Análise da qualidade do instrumento: sistema de observação do cruzamento – patinagem de velocidade

Abstract

O presente estudo teve como objetivo a criação de um instrumento que permita a recolha de dados para a análise da estabilidade da técnica de curva em patinagem de velocidade. O instrumento serve de registo dos comportamentos observados durante a execução dos primeiros três cruzamentos. Neste quadro, é fundamental a viabilidade e fiabilidade do instrumento. O instrumento foi composto por um sistema categorias e Formatos de Campo (Oliveira et al., 2001), com base em referências da metodologia observacional e modelos biomecânicos da patinagem de velocidade. O instrumento foi validado recorrendo ao Índice de Kappa (Anguera, 1993; Blanco, 1993 e 1997), com base nos registos de três observadores (interobservadores, 97%) e, para efeitos de precisão, de mais um perito (intraobservador, 99%). Os resultados garantem rigor e objetividade quando se descrevem os comportamentos observados. Devido aos elevados valores de concordância do índice Kappa que, variam entre 97% e 99%, é possível apurar a validade e fiabilidade do instrumento sendo adequado para observar os comportamentos técnicos dos patinadores quando realizam a curva.
