The reliability of a functional agility test for water polo.

Tucher G, de Souza Castro FA, Garrido ND, Martins da Silva AJ - J Hum Kinet (2014)

Bottom Line: The CV average considering each individual was near 6-7%.As the FTAP contains some characteristics that create a degree of unpredictability, the same athlete may reach different performance results, increasing variability.An adjustment in the sample, familiarization and careful selection of subjects help to improve this situation and enhance the reliability of the indicators.

ABSTRACT
Few functional agility tests for water polo take into consideration its specific characteristics. The preliminary objective of this study was to evaluate the reliability of an agility test for water polo players. Fifteen players (16.3 ± 1.8 years old) with a minimum of two years of competitive experience were evaluated. A Functional Test for Agility Performance (FTAP) was designed to represent the context of this sport. Several trials were performed to familiarize the athlete with the movement. Two experienced coaches measured three repetitions of the FTAP. Descriptive statistics, repeated measures analysis of variance (ANOVA), 95% limit of agreement (LOA), intraclass correlation coefficient (ICC) and standard error of measurements (SEM) were used for data analysis. It was considered that certain criteria of reliability measures were met. There was no significant difference between the repetitions, which may be explained by an effect of the evaluator, the ability of the players or fatigue (p > 0.05). The ICC average from evaluators was high (0.88). The SEM varied between 0.13 s and 0.49 s. The CV average considering each individual was near 6-7%. These values depended on the condition of measurement. As the FTAP contains some characteristics that create a degree of unpredictability, the same athlete may reach different performance results, increasing variability. An adjustment in the sample, familiarization and careful selection of subjects help to improve this situation and enhance the reliability of the indicators.

Mentions: To evaluate the specific agility of the players the authors designed a Functional Test for Agility Performance (FTAP). The test is characterized by its open nature (Sheppard and Young, 2006; Veale et al., 2010; Young and Willey, 2010), since the athlete does not have prior knowledge of the direction of his displacement thus ensuring the randomness of movements generated by the passes made by another player. The test presents the subjects with high-intensity dislocation of short duration, similar to the situations indicated by Tan et al. (2009). The FTAP’s scheme is presented in Figure 1.
