACT

Introduction:  In acrobatic, rhythmic and expressive gymnastics, the goal is performance and the score is given by judges. In synchronized swimming the panel is composed of seven judges who assess figures and fifteen judges who assess technical and free routines. Accordingly, the aim of this study was to verify the reliability of this strategy - the evaluation of technical elements in a synchronized swimming routine via video.

Method:  The study included three synchronized swimming athletes aged 17 to 18 and ten level A and B judges on the FINA list with at least ten years of experience in national and international events.

Results:  Cronbach’s Alpha coefficient was 0.85 for T1 (test) and 0.83 for T2 (retest), indicating high internal consistency above 0.70. As regards agreement between scores awarded at both T1 and T2, significant correlation (r: 0.530 p> 0.0005) was found between them, confirmed after Bland-Altman reliability analysis (bias: 0.0553334 95% of limit of agreement -1.25043 to 1.36110).

Conclusion:  The results of this study suggest that video is a reliable tool for training synchronized swimming judges. Level of Evidence II; Diagnostic studies - Investigating a diagnostic test.
