Validade e Fiabilidade de uma Bateria de Testes de Agilidade com Condução de Bola para Atletas de Futebol com Paralisia Cerebral

Abstract

The evaluation of motor skills such as agility, speed, balance, coordination, are of great importance for the development of specific skills in Football for Athletes with Cerebral Palsy (CP). However, there are no validated ball conduction agility tests for CP Football. The present study had as general objective to analyze the validity and reliability of an agility test battery with ball conduction for Football athletes with cerebral palsy. Participated in the study 35 football players with PC, from Brazil, Spain and Portugal. To analyze the content validity, Kappa coefficient was used, reliability was analyzed from the intraclass correlation index and Cronbach's alpha. The differences between the test and the retest were analyzed using the Wilcoxon test, the Spearman correlation coefficient was used to analyze the association between the four agility tests with ball conduction, as well as the association between the tests and the retest in each of the agility tests. The Kruskal-Wallis test was used to examine the differences between classes. For all tests, the statistical significance was set at p <0.05. Concerning the content validity of the agility test battery with ball conduction, there was excellent agreement regarding the "easy perception of the athletes", "applicability of the tests" and "reproducibility in the modality". Regarding reliability, all the tests presented ICC and Cronbach's alpha values higher than 0.90, being classified as excellent values. Significant, positive and moderate to very strong correlations were identified between the test and the retest and between the 4 tests. When we analyzed the differences between classes, we verified that there was no significant difference in performance as a function of the sport class. The present study demonstrated that the battery of tests is valid and reliable, being able to be applied in Soccer players with PC.
