Objetivo.  El objetivo de esta investigacion ha sido valorar en ninos espanoles la fiabilidad del cuestionario de actividad fisica en ninos mayores (PAQ-C). Metodo.  Se utilizo como referencia la validacion de la version traducida al castellano del cuestionario de actividad fisica para adolescentes PAQ-A. En una muestra de 72 ninos entre 8 y 14 anos, se evaluo la fiabilidad test-retest del cuestionario PAQ-C en 3 mediciones, antes de la clase de educacion fisica (M1), 2 horas despues (M2) y al cabo de una semana (M3). La fiabilidad se calculo mediante el coeficiente de correlacion intraclase (ICC) y la consistencia interna mediante el Coeficiente α de Cronbach. Resultados : Los valores obtenidos en la puntuacion total del cuestionario reflejan un ICC superior a 0.73 en todas las comparaciones, con un intervalo de confianza al 95% que sigue indicando una fiabilidad buena o excelente. La consistencia interna mostro un coeficiente de α = 0,83.
