Comparación entre la videografía y el método Sit and Reach para la valoración de la flexibilidad isquiotibial en deportistas escolares

Abstract

There are different test to evaluate flexibility of human movement. The comparison of sit and reach test and videogaphy measurement of hamstrings flexibility was the purpose of this study. 139 scholar football players, between 7 and 16 years old, were evaluated. Kappa coefficient shows little concordance between the two tests (0,022 (I.C. 95% -0,07 – 0,12)) which demonstrates that sit and reach test is not valid enough for hamstrings flexibility evaluation.
